Question

What types of money are included in the M2 category? Check all that apply.

currency
savings accounts
checking accounts
commodity money
short-term investment accounts

Answer 1

Included: currency, savings accounts, checking accounts.

Not included: commodity money, and (generally) generic "short-term investment accounts" — only specific short-term instruments that count toward M2 are small-denomination time deposits and retail money‑market mutual funds; other short-term investments (T-bills, large time deposits, commercial paper, etc.) are not in M2.
