Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Nature of Operations Pacific City Financial Corporation (collectively, with its consolidated subsidiary, "the Company," "we," "us" or "our") is a bank holding company whose subsidiary is Pacific City Bank ("the Bank"). The Bank is a single operating segment that operates eleven full-service branches in Los Angeles and Orange counties, California, one full-service branch in each of Fort Lee, New Jersey and Bayside, New York, and ten loan production offices in Irvine and Los Angeles, California; Lynnwood, Washington; Annandale, Virginia; Chicago, Illinois; Atlanta, Georgia; Bellevue, Washington; Aurora, Colorado; Carrollton, Texas; and New York, New York. The Bank offers a broad range of loans, deposits, and other products and services predominantly to small and middle market businesses and individuals. Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles ("GAAP") are not included herein. These interim statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s registration statement on Form S-1 filed with the SEC on July 17, 2018 (333-226208) and declared effective by the SEC on August 9, 2018. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary as of June 30, 2018 and December 31, 2017 and for the three and six months ended June 30, 2018 and 2017 . Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. Significant Accounting Policies The Company’s accounting policies are based upon GAAP and conform to predominant practices within the banking industry. The Company has not made any significant changes in its critical accounting policies from those disclosed in its registration statement on Form S-1 filed with the SEC on July 17, 2018 (333-226208) and declared effective by the SEC on August 9, 2018. Refer to Adopted Accounting Pronouncements below for discussion of accounting pronouncements adopted during the six months ended June 30, 2018 . Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates. Adopted Accounting Pronouncements During the six months ended June 30, 2018 , the following accounting pronouncements applicable to the Company were adopted: In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2014-09, " Revenue from Contracts with Customers (Topic 606)." This ASU clarifies principles for recognizing revenue from contracts with customers and supersedes current guidelines, Topic 605 - " Revenue Recognition," and most industry specific guidance. The principal of this ASU 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. To achieve this principle, an entity should apply the following "Five-steps Model" prescribed in Accounting Standard Codification ("ASC") 606: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. This ASU also specifies the accounting for some costs to obtain or fulfill a contract with a customer. The amended disclosure guidance requires 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. This ASU, as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12, ASU 2016-20, ASU 2017-13, and ASU 2017-14, is effective for interim and annual periods beginning after December 15, 2017, and entities have the option of using either a modified retrospective or full retrospective approach for the adoption. The Company adopted this guidance on January 1, 2018 utilizing the modified retrospective approach. The Company’s source of revenue is net interest income and noninterest income. The scope of this ASU explicitly excludes net interest income and other revenues from transactions involving financial instruments, such as loans and securities. The Company identified and reviewed fees and service charges on deposit accounts and income and expense from other real estate owned ("OREO"), which are within the scope of this ASU. Based on this analysis performed, the Company concluded this ASU did not have significant changes to the method in which the Company recognizes these revenue streams. Adoption of this ASU did not have a material impact on the Company's consolidated financial statements. See note 13 for additional information. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurements of Financial Assets and Financial Liabilities." The amendments in this ASU require 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; simplifies the impairment assessment of equity investments by requiring a qualitative assessment; eliminates the requirement for public business entities to disclose methods and assumptions for financial instruments measured at amortized cost on the statement of financial condition; requires the exit price notion to be used when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability; requires separate presentation of financial assets and liabilities by measurement category; and certain other requirements. This ASU became effective for fiscal years beginning after December 15, 2017. The Company adopted this guidance on January 1, 2018 and the adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. See note 2 for additional information. Recent Accounting Pronouncements Not Yet Adopted The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In February 2016, the FASB issued ASU 2016-02, " Leases (Topic 842)." The amendments in this ASU require lessees to recognize lease assets and lease liabilities for both leases classified as operating leases and finance leases, except leases with a term of 12 months or less where lessees are permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For leases with a term of greater than 12 months, lessees are required to recognize a liability to make lease payments and a right-of-use assets representing its right to use the underlying asset for the lease term measured at the present value of the lease payments. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for a public business entity. At June 30, 2018 , the future lease rental payable under non-cancelable operating lease commitments for the Company’s offices and loan production offices were $12.2 million . The Company is in the process of evaluating the impact that adoption of this ASU may have on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326)." The amendments in this ASU require that entities change the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. It includes financial assets such as loan receivables, held-to-maturity debt securities, net investment in leases that are not accounted for at fair value through net income, and certain off-balance sheet credit exposures. This ASU is effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has formed a committee that is assessing data and system needs in order to evaluate the impact of adopting this ASU. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which this ASU is effective. The Company is in the process of evaluating the impact that adoption of this ASU may have on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments in this ASU shorten the amortization period for certain callable debt securities acquired at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. The Company believes the adoption of this guidance will not have a material impact on its consolidated financial statements.

