Basis of Presentation [Abstract]
Basis of Presentation [Text Block]	Basis of Presentation 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. 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, 2014 . In the opinion of management, the accompanying consolidated financial statements contain all adjustments necessary to fairly present the financial position as of June 30, 2015 and December 31, 2014 , and net income and comprehensive income for the three and six months ended June 30, 2015 and 2014 , and cash flows for the six months ended June 30, 2015 and 2014 . 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 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 and other than temporary impairment (OTTI) 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 wholly-owned subsidiary WB Funding Corporation (which owns an interest in a limited liability company). West Bank's 99.99 percent owned subsidiary ICD IV, LLC (a community development entity) was liquidated during the third quarter of 2014 because the underlying loan matured. 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 January 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-04, Receivables—Troubled Debt Restructuring by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The update clarifies when an in substance foreclosure occurs, that is, when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan. This is the point when the consumer mortgage loan should be derecognized and the real property recognized. For public companies, this update was effective for interim and annual periods beginning after December 31, 2014. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 660): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs—Contracts with Customers (Subtopic 340-40) . The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. For public companies, this update was originally effective for interim and annual periods beginning after December 15, 2016. In July 2015, the FASB voted to delay the effective date of this ASU by one year. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update simplifies the presentation of debt issuance costs by requiring that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2015, and is to be applied retrospectively. Early adoption is permitted. The Company has determined that this guidance will not have a material impact on the Company's consolidated financial statements.

Earnings per Common 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 six months ended June 30, 2015 and 2014 are presented in the following table. Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Net income $ 5,272 $ 4,739 $ 10,375 $ 9,139 Weighted average common shares outstanding 16,054 16,002 16,037 15,990 Weighted average effect of restricted stock units outstanding 39 37 52 46 Diluted weighted average common shares outstanding 16,093 16,039 16,089 16,036 Basic earnings per common share $ 0.33 $ 0.30 $ 0.65 $ 0.57 Diluted earnings per common share $ 0.33 $ 0.30 $ 0.65 $ 0.57

Investment securities with an amortized cost of approximately $80,658 and $4,805 as of June 30, 2015 and December 31, 2014 , 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 increase in the amount of pledged investment securities at June 30, 2015 compared to December 31, 2014 was primarily due to an increase in public fund deposits. The amortized cost and fair value of investment securities available for sale as of June 30, 2015 , 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 and mortgage-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The Company believes the unrealized losses on investments available for sale and held to maturity as of June 30, 2015 , were due to market conditions, rather than reduced estimated cash flows. The Company does not intend to sell these securities, does not anticipate that these securities will be required to be sold before anticipated recovery, and expects full principal and interest to be collected. Therefore, the Company does not consider these investments to have OTTI as of June 30, 2015 .

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 June 30, 2015 and December 31, 2014 . June 30, 2015 December 31, 2014 Commercial $ 334,933 $ 316,908 Real estate: Construction, land and land development 148,786 154,490 1-4 family residential first mortgages 51,938 53,497 Home equity 21,091 24,500 Commercial 652,487 625,938 Consumer and other loans 8,905 9,318 1,218,140 1,184,651 Net unamortized fees and costs (762 ) (606 ) $ 1,217,378 $ 1,184,045 Real estate loans of approximately $610,000 and $590,000 were pledged as security for Federal Home Loan Bank (FHLB) advances as of June 30, 2015 and December 31, 2014 , 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 those outstanding loan balances. 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. 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 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. A loan is classified as a troubled debt restructured (TDR) loan when the Company concludes that a borrower is experiencing financial difficulties and a concession was granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden on 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 past due 90 days if they are not performing per the restructured terms. The table below presents the TDR loans by segment as of June 30, 2015 and December 31, 2014 . June 30, 2015 December 31, 2014 Troubled debt restructured loans (1) : Commercial $ 109 $ — Real estate: Construction, land and land development 351 376 1-4 family residential first mortgages 98 86 Home equity — — Commercial 501 557 Consumer and other loans — — Total troubled debt restructured loans $ 1,059 $ 1,019 (1) There were three TDR loans as of June 30, 2015 and two TDR loans as of December 31, 2014 , with balances of $688 and $643 , respectively, categorized as nonaccrual. There was one loan modification considered to be TDR that occurred during the three months ended June 30, 2015 , and two loan modifications considered to be TDR that occurred during the six months ended June 30, 2015 with pre- and post-modification recorded investments of $20 and $130 , respectively. There were no loan modifications considered to be TDR during the three and six months ended June 30, 2014 . One TDR loan that was modified within the twelve months preceding June 30, 2015 , with a recorded investment of $110 , has subsequently had a payment default. No TDR loans that were modified within the twelve months preceding June 30, 2014 have 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 and loans with a related allowance and the amount of that allowance as of June 30, 2015 and December 31, 2014 .

