Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation: Peoples Financial Corporation (the “Company”) is a one-bank holding company headquartered in Biloxi, Mississippi. The Company has two operating subsidiaries, PFC Service Corp., an inactive company, and The Peoples Bank, Biloxi, Mississippi (the “Bank”). The Bank provides a full range of banking, financial and trust services to state, county and local government entities and individuals and small and commercial businesses operating in those portions of Mississippi, Louisiana and Alabama which are within a fifty mile radius of the Waveland, Wiggins and Gautier branches, the Bank’s three most outlying locations (the “trade area”). The accompanying unaudited consolidated financial statements and notes thereto contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly, in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the financial position of the Company and its subsidiaries as of March 31, 2016 and the results of their operations and their cash flows for the periods presented. The interim financial information should be read in conjunction with the annual consolidated financial statements and the notes thereto included in the Company’s 2015 Annual Report and Form 10-K. The results of operations for the quarter ended March 31, 2016, are not necessarily indicative of the results to be expected for the full year. Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses, the valuation of other real estate acquired in connection with foreclosure or in satisfaction of loans and valuation allowances associated with the realization of deferred tax assets, which are based on future taxable income. Summary of Significant Accounting Policies – The accounting and reporting policies of the Company conform to GAAP and general practices within the banking industry. There have been no material changes or developments in the application of principles or in our evaluation of the accounting estimates and the underlying assumptions or methodologies that we believe to be Critical Accounting Policies as disclosed in our Form 10-K for the year ended December 31, 2015. New Accounting Pronouncements – In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 82) In March 2016, FASB issued ASU 2016-03, Intangibles – Goodwill and Other (Topic 350); Business Combinations (Topic 805); Consolidation (Topic 810); Derivatives and Hedging (Topic 815): Effective Date and Transition Guidance. In March 2016, FASB issued ASU 2016-07, Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting

Management evaluates securities for other-than-temporary impairment on a monthly basis. In performing this evaluation, the length of time and the extent to which the fair value has been less than cost, the fact that the Company’s securities are primarily issued by U.S. Treasury and U.S. Government Agencies and the cause of the decline in value are considered. In addition, the Company does not intend to sell and it is not more likely than not that it will be required to sell these securities before maturity. While some available for sale securities have been sold for liquidity purposes or for gains, the Company has traditionally held its securities, including those classified as available for sale, until maturity. As a result of the evaluation of these securities, the Company has determined that the unrealized losses summarized in the tables above are not deemed to be other-than-temporary. Proceeds from sales and calls of available for sale debt securities were $19,590,781 during the three months ended March 31, 2016. Available for sale debt securities were sold or called for a realized gain of $72,333 for the three months ended March 31, 2016. There were no sales or calls of available for sale debt securities for the three months ended March 31, 2015. Securities with a fair value of $205,888,934 and $168,724,920 at March 31, 2016 and December 31, 2015, respectively, were pledged to secure public deposits, federal funds purchased and other balances required by law.

A score of 1 – 5 is assigned to the loan based on factors including repayment ability, trends in net worth and/or financial condition of the borrower and guarantors, employment stability, management ability, loan to value fluctuations, the type and structure of the loan, conformity of the loan to bank policy and payment performance. Based on the total score, a loan grade of A, B, C, S, D, E or F is applied. A grade of A will generally be applied to loans for customers that are well known to the Company and that have excellent sources of repayment. A grade of B will generally be applied to loans for customers that have excellent sources of repayment which have no identifiable risk of collection. A grade of C will generally be applied to loans for customers that have adequate sources of repayment which have little identifiable risk of collection. A grade of S will generally be applied to loans for customers who meet the criteria for a grade of C but who also warrant additional monitoring by placement on the watch list. A grade of D will generally be applied to loans for customers that are inadequately protected by current sound net worth, paying capacity of the borrower, or pledged collateral. Loans with a grade of D have unsatisfactory characteristics such as cash flow deficiencies, bankruptcy filing by the borrower or dependence on the sale of collateral