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, 2019 filed with the SEC on February 27, 2020. 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 March 31, 2020 and December 31, 2019 and net income, comprehensive income, changes in stockholders' equity and cash flows for the three months ended March 31, 2020 and 2019 . 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 and West Bank's special purpose subsidiaries. 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 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 is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are 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. In December 2019, the FASB issued ASU No. 2019-10, Financial Instruments-Credit Losses (Topic 326). This update amends the effective date of ASU No. 2016-13 for certain entities, including smaller reporting companies until fiscal years beginning after December 15, 2022, including interim periods within those fiscal periods. Early adoption is permitted. The one-time determination date for identifying as a smaller reporting company was November 15, 2019. The Company met the definition of a smaller reporting company as of this date and plans to adopt the standard with the amended effective date. The Company does not plan to early adopt this standard, but continues to work through implementation. The Company continues collecting and retaining loan and credit data and evaluating various loss estimation models. While we currently cannot reasonably estimate the impact of adopting this standard, we expect the impact will be influenced by the composition, 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 the 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 did 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 the Company for fiscal years and interim periods beginning after December 15, 2022. The Company is currently evaluating the impact of the ASU on the Company’s consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this update provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of the reference rate reform 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 months ended March 31, 2020 and 2019 are presented in the following table. Three Months Ended March 31, (in thousands, except per share data) 2020 2019 Net income $ 8,089 $ 6,899 Weighted average common shares outstanding 16,386 16,300 Weighted average effect of restricted stock units outstanding 131 80 Diluted weighted average common shares outstanding 16,517 16,380 Basic earnings per common share $ 0.49 $ 0.42 Diluted earnings per common share $ 0.49 $ 0.42 Number of anti-dilutive common stock equivalents excluded from diluted earnings per share computation 157 225

(2) Pass-through asset-backed securities guaranteed by the SBA, representing participating interests in pools of commercial working capital and equipment loans. Investment securities with an amortized cost of approximately $229,634 and $148,257 as of March 31, 2020 and December 31, 2019 , 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 March 31, 2020 , 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.

Collateralized loan obligations are debt securities backed by pools of senior secured commercial loans to a diverse group of companies across a broad spectrum of industries. At March 31, 2020, the Company only owned collateralized loan obligations that were AAA or AA rated. The Company believed the unrealized losses on securities available for sale as of March 31, 2020 were due to market conditions rather than reduced estimated cash flows. At March 31, 2020, 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 March 31, 2020 .

Loans and Allowance for Loan Losses [Abstract]
Loans and Allowance for Loan Losses [Text Block]	Loans and Allowance for Loan Losses Loans consisted of the following segments as of March 31, 2020 and December 31, 2019 . March 31, 2020 December 31, 2019 Commercial $ 443,759 $ 431,044 Real estate: Construction, land and land development 278,734 264,193 1-4 family residential first mortgages 57,802 54,475 Home equity 11,835 12,380 Commercial 1,197,915 1,175,024 Consumer and other 6,542 6,787 1,996,587 1,943,903 Net unamortized fees and costs (2,155 ) (2,240 ) $ 1,994,432 $ 1,941,663 Real estate loans of approximately $960,000 and $910,000 were pledged as security for Federal Home Loan Bank (FHLB) advances as of March 31, 2020 and December 31, 2019 , 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. On March 22, 2020, federal banking regulators issued an interagency statement that included guidance on their approach for the accounting of loan modifications in light of the economic impact of the Coronavirus Disease 2019 (COVID-19) pandemic. The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented. The agencies confirmed in working with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. 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 $0 and $4 as of March 31, 2020 and December 31, 2019 , respectively, and were included in the nonaccrual category. There were no loan modifications considered to be TDR that occurred during the three months ended March 31, 2020 and 2019 . No TDR loans that were modified within the twelve months preceding March 31, 2020 have subsequently had a payment default. One TDR loan that was modified within the twelve months preceding March 31, 2019 , with a recorded investment of $537 , 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 March 31, 2020 and December 31, 2019 .

