M1 vs M2 Money Supply Quiz: Narrow vs Broad Money

M1 is the narrowest measure of the money supply and includes the most liquid forms of money: currency in circulation, demand deposits such as checking accounts, and other liquid deposits. These are assets that can be used directly and immediately for everyday purchases and transactions.

M2 is a broader measure of money that includes everything counted in M1, plus near-money assets such as savings accounts, small-denomination time deposits, and retail money market funds. These M2 components are slightly less liquid than M1 but can still be converted to cash relatively quickly.

Checking account deposits are part of M1 because they are highly liquid and used directly for transactions. Savings accounts are included in M2 because they are slightly less liquid, meaning they are not typically used for daily purchases but can be accessed relatively easily when needed.

Small-denomination time deposits, such as certificates of deposit under a certain threshold, are included in M2 but not M1. They are considered near-money because they are not immediately available for transactions without potential penalties, but they are still a relatively liquid form of savings.

Currency held in bank vaults is not counted in M1. Only currency that is in circulation, meaning held by the public outside of banks, is included in M1. Vault cash is part of a bank's reserves, not money actively circulating in the economy for use in everyday transactions.

M2 is broader than M1 because it captures a wider range of financial assets. In addition to the highly liquid M1 components, M2 adds near-money items like savings accounts and money market funds that are not instantly available for transactions but can be converted to spending power fairly quickly.

M1 includes currency in circulation and demand deposits such as checking accounts because both are immediately available and widely accepted for making payments. Savings accounts and retail money market funds are part of M2 because they require an extra step before being used directly in transactions.

M1 tracks the most liquid assets in the economy, including currency and demand deposits that can be used immediately for transactions. It gives a snapshot of the money that is actively circulating in the economy at any given time, making it the most direct measure of day-to-day spending power.

M2 can increase without a corresponding increase in M1. For example, if individuals move money from checking accounts into savings accounts, M1 decreases while M2 stays the same or grows. Movements between M1 and M2 components affect the measures differently since M1 is a subset of M2.

When a bank grants a loan and deposits the funds into a checking account, it creates new demand deposits, which directly increases M1. This is how bank lending expands the money supply. The other options involve financial transactions that do not directly increase the most liquid components of M1.

The essential distinction between M1 and M2 is liquidity. M1 consists of assets that are immediately available for spending, such as cash and checking accounts. M2 extends this to include slightly less liquid assets like savings accounts that require a short conversion process before being used for direct purchases.

The Federal Reserve monitors money supply measures including M1 and M2 to assess economic conditions and guide monetary policy. Changes in these measures can signal inflationary or recessionary pressures, helping the Fed decide whether to expand or contract the money supply to maintain economic stability.

Near-money assets in M2 that are not in M1 include savings account balances, small-denomination certificates of deposit, and retail money market fund balances. These are not directly used for everyday transactions but can be converted to spendable money with relative ease, making them part of the broader M2 measure.

Transferring funds from a checking account to a savings account removes money from M1, because checking deposits are part of M1 but savings deposits are not. However, both accounts are part of M2, so the total M2 amount stays the same. This shift illustrates the compositional differences between the two measures.

Tracking both M1 and M2 gives a more complete view of economic conditions. M1 reflects immediate spending power, while M2 includes near-liquid savings that could enter circulation soon. Together, they help economists and the Federal Reserve understand how much money is available and how it might influence prices and economic activity.