Fair Value Disclosures [Abstract]
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 the exchange price that would be received for an asset or paid to transfer a liability (i.e.; 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 observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value is measured 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 certain assets or liabilities for impairment or for disclosure purposes. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company records securities available-for-sale at fair value on a recurring basis. Certain other assets, such as loans held-for-sale, impaired loans, servicing assets and other real estate owned ("OREO") 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 is a description of valuation methodologies used for assets and liabilities recorded at fair value: Investment securities : The fair values of securities available-for-sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Management reviews the valuation techniques and assumptions used by the provider and determines that the provider uses widely accepted valuation techniques based on observable market inputs appropriate for the type of security being measured. Securities held-to-maturity are not measured at fair value on a recurring basis. Loans held-for-sale : The Company records SBA loans held-for-sale, residential property loans held-for-sale and certain non-residential real estate loans held-for-sale at the lower of cost or fair value, on an aggregate basis. The Company obtains fair values from a third party independent valuation service provider. Loans held-for-sale accounted for at the lower of cost or fair value are considered to be recognized at fair value when they are recorded at below cost, on an aggregate basis, and are classified as Level 2. Impaired loans : The Company records fair value adjustments on certain loans that reflect (i) partial write-downs, through charge-offs or specific reserve allowances, that are based on the current appraised or market-quoted value of the underlying collateral or (ii) the full charge-off of the loan carrying value. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. Fair value estimates for collateral-dependent impaired loans are obtained from real estate brokers or other third-party consultants, and are classified as Level 3. Servicing Assets: Servicing assets represent the value associated with servicing loans that have been sold. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates and prepayment speed assumptions as inputs. All of these assumptions require a significant degree of management estimation and judgment. The fair market valuation is performed on a quarterly basis for servicing assets. Servicing assets are accounted for at the lower of cost or market value and considered to be recognized at fair value when they are recorded at below cost and are classified as Level 3. Other real estate owned : The Company initially records OREO at fair value at the time of foreclosure. Thereafter, OREO is recorded at the lower of cost or fair value based on their subsequent changes in fair value. The fair value of OREO is generally based on recent real estate appraisals adjusted for estimated selling costs. 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 appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and result in a Level 3 classification due to the unobservable inputs used for determining fair value. Only OREO with a valuation allowance are considered to be carried at fair value.

Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on financial instruments both on and off the consolidated balance sheet without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Additionally, tax consequences related to the realization of the unrealized gains and losses can have a potential effect on fair value estimates and have not been considered in many of the estimates. The following methods and assumptions were used to estimate the fair value of significant financial instruments. Financial assets : The carrying amounts of interest-bearing deposits with other financial institutions and accrued interest receivable are considered to approximate fair value. The fair values of investment securities are generally based on matrix pricing (Level 2). The fair value of loans is estimated based on a discounted cash flow approach under an exit price notion for June 30, 2018 and an entry price notion for December 31, 2017. The fair value reflects the estimated yield that would be negotiated with a willing market participant. Because sale transactions of such loans are not readily observable, as many of the loans have unique risk characteristics, the valuation is based on significant unobservable inputs (Level 3). It is not practical to determine the fair value of Federal Home Loan Bank ("FHLB") and other restricted stock due to restrictions placed on its transferability. Financial liabilities : The carrying amounts of accrued interest payable are considered to approximate fair value. The fair value of deposits is estimated based on discounted cash flows. The discount rate is derived from the interest rates currently being offered for similar remaining maturities. Non-maturity deposits are estimated based on their historical decaying experiences (Level 3). The fair value of borrowings from FHLB is estimated based on discounted cash flows. The discount rate is derived from the current market rates for borrowings with similar remaining maturities (Level 2). Off-balance-sheet financial instruments : The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. The fair value of these financial instruments is not material and is excluded from the table below.

