(1) The total of financial instruments that are bought and held principally for the purpose of selling them in the near term (thus held for only a short period of time) or for debt and equity securities formerly categorized as available-for-sale or held-to-maturity which the entity held as of the date it opted to account for such securities at fair value. An enterprise may also categorize such a security as trading without the intent to sell it in the near term assuming the decision to categorize the security as trading occurred at acquisition; this is the reason why the trading category of investments in debt and equity securities are bought and sold "principally" for sale in the near term. Transfers into and out of the trading category should be rare. Such financial instruments that are held as of the reporting date are measured at fair value with unrealized holding gains and losses (the difference between fair value and the previously reported carrying amount) included in earnings. (2) Fair values as of the balance sheet date of all assets resulting from contracts that meet the criteria of being accounted for as derivative instruments, net of the effects of master netting arrangements.No authoritative reference available.false92jpm_SecuritiesjpmfalsedebitinstantmonetaryTotal debt and equity financial instruments classified as (1) available-for-sale securities and (2) held-to-maturity...falsefalsefalsefalsefalsefalsefalsefalsefalse1falsetrue360390000000360390falsefalse2falsetrue205943000000205943falsefalseTotal debt and equity financial instruments classified as (1) available-for-sale securities and (2) held-to-maturity securities. (1) For an unclassified balance sheet, this item represents investments in debt and equity securities which are categorized neither as held-to-maturity nor trading. Such securities are reported at fair value, with unrealized gains and losses excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale Security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain or loss of an Available-for-sale Security that is designated as being hedged in a fair value hedge shall be recognized in earnings during the period of the hedge, as should other than temporary declines in fair value below costs basis. (2) For an unclassified balance sheet, this item represents investments in debt securities which are categorized as held-to-maturity; such investments are measured at amortized cost (carrying value). The held-to-maturity category is for those securities that the Entity has the positive intent and ability to hold until maturity.No authoritative reference available.false102us-gaap_LoansAndLeasesReceivableNetOfDeferredIncomeus-gaaptruedebitinstantmonetaryNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalse1falsetrue633458000000633458falsefalse2falsetrue744898000000744898falsefalseNo definition available.No authoritative reference available.false112us-gaap_LoansAndLeasesReceivableAllowanceus-gaaptruecreditinstantmonetaryNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalse1falsetrue-31602000000-31602falsefalse2falsetrue-23164000000-23164falsefalseNo definition available.No authoritative reference available.true122us-gaap_LoansAndLeasesReceivableNetReportedAmountus-gaaptruedebitinstantmonetaryNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalse1falsetrue601856000000601856falsefalse2falsetrue721734000000721734falsefalseNo definition available.No authoritative reference available.false132jpm_AccruedInterestAndAccountsReceivablejpmfalsedebitinstantmonetaryAccrued interest and accounts receivable comprised of (1) accounts receivable and (2) accrued investment income.
