Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	1. Basis of Presentation The Unaudited Condensed Consolidated Financial Statements include the accounts of Bank Mutual Corporation (the “Company”), its wholly-owned subsidiary Bank Mutual (the “Bank”), and the Bank’s subsidiaries. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information, Rule 10-01 of Regulation S-X, and the instructions to Form 10-Q. The financial statements do not include all of the information and footnotes required by GAAP for complete financial information. However, in the opinion of management, all adjustments (consisting of normal recurring entries) necessary for a fair presentation of operations, cash flows, and financial position have been included in the accompanying financial statements. This report should be read in conjunction with the Company’s 2015 Annual Report on Form 10-K. Operating results for the three and six months ended June 30, 2016, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2016. In 2014 the Financial Accounting Standards Board (“FASB”) issued new accounting guidance related to the recognition of revenue from contracts with customers. In 2015 the FASB deferred the effective date one year from the date in the original guidance. The guidance is effective for fiscal years and interim periods beginning after December 15, 2018, which will be the first quarter of 2019 for the Company. In 2016 the FASB issued two new pronouncements to amend and clarify the original guidance with no change to the effective date. The Company’s adoption of this item is not expected to have a material impact on its results of operations or financial condition. In 2015 the FASB issued new accounting guidance relating to the consolidation of legal entities for financial reporting purposes. For public companies, the guidance is effective for periods beginning after December 15, 2015, which was the first quarter of 2016 for the Company. The Company’s adoption of this new guidance did not have a material impact on its results of operations or financial condition. In 2016 the FASB issued new accounting guidance related to certain aspects of the recognition and measurement of financial assets and liabilities. For public companies the guidance is effective for periods beginning after December 15, 2017, which will be the first quarter of 2018 for the Company. Early application of some aspects of the new guidance is also permitted, although the Company does not intend to adopt the guidance early. The Company’s eventual adoption of this new guidance is not expected to have a material impact on its results of operations or financial condition. In 2016 the FASB issued new accounting guidance related to the accounting for lease assets and liabilities. For public companies the guidance is effective for periods beginning after December 15, 2018, which will be the first quarter of 2019 for the Company. The Company’s adoption of this item is not expected to have a material impact on its results of operations or financial condition. In 2016 the FASB issued new accounting guidance related to the accounting for employee share-based compensation. For public companies the guidance is effective for periods beginning after December 15, 2016, with early adoption permitted. The Company adopted this guidance in the first quarter of 2016. The Company’s adoption of this item did not have a material impact on its results of operations or financial condition. In 2016 the FASB issued new accounting guidance related to the measurement of credit losses on financial instruments. The new guidance replaces the current methodology of measuring credit losses based on incurred losses at the balance sheet date with a methodology that measures credit losses based on the current estimate of expected credit losses. For the Company this guidance is effective for periods beginning after December 15, 2019, which will be the first quarter of 2020. Management has not yet completed the complex analysis required to determine the impact adoption of this new guidance could have on the Company’s results of operations or financial condition.

The Company does not intend to sell these securities and it is unlikely that it will be required to sell these securities before the recovery of their amortized cost. The Company believes it is probable that it will receive all future contractual cash flows related to these securities. This determination was based on management’s judgment regarding the nature of the loan collateral that supports the securities, a review of the current ratings issued on the securities by various credit rating agencies, recent trends in the fair market values of the securities and, in the case of private-label collateralized mortgage obligations (“CMOs”), a review of the actual delinquency and/or default performance of the loan collateral that supports the securities. As of June 30, 2016, and December 31, 2015, the Company had private-label CMOs, with a fair value of $ 13,696 15,725 84 237 Three Months Ended Six Months Ended 2016 2015 2016 2015 Beginning balance of unrealized OTTI related to credit losses $ 557 $ 692 $ 592 $ 789 Reductions for increase in cash flows expected to be received (35) (35) (70) (132) Ending balance of unrealized OTTI related to credit losses $ 522 $ 657 $ 522 $ 657 Adjusted cost at end of period $ 3,810 $ 4,911 $ 3,810 $ 4,911 Estimated fair value at end of period $ 4,098 $ 5,390 $ 4,098 $ 5,390 Results of operations included no gross realized gains or losses on the sale of securities during the three and six months ended June 30, 2016 or 2015.

