Organization and Nature of Business and Summary of Significant Accounting Policies (Notes)	9 Months Ended
	Sep. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	The accompanying unaudited consolidated financial statements have been prepared by West Bancorporation, Inc. (the Company) pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements have been condensed or omitted pursuant to such rules and regulations. Although management believes that the disclosures are adequate to make the information presented understandable, it is suggested that these interim consolidated financial statements be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on February 28, 2019. In the opinion of management, the accompanying consolidated financial statements of the Company contain all adjustments necessary to fairly present its financial position as of September 30, 2019 and December 31, 2018, net income, comprehensive income and changes in stockholders' equity for the three and nine months ended September 30, 2019 and 2018, and cash flows for the nine months ended September 30, 2019 and 2018. The results for these interim periods may not be indicative of results for the entire year or for any other period. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) established by the Financial Accounting Standards Board (FASB). References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification™, sometimes referred to as the Codification or ASC. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses for the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term are the fair value of financial instruments and the allowance for loan losses. The accompanying unaudited consolidated financial statements include the accounts of the Company, West Bank, West Bank's special purpose subsidiaries and West Bank's wholly-owned subsidiary WB Funding Corporation (which was liquidated in March 2018). All significant intercompany transactions and balances have been eliminated in consolidation. In accordance with GAAP, West Bancorporation Capital Trust I is recorded on the books of the Company using the equity method of accounting and is not consolidated. Current accounting developments: In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing right-of-use assets and lease liabilities on the balance sheet. For public companies, this update was effective for interim and annual periods beginning after December 15, 2018. The Company adopted this guidance in the first quarter of 2019. Upon adoption, the Company elected a practical expedient which allowed existing leases to retain their classification as operating leases. The Company also elected the option to account for lease and related non-lease components as a single lease component, and the option not to recognize right-of-use assets and lease liabilities arising from short-term leases (leases with terms of twelve months or less). Lease liabilities are measured at the present value of the remaining lease payments, discounted at the Company's incremental borrowing rate. The right-of-use asset is measured at the amount of the lease liability adjusted for any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term. Implementation of the guidance resulted in the recording of a right-of-use asset, included in premises and equipment, and an operating lease liability, included in other liabilities, on the consolidated balance sheet; however it did not have a material impact on the Company's other consolidated financial statements. See additional disclosures in Note 9. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). The amendments in this update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net carrying value at the amount expected to be collected on the financial assets. Under the updates, the income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount of financial assets. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis will be determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses will be added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses will be recorded as a credit loss expense for these assets. Off-balance-sheet arrangements such as commitments to extend credit, guarantees and standby letters of credit that are not considered derivatives under ASC 815 and are not unconditionally cancellable are also within the scope of this update. Credit losses relating to available for sale debt securities should be recorded through an allowance for credit losses. For public companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. An entity will apply the amendments in this update on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In October 2019, the FASB voted to approve amendments to the effective date of ASU No. 2016-13 for smaller reporting companies, as defined by the SEC, and other non-SEC reporting entities. The amendment will delay the effective date to fiscal years beginning after December 31, 2022, including interim periods within those fiscal periods. As the Company is a smaller reporting company, the delay will be applicable to the Company. The final ASU is expected to be issued in November 2019. The Company is developing its approach for determining the expected credit losses under the new guidance. The Company continues collecting and retaining historical loan and credit data and is currently evaluating alternative loss estimation models. While the Company currently cannot estimate the impact of adopting this standard, the Company expects the impact will be influenced by the composition, risk characteristics and quality of our loan and securities portfolios, as well as the general economic conditions and forecasts as of the adoption date. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this update modify the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. The update is effective for interim and annual periods in fiscal years beginning after December 15, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for the new disclosures. The removed and modified disclosures will be adopted on a retrospective basis, and the new disclosures will be adopted on a prospective basis. The adoption will not have a material effect on the Company’s consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Financial Instruments - Credit Losses (ASC 326), Derivatives and Hedging (ASC 815), and Financial Instruments (ASC 825). The amendments in the ASU improve the Codification by eliminating inconsistencies and providing clarifications. The amended guidance in this ASU related to the credit losses will be effective for fiscal years and interim periods beginning after December 15, 2019. The Company is currently evaluating the impact of the ASU on the Company's consolidated financial statements.