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 is in satisfactory financial condition and has satisfactory debt service capacity. The loan is performing as agreed, and the financial characteristics and trends of the borrower 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 criticized loans. 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 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. Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. 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. 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 six months ended June 30, 2015 and 2014 .

Derivatives [Abstract]
Derivative [Text Block]	Derivatives The Company uses interest rate swap agreements to assist in its interest rate risk management. 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. The Company has variable rate FHLB advances, which create exposure to variability in interest payments due to changes in interest rates. In December 2012, to manage the interest rate risk related to the variability of interest payments, the Company entered into three forward-starting interest rate swap transactions, with a total notional amount of $80,000 . The interest rate swaps effectively convert $80,000 of variable rate FHLB advances to fixed rate debt as of the forward-starting dates. The three swap transactions were designated as cash flow hedges of the changes in cash flows attributable to changes in LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on the underlying FHLB advances with quarterly interest rate reset dates. One interest rate swap, with a notional amount of $25,000 , became effective in December 2014 and was subsequently terminated in March 2015, subject to a termination fee of $158 . A second interest rate swap, with a notional amount of $25,000 , was terminated in June 2015, prior to its effective date and subject to a termination fee of $383 . The third interest rate swap, with a notional amount of $30,000 , will become effective in December 2015. The termination fees will be reclassified from accumulated other comprehensive income to interest expense over the remaining life of the underlying cash flows, through December 2019 and June 2020. In June 2013, the Company entered into a forward-starting interest rate swap transaction with a total notional amount of $20,000 , to effectively convert its $20,000 variable rate junior subordinated notes to fixed rate debt as of the forward-starting date of the swap transaction. The effective date of this swap was June 30, 2014, and it was terminated in September 2014, when the fair value was $0 . At the inception of each hedge transaction, the Company represented that the underlying principal balance would remain outstanding throughout the hedge transaction, making it probable that sufficient LIBOR-based interest payments would exist through the maturity date of the swaps. The cash flow hedges were determined to be fully effective during the remaining terms of the swaps. Therefore, the aggregate fair value of the remaining swap is recorded in other assets or other liabilities with changes in market value recorded in other comprehensive income, net of deferred taxes. See Note 9 for additional fair value information and disclosures. The amount included in accumulated other comprehensive income for the remaining hedge will be reclassified to interest expense should the hedge no longer be considered effective. No amount of ineffectiveness was included in net income for the six months ended June 30, 2015 or 2014 , and the Company estimates there will be approximately $304 of cash payments and reclassification from accumulated other comprehensive income (loss) to interest expense through June 30, 2016. The Company will continue to assess the effectiveness of the remaining hedge on a quarterly basis. The Company is exposed to credit risk in the event of nonperformance by the interest rate swap counterparty. The Company minimizes this risk by entering into derivative contracts with only large, stable financial institutions, and the Company has not experienced, and does not expect, any losses from counterparty nonperformance on the interest rate swaps. The Company monitors counterparty risk in accordance with the provisions of FASB ASC 815. In addition, the interest rate swap agreements contain language outlining collateral-pledging requirements for each counterparty. Collateral must be posted when the market value exceeds certain threshold limits. As of June 30, 2015 , the Company pledged to the counterparty $200 of required collateral in the form of cash on deposit with a third party. The tables below identify the balance sheet category and fair values of the Company's derivative instruments designated as cash flow hedges as of June 30, 2015 and December 31, 2014 .