Management considered these adjustments necessary and prudent in light of trends in net charge-offs, real estate values, economic conditions, and unemployment. The Company estimates that these changes, as well as overall changes in the balance of loans to which these factors were applied, resulted in an increase (decrease) in the total allowance for loan

“pass” or “watch” are generally current on contractual loan and principal payments and comply with other contractual loan terms. Pass loans generally have no noticeable credit deficiencies or potential weaknesses. Loans rated watch, however, will typically exhibit early signs of credit deficiencies or potential weaknesses that deserve management’s close attention. Loans rated “special mention” do not currently expose the Company to a sufficient degree of risk to warrant a lower rating, but possess clear trends in credit deficiencies or potential weaknesses that deserve management’s close attention. The allowance for loan losses on loans rated pass, watch, or special mention is typically evaluated collectively for impairment using a homogenous pool approach. This approach utilizes quantitative factors developed by management from its assessment of historical loss experience, qualitative factors, and other considerations. Loans rated “substandard” involve a distinct possibility that the Company could sustain some loss if deficiencies associated with the loan are not corrected. Loans rated “doubtful” indicate that full collection is highly questionable or improbable. The Company did not have any loans that were rated doubtful at June 30, 2016, or December 31, 2015. Loans rated substandard or doubtful that are also considered in management’s judgment to be impaired are generally analyzed individually to determine an appropriate allowance for loan loss. A loan rated “loss” is considered uncollectible, even if a partial recovery could be expected in the future. The Company generally charges off loans that are rated as a loss. As such, the Company did not have any loans that were rated loss at June 30, 2016, or December 31, 2015.

Loan modifications that result in insignificant delays in the receipt of payments (generally six months or less) are not considered TDRs under the Company’s TDR policy. TDRs are relatively insignificant and/or infrequent in the Company and generally consist of loans placed in interest-only status for a short period of time or payment forbearance for greater than six months. As of June 30, 2016, and December 31, 2015, TDRs were $ 8,264 8,704 2,900 2,558

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	8. Regulatory Capital Requirements The Company and Bank are subject to various regulatory capital requirements administered by federal banking agencies and as defined in applicable regulations. Failure to meet minimum capital requirements can initiate certain mandatory actions and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	10. Employee Benefit Plans The Company has a discretionary, defined contribution savings plan (the “Savings Plan”). The Savings Plan is qualified under Sections 401 and 401(k) of the Internal Revenue Code and provides employees meeting certain minimum age and service requirements the ability to make contributions to the Savings Plan on a pretax basis. The Company then matches a percentage of the employee’s contributions. Matching contributions expensed by the Company were $ 210 214 The Company also has a qualified defined benefit pension plan covering employees meeting certain minimum age and service requirements and a supplemental defined benefit pension plan for certain eligible employees. The supplemental pension plan is funded through a "rabbi trust" arrangement. The benefits under these plans are generally based on the employee’s years of service and average annual wages, as defined in the plan. The Company’s funding policy is to contribute annually the amount necessary to satisfy the requirements of the Employee Retirement Income Security Act of 1974. In prior periods the Company closed the qualified defined benefit pension plan to new participants and froze the benefits of all existing participants. These changes resulted in the future benefits under the Company’s supplemental defined benefit pension plan also being effectively frozen.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	11. Stock-Based Benefit Plans In 2004 the Company’s shareholders approved the 2004 Stock Incentive Plan (the “2004 Plan”). Options and restricted stock granted under the 2004 Plan vested over five years and options had expiration terms of ten years. No further awards may be made under the 2004 Plan. In 2014 the Company’s shareholders approved the 2014 Incentive Compensation Plan (the “2014 Plan”), which provides for the award of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, and cash awards. Stock-related awards under the 2014 Plan vest over a period of three or more years and, if applicable, have a maximum term of ten years. The number of shares of common stock of the Company that may be issued under the 2014 Plan is limited to 3,000,000 2,497,600 Restricted stock grants are amortized to compensation expense as the Company’s employees and directors become vested in the granted shares.