Earnings Per Share [Abstract]

Earnings per Common Share [Text Block]

Earnings per Common Share

Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflect the potential dilution that could occur if the Company's outstanding restricted stock units were vested. The dilutive effect was computed using the treasury stock method, which assumes all stock-based awards were exercised and the hypothetical proceeds from exercise were used by the Company to purchase common stock at the average market price during the period. The incremental shares, to the extent they would have been dilutive, were included in the denominator of the diluted earnings per common share calculation. The calculations of earnings per common share and diluted earnings per common share for the three and nine months ended September 30, 2019 and 2018 are presented in the following table.

(1)	All collateralized mortgage obligations and mortgage-backed securities consist of residential mortgage pass-through securities guaranteed by FHLMC or FNMA, real estate mortgage investment conduits guaranteed by FNMA, FHLMC or GNMA, and commercial mortgage pass-through securities guaranteed by the SBA.


(2)	Pass-through asset-backed securities guaranteed by the SBA.

Investment securities with an amortized cost of approximately $138,973 and $126,531 as of September 30, 2019 and December 31, 2018, respectively, were pledged to secure access to the Federal Reserve discount window, for public fund deposits, and for other purposes as required or permitted by law or regulation.

The amortized cost and fair value of investment securities available for sale as of September 30, 2019, by contractual maturity, are shown below. Certain securities have call features that allow the issuer to call the securities prior to maturity. Expected maturities may differ from contractual maturities for collateralized mortgage obligations, mortgage-backed securities and asset-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Therefore, collateralized mortgage obligations, mortgage-backed securities and asset-backed securities are not included in the maturity categories within the following maturity summary.



	September 30, 2019

As of September 30, 2019, the available for sale securities with unrealized losses included 27 collateralized mortgage obligation securities, seven mortgage-backed securities, three asset-backed securities, four collateralized loan obligation securities and three corporate notes. The Company believed the unrealized losses on securities available for sale as of September 30, 2019 were due to market conditions rather than reduced estimated cash flows. At September 30, 2019, the Company did not intend to sell these securities, did not anticipate that these securities will be required to be sold before anticipated recovery, and expected full principal and interest to be collected. Therefore, the Company did not consider these securities to have other than temporary impairment as of September 30, 2019.

Loans and Allowance for Loan Losses

	$	1,836,730		$	1,721,830

Real estate loans of approximately $850,000 and $800,000 were pledged as security for Federal Home Loan Bank (FHLB) advances as of September 30, 2019 and December 31, 2018, respectively.

Loans are stated at the principal amounts outstanding, net of unamortized loan fees and costs, with interest income recognized on the interest method based upon the terms of the loan. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Loans are reported by the portfolio segments identified above and are analyzed by management on this basis. All loan policies identified below apply to all segments of the loan portfolio.

Delinquencies are determined based on the payment terms of the individual loan agreements. The accrual of interest on past due and other impaired loans is generally discontinued at 90 days past due or when, in the opinion of management, the borrower may be unable to make all payments pursuant to contractual terms. Unless considered collectible, all interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income, if accrued in the current year, or charged to the allowance for loan losses, if accrued in the prior year. Generally, all payments received while a loan is on nonaccrual status are applied to the principal balance of the loan. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.

