Liquid assets held by individuals and banks. The money supply includes coins, currency, and demand deposits (checking accounts). Some economists consider time and savings deposits to be part of the money supply because such deposits can be managed by governmental action and are nearly as liquid as currency and demand deposits. Other economists believe that deposits in mutual savings banks, savings and loan associations, and credit unions should be counted as part of the money supply. Central banks regulate the money supply to stabilize their national economies. See alsomonetary policy.