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 months ended March 31, 2020 and 2019 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative [Text Block]	Derivatives The Company has entered into various interest rate swap agreements as part of its interest rate risk management strategy. The Company uses interest rate swaps to manage its interest rate risk exposure on certain loans, variable-rate and short-term borrowings, and deposits due to interest rate movements. The notional amounts of the interest rate swaps do not represent amounts exchanged by the counterparties, but rather, the notional amount is used to determine, along with other terms of the derivative, the amounts to be exchanged between the counterparties. Interest Rate Swaps Designated as a Cash Flow Hedge: As of both March 31, 2020 and December 31, 2019 , the Company had interest rate swaps designated as cash flow hedges with a total notional amount of $335,000 . As of March 31, 2020 , the Company had swaps with a total notional amount of $125,000 that hedge the interest payments of rolling fixed-rate one- or three-month funding consisting of FHLB advances or brokered deposits, and forward starting swaps with a total notional amount of $50,000 , which will hedge the interest payments of rolling one-month funding consisting of FHLB advances or brokered deposits, with starting dates ranging from June 2020 to September 2020. Also as of March 31, 2020 , the Company had swaps with a total notional amount of $50,000 that effectively convert variable-rate FHLB advances and junior subordinated notes to fixed-rate debt, and swaps with a total notional amount of $110,000 that hedge the interest payments of certain deposit accounts. Derivatives Not Designated as Accounting Hedges: To accommodate customer need, the Company on occasion offers loan level interest rate swaps to its customers and offsets its exposure from such contracts by entering into mirror image swaps with a swap counterparty (back-to-back swap program). The interest rate swaps are free-standing derivatives and are recorded at fair value. The Company enters into a floating-rate loan and a fixed-rate swap with our customer. Simultaneously, the Company enters into an offsetting fixed-rate swap with a swap counterparty. In connection with each swap transaction, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay a swap counterparty the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These transactions allow the Company’s customers to effectively convert variable-rate loans to fixed-rate loans. The customer accommodations and any offsetting swaps are treated as non-hedging derivative instruments which do not qualify for hedge accounting. The table below identifies the balance sheet category and fair values of the Company's derivative instruments as of March 31, 2020 and December 31, 2019 . Notional Amount Fair Value Balance Sheet Category Weighted Average Floating Rate Weighted Average Fixed Rate Weighted Average Maturity - Years Cash flow hedges: March 31, 2020 Interest rate swaps $ 285,000 $ (23,060 ) Other Liabilities 1.08 % 2.28 % 5.2 Forward-starting interest rate swaps (1) 50,000 (3,600 ) Other Liabilities — 1.74 % 5.9 December 31, 2019 Interest rate swaps $ 215,000 $ (5,786 ) Other Liabilities 1.84 % 2.26 % 5.5 Interest rate swaps 70,000 403 Other Assets 2.62 % 2.37 % 5.2 Forward starting interest rate swaps (1) 50,000 (343 ) Other Liabilities — 1.74 % 6.1 Non-hedging derivatives: March 31, 2020 Interest rate swaps - counterparty $ 32,389 $ 1,055 Other Assets 2.75 % 3.36 % 10.0 Interest rate swaps - loan customer 32,389 (1,055 ) Other Liabilities 2.75 % 3.36 % 10.0 (1)The fixed rate for forward starting swaps represents the fixed rate to be paid beginning on the scheduled start dates of the swaps. No interest payments were required related to these swaps in 2019 or 2020. The following table identifies the pre-tax gains or losses recognized on the Company's derivative instruments designated as cash flow hedges for the three months ended March 31, 2020 and 2019 . Reclassified from AOCI into Income Amount of Pre-tax Gain (Loss) Recognized in OCI Amount of Gain (Loss) Three Months Ended March 31, Three Months Ended March 31, 2020 2019 Category 2020 2019 Interest rate swaps $ (21,258 ) $ (2,441 ) Interest Expense $ (341 ) $ 114 The Company estimates there will be approximately $3,437 reclassified from accumulated other comprehensive income (AOCI) to interest expense through the 12 months ending March 31, 2021 related to cash flow hedges. The Company is exposed to credit risk in the event of nonperformance by interest rate swap counterparties, which is minimized by collateral-pledging provisions in the agreements. Derivative contracts with swap counterparties 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 March 31, 2020 and December 31, 2019 , the Company pledged $28,570 and $6,570 , respectively, of collateral to the counterparties in the form of cash on deposit with a third party. The interest rate swap product with the borrower is cross collateralized with the underlying loan and therefore there is no posted collateral under swap contracts with customers.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	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 March 31, 2020 and December 31, 2019 . March 31, 2020 December 31, 2019 Commitments to extend credit $ 734,153 $ 672,117 Standby letters of credit 7,538 8,029 $ 741,691 $ 680,146 West Bank previously executed Mortgage Partnership Finance (MPF) Master Commitments (Commitments) with the FHLB of Des Moines to deliver residential mortgage loans and to guarantee the payment of any realized losses that exceed the FHLB's first loss account for mortgages delivered under the Commitments.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements Fair value is defined as 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 three months ended March 31, 2020 . 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. 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 accounted for as cash flow hedges, as well as interest rate swaps which are accounted for as non-hedging derivatives. 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 March 31, 2020 and December 31, 2019 . March 31, 2020 Total Level 1 Level 2 Level 3 Financial assets: Investment securities available for sale: State and political subdivisions $ 37,227 $ — $ 37,227 $ — Collateralized mortgage obligations 192,665 — 192,665 — Mortgage-backed securities 73,316 — 73,316 — Asset-backed securities 16,302 — 16,302 — Collateralized loan obligations 52,610 — 52,610 — Corporate notes and other investments 300 — 300 — Derivative instruments, interest rate swaps 1,055 — 1,055 — Financial liabilities: Derivative instruments, interest rate swaps $ 27,715 $ — $ 27,715 $ — December 31, 2019 Total Level 1 Level 2 Level 3 Financial assets: Investment securities available for sale: State and political subdivisions $ 47,178 $ — $ 47,178 $ — Collateralized mortgage obligations 181,921 — 181,921 — Mortgage-backed securities 73,030 — 73,030 — Asset-backed securities 17,600 — 17,600 — Collateralized loan obligations 64,832 — 64,832 — Corporate notes and other investments 14,017 — 14,017 — Derivative instruments, interest rate swaps 403 — 403 — Financial liabilities: Derivative instrument, interest rate swap $ 6,129 $ — $ 6,129 $ — 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 March 31, 2020 and December 31, 2019 , there were no impaired loans that had a fair value adjustment. 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 March 31, 2020 and December 31, 2019 .