A loan is classified as a troubled debt restructured (TDR) loan when the Company separately concludes that a borrower is experiencing financial difficulties and a concession is granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden of the borrower's cash requirements, such as an extension of the payment terms beyond the original maturity date or a change in the interest rate charged. TDR loans with extended payment terms are accounted for as impaired until performance is established. A change to the interest rate would change the classification of a loan to a TDR loan if the restructured loan yields a rate that is below a market rate for that of a new loan with comparable risk. TDR loans with below-market rates are considered impaired until fully collected. TDR loans may also be reported as nonaccrual or 90 days past due if they are not performing per the restructured terms.

Based upon its ongoing assessment of credit quality within the loan portfolio, the Company maintains a Watch List, which includes loans classified as Doubtful, Substandard and Watch according to the Company's classification criteria. These loans involve the anticipated potential for payment defaults or collateral inadequacies. A loan on the Watch List is considered impaired when management believes it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. The amount of impairment, if any, and any subsequent changes are included in the allowance for loan losses.

TDR loans totaled $32 and $652 as of September 30, 2019 and December 31, 2018, respectively, and were included in the nonaccrual category. There were no loan modifications considered to be TDR that occurred during the three and nine months ended September 30, 2019 and the three months ended September 30, 2018. There was one loan modification considered to be TDR, with a pre- and post-modification recorded investment of $560, that occurred during the nine months ended September 30, 2018.

No TDR loans that were modified within the twelve months preceding September 30, 2019 have subsequently had a payment default. One TDR loan that was modified within the twelve months preceding September 30, 2018, with a recorded investment of $552, has subsequently had a payment default. A TDR loan is considered to have a payment default when it is past due 30 days or more.

The following table summarizes the recorded investment in impaired loans by segment, broken down by loans with no related allowance for loan losses and loans with a related allowance and the amount of that allowance as of September 30, 2019 and December 31, 2018.

All loans are subject to the assessment of a credit quality indicator. Risk ratings are assigned for each loan at the time of approval, and they change as circumstances dictate during the term of the loan. The Company utilizes a 9-point risk rating scale as shown below, with ratings 1 - 5 included in the Pass column, rating 6 included in the Watch column, ratings 7 - 8 included in the Substandard column and rating 9 included in the Doubtful column. All loans classified as impaired that are included in the specific evaluation of the allowance for loan losses are included in the Substandard column along with all other loans with ratings of 7 - 8.

Risk rating 1: The loan is secured by cash equivalent collateral.

Risk rating 2: The loan is secured by properly margined marketable securities, bonds or cash surrender value of life insurance.

Risk rating 3: The borrower is in strong financial condition and has strong debt service capacity. The loan is performing as agreed, and the financial characteristics and trends of the borrower exceed industry statistics.

Risk rating 4: The borrower's financial condition is satisfactory and stable. The borrower has satisfactory debt service capacity, and the loan is well secured. The loan is performing as agreed, and the financial characteristics and trends fall in line with industry statistics.

Risk rating 5: The borrower's financial condition is less than satisfactory. The loan is still generally paying as agreed, but strained cash flows may cause some slowness in payments. The collateral values adequately preclude loss on the loan. Financial characteristics and trends lag industry statistics. There may be noncompliance with loan covenants.

Risk rating 6: The borrower's financial condition is deficient. Payment delinquencies may be more common. Collateral values still protect from loss, but margins are narrow. The loan may be reliant on secondary sources of repayment, including liquidation of collateral and guarantor support.

Risk rating 7: The loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Well-defined weaknesses exist that jeopardize the liquidation of the debt. The Company is inadequately protected by the valuation or paying capacity of the collateral pledged. If deficiencies are not corrected, there is a distinct possibility that a loss will be sustained.

Risk rating 8: All the characteristics of rating 7 exist with the added condition that the loan is past due more than 90 days or there is reason to believe the Company will not receive its principal and interest according to the terms of the loan agreement.

Risk rating 9: All the weaknesses inherent in risk ratings 7 and 8 exist with the added condition that collection or liquidation, on the basis of currently known facts, conditions and values, is highly questionable and improbable. A loan reaching this category would most likely be charged off.

