Accounting Policies [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) is a bank holding company whose subsidiary is Hanmi Bank (the “Bank”). Our primary operations are related to traditional banking activities, including the acceptance of deposits and the lending and investing of money through the operation of the Bank. On May 21, 2018, the Company announced the signing of a definitive agreement to acquire SWNB Bancorp, Inc. (“SWNB”), a privately-held bank holding company for Southwestern National Bank, headquartered in Houston, Texas. With total assets of approximately $411 million , SWNB has six retail banking branches located in Houston, Dallas and Austin, Texas. The aggregate consideration for this transaction is estimated at $76.7 million based on the agreement as of the announcement date and the transaction is expected to close late in the third quarter of 2018. The Board of Directors of the Company and SWNB have approved the transaction. The directors and executive officers of SWNB have also entered into an agreement with the Company pursuant to which they have agreed to vote their shares of SWNB common stock in favor the transaction. Closing of the transaction is contingent upon approval by SWNB's shareholders as well as customary regulatory approvals. In management’s opinion, the accompanying unaudited consolidated financial statements of Hanmi Financial and its subsidiaries reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended June 30, 2018 , but are not necessarily indicative of the results that will be reported for the entire year or any other interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The aforementioned unaudited consolidated financial statements are prepared in conformity with GAAP and in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The interim information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “ 2017 Annual Report on Form 10-K”). The preparation of interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Material estimates subject to change include, among other items, the determination of allowance for loan and lease losses and various other assets and liabilities measured at fair value. Actual results could differ from those estimates. Descriptions of our significant accounting policies are included in Note 1 - Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements in our 2017 Annual Report on Form 10-K. Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) and ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). Summaries of ASU 2016-01 and 2018-02 and the impact of their adoption are included in Notes 2 and 5 to the Consolidated Financial Statements, respectively. In addition to other provisions, ASU 2016-01 requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Beginning with the quarter ended March 31, 2018, the Company measured the fair value of certain financial instruments, included in Note 10 to the Consolidated Financial Statements, using an exit price notion. The Company also adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of January 1, 2018, as required. ASU 2014-09 replaces existing revenue recognition guidance for contracts to provide goods or services to customers and amends existing guidance related to recognition of gains and losses on the sale of certain nonfinancial assets such as real estate. See Note 14 to the Consolidated Financial Statements for the impact of the adoption of this new standard on the Company's consolidated financial statements.

These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. The Company does not intend to sell these securities and it is more likely than not that we will not be required to sell the securities before the recovery of their amortized cost basis. Interest payments have been made as scheduled, and management believes this will continue in the future and that the bonds will be repaid in full as scheduled. Therefore, in management’s opinion, all securities that have been in a continuous unrealized loss position for the past 12 months or longer as of June 30, 2018 and December 31, 2017 were not other-than-temporarily impaired, and therefore, no impairment charges as of June 30, 2018 and December 31, 2017 were warranted. Realized gains and losses on sales of securities and proceeds from sales of securities were as follows for the periods indicated: Three Months Ended Six Months Ended 2018 2017 2018 2017 (in thousands) Gross realized gains on sales of securities $ 67 $ 938 $ 67 $ 1,206 Gross realized losses on sales of securities — — (957 ) — Net realized (losses) gains on sales of securities $ 67 $ 938 $ (890 ) $ 1,206 Proceeds from sales of securities $ 9,366 $ 40,115 $ 31,325 $ 52,688 In January 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This new guidance, among other provisions, amends accounting related to the classification and measurement of investments in equity securities. We adopted this guidance, as required, in the first quarter of 2018. ASU 2016-01 requires the amounts reported in accumulated other comprehensive income for equity securities that exist as of the date of adoption previously classified as available-for-sale be reclassified to retained earnings. The Company reduced the balance of securities by $529,000 as of January 1, 2018, representing the loss related to all of our mutual fund equity securities, which resulted in a net reduction of retained earnings of $382,000 and an increase of $147,000 in net deferred tax assets based on the transition requirements of this standard. For the three months ended June 30, 2018 and 2017, there was a $67,000 and $938,000 net gain in earnings resulting from the sale of securities, respectively. Net unrealized gains of $95,000 and $430,000 related to these sold securities had previously been recorded in accumulated other comprehensive income as of the beginning of the period in 2018 and 2017, respectively. During the six months ended June 30, 2018 , there was $67,000 in gains included in earnings resulting from sale of securities which had $95,000 in previously recorded unrealized gains in accumulated other comprehensive income. Additionally, during the six months ended June 30, 2018 , we sold all of our mutual fund equity securities with gross realized losses of $957,000 . The Company recorded a $428,000 net loss in earnings resulting from the sale of these securities in the three months ended March 31, 2018. The remaining loss of $529,000 related to these sold securities was recorded as a transition adjustment upon adoption of ASU 2016-01 as of the beginning of the period as described in the preceding paragraph. There was a $1.2 million net gain in earnings resulting from sales of securities during the six months ended June 30, 2017 , that had previously been recorded as net unrealized gains of $744,000 in comprehensive income. Securities available for sale with market values of $18.1 million and $130.1 million as of June 30, 2018 and December 31, 2017 , respectively, were pledged to secure public deposits and for other purposes as required or permitted by law.

