Explanation:

Money Supply is the concept that means the amount of the liquid financial products and total currency in the market or economy. It is regulated the macro-economically by the monetary policy. So, there are types of measures of money supply or stock:

-M0: narrowly, it means the hard currency in circulation

-MB: it equals M0+ the hard currency which are not technically in circulation and in bank reserves.

-M1: it is the most common one and equals M0 plus checking accounts plus travelers’ checks and other checkable deposits.

-M2: covers M1 and saving accounts and CDs.

-M3: it surrounds the larger deposits.

-MZM: finally, this indicates the money market deposits.

That’s why we could notice that M1 narrowly means the cash, checking account and travelers’ checks.
