Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Centrue Financial Corporation is a bank holding company organized under the laws of the State of Delaware. When we use the terms “Centrue,” the “Company,” “we,” “us,” and “our,” we mean Centrue Financial Corporation, a Delaware corporation, and its consolidated subsidiary. When we use the term the “Bank,” we are referring to our wholly owned banking subsidiary, Centrue Bank. The Company and the Bank provide a full range of banking services to individual and corporate customers located in markets extending from the far western and southern suburbs of the Chicago metropolitan area across Central Illinois down to the metropolitan St. Louis area. These services include demand, time, and savings deposits; business and consumer lending; and mortgage banking. The Company is subject to competition from other financial institutions and nonfinancial institutions providing financial services. Additionally, the Company and the Bank are subject to regulations of certain regulatory agencies and undergo periodic examinations by those regulatory agencies. Basis of presentation The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles (“GAAP”) and general practice within the banking industry. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities and other-than-temporary impairment of securities, the determination of the allowance for loan losses and valuation of other real estate owned. For further information with respect to significant accounting policies followed by the Company in the preparation of its consolidated financial statements, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 . The consolidated financial statements include the accounts of the Company and Centrue Bank. Intercompany balances and transactions have been eliminated in consolidation and certain 2015 amounts have been reclassified to conform to the 2016 presentation. The annualized results of operations during the three months ended March 31, 2016 are not necessarily indicative of the results expected for the year ending December 31, 2016 . All financial information in the following tables is in thousands (000s), except share and per share data. In the opinion of management, all normal and recurring adjustments which are necessary to fairly present the results for the interim periods presented have been included. Reverse Stock Split Common shares and per share amounts for all periods shown have been restated to reflect the impact of the 1: 30 reverse stock split the Company completed effective May 29, 2015. Capital Event On March 31, 2015, the Company completed the issuance of $76.0 million of new common stock in a private placement offering, $68.2 million of net proceeds after issuance and registration costs of $7.8 million . A total of 6.3 million shares were sold in the offering at a price of $12.00 per share. In conjunction with the stock offering the Company used the proceeds in part to pay $4.9 million in accrued but unpaid interest on its subordinated debentures, redeemed all $32.7 million of Series C Preferred Stock for $19.0 million , settled $10.3 million in notes payable with a financial institution for $8.5 million and made a $36.0 million capital contribution into Centrue Bank. The remaining proceeds have been and will be used for general corporate purposes. Recent Accounting Pronouncements In March 2016, the FASB issued an update (ASU No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting.) The guidance in this update affects any entity that issues share-based payment awards to its employees and is intended to simplify several aspects of the accounting for share-based payment awards including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. Management is currently evaluating the impact on the consolidated financial statements and related disclosures. In February 2016, the FASB issued an update (ASU No. 2016-02, Leases) creating FASB Topic 842, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring more disclosures related to leasing transactions. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact on the consolidated financial statements and related disclosures. In January 2016, the FASB issued an update, ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance in this update requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Management is currently determining the impact of this new guidance on the consolidated financial statements. In May 2014, the FASB issued an update (ASU No. 2014-09, Revenue from Contracts with Customers) creating FASB Topic 606, Revenue from Contracts with Customers. The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The amendments in this update will become effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. Management is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

Earnings Per Share	Earnings Per Share A reconciliation of the numerators and denominators for earnings per common share computations for the three months ended March 31, 2016 and 2015 is presented below (shares in thousands). Common shares, options, and per share amounts for all periods shown have been restated to reflect the impact of the one for thirty reverse stock split the Company completed effective May 29, 2015. Options to purchase 1,992 and 4,982 shares of common stock were outstanding for March 31, 2016 and 2015 , respectively; but were not included in the computation of diluted earnings per share because the exercise price was greater than the average market price and, therefore, were anti-dilutive.

