Answer:
Neither M1 nor M2
Step-by-step explanation:
The money supply can be defined as the stock of currency and other liquid instruments circulating in an economy at a particular time. It includes cash, coins, savings accounts, the balance held in checking accounts and other near money instruments.
These four definitions of money, M1, M2, M3, and M4. A credit card is not included in any of these. It is not considered as money. Holding a credit card does not change the money supply.
Instead of money, it is rather considered a short term loan. Money is a financial asset while credit card debts are liabilities. So they will not be included in M1 or M2.