Credit quality indicators for all loans and the Company's risk rating process are dynamic and updated on a continuous basis. Risk ratings are updated as circumstances that could affect the repayment of an individual loan are brought to management's attention through an established monitoring process. Individual lenders initiate changes as appropriate for ratings 1 through 5, and changes for ratings 6 through 9 are initiated via communications with management. The likelihood of loss increases as the risk rating increases and is generally preceded by a loan appearing on the Watch List, which consists of all loans with a risk rating of 6 or worse. Written action plans with firm target dates for resolution of identified problems are maintained and reviewed on a quarterly basis for all segments of loans included on the Watch List.

In addition to the Company's internal credit monitoring practices and procedures, an outsourced independent credit review function is in place to further assess assigned internal risk classifications and monitor compliance with internal lending policies and procedures.

In all portfolio segments, the primary risks are that a borrower's income stream diminishes to the point that the borrower is not able to make scheduled principal and interest payments and any collateral securing the loan declines in value. The risk of declining collateral values is present for most types of loans.

Commercial loans consist primarily of loans to businesses for various purposes, including revolving lines to finance current operations, inventory and accounts receivable, and capital expenditure loans to finance equipment and other fixed assets. These loans generally have short maturities, have either adjustable or fixed interest rates, and are either unsecured or secured by inventory, accounts receivable and/or fixed assets. For commercial loans, the primary source of repayment is from the operation of the business.

Real estate loans include various types of loans for which the Company holds real property as collateral, and consist of loans on commercial properties and single and multifamily residences. Real estate loans are typically structured to mature or reprice every five to ten years with payments based on amortization periods up to 30 years. The majority of construction loans are to contractors and developers for construction of commercial buildings or residential real estate. These loans typically have maturities of up to 24 months. The Company's loan policy includes minimum appraisal and other credit guidelines.

Consumer loans include loans extended to individuals for household, family and other personal expenditures not secured by real estate. The majority of the Company's consumer lending is for vehicles, consolidation of personal debts and household improvements. The repayment source for consumer loans, including 1-4 family residential and home equity loans, is typically wages.

The allowance for loan losses is established through a provision for loan losses charged to expense. The allowance is an amount that management believes will be adequate to absorb probable losses on existing loans based on an evaluation of the collectability of loans and prior loss experience. This evaluation also takes into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, the review of specific problem loans, and the current economic conditions that may affect the borrower's ability to pay. Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. While management uses the best information available to make its evaluations, future adjustments to the allowance may be necessary if there are significant changes in economic conditions or the other factors relied upon.

The allowance for loan losses consists of specific and general components. The specific component relates to loans that meet the definition of impaired. The general component covers the remaining loans and is based on historical loss experience adjusted for qualitative factors such as delinquency trends, loan growth, economic elements and local market conditions. These same policies are applied to all segments of loans. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company's allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.

The following tables detail the changes in the allowance for loan losses by segment for the three and nine months ended September 30, 2019 and 2018.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative [Text Block]

Derivatives

The Company has entered into various interest rate swaps as part of its interest rate risk management strategy. The Company uses interest rate swap agreements to manage its exposures to the variability in certain interest payments due to interest rate movements. The interest rate swaps involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments. At December 31, 2018, the Company had three interest rate swaps with a total notional amount of $110,000 hedging the variable interest payments on certain borrowings and customer deposits. In the first nine months of 2019, the Company has entered into eight additional interest rate swaps. Four of these swaps with a total notional amount of $100,000 hedge the interest payments of rolling fixed-rate one- or three-month funding consisting of FHLB advances or brokered deposits. Three of these swaps with a total notional amount of $75,000 are forward-starting swaps to hedge the interest payments of rolling one-month funding consisting of FHLB advances or brokered deposits, with starting dates from December 2019 to September 2020. Lastly, the Company entered into one interest rate swap with a notional amount of $50,000 to hedge the interest payments of money market deposit accounts. The interest rate swaps are designated as cash flow hedges.