However, the allowance is an estimate that is inherently uncertain and depends on the outcome of future events. Management’s estimates are based on previous loss experience; size, growth and composition of the loan and lease portfolio; the value of collateral; and current economic conditions. Our lending is concentrated generally in real estate loans, commercial loans and leases and SBA loans to small and middle market businesses primarily in California, Texas, Illinois and New York.

Third party loan reviews are performed throughout the year. Additional adjustments are made when determined to be necessary. The loan and lease grade definitions are as follows: Pass and Pass-Watch: Pass and pass-watch loans and leases, grades 0-4, are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weaknesses as defined under Special Mention, Substandard or Doubtful. This category is the strongest level of the Bank’s loan and lease grading system. It incorporates all performing loans and leases with no credit weaknesses. It includes cash and stock/security secured loans or other investment grade loans. Special Mention: A special mention credit, grade 5, has potential weaknesses that deserve management’s close attention. If not corrected, these potential weaknesses may result in deterioration of the repayment prospects of the debt and result in a Substandard classification. Loans and leases that have significant actual, not potential, weaknesses are considered more severely classified. Substandard: A substandard credit, grade 6, has a well-defined weakness that jeopardizes the liquidation of the debt. A credit graded Substandard is not protected by the sound worth and paying capacity of the borrower, or of the value and type of collateral pledged. With a Substandard loan or lease, there is a distinct possibility that the Bank will sustain some loss if the weaknesses or deficiencies are not corrected. Doubtful: A doubtful credit, grade 7, is one that has critical weaknesses that would make the collection or liquidation of the full amount due improbable. However, there may be pending events which may work to strengthen the credit, and therefore the amount or timing of a possible loss cannot be determined at the current time. Loss: A loan or lease classified as loss, grade 8, is considered uncollectible and of such little value that its continuance as an active bank asset is not warranted. This classification does not mean that the loan or lease has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this asset even though partial recovery may be possible in the future. Loans and leases classified as loss are charged off in a timely manner. Under regulatory guidance, loans and leases graded special mention or worse are considered criticized loans and leases, and loans and leases graded substandard or worse are considered classified loans and leases.

We evaluate loan and lease impairment in accordance with GAAP. Impaired loans and leases are measured based on the present value of expected future cash flows discounted at the receivable's effective interest rate or, as a practical expedient, at the receivable's observable market price or the fair value of the collateral if the loan or lease is collateral dependent, less estimated costs to sell. If the measure of the impaired loan or lease is less than the recorded investment in the loan or lease, the deficiency is either charged off against the allowance for loan and lease losses or we establish a specific allocation in the allowance for loan and lease losses. Additionally, loans and leases that are considered impaired are specifically excluded from the quarterly migration analysis when determining the amount of the allowance for loan and lease losses required for the period. The allowance for collateral-dependent loans is determined by calculating the difference between the outstanding loan balance and the value of the collateral as determined by recent appraisals. The allowance for collateral-dependent loans varies from loan to loan based on the collateral coverage of the loan at the time of designation as nonperforming. We continue to monitor the collateral coverage, using recent appraisals, on these loans on a quarterly basis and adjust the allowance accordingly.

Nonaccrual Loans and Leases and Nonperforming Assets Loans and leases are placed on nonaccrual status when, in the opinion of management, the full timely collection of principal or interest is in doubt. Generally, the accrual of interest is discontinued when principal or interest payments become more than 90 days past due, unless management believes the receivable is adequately collateralized and in the process of collection. However, in certain instances, we may place a particular loan or lease receivable on nonaccrual status earlier, depending upon the individual circumstances surrounding the delinquency. When a receivable is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case interest payments are credited to income. Nonaccrual loans and leases may be restored to accrual status when principal and interest payments become current and full repayment is expected. The following table details nonaccrual loans and leases, excluding nonaccrual PCI loans of $1.7 million and $0.9 million as of June 30, 2018 and December 31, 2017, respectively, disaggregated by loan class, as of the dates indicated: June 30, 2018 December 31, 2017 (in thousands) Real estate loans: Commercial property Retail $ 225 $ 224 Hospitality 6,563 5,263 Other 1,184 2,462 Residential property 146 591 Total real estate loans 8,118 8,540 Commercial and industrial loans 2,110 1,892 Leases receivable 4,801 4,452 Consumer loans 775 921 Total nonaccrual loans and leases $ 15,804 $ 15,805 The following table details nonperforming assets as of the dates indicated: June 30, 2018 December 31, 2017 (in thousands) Nonaccrual loans and leases $ 15,804 $ 15,805 Loans and leases 90 days or more past due and still accruing — — Total nonperforming loans and leases 15,804 15,805 Other real estate owned ("OREO") 280 1,946 Total nonperforming assets $ 16,084 $ 17,751 OREO is included in prepaid expenses and other assets in the accompanying Consolidated Balance Sheets as of June 30, 2018 and December 31, 2017.