for the primary source of repayment, causing more than acceptable levels of risk. Loans 60 to 89 days past due receive a grade of D. A grade of E will generally be applied to loans for customers with weaknesses inherent in the “D” classification and in which collection or liquidation in full is questionable. In addition, on a monthly basis the Company determines which loans are 90 days or more past due and assigns a grade of E to them. A grade of F is applied to loans which are considered uncollectible and of such little value that their continuance in an active bank is not warranted. Loans with this grade are charged off, even though partial or full recovery may be possible in the future. An analysis of the loan portfolio by loan grade, segregated by class of loans, as of March 31, 2016 and December 31, 2015, is as follows (in thousands): Loans With A Grade Of: A, B or C S D E F Total March 31, 2016: Gaming $ 31,492 $ $ $ $ $ 31,492 Residential and land development 610 309 919 Real estate, construction 32,514 725 2,210 35,449 Real estate, mortgage 168,381 16,541 23,019 12,937 220,878 Commercial and industrial 24,469 15,007 1,326 1,132 41,934 Other 7,121 1 117 7,239 Total $ 264,587 $ 31,549 $ 25,187 $ 16,588 $ $ 337,911 December 31, 2015: Gaming $ 31,655 $ $ $ $ $ 31,655 Residential and land development 610 323 933 Real estate, construction 31,935 883 2,596 35,414 Real estate, mortgage 167,286 16,678 23,686 12,275 219,925 Commercial and industrial 24,466 15,007 2,368 639 42,480 Other 7,114 1 35 7,150 Total $ 263,066 $ 31,686 $ 26,972 $ 15,833 $ $ 337,557 A loan may be impaired but not on nonaccrual status when the loan is well secured and in the process of collection.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Disclosures	8. Fair Value Measurements and Disclosures: The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale securities are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record other assets at fair value on a non-recurring basis, such as impaired loans and ORE. These non-recurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Additionally, the Company is required to disclose, but not record, the fair value of other financial instruments. Fair Value Hierarchy The Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1—Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2—Valuation is based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3—Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques. Following is a description of valuation methodologies used to determine the fair value of financial assets and liabilities. Cash and Due from Banks The carrying amount shown as cash and due from banks approximates fair value. Available for Sale Securities The fair value of available for sale securities is based on quoted market prices. The Company’s available for sale securities are reported at their estimated fair value, which is determined utilizing several sources. The primary source is Interactive Data Corporation, which utilizes pricing models that vary based on asset class and include available trade, bid and other market information and whose methodology includes broker quotes, proprietary models and vast descriptive databases. Another source for determining fair value is 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 securities. The Company’s available for sale securities for which fair value is determined through the use of such pricing models and matrix pricing are classified as Level 2 assets. If the fair value of available for sale securities is generated through model-based techniques, including the discounting of estimated cash flows, such securities are classified as Level 3 assets. Held to Maturity Securities The fair value of held to maturity securities is based on quoted market prices. Other Investments The carrying amount shown as other investments approximates fair value. Federal Home Loan Bank Stock The carrying amount shown as Federal Home Loan Bank Stock approximates fair value. Loans The fair value of fixed rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings for the remaining maturities. The cash flows considered in computing the fair value of such loans are segmented into categories relating to the nature of the contract and collateral based on contractual principal maturities. Appropriate adjustments are made to reflect probable credit losses. Cash flows have not been adjusted for such factors as prepayment risk or the effect of the maturity of balloon notes. The fair value of floating rate loans is estimated to be its carrying value. At each reporting period, the Company determines which loans are impaired. Accordingly, the Company’s impaired loans are reported at their estimated fair value on a non-recurring basis. An allowance for each impaired loan, which are generally collateral-dependent, is calculated based on the fair value of its collateral. The fair value of the collateral is based on appraisals performed by third-party valuation specialists. Factors including the assumptions and techniques utilized by the appraiser are considered by Management. If the recorded investment in the impaired loan exceeds the measure of fair value of the collateral, a valuation allowance is recorded as a component of the allowance for loan losses. Impaired loans are non-recurring Level 3 assets. Other Real Estate In the course of lending operations, Management may