The Company is exposed to credit risk in the event of nonperformance by counterparties to the interest rate swaps, which is minimized by collateral-pledging provisions in the agreements. Derivative contracts are executed with a Credit Support Annex, which is a bilateral ratings-sensitive agreement that requires collateral postings at established credit threshold levels. These agreements protect the interests of the Company and its counterparties should either party suffer a credit rating deterioration. As of September 30, 2019 and December 31, 2018, the Company pledged $10,770 and $0, respectively, of collateral to the counterparty in the form of cash on deposit with a third party. The Company's counterparty was required to pledge $0 and $2,410 at September 30, 2019 and December 31, 2018, respectively. The Company estimates there will be approximately $155 reclassified from accumulated other comprehensive income (AOCI) to interest expense through the 12 months ending September 30, 2020. Interest rate swaps with a total notional amount of $70,000 were terminated in 2015, subject to termination fees totaling $541. The termination fees are being reclassified from accumulated other comprehensive income to interest expense over the remaining life of the underlying cash flows through June 2020.

The table below identifies the balance sheet category and fair values of the Company's derivative instruments designated as cash flow hedges as of September 30, 2019 and December 31, 2018.

Commitments and Contingencies

Financial instruments with off-balance-sheet risk: The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations that it uses for on-balance-sheet instruments. The Company's commitments consisted of the following approximate amounts as of September 30, 2019 and December 31, 2018.



	September 30, 2019		December 31, 2018

Leases of Lessee Disclosure [Text Block]

Leases

Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842) and all subsequent ASUs that modified Topic 842. The Company leases real estate for its main office, nine branch offices and office space for operations departments under various operating lease agreements. The lease agreements have maturity dates ranging from May 2021 to February 2033, some of which include options to renew at the Company's discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the measurement of the right-of-use asset and lease liability. The weighted average remaining life of the term of these leases was 7.9 years as of September 30, 2019.

The discount rate used in determining the lease liability for each individual lease was the FHLB fixed advance rate which corresponded with the remaining lease term as of January 1, 2019 for leases that existed at adoption and as of the lease commencement date for leases entered into subsequent to January 1, 2019. The weighted average discount rate used in the measurement of the operating lease liability was 3.16% as of September 30, 2019.

The total operating lease costs were $418 and $1,212 for the three and nine months ended September 30, 2019, respectively. The right-of-use asset and lease liability were $9,216 and $9,449 as of September 30, 2019, respectively.

Total estimated rental commitments for the operating leases were as follows as of September 30, 2019.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

Accounting guidance on fair value measurements and disclosures defines fair value and establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts business.

The Company's balance sheet contains investment securities available for sale and derivative instruments that are recorded at fair value on a recurring basis. The three-level valuation hierarchy for disclosure of fair value is as follows:

Level 1 uses quoted market prices in active markets for identical assets or liabilities.

Level 2 uses observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3 uses unobservable inputs that are not corroborated by market data.

The Company's policy is to recognize transfers between levels at the end of each reporting period, if applicable. There were no transfers between levels of the fair value hierarchy during the nine months ended September 30, 2019.

The following is a description of valuation methodologies used for financial assets and liabilities recorded at fair value on a recurring basis.

Investment securities available for sale: When available, quoted market prices are used to determine the fair value of investment securities (Level 1). If quoted market prices are not available, the Company determines fair value based on various sources and may apply matrix pricing with observable prices for similar bonds where a price for the identical bond is not observable (Level 2). The fair values of these securities are determined by pricing models that consider observable market data such as interest rate volatilities, LIBOR yield curve, credit spreads, prices from market makers and live trading systems. For the corporate bond portfolio, the Company has elected to use a matrix pricing model as a practical expedient to individual quoted market prices.