OTTI is recognized when fair value is below the amortized cost where: (i) an entity has the intent to sell the security; (ii) it is more likely than not that an entity will be required to sell the security before recovery of its amortized cost basis; or (iii) an entity does not expect to recover the entire amortized cost basis of the security. All individual securities in a continuous unrealized loss position for 12 months or more as of June 30, 2018 and December 31, 2017 had an investment grade rating upon purchase. The issuers of these securities have not established any cause for default on these securities and various rating agencies have reaffirmed their long-term investment grade status as of June 30, 2018 and December 31, 2017 . These securities have fluctuated in value since their purchase dates as market interest rates fluctuated. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell before the recovery of its amortized cost basis. In addition, the unrealized losses on municipal bonds are not considered other-than-temporary impaired, as the bonds are rated investment grade and there are no credit quality concerns with the issuers. Interest payments have been made as scheduled, and management believes this will continue in the future until the bonds get paid in full. The Company determined that the investment securities with unrealized losses for twelve months or more are not other-than-temporary impaired, and, therefore, no impairment was recognized during the three and six months ended June 30, 2018 and 2017 .

The Company analyzes loans individually by classifying the loans in regards to credit risk. This analysis typically includes non-homogeneous loans, such as commercial property and commercial and industrial loans, and is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings: Pass - Loans classified as pass include non-homogeneous loans not meeting the risk ratings defined below and smaller, homogeneous loans not assessed on an individual basis. Special Mention - Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of repayment prospects for the loan or of the institution’s credit position at some future date. Substandard - 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 classified as substandard 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. Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The restructuring of a loan includes, but is not limited to: (i) the transfer from the borrower to the Company of real estate, receivables from third parties, other assets, or an equity interest in full or partial satisfaction of the loan, (ii) a modification of the loan terms, such as a reduction of the stated interest rate, principal, or accrued interest or an extension of the maturity date at a stated interest rate lower than the current market rate for new debt with similar risk, or (iii) a combination of the above. A loan extended or renewed at a stated interest rate equal to the current interest rate for new debt with similar risk is not to be reported as a restructured loan.

When the Company subsequently changes its intent to hold certain loans, the loans are transferred to held-for-sale at the lower of cost or fair value. Certain loans are transferred to held-for-sale with write-downs to allowance for loan losses.

Transfers and Servicing [Abstract]
Servicing Assets	Servicing Assets At June 30, 2018 and December 31, 2017 , total servicing assets were $8.4 million and $9.0 million , respectively. Underlying loans being serviced at June 30, 2018 and December 31, 2017 totaled $540.0 million and $543.3 million , respectively. The Company sold loans of $18.5 million and $32.2 million , respectively, with the servicing rights retained and recognized a net gain on sale of $1.0 million and $2.3 million , respectively, during the three months ended June 30, 2018 and 2017 . During the six months ended June 30, 2018 and 2017 , the Company sold loans of $48.4 million and $68.3 million , respectively, with the servicing rights retained and recognized a net gain on sale of $3.1 million and $4.6 million , respectively.

All classes of servicing assets are measured using the amortization method and evaluated for impairment quarterly by comparing the fair value of the servicing right to the carrying amount. Fair value is estimated by stratifying the loans sold between mortgage and non-mortgage loans and discounting estimated future cash flows from the servicing assets using discount rates that approximate current market rates over the expected lives of the loans being serviced. For the purposes of measuring impairment, the Company has identified each servicing asset with the underlying loan being serviced, and a valuation allowance is recorded when the fair value is below the carrying amount. During the three and six months ended June 30, 2018 , the Company recorded a valuation allowance of $63 thousand on mortgage loan servicing assets. No valuation allowance was recorded during the three and six months ended June 30, 2017 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was $2.0 million and $3.6 million , respectively, and the effective tax rate was 29.9% and 42.4% , respectively, for the three months ended June 30, 2018 and 2017 . For the six months ended June 30, 2018 and 2017 , income tax expense was $4.7 million and $6.8 million , respectively, and the effective tax rate was 29.9% and 42.4% , respectively. The decrease in effective tax rate was mainly due to a decrease in the federal statutory tax rate from 35% to 21% as a result of H.R. 1, originally known (and referred to below) as the Tax Cuts and Jobs Act, which became effective on January 1, 2018. At June 30, 2018 and December 31, 2017 , the Company had no unrecognized tax benefits, or accrued interest or penalties. In the event the Company is assessed interest and/or penalties by federal or state tax authorities, such amounts will be classified in the consolidated financial statements as income tax expense. The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax in multiple state jurisdictions. The Company is no longer subject to the assessment of U.S. federal income tax for years before 2014. The statute of limitations for the assessment of California Franchise taxes has expired for tax years before 2013 (other state income and franchise tax statutes of limitations vary by state). On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law and brought with it significant changes to the U.S Internal Revenue Code of 1986, as amended, that impact corporate taxation requirements. At June 30, 2018 , the Company did not have any material adjustments to the items previously recorded at year-end 2017 related to the tax reform legislation. At December 31, 2017, the Company early adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which allowed a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. As a result of the adoption, the Company recorded a decrease in accumulated other comprehensive income of $242 thousand and an increase in retained earnings for the same amount to eliminate the stranded tax effects at that date from the reduction in the federal statutory tax rate that was enacted in December 22, 2017 and became effective January 1, 2018.

