What constitutes money supply?

Money supply refers to the total amount of money available in an economy at a specific time. It typically includes various forms of money, such as currency in circulation (coins and banknotes), demand deposits (checking accounts), and other liquid assets like savings accounts. Economists often categorize money supply into different measures, such as M1 (physical cash and checking accounts) and M2 (M1 plus savings accounts and other near-money assets). The money supply is a critical factor in determining economic activity, inflation, and interest rates.