Generally, management obtains the fair value of investment securities at the end of each reporting period via a third-party pricing service. Management reviewed the valuation process used by the third party and believed the process was valid. On a quarterly basis, management corroborates the fair values of a randomly selected sample of investment securities by obtaining pricing from an independent financial market data vendor and comparing the two sets of fair values. Any significant variances are reviewed and investigated. For a sample of securities, prices are further validated by management by obtaining details of the inputs used by the pricing service. Those inputs were independently tested, and management concluded the fair values were consistent with GAAP requirements and the investment securities were properly classified in the fair value hierarchy.

Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative positions are classified within Level 2 of the fair value hierarchy and are valued using models generally accepted in the financial services industry and that use actively quoted or observable market input values from external market data providers and/or non-binding broker-dealer quotations. The fair value of the derivatives is determined using discounted cash flow models. These models’ key assumptions include the contractual terms of the respective contract along with significant observable inputs, including interest rates, yield curves, nonperformance risk and volatility.

The following tables present the balances of financial assets and liabilities measured at fair value on a recurring basis by level as of September 30, 2019 and December 31, 2018.

Certain assets are measured at fair value on a nonrecurring basis. That is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). As of both September 30, 2019 and December 31, 2018, impaired loans with a fair value adjustment had a net book value of $0. Impaired loans are classified within Level 3 of the fair value hierarchy and are evaluated and valued at the lower of cost or fair value when the loan is identified as impaired. Fair value is measured based on the value of the collateral securing these loans. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered include aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan and may be discounted based on management's opinions concerning market developments or the client's business.