Internal risk ratings of 0 to 5 are considered pass credits, a risk rating of a 6 is special mention, a risk rating of a 7 is substandard, and a risk rating of an 8 is doubtful. Loans classified as pass credits have no material weaknesses and are performing as agreed. Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Specific reserves were immaterial at March 31, 2016 and December 31, 2015 . At March 31, 2016 nonaccrual TDR loans were $0.23 million and $0.24 million at December 31, 2015 . There were no TDRs on accrual at March 31, 2016 and December 31, 2015 . The Company had no commitments to lend additional amounts to a customer with an outstanding loan that is classified as TDR as of March 31, 2016 and December 31, 2015 . Over the course of a period, the terms of certain loans may be modified as troubled debt restructurings. The modification of the terms of such loans may include one or a combination of the following: a reduction of the stated interest rate of the loan to a below market rate or the payment modification to interest only. A modification involving a reduction of the stated interest rate of the loan would be for periods ranging from 6 months to 16 months . During the three months ended March 31, 2016 , there were no loans modified as troubled debt restructurings compared to the same three month period ended March 31, 2015 when there was one Senior lien 1-4 family residential loan modified as troubled debt restructurings with a pre-modification and post-modification recorded investment of $0.03 million . The troubled debt restructurings described above did not have a material impact to the allowance for loan losses and did not result in any additional charge-offs during the three months ended March 31, 2015 . A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. In the three months ended March 31, 2016 and the three months ended March 31, 2015 there were no loans modified as troubled debt restructurings for which there was a payment default within twelve months following the modification. The Company evaluates loan modifications to determine if the modification constitutes a troubled debt restructure. A loan modification constitutes a troubled debt restructure if the borrower is experiencing financial difficulty and the Company grants a concession it would not otherwise consider. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its loans with the Company’s debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting guidelines. TDRs are separately identified for impairment disclosures. If a loan is considered to be collateral dependent loan, the TDR is reported, net, at the fair value of the collateral.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company measures, monitors, and discloses certain of its assets and liabilities on a fair value basis. 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 at the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Fair value guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value into three broad levels based on the reliability of the input assumptions. The hierarchy gives the highest priority to level 1 measurements and the lowest priority to level 3 measurements and the categorization of where an asset or liability falls within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy are defined as follows: Level 1 - Unadjusted quoted prices for identical assets or liabilities traded in active markets. Level 2 - Observable inputs other than level 1 prices, such as quoted prices for similar instruments; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Securities Available for Sale Securities. The fair value of securities available for sale is determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). If the securities could not be priced using quoted market prices, observable market activity or comparable trades, the financial market was considered not active and the assets were classified as Level 3. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table summarizes, by measurement hierarchy, the various assets and liabilities of the Company that are measured at fair value on a recurring basis: Carrying Amount Quoted Prices in Active Markets For Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2016 U.S. government agencies $ 9,663 $ — $ 9,663 $ — State and political subdivisions 13,095 — 8,077 5,018 U.S. government agency residential mortgage-backed securities 126,899 — 126,899 — Collateralized mortgage obligations: Agency 17,226 — 17,226 — Equities 2,899 — 2,899 — Available-for-sale securities $ 169,782 $ — $ 164,764 $ 5,018 Carrying Amount Quoted Prices in Active Markets For Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2015 U.S. government agencies $ 14,607 $ — $ 14,607 $ — State and political subdivisions 10,181 — 5,160 5,021 U.S. government agency residential mortgage-backed securities 126,029 — 126,029 — Collateralized mortgage obligations: Agency 17,833 — 17,833 — Equities 2,790 — 2,790 — Available-for-sale securities $ 171,440 $ — $ 166,419 $ 5,021 There were no transfers between Level 1 and Level 2 during the first three months of 2016 and all of 2015 . Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs The following table reconciles the beginning and ending balances of the assets of the Company that are measured at fair value on a recurring basis using significant unobservable inputs. Securities Available for Sale 2016 Beginning balance, January 1 $ 5,021 Transfers into Level 3 — Total gains or losses (realized/unrealized) included in earnings Sales — Security impairment — Payment received — Other changes in fair value (3 ) Included in other comprehensive income — Ending Balance, March 31 $ 5,018 For the period ended March 31, 2016 , the Company had $5.0 million of local school district bonds that are measured at fair value on a recurring basis using unobservable inputs. The fair value was obtained from third party sources, and was not adjusted by management. Assets Measured at Fair Value on a Non-Recurring Basis The following table summarizes, by measurement hierarchy, financial assets of the Company that are measured at fair value on a non-recurring basis. Carrying Amount Quoted Prices in Active Markets For Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2016 Impaired loans Commercial Closed-end $ 36 $ — $ — $ 36 Line of credit — — — — 1-4 family residential Senior lien 732 — — 732 OREO property CRE - construction, land & development 873 — — 873 CRE - all other Owner occupied 450 — — 450 Non-owner occupied 130 — — 130 1-4 family residential Senior lien 149 — — 149 Carrying Amount Quoted Prices in Active Markets For Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2015 Impaired loans 1-4 family residential Senior lien $ 572 $ — $ — $ 572 OREO property CRE - construction, land & development 1,140 — — 1,140 CRE - all other Non-owner occupied 468 — — 468 1-4 family residential Senior lien 131 — — 131 At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value generally receive specific allocations of the allowance for loan losses. For collateral dependent loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Impaired loans carried at fair value had a carrying amount of $0.8 million at March 31, 2016 , with $0.2 million specific loan loss allocation and $0.01 million effect on the provision for loan losses for the three month period. In 2015 impaired loans carried at fair value had a carrying amount of $0.6 million with a specific loan loss allocation of $0.3 million during 2015 , resulting in an additional provision for loan losses of $0.1 million for the year ended December 31, 2015 . The majority of the Bank's impaired loans are collateralized by real estate. Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Any write-downs in the carrying value of a property at the time of acquisition are charged against the allowance for loan losses. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Management periodically reviews the carrying value of other real estate owned. Any write-downs of the properties subsequent to acquisition, as well as gains or losses on disposition and income or expense from the operations of other real estate owned, are recognized in operating results in the period they are realized. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. OREO properties measured at fair value, less costs to sell, had a net carrying amount of $1.6 million which is made up of the outstanding balance of $3.1 million , net of a valuation allowance of $1.5 million at March 31, 2016 . This compares to 2015 when OREO properties with an outstanding balance of $2.9 million was written down to a fair value of $1.7 million .

In addition, nonfinancial instruments typically not recognized in financial statements nevertheless may have value but are not included in the above disclosures. These include, among other items, the estimated earning potential of core deposit accounts, the earnings potential of loan servicing rights, the earnings potential of the trust operations, customer goodwill and similar items. The methods and assumptions, not previously presented, used to estimate fair values are described as follows: (a) Cash and Cash Equivalents The carrying amounts of cash and short-term instruments approximate fair values and are classified as either Level 1 or Level 2. As of March 31, 2016 and December 31, 2015 ; $23.4 million and $27.7 million was classified as Level 1. (b) Restricted securities It is not practical to determine the fair value of restricted securities due to the restrictions placed on its transferability. (c) Loans Fair values of loans, excluding loans held for sale, are estimated as follows: Fair values for loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification. (d) Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 2. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (e) Short-term Borrowings The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, approximate their fair values resulting in a Level 2 classification. (f) Other Borrowings The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. The fair values of the Company’s Subordinated Debentures are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification. (g) Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 2 or Level 3 classification which is consistent with the underlying asset/liability they are associated with. (h) Off-balance Sheet Instruments Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments is not material.