Money supply

19 January, 2016 - 11:14

The most common measures are named M0 (narrowest), M1, M2, and M3. In the United States they are defined by the Federal Reserve as follows:

Measure Definition
M0 The total of all physical currency, plus accounts at the central bank that can be exchanged for physical currency.
M1 M0 + those portions of M0 held as reserves or vault cash + the amount in demand accounts ("checking" or "current" accounts).
M2 M1 + most savings accounts, money market accounts, and small denomination time deposits (certificates of deposit of under $100,000).
M3 M2 + all other CDs, deposits of eurodollars and repurchase agreements.

The Federal Reserve stopped publishing M3 statistics in March 2006, saying that the data cost a lot to collect but did not provide significantly useful information 1. The other three money supply measures continue to be provided in detail.
