Total US Money in Circulation and Key Definitions
US money in circulation refers to physical currency, coins, and certain liquid bank deposits. The Federal Reserve tracks this through monetary aggregates like M1 and M2. M1 includes physical cash, demand deposits, and other checkable deposits. M2 adds savings deposits, small time deposits, and retail money market funds. These measures show how much money is actively available in the economy. The latest data shows M1 at around 2.1 trillion dollars and M2 around 21 trillion dollars, reflecting both everyday cash and near-money assets.
Physical currency in circulation has grown steadily as the US economy expands and global demand for dollars rises. The Bureau of Engraving and Printing produces Federal Reserve notes, while the US Mint produces coins. Most physical dollars are held outside the United States, which supports the role of the dollar as a global reserve currency. The Federal Reserve adjusts the monetary base through open market operations and reserve requirements. Changes in the money supply influence interest rates, inflation, and lending activity across financial markets.
M1 Money Supply: Components and Recent Trends
What Counts in M1
M1 includes coins, paper currency, demand deposits, and other checkable deposits held at commercial banks. Traveler's checks and certain negotiable instruments were historically part of M1 but now play a smaller role. The Federal Reserve publishes M1 data weekly in its H.6 release. M1 represents the most liquid part of the money supply, meaning it can be used directly for transactions. A rise in M1 often signals increased spending and economic activity, while a decline may point to tighter liquidity conditions.
Drivers of M1 Growth
M1 growth has been influenced by fiscal stimulus payments, bank lending, and changes in consumer spending habits. During periods of economic recovery, demand deposits often rise as businesses and households use checking accounts more actively. The Federal Reserve's interest rate decisions affect how banks lend and how much money moves through M1. For more context on how the Federal Reserve manages the money supply, see the official Federal Reserve Monetary Policy page. In recent cycles, M1 has shown sharp swings as pandemic-era support programs rolled out and then wound down.
M2 Money Supply: Broader Money Measures
What Counts in M2
M2 includes all of M1 plus savings deposits, small time deposits under 100000 dollars, and retail money market mutual fund shares. These components represent money that is still relatively liquid but may require a short conversion period before spending. M2 gives a broader view of the money available for spending and saving in the economy. The Federal Reserve uses M2 to monitor inflationary pressures and overall financial stability. A steady increase in M2 can signal growing wealth and lending activity, while rapid expansion may raise inflation concerns.
M2 and Its Role in the Economy
M2 growth reflects household and business decisions about saving, borrowing, and investing. When interest rates are low, savings and money market balances may rise as investors seek safe assets. The Federal Reserve's balance sheet actions, including asset purchases and sales, directly affect the reserves that banks use to support M2 components.

Changes in M2 help economists and policymakers assess the stance of monetary policy and its impact on real economic activity.