determine that it is necessary to foreclose on the related collateral. Other real estate acquired through foreclosure is carried at fair value, less estimated costs to sell. The fair value of the collateral is based on appraisals performed by third-party valuation specialists. Factors including the assumptions and techniques utilized by the appraiser are considered by Management. If the current appraisal is more than one year old and/or the loan balance is more than $200,000, a new appraisal is obtained. Otherwise, the Bank’s in-house property evaluator and Management will determine the fair value of the collateral, based on comparable sales, market conditions, Management’s plans for disposition and other estimates of fair value obtained from principally independent sources, adjusted for estimated selling costs. Other real estate is a non-recurring Level 3 asset. Cash Surrender Value of Life Insurance The carrying amount of cash surrender value of bank-owned life insurance approximates fair value. Deposits The fair value of non-interest bearing demand and interest bearing savings and demand deposits is the amount reported in the financial statements. The fair value of time deposits is estimated by discounting the cash flows using current rates of time deposits with similar remaining maturities. The cash flows considered in computing the fair value of such deposits are based on contractual maturities, since approximately 98% of time deposits provide for automatic renewal at current interest rates. Borrowings from Federal Home Loan Bank The fair value of Federal Home Loan Bank (“FHLB”) fixed rate borrowings is estimated using discounted cash flows based on current incremental borrowing rates for similar types of borrowing arrangements. The fair value of FHLB variable rate borrowings is estimated to be its carrying value. The balances of available for sale securities, which are the only assets measured at fair value on a recurring basis, by level within the fair value hierarchy and by investment type, as of March 31, 2016 and December 31, 2015 are as follows (in thousands): Fair Value Measurements Using Total Level 1 Level 2 Level 3 March 31, 2016: U.S. Treasuries $ 113,202 $ $ 113,202 $ U.S. Government agencies 52,947 52,947 Mortgage-backed securities 29,393 29,393 States and political subdivisions 21,734 21,554 180 Equity securities 608 608 Total $ 217,884 $ $ 217,704 $ 180 December 31, 2015: U.S. Treasuries $ 63,754 $ $ 63,754 $ U.S. Government agencies 84,546 84,546 Mortgage-backed securities 30,130 30,130 States and political subdivisions 23,727 23,547 180 Equity securities 650 650 Total $ 202,807 $ $ 202,627 $ 180 Impaired loans, which are measured at fair value on a non-recurring basis, by level within the fair value hierarchy as of March 31, 2016 and December 31, 2015 are as follows (in thousands): Fair Value Measurements Using Total Level 1 Level 2 Level 3 March 31, 2016 $ 7,752 $ $ $ 7,752 December 31, 2015 7,811 7,811 Other real estate, which is measured at fair value on a non-recurring basis, by level within the fair value hierarchy as of March 31, 2016 and December 31, 2015 are as follows (in thousands): Fair Value Measurements Using Total Level 1 Level 2 Level 3 March 31, 2016 $ 9,840 $ $ $ 9,840 December 31, 2015 9,916 9,916 The following table presents a summary of changes in the fair value of other real estate which is measured using level 3 inputs (in thousands): For the Three For the Year Months Ended Ended March 31, 2016 December 31, 2015 Balance, beginning of period $ 9,916 $ 7,646 Loans transferred to ORE 814 7,502 Sales (535 ) (4,295 ) Writedowns (355 ) (937 ) Balance, end of period $ 9,840 $ 9,916 The carrying value and estimated fair value of financial instruments, by level within the fair value hierarchy, at March 31, 2016 and December 31, 2015, are as follows (in thousands): Carrying Fair Value Measurements Using Amount Level 1 Level 2 Level 3 Total March 31, 2016: Financial Assets: Cash and due from banks $ 71,609 $ 71,609 $ $ $ 71,609 Available for sale securities 217,884 217,704 180 217,884 Held to maturity securities 21,743 22,046 22,046 Other investments 2,713 2,713 2,713 Federal Home Loan Bank stock 1,642 1,642 1,642 Loans, net 330,347 333,880 333,880 Other real estate 9,840 9,840 9,840 Cash surrender value of life insurance 18,884 18,884 18,884 Financial Liabilities: Deposits: Non-interest bearing 130,617 130,617 130,617 Interest bearing 450,618 450,891 450,891 Borrowings from Federal Home Loan Bank 8,333 9,857 9,857 December 31, 2015: Financial Assets: Cash and due from banks $ 31,396 $ 31,396 $ $ $ 31,396 Available for sale securities 202,807 202,627 180 202,807 Held to maturity securities 19,025 19,220 19,220 Other investments 2,744 2,744 2,744 Federal Home Loan Bank stock 1,637 1,637 1,637 Loans, net 329,487 331,026 331,026 Other real estate 9,916 9,916 9,916 Cash surrender value of life insurance 18,735 18,735 18,735 Financial Liabilities: Deposits: Non-interest bearing 122,743 122,743 122,743 Interest bearing 389,964 390,205 390,205 Borrowings from Federal Home Loan Bank 18,409 19,731 19,731

Use of Estimates	Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses, the valuation of other real estate acquired in connection with foreclosure or in satisfaction of loans and valuation allowances associated with the realization of deferred tax assets, which are based on future taxable income.