A debt restructuring is considered a TDR if we grant a concession, that we would not have otherwise considered, to the borrower for economic or legal reasons related to the borrower’s financial difficulties. Loans are considered to be TDRs if they were restructured through payment structure modifications such as reducing the amount of principal and interest due monthly and/or allowing for interest only monthly payments for three months or more. All TDRs are impaired and are individually evaluated for specific impairment using one of these three criteria: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral if the loan is collateral dependent. At June 30, 2018 and December 31, 2017 , $2.0 million and $2.2 million , respectively, of allowance relating to these loans were included in the allowance for loan and lease losses. For the restructured loans on accrual status, we determined that, based on the financial capabilities of the borrowers at the time of the loan restructuring and the borrowers’ past performance in the payment of debt service under the previous loan terms, performance and collection under the revised terms are probable.

These represented loans that have been sold for which the Bank continues to provide servicing. These loans are maintained off-balance sheet and are not included in the loans receivable balance. All of the loans serviced were SBA loans. The Company recorded servicing fee income of $1.2 million for each of the three month periods ended June 30, 2018 and 2017 . The Company recorded servicing fee income of $2.4 million for each of the six month periods ended June 30, 2018 and 2017 . Servicing fee income, net of the amortization of servicing assets and liabilities, is included in other operating income in the consolidated statements of income. Net amortization expense was $833,000 and $658,000 for the three months ended June 30, 2018 and 2017 , respectively, and $1.4 million and $1.1 million for the six months ended June 30, 2018 and 2017, respectively.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax expense was $5.9 million and $9.1 million representing an effective income tax rate of 27.5 percent and 38.5 percent for the three months ended June 30, 2018 and 2017 , respectively. The Company’s income tax expense was $11.6 million and $17.7 million representing an effective income tax rate of 27.7 percent and 38.5 percent for the six months ended June 30, 2018 and 2017 , respectively. Management concluded that as of June 30, 2018 and December 31, 2017 , a valuation allowance of $2.8 million was appropriate against certain state net operating losses and certain tax credits. For all other deferred tax assets, management believes it was more likely than not that these deferred tax assets will be realized principally through future taxable income and reversal of existing taxable temporary differences. A net deferred tax asset of $35.5 million and $32.5 million and a net current tax asset of $4.0 million and $5.8 million as of June 30, 2018 and December 31, 2017, respectively, are included in prepaid expenses and other assets in the accompanying Consolidated Balance Sheets. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). This ASU eliminates the stranded tax effects in other comprehensive income resulting from the Tax Cuts and Jobs Act (the “Tax Act”). Because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations was not affected. ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The Company adopted this standard as of January 1, 2018, and recorded the impact as an adjustment which increased retained earnings by $399,000 as of the date of adoption. The Tax Act was enacted into U.S. tax law on December 22, 2017. The Tax Act makes numerous changes to the U.S. tax code, including (although not limited to) reducing the U.S. federal corporate tax rate to 21 percent, eliminating the corporate alternative minimum tax (AMT), limiting deductible interest expense, increasing limitations on certain executive compensation, and enhancing bonus depreciation to provide for full expensing of qualified property. On that same date, the SEC staff also issued SAB 118, which provided guidance regarding financial statement accounting of the tax effects of the Tax Act. SAB 118 provides for the completion of the accounting related effects of the Tax Act in accordance with a measurement period of one year from the Tax Act enactment date. Those aspects of the Tax Act for which the accounting under ASC 740 is complete is to be reflected in the financial statements under SAB 118. To the extent that the company’s accounting for certain income taxes effects of the Tax Act is incomplete, however where a reasonable estimate is determinable, SAB 118 provides that a provisional estimate should be included in the financial statements. Finally, if a provisional estimate cannot be determined, a company should continue to apply ASC 740 based on the tax laws that were in effect immediately before the enactment of the Tax Act. During the year ended December 31, 2017 the Company made a provisional estimate of the impact of the Tax Act, which was discussed in Note 11 to our Consolidated Financial Statement included in our Form 10-K filed for that period. The Company is continuing to evaluate the impact of the Tax Act on its financial statements, and has not made any adjustments to this estimate during the period ended June 30, 2018. The Company is subject to examination by various federal and state tax authorities for certain years ended December 31, 2008 through 2016. As of June 30, 2018 , the Company was subject to audit or examination by the California Franchise Tax Board for the 2008 and 2009 tax years. Management does not anticipate any material changes in our financial statements as a result of these audits or examinations.

