Current Size of US Money in Circulation
As of the latest Federal Reserve data, the total amount of US money in circulation measured by M2 exceeds 21 trillion dollars, while M1 stands above 11 trillion dollars. The Federal Reserve reports these figures monthly through its H.6 release, which tracks currency in circulation, demand deposits, and other liquid components. This growth reflects both physical cash held by the public and various bank deposits that function as money in the economy. For the most recent breakdown, see the Federal Reserve's official release on money measures here.
Physical currency in circulation, including Federal Reserve notes and coins, has grown steadily over the past decade. The Bureau of Engraving and Printing produces Federal Reserve notes, while the United States Mint produces circulating coins. The share of currency held abroad is significant, with the dollar serving as a global reserve currency and a trusted store of value in many economies. The Federal Reserve's Cash Product Office provides detailed data on note denominations and printing orders here.
M1 and M2 Money Supply Components
What Is Included in M1
M1 is the narrowest measure of US money in circulation and includes physical currency, demand deposits at commercial banks, and other checkable deposits. Traveler's checks were once part of M1 but now play a negligible role. M1 reflects the most liquid assets that households and businesses can use directly for transactions. The Federal Reserve's Financial Accounts of the United States provide detailed tables on M1 components here.
What Is Included in M2
M2 expands on M1 by adding savings deposits, small time deposits under 100 thousand dollars, and retail money market fund shares. These components represent funds that are still relatively liquid but not as immediately accessible as M1. M2 is widely watched as a broader gauge of the money available in the economy for spending and saving.

Key Institutions and Trends Shaping US Money in Circulation
Role of the Federal Reserve
The Federal Reserve controls the supply of base money through open market operations, the discount rate, and reserve requirements. By buying or selling government securities, the Fed influences bank reserves and, indirectly, the broader money supply measured in M1 and M2. During periods of economic stress, the Fed has expanded its balance sheet to support liquidity, which can affect the growth rate of US money in circulation. The Fed's Monetary Policy Report to Congress provides analysis of these dynamics here.
Impact of Digital Payments and Banking
The rise of digital payments, mobile banking, and fintech platforms has changed how people hold and move money, even as physical currency in circulation continues to grow. Demand deposits and electronic money now dominate everyday transactions, while cash remains important for informal economies and as a backup during disruptions.