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 June 30, 2015 and December 31, 2014 . June 30, 2015 December 31, 2014 Commitments to extend credit $ 463,723 $ 441,124 Standby letters of credit 5,876 14,595 $ 469,599 $ 455,719 West Bank previously had executed Mortgage Partnership Finance (MPF) Master Commitments (Commitments) with the FHLB of Des Moines to deliver 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. West Bank receives credit enhancement fees from the FHLB for providing this guarantee and continuing to assist with managing the credit risk of the MPF Program mortgage loans. The term of the most recent Commitment was through January 16, 2015 and was not renewed. At June 30, 2015 , the liability represented by the present value of the credit enhancement fees less any expected losses in the mortgages delivered under the Commitments was approximately $412 . Contractual commitments : The Company has remaining commitments to invest in four qualified affordable housing projects totaling $4,444 as of June 30, 2015 . Contingencies : On September 29, 2010, West Bank was sued in a class action lawsuit that, as amended, asserts nonsufficient funds fees charged by West Bank to Iowa resident customers on debit card transactions are usurious under the Iowa Consumer Credit Code, rather than allowable fees, and that the sequence in which West Bank formerly posted debit card transactions for payment violated various alleged duties of good faith and ordinary care. Plaintiffs are seeking alternative remedies that include injunctive relief, damages (including treble damages), punitive damages, refund of fees and attorney fees. The case is currently being brought by Darla and Jason T. Legg, on behalf of themselves and all others similarly situated, in the Iowa District Court for Polk County, Iowa. West Bank believes it has substantial defenses and is vigorously defending the action. The trial court entered orders on preliminary motions on March 4, 2014. It dismissed one of the plaintiffs’ claims and found that factual disputes precluded summary judgment in West Bank’s favor on the remaining claims. In addition, the court certified two classes for further proceedings. West Bank appealed the adverse rulings to the Iowa Supreme Court. The Iowa Supreme Court has indicated that the appeal will be heard during the 2015-2016 court term. The appeals have not yet been assigned a date for oral argument. The amount of potential loss, if any, cannot be reasonably estimated now because of the unresolved legal issues and because, among other things, the multiple alternative claims involve different time periods, burdens of proof, defenses and potential remedies. Except as described above, neither the Company nor West Bank is a party, and no property of these entities is subject, to any other material pending legal proceedings, other than ordinary routine litigation incidental to West Bank's business. The Company does not know of any proceeding contemplated by a governmental authority against the Company or West Bank.

Fair Value Measurements [Abstract]
Fair Value Measurements [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 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 six months ended June 30, 2015 . The following is a description of valuation methodologies used for 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. 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. 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. Level 1 securities include certain corporate bonds and preferred stocks, and would include U.S. Treasuries, if any were held. Level 2 securities include U.S. government and agency securities, collateralized mortgage obligations, mortgage-backed securities, state and political subdivision securities, and a trust preferred security. The Company currently holds no investment securities classified as Level 3. Generally, management obtains the fair value of investment securities at the end of each reporting period via a third party pricing service. Management, with the assistance of an independent investment advisory firm, reviewed the valuation process used by the third party and believes that process was valid. On a quarterly basis, management corroborates the fair values of investment securities by obtaining pricing from an independent investment advisory firm and compares the two sets of fair values. Any significant variances are reviewed and investigated. In addition, the Company has instituted a practice of further testing the fair values of a sample of securities. For that sample, the prices are further validated by management, with assistance from an independent investment advisory firm, 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 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 position is classified within Level 2 of the fair value hierarchy and is 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 are 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. 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. The following tables present the balances of assets and liabilities measured at fair value on a recurring basis by level as of June 30, 2015 and December 31, 2014 . June 30, 2015 Description Total Level 1 Level 2 Level 3 Financial assets: Investment securities available for sale: U.S. government agencies and corporations $ 2,750 $ — $ 2,750 $ — State and political subdivisions 55,043 — 55,043 — Collateralized mortgage obligations 116,501 — 116,501 — Mortgage-backed securities 59,737 — 59,737 — Trust preferred security 1,040 — 1,040 — Corporate notes and equity securities 10,130 9,830 300 — Financial liabilities: Derivative instruments, interest rate swaps $ (381 ) $ — $ (381 ) $ — December 31, 2014 Description Total Level 1 Level 2 Level 3 Financial assets: Investment securities available for sale: U.S. government agencies and corporations $ 12,820 $ — $ 12,820 $ — State and political subdivisions 52,359 — 52,359 — Collateralized mortgage obligations 125,870 — 125,870 — Mortgage-backed securities 66,153 — 66,153 — Trust preferred security 918 — 918 — Corporate notes and equity securities 14,670 14,370 300 — Financial liabilities: Derivative instruments, interest rate swaps $ (261 ) $ — $ (261 ) $ — The following table presents changes in investment securities available for sale with significant unobservable inputs (Level 3) for the three and six months ended June 30, 2015 and 2014 .