Debt Disclosure [Abstract]
Borrowings and Subordinated Debentures	Borrowings and Subordinated Debentures Borrowings The Bank had advances from the FHLB of $270.0 million and $150.0 million as of June 30, 2018 and December 31, 2017 , respectively. The FHLB advances were all overnight borrowings at June 30, 2018 and December 31, 2017 . For the three months ended June 30, 2018 and 2017 , interest expense on FHLB advances was $1.0 million and $49,000 , respectively, and the weighted-average interest rate was 1.90 percent and 0.98 percent , respectively. For the six months ended June 30, 2018 and 2017 , interest expense on FHLB advances was $1.7 million and $517,000 , respectively, and the weighted-average interest rate was 1.74 percent and 0.72 percent , respectively. The Bank maintains a secured credit facility with the FHLB, allowing the Bank to borrow on an overnight and term basis. The Bank had $1.1 billion of loans pledged as collateral with the FHLB, which provides $937.3 million in borrowing capacity, of which $557.3 million remained available at June 30, 2018 . The Bank also has securities with market values of $18.1 million pledged with the Federal Reserve Bank ("FRB"), which provides $17.4 million in available borrowing capacity through the Fed Discount Window. There were no outstanding borrowings with the FRB as of June 30, 2018 and December 31, 2017 . Subordinated Debentures The Company issued Fixed-to-Floating Subordinated Notes (the “Notes”) of $100 million on March 21, 2017, with a final maturity on March 30, 2027. The Notes have an initial fixed interest rate of 5.45% per annum, payable semi-monthly on March 30 and September 30 of each year. From and including March 30, 2022 and thereafter, the Notes bear interest at a floating rate equal to the then current three-month LIBOR, as calculated on each applicable date of determination, plus 3.315% payable quarterly. If the then current three-month LIBOR is less than zero, three-month LIBOR will be deemed to be zero. Debt issuance cost was $2.3 million , which is being amortized through the Notes' maturity date. At June 30, 2018 and December 31, 2017 , the balance of Notes included in the Company's consolidated balance sheet, net of debt issuance cost, was $98.1 million and $98.0 million , respectively. The amortization of debt issuance cost was $45,000 and $43,000 for the three months ended June 30, 2018 and 2017 , respectively, and $90,000 and $47,000 for the six months ended June 30, 2018 and 2017 , respectively. The Company assumed Junior Subordinated Deferrable Interest Debentures (“Subordinated Debentures”) as a result of the acquisition of Central Bancorp Inc. ("CBI") in 2014 with an unpaid principal balance of $26.8 million and an estimated fair value of $18.5 million . The $8.3 million discount is being amortized to interest expense through the debentures' maturity date of March 15, 2036. CBI formed a trust in 2005 and issued $26.0 million of Trust Preferred Securities (“TPS”) at 6.26 percent fixed rate for the first five years and a variable rate at the 3 month LIBOR plus 140 basis points thereafter and invested the proceeds in the Subordinated Debentures. The Company may redeem the Subordinated Debentures at an earlier date if certain conditions are met. The TPS will be subject to mandatory redemption if the Subordinated Debentures are repaid by the Company. Interest is payable quarterly , and the Company has the option to defer interest payments on the Subordinated Debentures from time to time for a period not to exceed five consecutive years. At June 30, 2018 and December 31, 2017 , the balance of Subordinated Debentures included in the Company's consolidated balance sheets, net of discount of $7.6 million and $7.7 million , was $19.4 million and $19.0 million , respectively. The amortization of discount was $86,000 and $81,000 for the three months ended June 30, 2018 , and 2017 , respectively, and $172,000 and $158,000 for the six months ended June 30, 2018 , and 2017 , respectively.

Earnings Per Share

Earnings Per Share	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per share (“EPS”) is calculated on both a basic and a diluted basis. Basic EPS excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted from the issuance of common stock that then shared in earnings, excluding common shares in treasury. For diluted EPS, weighted-average number of common shares included the impact of unvested restricted stock under the treasury method. Unvested restricted stock containing rights to non-forfeitable dividends are considered participating securities prior to vesting and have been included in the earnings allocation in computing basic and diluted EPS under the two-class method. Basic EPS is computed by dividing net income, net of income allocated to participating securities, by the weighted-average number of common shares. For diluted EPS, weighted-average number of common shares include the diluted effect of stock options. The following table is a reconciliation of the components used to derive basic and diluted EPS for the periods indicated: Three Months Ended Six Months Ended 2018 2017 2018 2017 (in thousands, except for share and per share data) Basic EPS: Net income $ 15,548 $ 14,457 $ 30,403 $ 28,240 Less: income allocated to unvested restricted shares 96 93 185 177 Income allocated to common shares $ 15,452 $ 14,364 $ 30,218 $ 28,063 Weighted-average shares for basic EPS 32,189,096 32,078,038 32,167,111 32,040,113 Basic EPS $ 0.48 $ 0.45 $ 0.94 $ 0.88 Effect of dilutive securities - options and unvested restricted stock 147,679 164,996 149,537 176,558 Diluted EPS: Income allocated to common shares $ 15,452 $ 14,364 $ 30,218 $ 28,063 Weighted-average shares for diluted EPS 32,336,775 32,243,034 32,316,648 32,216,671 Diluted EPS $ 0.48 $ 0.45 $ 0.94 $ 0.87 There were no stock options with an anti-dilutive effect for the three and six months ended June 30, 2018 or 2017.

