Accounting Policies [Abstract]	'
Basis of Presentation	'
	1. Basis of Presentation:
	Peoples Financial Corporation (the “Company”) is a one-bank holding company headquartered in Biloxi, Mississippi. It 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 September 30, 2014 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 2013 Annual Report and Form 10-K.
	The results of operations for the quarter or nine months ended September 30, 2014, 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 with 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, 2013.
	New Accounting Pronouncements—In April 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-06, Technical Corrections and Improvements Related to Glossary Terms. This ASU added, deleted, corrected and modified terms in the Master Glossary of the Codification and was effective upon issuance. The adoption of this ASU did not have a material effect on the Company’s financial position, results of operations or cash flows. In August 2014, the FASB issued ASU No. 2014-14, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. This ASU requires that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if certain conditions are met. ASU No. 2014-14 is effective for annual periods and interim periods within those annual periods beginning after December 31, 2014. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 31, 2016, and interim periods within annual periods beginning after December 14, 2016. The adoption of ASU 2014-14 and ASU 2014-15 is not expected to have a material effect on the Company’s financial position, results of operations or cash flows.

At September 30, 2014, 7 of the 10 securities issued by the U.S. Treasury, 23 of the 29 securities issued by U.S. Government agencies, 7 of the 13 mortgage-backed securities and 21 of the 157 securities issued by states and political subdivisions contained unrealized losses.
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.
Securities with a fair value of $212,315,955 and $262,830,011 at September 30, 2014 and December 31, 2013, respectively, were pledged to secure public deposits, federal funds purchased and other balances required by law.
Proceeds from the sale of available for sale debt securities were $26,075,225 for the nine months ended September 30, 2013. Available for sale debt securities were sold for a realized gain of $257,997. There were no sales of available for sale securities in 2014.

	The Company monitors the credit quality of its loan portfolio through the use of a loan grading system. A score of 1 – 5 is assigned to the loan 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 - 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. Loans with a grade of C may be placed on the watch list if weaknesses are not resolved which could result in potential loss or for other circumstances that require monitoring. 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.

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.
	Federal Funds Sold
	The carrying amount shown as federal funds sold 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. The other 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. All of the Company’s available for sale securities are Level 2 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.
	Federal Funds Purchased and Securities Sold under Agreements to Repurchase
	The carrying amount shown as federal funds purchased and securities sold under agreements to repurchase approximates fair value.
	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 September 30, 2014 and December 31, 2013 are as follows (in thousands):

Accounting Policies [Abstract]	'
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.
Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies—The accounting and reporting policies of the Company conform with 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, 2013.
New Accounting Pronouncements	'
	New Accounting Pronouncements—In April 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-06, Technical Corrections and Improvements Related to Glossary Terms. This ASU added, deleted, corrected and modified terms in the Master Glossary of the Codification and was effective upon issuance. The adoption of this ASU did not have a material effect on the Company’s financial position, results of operations or cash flows. In August 2014, the FASB issued ASU No. 2014-14, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. This ASU requires that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if certain conditions are met. ASU No. 2014-14 is effective for annual periods and interim periods within those annual periods beginning after December 31, 2014. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 31, 2016, and interim periods within annual periods beginning after December 14, 2016. The adoption of ASU 2014-14 and ASU 2014-15 is not expected to have a material effect on the Company’s financial position, results of operations or cash flows.