GAAP requires disclosure of the fair value of financial assets and financial liabilities, including those that are not measured and reported at fair value on a recurring or nonrecurring basis. The following table presents the carrying amounts and approximate fair values of financial assets and liabilities as of September 30, 2019 and December 31, 2018.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The accompanying unaudited consolidated financial statements have been prepared by West Bancorporation, Inc. (the Company) pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements have been condensed or omitted pursuant to such rules and regulations. Although management believes that the disclosures are adequate to make the information presented understandable, it is suggested that these interim consolidated financial statements be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on February 28, 2019. In the opinion of management, the accompanying consolidated financial statements of the Company contain all adjustments necessary to fairly present its financial position as of September 30, 2019 and December 31, 2018, net income, comprehensive income and changes in stockholders' equity for the three and nine months ended September 30, 2019 and 2018, and cash flows for the nine months ended September 30, 2019 and 2018. The results for these interim periods may not be indicative of results for the entire year or for any other period. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) established by the Financial Accounting Standards Board (FASB). References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification™, sometimes referred to as the Codification or ASC.
Use of Estimates, Policy [Policy Text Block]	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses for the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term are the fair value of financial instruments and the allowance for loan losses
Consolidation, Policy [Policy Text Block]	The accompanying unaudited consolidated financial statements include the accounts of the Company, West Bank, West Bank's special purpose subsidiaries and West Bank's wholly-owned subsidiary WB Funding Corporation (which was liquidated in March 2018). All significant intercompany transactions and balances have been eliminated in consolidation. In accordance with GAAP, West Bancorporation Capital Trust I is recorded on the books of the Company using the equity method of accounting and is not consolidated.
New Accounting Pronouncements, Policy [Policy Text Block]	Current accounting developments: In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing right-of-use assets and lease liabilities on the balance sheet. For public companies, this update was effective for interim and annual periods beginning after December 15, 2018. The Company adopted this guidance in the first quarter of 2019. Upon adoption, the Company elected a practical expedient which allowed existing leases to retain their classification as operating leases. The Company also elected the option to account for lease and related non-lease components as a single lease component, and the option not to recognize right-of-use assets and lease liabilities arising from short-term leases (leases with terms of twelve months or less). Lease liabilities are measured at the present value of the remaining lease payments, discounted at the Company's incremental borrowing rate. The right-of-use asset is measured at the amount of the lease liability adjusted for any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term. Implementation of the guidance resulted in the recording of a right-of-use asset, included in premises and equipment, and an operating lease liability, included in other liabilities, on the consolidated balance sheet; however it did not have a material impact on the Company's other consolidated financial statements. See additional disclosures in Note 9. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). The amendments in this update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net carrying value at the amount expected to be collected on the financial assets. Under the updates, the income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount of financial assets. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis will be determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses will be added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses will be recorded as a credit loss expense for these assets. Off-balance-sheet arrangements such as commitments to extend credit, guarantees and standby letters of credit that are not considered derivatives under ASC 815 and are not unconditionally cancellable are also within the scope of this update. Credit losses relating to available for sale debt securities should be recorded through an allowance for credit losses. For public companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. An entity will apply the amendments in this update on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. In October 2019, the FASB voted to approve amendments to the effective date of ASU No. 2016-13 for smaller reporting companies, as defined by the SEC, and other non-SEC reporting entities. The amendment will delay the effective date to fiscal years beginning after December 31, 2022, including interim periods within those fiscal periods. As the Company is a smaller reporting company, the delay will be applicable to the Company. The final ASU is expected to be issued in November 2019. The Company is developing its approach for determining the expected credit losses under the new guidance. The Company continues collecting and retaining historical loan and credit data and is currently evaluating alternative loss estimation models. While the Company currently cannot estimate the impact of adopting this standard, the Company expects the impact will be influenced by the composition, risk characteristics and quality of our loan and securities portfolios, as well as the general economic conditions and forecasts as of the adoption date. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this update modify the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. The update is effective for interim and annual periods in fiscal years beginning after December 15, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for the new disclosures. The removed and modified disclosures will be adopted on a retrospective basis, and the new disclosures will be adopted on a prospective basis. The adoption will not have a material effect on the Company’s consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Financial Instruments - Credit Losses (ASC 326), Derivatives and Hedging (ASC 815), and Financial Instruments (ASC 825). The amendments in the ASU improve the Codification by eliminating inconsistencies and providing clarifications. The amended guidance in this ASU related to the credit losses will be effective for fiscal years and interim periods beginning after December 15, 2019. The Company is currently evaluating the impact of the ASU on the Company's consolidated financial statements.
Earnings Per Share, Policy [Policy Text Block]	Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflect the potential dilution that could occur if the Company's outstanding restricted stock units were vested. The dilutive effect was computed using the treasury stock method, which assumes all stock-based awards were exercised and the hypothetical proceeds from exercise were used by the Company to purchase common stock at the average market price during the period. The incremental shares, to the extent they would have been dilutive, were included in the denominator of the diluted earnings per common share calculation.
