Business, Legal & Accounting Glossary
In the US, M1 is a narrow measure of the money supply. M1 is defined as all currency in circulation plus checking account deposits and other checkable deposits in banks, credit unions, and other depository institutions. Savings deposits, time deposits, and most other deposits at financial institutions are not included in M1. The deposits included in M1 are those that the Federal Reserve imposes reserve requirements on depository institutions for holding. M1 is sometimes called narrow money. M1 is very easy for the Federal Reserve to control through open market operations, but broader measures of the money supply such as M2 and M3 tend to have a stronger relationship to inflation. Unlike M1, M2 and M3 can be influenced by monetary policy only indirectly.
