Answer:
two
Step-by-step explanation:
The Fed defines money supply in two major monetary aggregates: M1 and M2.
The Fed considers M1 to be money that is held and circulating outside of banks, and does not include currency in bank vaults (including the Fed banks). M1 includes only circulating money and checkable deposits.
M2 includes M1 plus savings deposits, retail money market accounts and small denomination time deposits.