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters In July 2013, the Board of Governors of the Federal Reserve, the Office of the Comptroller of the Currency and the FDIC approved the Basel III regulatory capital framework and related changes under the Dodd-Frank Wall Street Reform and Consumer Protection Act. The rules revise minimum capital requirements and adjust prompt corrective action thresholds. The rules also revise the regulatory capital elements, add a new common equity Tier I capital ratio, and increase the minimum Tier I capital ratio requirement. The revisions permit banking organizations to retain, through a one-time election, the existing treatment for accumulated other comprehensive income. Basel III rules, including certain transitional provisions, became effective January 1, 2015, and its requirements are included in the capital ratios presented in the table shown below. In addition, a new capital conservation buffer of 2.5% began to be phased in effective January 1, 2016 through January 1, 2019, and must be met to avoid limitations on the ability of the Bank to pay dividends, repurchase shares or pay discretionary bonuses. In January 2016, the new capital conservation buffer requirement was 0.625% of risk-weighted assets and will increase each year until fully implemented in January 2019. The Company and the Bank's capital conservation buffer was 6.35% and 6.86% , respectively, as of June 30, 2018 , and 6.55% and 7.20% , respectively, as of December 31, 2017 . As a result of the recently enacted Economic Growth, Regulatory Relief, and Consumer Protection Act, the federal banking agencies are required to develop a “Community Bank Leverage Ratio” (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies may consider a financial institution’s risk profile when evaluating whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies must set the minimum capital for the new Community Bank Leverage Ratio at not less than 8% and not more than 10%. A financial institution can elect to be subject to this new definition. The capital ratios of Hanmi Financial and the Bank as of June 30, 2018 and December 31, 2017 were as follows: Actual Minimum Regulatory Requirement Minimum to Be Categorized as “Well Capitalized” Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) June 30, 2018 Total capital (to risk-weighted assets): Hanmi Financial $ 704,262 15.17 % $ 371,336 8.00 % N/A N/A Hanmi Bank $ 690,123 14.86 % $ 371,465 8.00 % $ 464,332 10.00 % Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 573,034 12.35 % $ 278,502 6.00 % N/A N/A Hanmi Bank $ 656,948 14.15 % $ 278,599 6.00 % $ 371,465 8.00 % Common equity Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 553,555 11.93 % $ 208,876 4.50 % N/A N/A Hanmi Bank $ 656,948 14.15 % $ 208,949 4.50 % $ 301,815 6.50 % Tier 1 capital (to average assets): Hanmi Financial $ 573,034 10.83 % $ 211,655 4.00 % N/A N/A Hanmi Bank $ 656,948 12.42 % $ 211,663 4.00 % $ 264,579 5.00 % December 31, 2017 Total capital (to risk-weighted assets): Hanmi Financial $ 684,272 15.50 % $ 353,171 8.00 % N/A N/A Hanmi Bank $ 670,896 15.20 % $ 353,091 8.00 % $ 441,364 10.00 % Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 553,970 12.55 % $ 264,878 6.00 % N/A N/A Hanmi Bank $ 638,557 14.47 % $ 264,818 6.00 % $ 353,091 8.00 % Common equity Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 537,950 12.19 % $ 198,658 4.50 % N/A N/A Hanmi Bank $ 638,557 14.47 % $ 198,614 4.50 % $ 286,886 6.50 % Tier 1 capital (to average assets): Hanmi Financial $ 553,970 10.79 % $ 205,344 4.00 % N/A N/A Hanmi Bank $ 638,557 12.44 % $ 205,385 4.00 % $ 256,731 5.00 %