Financing Receivable, Fee and Interest Income [Policy Text Block]	Loans are stated at the principal amounts outstanding, net of unamortized loan fees and costs, with interest income recognized on the interest method based upon the terms of the loan. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Loans are reported by the portfolio segments identified above and are analyzed by management on this basis.
Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy [Policy Text Block]	Delinquencies are determined based on the payment terms of the individual loan agreements. The accrual of interest on past due and other impaired loans is generally discontinued at 90 days past due or when, in the opinion of management, the borrower may be unable to make all payments pursuant to contractual terms. Unless considered collectible, all interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income, if accrued in the current year, or charged to the allowance for loan losses, if accrued in the prior year. Generally, all payments received while a loan is on nonaccrual status are applied to the principal balance of the loan. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Troubled Debt Restructuring [Policy Text Block]	A loan is classified as a troubled debt restructured (TDR) loan when the Company separately concludes that a borrower is experiencing financial difficulties and a concession is granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden of the borrower's cash requirements, such as an extension of the payment terms beyond the original maturity date or a change in the interest rate charged. TDR loans with extended payment terms are accounted for as impaired until performance is established. A change to the interest rate would change the classification of a loan to a TDR loan if the restructured loan yields a rate that is below a market rate for that of a new loan with comparable risk. TDR loans with below-market rates are considered impaired until fully collected. TDR loans may also be reported as nonaccrual or 90 days past due if they are not performing per the restructured terms.
Impaired Financing Receivable, Policy [Policy Text Block]	Based upon its ongoing assessment of credit quality within the loan portfolio, the Company maintains a Watch List, which includes loans classified as Doubtful, Substandard and Watch according to the Company's classification criteria. These loans involve the anticipated potential for payment defaults or collateral inadequacies. A loan on the Watch List is considered impaired when management believes it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. The amount of impairment, if any, and any subsequent changes are included in the allowance for loan losses.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	The allowance for loan losses is established through a provision for loan losses charged to expense. The allowance is an amount that management believes will be adequate to absorb probable losses on existing loans based on an evaluation of the collectability of loans and prior loss experience. This evaluation also takes into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, the review of specific problem loans, and the current economic conditions that may affect the borrower's ability to pay. Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. While management uses the best information available to make its evaluations, future adjustments to the allowance may be necessary if there are significant changes in economic conditions or the other factors relied upon. The allowance for loan losses consists of specific and general components. The specific component relates to loans that meet the definition of impaired. The general component covers the remaining loans and is based on historical loss experience adjusted for qualitative factors such as delinquency trends, loan growth, economic elements and local market conditions. These same policies are applied to all segments of loans. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company's allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
Fair Value Measurement, Policy [Policy Text Block]	Accounting guidance on fair value measurements and disclosures defines fair value and establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts business. The Company's balance sheet contains investment securities available for sale and derivative instruments that are recorded at fair value on a recurring basis. The three-level valuation hierarchy for disclosure of fair value is as follows: Level 1 uses quoted market prices in active markets for identical assets or liabilities. Level 2 uses observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3 uses unobservable inputs that are not corroborated by market data. The Company's policy is to recognize transfers between levels at the end of each reporting period, if applicable. There were no transfers between levels of the fair value hierarchy during the nine months ended September 30, 2019. The following is a description of valuation methodologies used for financial assets and liabilities recorded at fair value on a recurring basis. Investment securities available for sale: When available, quoted market prices are used to determine the fair value of investment securities (Level 1). If quoted market prices are not available, the Company determines fair value based on various sources and may apply matrix pricing with observable prices for similar bonds where a price for the identical bond is not observable (Level 2). The fair values of these securities are determined by pricing models that consider observable market data such as interest rate volatilities, LIBOR yield curve, credit spreads, prices from market makers and live trading systems. For the corporate bond portfolio, the Company has elected to use a matrix pricing model as a practical expedient to individual quoted market prices. Generally, management obtains the fair value of investment securities at the end of each reporting period via a third-party pricing service. Management reviewed the valuation process used by the third party and believed the process was valid. On a quarterly basis, management corroborates the fair values of a randomly selected sample of investment securities by obtaining pricing from an independent financial market data vendor and comparing the two sets of fair values. Any significant variances are reviewed and investigated. For a sample of securities, prices are further validated by management by obtaining details of the inputs used by the pricing service. Those inputs were independently tested, and management concluded the fair values were consistent with GAAP requirements and the investment securities were properly classified in the fair value hierarchy. Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative positions are classified within Level 2 of the fair value hierarchy and are valued using models generally accepted in the financial services industry and that use actively quoted or observable market input values from external market data providers and/or non-binding broker-dealer quotations. The fair value of the derivatives is determined using discounted cash flow models. These models’ key assumptions include the contractual terms of the respective contract along with significant observable inputs, including interest rates, yield curves, nonperformance risk and volatility.
Fair Value Transfer, Policy [Policy Text Block]	The Company's policy is to recognize transfers between levels at the end of each reporting period, if applicable.
Fair Value of Financial Instruments, Policy [Policy Text Block]	GAAP requires disclosure of the fair value of financial assets and financial liabilities, including those that are not measured and reported at fair value on a recurring or nonrecurring basis.
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]	The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations that it uses for on-balance-sheet instruments.
