What is Monetary Base

A monetary base is the total amount of a currency that is either in general circulation in the hands of the public or in the commercial bank deposits held in the central bank’s reserves. This measure of the money supply typically only includes the most liquid currencies; it is also known as the “money base.”


Breaking Down Monetary Base

The monetary base is a component of a nation’s money supply. It refers strictly to highly liquid funds including notes, coinage and current bank deposits. When the Federal Reserve creates new funds to purchase bonds from commercial banks, the banks see an increase in their holdings, which causes the monetary base to expand.