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures , defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are defined as follows: • Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2 - Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. • Level 3 - Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. We record securities available for sale at fair value on a recurring basis. Certain other assets, such as loans held for sale, impaired loans, OREO, and core deposit intangible, are recorded at fair value on a non-recurring basis. Non-recurring fair value measurements typically involve assets that are periodically evaluated for impairment and for which any impairment is recorded in the period in which the re-measurement is performed. The following methods and assumptions were used to estimate the fair value of each class of financial instrument below: Securities available for sale - The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges. If quoted prices are not available, fair values are measured using matrix pricing, which is a mathematical technique used widely 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, or other model-based valuation techniques requiring observable inputs other than quoted prices such as yield curve, prepayment speeds, and default rates. Level 1 securities include U.S. treasury securities and mutual funds that are traded on an active exchange or by dealers or brokers in active over-the-counter markets. The fair value of these securities is determined by quoted prices on an active exchange or over-the-counter market. Level 2 securities primarily include mortgage-backed securities, collateralized mortgage obligations, U.S. government agency securities, SBA loan pool securities, municipal bonds and corporate bonds in markets that are active. In determining the fair value of the securities categorized as Level 2, we obtain reports from nationally recognized broker-dealers detailing the fair value of each investment security held as of each reporting date. The broker-dealers use prices obtained from nationally recognized pricing services to value our fixed income securities. The fair value of the municipal securities is determined based on pricing data provided by nationally recognized pricing services. We review the prices obtained for reasonableness based on our understanding of the marketplace, and also consider any credit issues related to the bonds. As we have not made any adjustments to the market quotes provided to us and as they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy. Level 3 securities are instruments that are not traded in the market. As such, no observable market data for the instrument is available, which necessitates the use of significant unobservable inputs. Loans held for sale - Loans held for sale are all SBA loans and carried at the lower of cost or fair value. Management obtains quotes, bids or pricing indication sheets on all or part of these loans directly from the purchasing financial institutions. Premiums received or to be received on the quotes, bids or pricing indication sheets are indicative of the fact that cost is lower than fair value. At June 30, 2018 , the entire balance of SBA loans held for sale was recorded at its cost. We record SBA loans held for sale on a nonrecurring basis with Level 2 inputs. Impaired loans - Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. All impaired loans with a carrying balance over $250,000 are reviewed individually for the amount of impairment, if any. Nonaccrual loans with a carrying balance of $250,000 or less are evaluated for impairment collectively. For loans with a carrying balance of $250,000 or less which are over 90 days past due, regardless of accrual status, or part of an existing impaired credit relationship, the loan is reviewed individually for the amount of impairment, if any. The Company does not record loans at fair value on a recurring basis. However, from time to time, nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on either the current appraised value of the collateral, a Level 2 measurement, or management’s judgment and estimation of value reported on older appraisals that are then adjusted based on recent market trends, a Level 3 measurement. OREO - Fair value of OREO is based primarily on third party appraisals, less costs to sell and result in a Level 2 classification of the inputs for determining fair value. Appraisals are required annually and may be updated more frequently as circumstances require and the fair value adjustments are made to OREO based on the updated appraised value of the property. Assets and Liabilities Measured at Fair Value on a Recurring Basis As of June 30, 2018 and December 31, 2017 , assets and liabilities measured at fair value on a recurring basis are as follows: Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs with No Active Market with Identical Characteristics Significant Unobservable Inputs Balance (in thousands) June 30, 2018 Assets: Securities available for sale: Mortgage-backed securities $ — $ 322,851 $ — $ 322,851 Collateralized mortgage obligations — 121,389 — 121,389 U.S. government agency securities — 7,360 — 7,360 Municipal bonds-tax exempt — 113,929 — 113,929 Total securities available for sale $ — $ 565,529 $ — $ 565,529 December 31, 2017 Assets: Securities available for sale: Mortgage-backed securities $ — $ 303,609 $ — $ 303,609 Collateralized mortgage obligations — 117,768 — 117,768 U.S. government agency securities — 7,414 — 7,414 Municipal bonds-tax exempt — 127,475 — 127,475 U.S. treasury securities 152 — — 152 Mutual funds 22,386 — — 22,386 Total securities available for sale $ 22,538 $ 556,266 $ — $ 578,804 Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis As of June 30, 2018 and December 31, 2017 , assets and liabilities measured at fair value on a non-recurring basis are as follows: Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs With No Active Market With Identical Characteristics Significant Unobservable Inputs Loss During the Six Months Ended June 30, 2018 (in thousands) June 30, 2018 Assets: Impaired loans (1) $ — $ 4,407 $ 915 $ 2,463 OREO — 280 — — Loss During the Twelve Months Ended December 31, 2017 December 31, 2017 Assets: Impaired loans (2) $ — $ 6,121 $ 2,436 $ 2,730 OREO — 1,946 — — (1) Consist of real estate loans of $4.6 million and commercial and industrial loans of $730,000 . (2) Consist of real estate loans of $6.7 million , commercial and industrial loans of $1.7 million . ASC 825, Financial Instruments , requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured on a recurring basis or non-recurring basis are discussed above. The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data in order to develop estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Effective January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This standard, among other provisions, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Other than certain financial instruments for which we have concluded that the carrying amounts approximate fair value, the fair value estimates shown below have are based on an exit price notion as of June 30, 2018 , as required by ASU 2016-01. The financial instruments for which we have concluded that the carrying amounts approximate fair value include, cash and due from banks, accrued interest receivable and payable, FHLB stock, and noninterest-bearing deposits. The fair values of off-balance sheet items are based upon the difference between the current value of similar loans and the price at which the Bank has committed to make the loans. The estimated fair values of financial instruments were as follows: June 30, 2018 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks 136,474 136,474 — — Securities available for sale 565,529 — 565,529 — Loans and leases receivable, net of allowance for loan and lease losses 4,510,308 — — 4,453,997 Loans held for sale 5,349 — 6,451 — Accrued interest receivable 12,940 12,940 — — FHLB stock 16,385 — 16,385 — Financial liabilities: Noninterest-bearing deposits 1,350,383 — 1,350,383 — Interest-bearing deposits 3,076,152 — — 3,070,237 Borrowings and subordinated debentures 387,532 — 94,864 269,762 Accrued interest payable 5,775 5,775 — — Off-balance sheet items: Commitments to extend credit 354,894 — — 354,894 Standby letters of credit 24,702 — — 24,702 Commercial letters of credit 15,377 — — 15,377 December 31, 2017 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 153,826 $ 153,826 $ — $ — Securities available for sale 578,804 22,538 556,266 — Loans and leases receivable, net of allowance for loan and lease losses 4,273,415 — — 4,213,689 Loans held for sale 6,394 — 6,394 — Accrued interest receivable 12,770 12,770 — — FHLB stock 16,385 — 16,385 — Financial liabilities: Noninterest-bearing deposits 1,312,274 — 1,312,274 — Interest-bearing deposits 3,036,380 — — 2,973,139 Borrowings and subordinated debentures 267,270 — — 267,270 Accrued interest payable 5,309 5,309 — — Off-balance sheet items: Commitments to extend credit 318,634 — — 318,634 Standby letters of credit 19,294 — — 19,294 Commercial letters of credit 9,308 — — 9,308