That is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following tables present those assets carried on the balance sheet by caption and by level within the valuation hierarchy as of June 30, 2015 and December 31, 2014 . June 30, 2015 Description Total Level 1 Level 2 Level 3 Impaired loans $ 474 $ — $ — $ 474 Other real estate owned 2,235 — — 2,235 December 31, 2014 Description Total Level 1 Level 2 Level 3 Impaired loans $ 1,266 $ — $ — $ 1,266 Other real estate owned 2,235 — — 2,235 Loans in the previous tables consist of impaired loans for which a fair value adjustment was recorded. Impaired loans 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. Collateral may be real estate or business assets such as equipment, inventory or accounts receivable. Fair value is determined by management evaluations or independent appraisals. Appraised or reported values may be discounted based on management's opinions concerning market developments or the client's business. Other real estate owned in the tables above consists of property acquired through foreclosures and loan settlements. Property acquired is carried at fair value of the property less estimated disposal costs. Fair value of other real estate owned is determined by management by obtaining appraisals or other market value information at the time of acquisition, is updated at least annually, and may be discounted. The following tables present additional quantitative information about assets measured at fair value on a nonrecurring basis for which the Company has utilized Level 3 inputs to determine fair value as of June 30, 2015 and December 31, 2014 . June 30, 2015 Fair Value Valuation Technique Unobservable Input Range (Average) Impaired loans $ 474 Evaluation of collateral Estimation of value NM* Other real estate owned 2,235 Appraisal Appraisal adjustment 0.0% - 25.0% (25.0%) December 31, 2014 Fair Value Valuation Technique Unobservable Input Range (Average) Impaired loans $ 1,266 Evaluation of collateral Estimation of value NM* Other real estate owned 2,235 Appraisal Appraisal adjustment 0.0% - 25.0% (25.0%) * Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. 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 included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful. 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 methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or nonrecurring basis are discussed above. The methodologies for other financial assets and financial liabilities are discussed below. Cash and due from banks : The carrying amount approximates fair value. Federal funds sold : The carrying amount approximates fair value. Investment securities held to maturity : The fair values of these securities, which are all state and political subdivisions, are determined by the same method described previously for investment securities available for sale. FHLB stock : The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share. Loans : The fair values of fixed rate loans are estimated using discounted cash flow analysis based on observable market interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The carrying values of variable rate loans approximate their fair values. Deposits : The carrying amounts for demand and savings deposits, which represent the amounts payable on demand, approximate their fair values. The fair values for certificates of deposit are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on certificates with similar terms. Accrued interest receivable and payable : The fair values of both accrued interest receivable and payable approximate their carrying amounts. Borrowings : The carrying amounts of federal funds purchased, short-term borrowings and variable rate long-term borrowings approximate their fair values. Fair values of fixed rate FHLB advances, subordinated notes and other long-term borrowings are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered with similar terms. Commitments to extend credit and standby letters of credit : The approximate fair values of commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and creditworthiness of the counterparties. The following table presents the carrying amounts and approximate fair values of financial assets and liabilities as of June 30, 2015 and December 31, 2014 .