As of June 30, 2018 and December 31, 2017 , the Company had the following outstanding financial commitments whose contractual amount represents credit risk: ($ in thousands) June 30, 2018 December 31, 2017 Commitments to extend credit $ 112,302 $ 109,835 Standby letters of credit 3,384 3,309 Commercial letters of credit 815 233 Total $ 116,501 $ 113,377 The Company’s exposure to loan loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for the loans reflected in the consolidated financial statements. The Company maintained reserve for off-balance sheet items of $117 thousand and $121 thousand , respectively, at June 30, 2018 and December 31, 2017 . Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. The Company evaluates each client’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company is based on management’s credit evaluation of the customer. As of June 30, 2018 and December 31, 2017 , the Company had operating lease commitments of $12.2 million and $12.7 million , respectively. Litigation The Company is involved in various matters of litigation, which have arisen in the ordinary course of business. In the opinion of management, the disposition of pending matters of litigation will not have a material effect on the Company’s consolidated financial statements.

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks ("Basel III rules") became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, the Company must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.50% by 2019. Management believes as of June 30, 2018 and December 31, 2017 , the Company and the Bank met all capital adequacy requirements to which they are subject. The Company and the Bank's capital conservation buffer was 5.46% and 5.40% , respectively, as of June 30, 2018 , and 5.20% and 5.12% , respectively, as of December 31, 2017 . The following table presents the regulatory capital amounts and ratios for the Company and the Bank as of dates indicated: Actual Minimum Capital Requirement To Be Well Capitalized Under Prompt Corrective Provisions ($ in thousands) Amount Ratio Amount Ratio Amount Ratio June 30, 2018 Pacific City Financial Corporation Common tier 1 capital (to risk-weighted assets) $ 152,878 12.4 % $ 55,355 4.5 % N/A N/A Total capital (to risk-weighted assets) 165,616 13.5 % 98,408 8.0 % N/A N/A Tier 1 capital (to risk-weighted assets) 152,878 12.4 % 73,806 6.0 % N/A N/A Tier 1 capital (to average assets) 152,878 9.6 % 63,838 4.0 % N/A N/A Pacific City Bank Common tier 1 capital (to risk-weighted assets) $ 152,101 12.4 % $ 55,350 4.5 % $ 79,950 6.5 % Total capital (to risk-weighted assets) 164,839 13.4 % 98,400 8.0 % 123,000 10.0 % Tier 1 capital (to risk-weighted assets) 152,101 12.4 % 73,800 6.0 % 98,400 8.0 % Tier 1 capital (to average assets) 152,101 9.5 % 63,835 4.0 % 79,793 5.0 % December 31, 2017 Pacific City Financial Corporation Common tier 1 capital (to risk-weighted assets) $ 142,370 12.2 % $ 52,730 4.5 % N/A N/A Total capital (to risk-weighted assets) 154,715 13.2 % 93,766 8.0 % N/A N/A Tier 1 capital (to risk-weighted assets) 142,370 12.2 % 70,306 6.0 % N/A N/A Tier 1 capital (to average assets) 142,370 10.0 % 56,891 4.0 % N/A N/A Pacific City Bank Common tier 1 capital (to risk-weighted assets) $ 141,361 12.1 % $ 52,747 4.5 % $ 76,189 6.5 % Total capital (to risk-weighted assets) 153,705 13.1 % 93,723 8.0 % 117,153 10.0 % Tier 1 capital (to risk-weighted assets) 141,361 12.1 % 70,329 6.0 % 93,772 8.0 % Tier 1 capital (to average assets) 141,361 9.9 % 56,886 4.0 % 71,107 5.0 % The California Financial Code provides that a bank may not make a cash distribution to its shareholders in excess of the lesser of the bank’s undivided profits or the bank’s net income for its last three fiscal years less the amount of any distribution made to the bank’s shareholder during the same period. As a California corporation, the Company is subject to the limitations of California law, which allows a corporation to distribute cash or property to shareholders, including a dividend or repurchase or redemption of shares, if the corporation meets either a retained earnings test or a “balance sheet” test. Under the retained earnings test, the Company may make a distribution from retained earnings to the extent that its retained earnings exceed the sum of (a) the amount of the distribution plus (b) the amount, if any, of dividends in arrears on shares with preferential dividend rights. The Company may also make a distribution if, immediately after the distribution, the value of its assets equals or exceeds the sum of (a) its total liabilities plus (b) the liquidation preference of any shares which have a preference upon dissolution over the rights of shareholders receiving the distribution. Indebtedness is not considered a liability if the terms of such indebtedness provide that payment of principal and interest thereon are to be made only if, and to the extent that, a distribution to shareholders could be made under the balance sheet test.