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In accordance with current income tax accounting guidance, the Company assessed whether a valuation allowance should be established against their deferred tax assets (DTAs) based on consideration of all available evidence using a “more likely than not” standard. The most significant portions of the deductible temporary differences relate to (1) net operating loss carryforwards and (2) the allowance for loan losses. In assessing the need for a valuation allowance, both the positive and negative evidence about the realization of DTAs were evaluated. The ultimate realization of DTAs is based on the Company’s ability to carryback net operating losses to prior tax periods, tax planning strategies that are prudent and feasible, the reversal of deductible temporary differences that can be offset by taxable temporary differences and future taxable income. After evaluating all of the factors previously summarized and considering the weight of the positive evidence compared to the negative evidence, the Company has determined that no valuation allowance was necessary as of March 31, 2016 and December 31, 2015 . Below is a summary of items included in the deferred tax inventory as of March 31, 2016 and December 31, 2015 : March 31, 2016 December 31, 2015 Deferred tax assets Allowance for loan losses $ 3,490 $ 3,342 Deferred compensation, other 196 74 Stock based expense 87 87 Net operating loss carryforwards 33,427 34,180 Securities available-for-sale — 405 Deferred tax credits 854 823 OREO valuation allowance 1,032 1,059 Other 249 255 Total deferred tax assets 39,335 40,225 Deferred tax liabilities Depreciation $ (67 ) $ (58 ) Adjustments arising from acquisitions (55 ) (146 ) Mortgage servicing rights (813 ) (828 ) Securities available-for-sale (46 ) — Federal Home Loan Bank dividend received in stock (450 ) (450 ) Deferred loan fees & costs (399 ) (399 ) Prepaid expenses (163 ) (164 ) Total deferred tax liabilities (1,993 ) (2,045 ) Valuation allowance — — Net deferred tax assets $ 37,342 $ 38,180

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share Based Compensation	Share Based Compensation In April 2003, the Company adopted the 2003 Option Plan. Under the 2003 Option Plan, as amended on April 24, 2007, nonqualified options, incentive stock options, restricted stock and/or stock appreciation rights may be granted to employees and outside directors of the Company and its subsidiaries to purchase the Company's common stock at an exercise price to be determined by the executive and compensation committee. Pursuant to the 2003 Option Plan, 19,000 shares of the Company's unissued common stock had been reserved and were available for issuance upon the exercise of options and rights granted under the 2003 Option Plan. The granted options have an exercise period of seven to ten years from the date of grant. In May 2015, the Company adopted the 2015 Stock Compensation Plan. Under the 2015 Stock Compensation Plan nonqualified options, incentive stock options, restricted stock and/or stock appreciation rights may be granted to employees and outside directors of the Company and its subsidiaries to purchase the Company's common stock at an exercise price to be determined by the compensation committee. A total of 430,000 shares have been made available under the 2015 Stock Compensation Plan. There are currently 389,557 shares available to grant. No options or restricted stock were granted or exercised for the three months ended March 31, 2016 . There were 40,443 shares of restricted stock granted for the year ended December 31, 2015 . There was no compensation cost charged against income for the stock options portion of the equity incentive plans for the three months ended March 31, 2016 and for the year ended December 31, 2015 . There was no compensation cost charged against income for the restricted stock portion of the equity incentive plan for the three months ended March 31, 2016 and $0.5 million charged for the year ended December 31, 2015 . The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected volatilities are based on historical volatilities of the Company’s common stock prior to its deregistration. The Company uses historical data to estimate option exercise and post-vesting termination behavior. (Employee and management options are tracked separately.) The expected term of options granted is based on historical data and represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no options granted for the three months ended March 31, 2016 and the year ended December 31, 2015 . A status summary of the option plan as of March 31, 2016 and changes during the period ended on that date are presented below: Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1, 2016 3,156 $ 338.72 Granted — — Exercised — — Forfeited (1,164 ) 289.20 Outstanding at end of period 1,992 $ 367.65 0.3 years $ — Vested or expected to vest 1,992 $ 367.65 0.3 years $ — Options exercisable at period end 1,992 $ 367.65 0.3 years $ — Options outstanding at March 31, 2016 and year-end 2015 were as follows: Outstanding Exercisable Range of Exercise Prices Number Weighted Average Remaining Contractual Life Number Weighted Average Exercise Price March 31, 2016 $157.20 - $390.00 996 0.1 years 996 $ 157.20 390.01 - 578.10 996 0.6 years 996 578.10 1,992 0.3 years 1,992 $ 367.65 December 31, 2015: $157.20 - $390.00 2,160 0.2 years 2,160 $ 228.33 390.01 - 578.10 996 0.9 years 996 578.10 3,156 0.4 years 3,156 $ 338.72 As of March 31, 2016 and December 31, 2015 , there was no unrecognized compensation cost related to non-vested stock options granted under the 2003 Option Plan.