This model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. However, the Company's stock options have characteristics significantly different from traded options and changes in the subjective input assumptions can materially affect the fair value estimate. Option valuation models such as Black-Scholes require the input of highly subjective assumptions including the expected stock price volatility, which is computed using ten years of actual price activity in the Company’s stock. The Company uses historical data of employee behavior as a basis to estimate the expected life of the options, as well as forfeitures due to employee terminations. The Company also uses its actual dividend yield at the time of the grant, as well as actual U.S. Treasury yields in effect at the time of the grant to estimate the risk-free rate. The following weighted-average assumptions were used to value 56,300 1.80 2.74 31 7.5 2.28 37,000 1.75 2.40 34 7.5 2.09

Fair Value Disclosures [Abstract]
Financial Instruments with Off-Balance Sheet Risk and Derivative Financial Instruments [Text Block]	12. Financial Instruments with Off-Balance Sheet Risk and Derivative Financial Instruments 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 consist of commitments to extend credit and involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the Consolidated Statements of Financial Condition. The contract amounts reflect the extent of involvement the Company has in particular classes of financial instruments and also represents the Company’s maximum exposure to credit loss. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and generally require payment of a fee. As some commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates the collateral needed and creditworthiness of each customer on a case by case basis. The Company generally extends credit only on a secured basis. Collateral obtained varies, but consists principally of one- to four-family residences.

The Company uses interest rate lock commitments (“IRLCs”) and forward commitments to sell loans to manage interest rate risk associated with its loan sales activities, both of which are considered to be free-standing derivative financial instruments under GAAP. Changes in the fair value of the derivative instruments are recognized currently through earnings. During the three months ended June 30, 2016 and 2015, net unrealized gains (losses) of $ (42) 170 36 206 96 16 137 (80) The Company enters into interest rate swap arrangements to manage the interest rate risk exposure associated with specific commercial loan relationships at the time such loans are originated. These interest rate swaps, as well as the embedded derivatives associated with certain of its commercial loan relationships, are free-standing derivative instruments under GAAP. As such, changes in the fair value of these derivative instruments are recognized currently through earnings. During the three months ended June 30, 2016 and 2015, net unrealized gains of $ 85 205 85 205 453 55 The Company also enters into interest rate swap arrangements to manage the interest rate risk exposure associated with certain forecasted borrowings from the FHLB of Chicago. These interest rate swaps have been designated as forecasted transaction cash flow hedges by management (refer to Note 7, “Borrowings”). As such, the effective portion of the change in the fair value of these derivatives is recorded in other comprehensive income and the ineffective portion was recorded in interest expense.

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments [Text Block]	13. Fair Value Measurements 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 at the measurement date (exit price). The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. The Company primarily applies the market approach for recurring value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value measurements based on the observability of those inputs. Accounting guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1), the next highest priority is given to prices based on models, methodologies, and/or management judgments that rely on direct or indirect observable inputs (Level 2), and the lowest priority to prices derived from models, methodologies, and/or management judgments that rely on significant unobservable inputs (Level 3). There were no transfers of assets or liabilities between categories of the fair value hierarchy during the six months ended June 30, 2016. The methods and assumptions used by the Company in estimating the fair value of its financial instruments, whether or not such fair values are recognized in the consolidated financial statements, are summarized below: Cash and Cash Equivalents Mortgage-Related Securities Available-for-Sale and Held-to-Maturity Loans Receivable Mortgage Servicing Rights Weighted- Range Loan size $ 116 $1-$417 Contractual interest rate 3.72 % 2.50%-7.10% Constant prepayment rate (“CPR”) 13.12 % 2.56%-24.19% Remaining maturity in months 218 2-480 Servicing fee 0.25 % – Annual servicing cost per loan (not in thousands) $ 60 – Annual ancillary income per loan (not in thousands) $ 30 – Discount rate 9.17 % 9.13%-10.88% MSR pools with an amortized cost basis greater than fair value are carried at fair value in the Company’s financial statements. There were no pools determined to be impaired at June 30, 2016, or December 31, 2015. Accordingly, the Company had no valuation allowance as of June 30, 2016, or December 31, 2015.