Risks and Uncertainties [Abstract]
Off-Balance Sheet Commitments	Off-Balance Sheet Commitments The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved with on-balance sheet items recognized in the consolidated balance sheets. The Bank’s exposure to losses in the event of non-performance by the other party to commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for extending loan facilities to customers. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, was based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, premises and equipment, and income-producing or borrower-occupied properties. The following table shows the distribution of undisbursed loan commitments as of the dates indicated: June 30, 2018 December 31, 2017 (in thousands) Commitments to extend credit $ 354,894 $ 318,634 Standby letters of credit 24,702 19,294 Commercial letters of credit 15,377 9,308 Total undisbursed loan commitments $ 394,973 $ 347,236 The allowance for off-balance sheet items is maintained at a level believed to be sufficient to absorb probable losses related to these unfunded credit facilities. The determination of the allowance adequacy is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. Net adjustments to the allowance for off-balance sheet items are included in other operating expenses. Activity in the allowance for loan off-balance sheet items was as follows for the periods indicated: Three Months Ended Six Months Ended 2018 2017 2018 2017 (in thousands) Balance at beginning of period $ 1,323 $ 1,184 $ 1,296 $ 1,184 Provision (income) 34 (49 ) 61 (49 ) Balance at end of period $ 1,357 $ 1,135 $ 1,357 $ 1,135

Revenue Recognition

Revenue Recognition	6 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company also adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of January 1, 2018. ASU 2014-09 established a principles-based approach to recognizing revenue that applies to all contracts other than those covered by other authoritative U.S. GAAP guidance. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows are also required. ASU 2014-09 was to be effective for interim and annual periods beginning after December 15, 2016 and was to be applied on either a modified retrospective or full retrospective basis. In August 2015, the FASB issued ASU 2015-14 which deferred the original effective date for all entities by one year. Public business entities are required to apply the guidance in ASU 2015-14 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The standard’s core principle is that a company shall recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies generally are required to use more judgment and make more estimates than under prior guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. Subsequent to the issuance of ASU 2014-09, the FASB issued targeted updates to clarify specific implementation issues including ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , ASU No. 2016-10, Identifying Performance Obligations and Licensing , ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients , and ASU No. 2016-20. Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers . For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. Since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the new guidance did not have an impact on revenue most closely associated with our financial instruments, including interest income and expense. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including revenue streams associated with our noninterest income. Based on this assessment, the Company concluded that ASU 2014-09 did not change the method in which the Company currently recognizes revenue for these revenue streams. The Company's noninterest income primarily includes service charges on deposit accounts, trade finance and other service charges and fees, servicing income, bank-owned life insurance income and gains or losses on sale of SBA loans, PCI loans and securities. Based on our assessment of revenue streams related to the Company's noninterest income, we concluded that the Companies performance obligations for such revenue streams are typically satisfied as services are rendered. If applicable, the Company records contract liabilities, or deferred revenue, when payments from customers are received or due in advance of providing services to customers and records contract assets when services are provided to customers before payment is received or before payment is due. The Company’s noninterest revenue streams are largely based on transactional activities and since the Company generally receives payments for its services during the period or at the time services are provided, there are no contract asset or receivable balances as of June 30, 2018 . Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contra-revenue (i.e., gross versus net) and concluded that our Consolidated Statements of Income do not include any revenue streams that are impacted by such gross versus net provisions of the new standard. The Company adopted ASU 2014-09 and its related amendments on its required effective date of January 1, 2018 utilizing the modified retrospective approach. Since there was no impact upon adoption of this new standard, a cumulative effect adjustment to opening retained earnings was not deemed necessary.