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," and all subsequent ASUs that are related to Topic 606. As stated in Note 1, the implementation of the new standard did not have a material impact on the measurement, timing, or recognition of revenue. Accordingly, no cumulative effect adjustment to opening retained earnings was deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as gain or loss associated with mortgage servicing assets and financial guarantees are also not within the scope of the new guidance. Topic 606 is applicable to noninterest income such as deposit related fees, interchange fees, and merchant related income. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Noninterest income considered to be within the scope of Topic 606 is discussed below. Service charges and fees on deposits : Deposit account service charges consist of monthly service fees, account analysis fees, non-sufficient funds ("NSF") charges and other deposit related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. NSF charges, and other deposit account service charges are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time as incurred. Debit card fees : When customers use their debit cards to pay merchants for goods or services, the Company retains a fee from the funds collected from the related deposit account and transfers the remaining funds to the payment network for remittance to the merchant. The performance obligation to the merchant is satisfied and the fee is recognized at the point in time when the funds are collected and transferred to the payment network. Gain (loss) on sale of other real estate owned : The Company's performance obligation for sale of OREO is the transfer of title and ownership rights of the OREO to the buyer, which occurs at the settlement date when the sale proceeds are received and income is recognized. Wire transfer fees and other service charges : Wire transfer fees and other service charges are transaction based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time as incurred. The following table presents revenue from contracts with customers within the scope of ASC 606 for the periods indicated: Three Months Ended June 30, Six Months Ended June 30, ($ in thousands) 2018 2017 2018 2017 Noninterest Income In scope of Topic 606 Service charges and fees on deposits: Monthly service fees $ 27 $ 26 $ 52 $ 51 Account analysis fees 241 227 476 443 Non-sufficient funds charges 86 61 153 147 Other deposit related fees 22 23 44 46 Total service charges and fees on deposits 376 337 725 687 Debit card fees 50 49 95 97 Gain (loss) on sale of other real estate owned — (5 ) 3 (6 ) Wire transfer fees 122 109 226 208 Other service charges 49 46 113 91 Total noninterest income in-scope of Topic 606 $ 597 $ 536 $ 1,162 $ 1,077

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Dividend Declared on Common Stock. On July 17, 2018 , the Company declared a quarterly cash dividend of $0.03 per common share for the third quarter of 2018. The dividend was paid on September 14, 2018 , to shareholders of record as of the close of business on August 31, 2018 . Completion of Initial Public Offering. On August 14, 2018 , the Company issued and sold 2,385,000 shares of its common stock in an underwritten public offering, for net proceeds of approximately $43.2 million after deducting underwriting discounts and commissions and estimated offering expenses. The underwriters were granted a 30 -day option to purchase up to an additional 357,750 shares of common stock at the initial public offering price less the underwriting discount. On September 5, 2018 , the Company issued an additional 123,234 shares of its common stock upon the exercise by the underwriters of a portion of their 30 -day option, for additional net proceeds of approximately $2.3 million . Concurrently with the initial public offering, the Company's common stock began trading on the Nasdaq Global Select Market under the symbol "PCB." The Company has evaluated the effects of events that have occurred subsequent to June 30, 2018 through the issuance date of these consolidated financial statements (unaudited). Other than the events described above, there have been no material events that would require disclosure in the consolidated financial statements or in the notes to the consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles ("GAAP") are not included herein. These interim statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s registration statement on Form S-1 filed with the SEC on July 17, 2018 (333-226208) and declared effective by the SEC on August 9, 2018. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary as of June 30, 2018 and December 31, 2017 and for the three and six months ended June 30, 2018 and 2017 . Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates.
Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Adopted Accounting Pronouncements During the six months ended June 30, 2018 , the following accounting pronouncements applicable to the Company were adopted: In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2014-09, " Revenue from Contracts with Customers (Topic 606)." This ASU clarifies principles for recognizing revenue from contracts with customers and supersedes current guidelines, Topic 605 - " Revenue Recognition," and most industry specific guidance. The principal of this ASU 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. To achieve this principle, an entity should apply the following "Five-steps Model" prescribed in Accounting Standard Codification ("ASC") 606: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. This ASU also specifies the accounting for some costs to obtain or fulfill a contract with a customer. The amended disclosure guidance requires 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. This ASU, as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12, ASU 2016-20, ASU 2017-13, and ASU 2017-14, is effective for interim and annual periods beginning after December 15, 2017, and entities have the option of using either a modified retrospective or full retrospective approach for the adoption. The Company adopted this guidance on January 1, 2018 utilizing the modified retrospective approach. The Company’s source of revenue is net interest income and noninterest income. The scope of this ASU explicitly excludes net interest income and other revenues from transactions involving financial instruments, such as loans and securities. The Company identified and reviewed fees and service charges on deposit accounts and income and expense from other real estate owned ("OREO"), which are within the scope of this ASU. Based on this analysis performed, the Company concluded this ASU did not have significant changes to the method in which the Company recognizes these revenue streams. Adoption of this ASU did not have a material impact on the Company's consolidated financial statements. See note 13 for additional information. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurements of Financial Assets and Financial Liabilities." The amendments in this ASU require 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; simplifies the impairment assessment of equity investments by requiring a qualitative assessment; eliminates the requirement for public business entities to disclose methods and assumptions for financial instruments measured at amortized cost on the statement of financial condition; requires the exit price notion to be used when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability; requires separate presentation of financial assets and liabilities by measurement category; and certain other requirements. This ASU became effective for fiscal years beginning after December 15, 2017. The Company adopted this guidance on January 1, 2018 and the adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. See note 2 for additional information. Recent Accounting Pronouncements Not Yet Adopted The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In February 2016, the FASB issued ASU 2016-02, " Leases (Topic 842)." The amendments in this ASU require lessees to recognize lease assets and lease liabilities for both leases classified as operating leases and finance leases, except leases with a term of 12 months or less where lessees are permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For leases with a term of greater than 12 months, lessees are required to recognize a liability to make lease payments and a right-of-use assets representing its right to use the underlying asset for the lease term measured at the present value of the lease payments. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for a public business entity. At June 30, 2018 , the future lease rental payable under non-cancelable operating lease commitments for the Company’s offices and loan production offices were $12.2 million . The Company is in the process of evaluating the impact that adoption of this ASU may have on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326)." The amendments in this ASU require that entities change the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. It includes financial assets such as loan receivables, held-to-maturity debt securities, net investment in leases that are not accounted for at fair value through net income, and certain off-balance sheet credit exposures. This ASU is effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has formed a committee that is assessing data and system needs in order to evaluate the impact of adopting this ASU. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which this ASU is effective. The Company is in the process of evaluating the impact that adoption of this ASU may have on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments in this ASU shorten the amortization period for certain callable debt securities acquired at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this ASU to annual periods beginning after December 15, 2018, including interim periods. The Company believes the adoption of this guidance will not have a material impact on its consolidated financial statements.