Risks and Uncertainties [Abstract]
Concentration Risk, Credit Risk, Policy [Policy Text Block]	10. Risks and Uncertainties On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a global pandemic, which continues to spread throughout the United States and around the world. The COVID-19 pandemic has adversely affected, and may continue to adversely affect economic activity globally, nationally and locally. Actions taken around the world to help mitigate the spread of COVID-19 include restrictions on travel, quarantines in certain areas, and forced closures for certain types of public places and businesses. COVID-19 and actions taken to mitigate the spread of it have had and are expected to continue to have an adverse impact on the economies and financial markets of many countries, including the geographical area in which the Company operates. Due to the COVID-19 pandemic, market interest rates have declined significantly, with the 10-year Treasury bond falling below 1.00 percent on March 3, 2020 for the first time. Such events also may adversely affect business and consumer confidence, generally, and the Company and its customers, and their respective suppliers, vendors and processors, may be adversely affected. On March 3, 2020, the Federal Open Market Committee reduced the targeted federal funds interest rate range by 50 basis points to 1.00 percent to 1.25 percent. This range was further reduced to 0 percent to 0.25 percent on March 16, 2020. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted to, among other provisions, provide emergency assistance for individuals, families and businesses affected by the COVID-19 pandemic. These reductions in interest rates and other effects of the COVID-19 pandemic may adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is reasonably possible that estimates made in the financial statements could be materially and adversely impacted in the near term as a result of these conditions, including expected credit losses on loan receivables.

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, 2019 filed with the SEC on February 27, 2020. 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 March 31, 2020 and December 31, 2019 and net income, comprehensive income, changes in stockholders' equity and cash flows for the three months ended March 31, 2020 and 2019 . 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 and West Bank's special purpose subsidiaries. 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 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 is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are 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. In December 2019, the FASB issued ASU No. 2019-10, Financial Instruments-Credit Losses (Topic 326). This update amends the effective date of ASU No. 2016-13 for certain entities, including smaller reporting companies until fiscal years beginning after December 15, 2022, including interim periods within those fiscal periods. Early adoption is permitted. The one-time determination date for identifying as a smaller reporting company was November 15, 2019. The Company met the definition of a smaller reporting company as of this date and plans to adopt the standard with the amended effective date. The Company does not plan to early adopt this standard, but continues to work through implementation. The Company continues collecting and retaining loan and credit data and evaluating various loss estimation models. While we currently cannot reasonably estimate the impact of adopting this standard, we expect the impact will be influenced by the composition, 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 the 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 did 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 the Company for fiscal years and interim periods beginning after December 15, 2022. The Company is currently evaluating the impact of the ASU on the Company’s consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this update provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of the reference rate reform 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. On March 22, 2020, federal banking regulators issued an interagency statement that included guidance on their approach for the accounting of loan modifications in light of the economic impact of the Coronavirus Disease 2019 (COVID-19) pandemic. The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented. The agencies confirmed in working with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs.
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]	Fair value is defined as 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 three months ended March 31, 2020 . 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. 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 accounted for as cash flow hedges, as well as interest rate swaps which are accounted for as non-hedging derivatives. 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.