Basis of Presentation [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. 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, 2014 . In the opinion of management, the accompanying consolidated financial statements contain all adjustments necessary to fairly present the financial position as of June 30, 2015 and December 31, 2014 , and net income and comprehensive income for the three and six months ended June 30, 2015 and 2014 , and cash flows for the six months ended June 30, 2015 and 2014 . 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 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 and other than temporary impairment (OTTI) 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 wholly-owned subsidiary WB Funding Corporation (which owns an interest in a limited liability company). West Bank's 99.99 percent owned subsidiary ICD IV, LLC (a community development entity) was liquidated during the third quarter of 2014 because the underlying loan matured. All significant intercompany transactions and balances have been eliminated in consolidation.

New Accounting Pronouncements, Policy [Policy Text Block]	Current accounting developments: In January 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-04, Receivables—Troubled Debt Restructuring by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The update clarifies when an in substance foreclosure occurs, that is, when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan. This is the point when the consumer mortgage loan should be derecognized and the real property recognized. For public companies, this update was effective for interim and annual periods beginning after December 31, 2014. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 660): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs—Contracts with Customers (Subtopic 340-40) . The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. For public companies, this update was originally effective for interim and annual periods beginning after December 15, 2016. In July 2015, the FASB voted to delay the effective date of this ASU by one year. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update simplifies the presentation of debt issuance costs by requiring that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2015, and is to be applied retrospectively. Early adoption is permitted. The Company has determined that this guidance will not have a material impact 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.
Loans and Leases Receivable, Origination Fees, Discounts or Premiums, and Direct Costs to Acquire Loans Policy [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 those outstanding loan balances. 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.
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	A loan is classified as a troubled debt restructured (TDR) loan when the Company concludes that a borrower is experiencing financial difficulties and a concession was granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden on 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 past due 90 days 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 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. Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. 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. 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 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 six months ended June 30, 2015 . The following is a description of valuation methodologies used for 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. 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. 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. Level 1 securities include certain corporate bonds and preferred stocks, and would include U.S. Treasuries, if any were held. Level 2 securities include U.S. government and agency securities, collateralized mortgage obligations, mortgage-backed securities, state and political subdivision securities, and a trust preferred security. The Company currently holds no investment securities classified as Level 3. Generally, management obtains the fair value of investment securities at the end of each reporting period via a third party pricing service. Management, with the assistance of an independent investment advisory firm, reviewed the valuation process used by the third party and believes that process was valid. On a quarterly basis, management corroborates the fair values of investment securities by obtaining pricing from an independent investment advisory firm and compares the two sets of fair values. Any significant variances are reviewed and investigated. In addition, the Company has instituted a practice of further testing the fair values of a sample of securities. For that sample, the prices are further validated by management, with assistance from an independent investment advisory firm, 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 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 position is classified within Level 2 of the fair value hierarchy and is 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 are 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. 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.
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. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or nonrecurring basis are discussed above. The methodologies for other financial assets and financial liabilities are discussed below. Cash and due from banks : The carrying amount approximates fair value. Federal funds sold : The carrying amount approximates fair value. Investment securities held to maturity : The fair values of these securities, which are all state and political subdivisions, are determined by the same method described previously for investment securities available for sale. FHLB stock : The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share. Loans : The fair values of fixed rate loans are estimated using discounted cash flow analysis based on observable market interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The carrying values of variable rate loans approximate their fair values. Deposits : The carrying amounts for demand and savings deposits, which represent the amounts payable on demand, approximate their fair values. The fair values for certificates of deposit are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on certificates with similar terms. Accrued interest receivable and payable : The fair values of both accrued interest receivable and payable approximate their carrying amounts. Borrowings : The carrying amounts of federal funds purchased, short-term borrowings and variable rate long-term borrowings approximate their fair values. Fair values of fixed rate FHLB advances, subordinated notes and other long-term borrowings are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered with similar terms. Commitments to extend credit and standby letters of credit : The approximate fair values of commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and creditworthiness of the counterparties.
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.