Accounting Policies [Abstract]
Basis of Accounting	In management’s opinion, the accompanying unaudited consolidated financial statements of Hanmi Financial and its subsidiaries reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended June 30, 2018 , but are not necessarily indicative of the results that will be reported for the entire year or any other interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The aforementioned unaudited consolidated financial statements are prepared in conformity with GAAP and in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The interim information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “ 2017 Annual Report on Form 10-K”).
Use of Estimates	The preparation of interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Material estimates subject to change include, among other items, the determination of allowance for loan and lease losses and various other assets and liabilities measured at fair value. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Descriptions of our significant accounting policies are included in Note 1 - Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements in our 2017 Annual Report on Form 10-K. Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) and ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). Summaries of ASU 2016-01 and 2018-02 and the impact of their adoption are included in Notes 2 and 5 to the Consolidated Financial Statements, respectively. In addition to other provisions, ASU 2016-01 requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Beginning with the quarter ended March 31, 2018, the Company measured the fair value of certain financial instruments, included in Note 10 to the Consolidated Financial Statements, using an exit price notion. The Company also adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as of January 1, 2018, as required. ASU 2014-09 replaces existing revenue recognition guidance for contracts to provide goods or services to customers and amends existing guidance related to recognition of gains and losses on the sale of certain nonfinancial assets such as real estate. See Note 14 to the Consolidated Financial Statements for the impact of the adoption of this new standard on the Company's consolidated financial statements.
Fair Value Assumptions of Financial Instruments	The following methods and assumptions were used to estimate the fair value of each class of financial instrument below: Securities available for sale - The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges. If quoted prices are not available, fair values are measured using matrix pricing, which is a mathematical technique used widely 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, or other model-based valuation techniques requiring observable inputs other than quoted prices such as yield curve, prepayment speeds, and default rates. Level 1 securities include U.S. treasury securities and mutual funds that are traded on an active exchange or by dealers or brokers in active over-the-counter markets. The fair value of these securities is determined by quoted prices on an active exchange or over-the-counter market. Level 2 securities primarily include mortgage-backed securities, collateralized mortgage obligations, U.S. government agency securities, SBA loan pool securities, municipal bonds and corporate bonds in markets that are active. In determining the fair value of the securities categorized as Level 2, we obtain reports from nationally recognized broker-dealers detailing the fair value of each investment security held as of each reporting date. The broker-dealers use prices obtained from nationally recognized pricing services to value our fixed income securities. The fair value of the municipal securities is determined based on pricing data provided by nationally recognized pricing services. We review the prices obtained for reasonableness based on our understanding of the marketplace, and also consider any credit issues related to the bonds. As we have not made any adjustments to the market quotes provided to us and as they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy. Level 3 securities are instruments that are not traded in the market. As such, no observable market data for the instrument is available, which necessitates the use of significant unobservable inputs. Loans held for sale - Loans held for sale are all SBA loans and carried at the lower of cost or fair value. Management obtains quotes, bids or pricing indication sheets on all or part of these loans directly from the purchasing financial institutions. Premiums received or to be received on the quotes, bids or pricing indication sheets are indicative of the fact that cost is lower than fair value. At June 30, 2018 , the entire balance of SBA loans held for sale was recorded at its cost. We record SBA loans held for sale on a nonrecurring basis with Level 2 inputs. Impaired loans - Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. All impaired loans with a carrying balance over $250,000 are reviewed individually for the amount of impairment, if any. Nonaccrual loans with a carrying balance of $250,000 or less are evaluated for impairment collectively. For loans with a carrying balance of $250,000 or less which are over 90 days past due, regardless of accrual status, or part of an existing impaired credit relationship, the loan is reviewed individually for the amount of impairment, if any. The Company does not record loans at fair value on a recurring basis. However, from time to time, nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on either the current appraised value of the collateral, a Level 2 measurement, or management’s judgment and estimation of value reported on older appraisals that are then adjusted based on recent market trends, a Level 3 measurement. OREO - Fair value of OREO is based primarily on third party appraisals, less costs to sell and result in a Level 2 classification of the inputs for determining fair value. Appraisals are required annually and may be updated more frequently as circumstances require and the fair value adjustments are made to OREO based on the updated appraised value of the property.
Fair Value Measurements	ASC 825, Financial Instruments , requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured on a recurring basis or non-recurring basis are discussed above. The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data in order to develop estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Effective January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This standard, among other provisions, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Other than certain financial instruments for which we have concluded that the carrying amounts approximate fair value, the fair value estimates shown below have are based on an exit price notion as of June 30, 2018 , as required by ASU 2016-01. The financial instruments for which we have concluded that the carrying amounts approximate fair value include, cash and due from banks, accrued interest receivable and payable, FHLB stock, and noninterest-bearing deposits. The fair values of off-balance sheet items are based upon the difference between the current value of similar loans and the price at which the Bank has committed to make the loans.
