Also found in: Dictionary, Thesaurus, Medical, Acronyms, Encyclopedia.
A measure of money supply used by the various central banks. In the Federal Reserve System, M3 includes all physical currency and deposits in checking accounts, deposits in savings accounts, certificates of deposit, institutional money market accounts, repurchase agreements, and other large liquid assets that do not circulate very often. The European Central Bank defines M3 as the aggregation of currency in circulation, overnight deposits, all money market accounts, debt securities with maturities of up to two years, and repurchase agreements. M3 includes money that circulates very little or not at all and, therefore, the Federal Reserve no longer calculates M3 when determining the money supply. However, it is useful to some economists seeking to determine the entire amount of money in a given economy. See also: M0, M1, M2, M4
A very broad measure of the domestic money supply that includes M2 items plus any large time deposits and money market fund balances held by institutions.