Regulatory Matters

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters The Company and Centrue Bank are subject to regulatory capital requirements administered by federal and state banking agencies that involve the quantitative measure of their assets, liabilities, and certain off-balance-sheet items, as calculated under regulatory accounting practices. Quantitative measures established by regulations to ensure capital adequacy require the Company and Centrue Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 capital and Common Equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined in the regulations), and, for the Bank, Tier 1 capital (as defined in the regulations) to average assets (as defined in the regulations). Failure to meet minimum capital requirements may cause regulatory bodies to initiate certain discretionary and/or mandatory actions that, if undertaken, may have a direct material effect on our financial statements. The Company, as a financial holding company, is required to be “adequately capitalized” in the capital categories shown in the table below. As of March 31, 2016 , Centrue Bank met all capital adequacy requirements to which they were subject, including the guidelines to be considered “well capitalized.” On July 2, 2013, the Federal Reserve Board and the FDIC approved rules that implement the “Basel III” regulatory capital reforms, as well as certain changes required by the Dodd-Frank Act. The rules include a common equity Tier 1 capital ratio and conservation buffer of 2.5% of risk-weighted assets, which is in addition to the Tier 1 and Tier 2 risk-based capital requirements. The capital conservation buffer will be phased in over four years beginning on January 1, 2016, with a maximum buffer of 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. Failure to maintain the required capital conservation buffer will result in limitations on capital distributions and on discretionary bonuses to executive officers. Capital ratios shown for March 31, 2016 are in excess of the Basel III 2016 phase-in level for the capital conservation buffer. On February 16, 2016 the Company received a formal order terminating the written agreement between the Company, the Bank, and the Federal Reserve Bank of Chicago and the Illinois Department of Financial and Professional Regulation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles (“GAAP”) and general practice within the banking industry. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities and other-than-temporary impairment of securities, the determination of the allowance for loan losses and valuation of other real estate owned. For further information with respect to significant accounting policies followed by the Company in the preparation of its consolidated financial statements, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 . The consolidated financial statements include the accounts of the Company and Centrue Bank. Intercompany balances and transactions have been eliminated in consolidation and certain 2015 amounts have been reclassified to conform to the 2016 presentation. The annualized results of operations during the three months ended March 31, 2016 are not necessarily indicative of the results expected for the year ending December 31, 2016 . All financial information in the following tables is in thousands (000s), except share and per share data. In the opinion of management, all normal and recurring adjustments which are necessary to fairly present the results for the interim periods presented have been included.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the FASB issued an update (ASU No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting.) The guidance in this update affects any entity that issues share-based payment awards to its employees and is intended to simplify several aspects of the accounting for share-based payment awards including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. Management is currently evaluating the impact on the consolidated financial statements and related disclosures. In February 2016, the FASB issued an update (ASU No. 2016-02, Leases) creating FASB Topic 842, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring more disclosures related to leasing transactions. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact on the consolidated financial statements and related disclosures. In January 2016, the FASB issued an update, ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance in this update requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Management is currently determining the impact of this new guidance on the consolidated financial statements. In May 2014, the FASB issued an update (ASU No. 2014-09, Revenue from Contracts with Customers) creating FASB Topic 606, Revenue from Contracts with Customers. The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The amendments in this update will become effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. Management is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.
