In the United States, the “federal money system” is best understood as shorthand for the national monetary framework: the laws, institutions, forms of money, and payment arrangements through which the federal government and the Federal Reserve System issue currency, influence money and credit conditions, and support dollar payments. The phrase is not a formal statutory name with a single legal definition. This explanation is a descriptive definition, and it is built from the official measures, institutional roles, and policy framework that the Federal Reserve and other federal bodies publish.
What counts as “money” in official measures
The most common mistake in defining the system is treating money as if it were only paper notes and coins. The Federal Reserve defines the money supply more broadly as cash, coins, and bank-account balances in circulation. It publishes several measures, and they are not interchangeable:

| Measure | What it includes |
|---|---|
| Monetary base | Currency in circulation plus reserve balances held at the Federal Reserve |
| M1 | Currency held by the public plus transaction deposits |
| M2 | M1 plus certain small-denomination time deposits and retail money market fund shares |
The Federal Reserve’s H.6 “Money Stock Measures” release, dated August 25, 2026, sets out the current component definitions. This article does not list dollar totals. Totals change with each release, so check the most recent H.6 publication for current figures.
The institutions and who does what
The system divides responsibilities among several bodies. Each one controls a different part of the chain, from the legal rules to the physical notes in a wallet.
#1 Best Overall
| Institution | Role in the framework |
|---|---|
| Congress | Establishes the statutory framework and the long-run monetary-policy objectives |
| Federal Reserve System | The central bank; conducts monetary policy, supervises and regulates financial institutions, promotes financial-system stability, and supports payment and settlement services |
| Federal Reserve Board | Determines how many new Federal Reserve notes are needed and orders them |
| Treasury’s Bureau of Engraving and Printing | Physically prints Federal Reserve notes to the Board’s order |
| U.S. Mint | The issuing authority for coins |
| Federal Reserve Banks | Distribute notes and coin to depository institutions |
| Depository institutions | Hold the deposits counted in money measures and receive notes and coin from the Reserve Banks |
The Federal Reserve as central bank
The Federal Reserve Board’s own description of the system is direct: “The Federal Reserve System, often referred to as the Federal Reserve or simply ‘the Fed,’ is the central bank of the United States.” The Fed’s responsibilities go well beyond setting interest rates or printing cash. Its stated roles include conducting monetary policy, supervising and regulating financial institutions, promoting the stability of the financial system, and providing services that keep payments and settlements moving.
How physical money enters circulation
Notes and coins follow a different path from the policy decisions above, and the agencies involved are not the same. For Federal Reserve notes, the sequence runs as follows:
Rank #2
- The Federal Reserve Board determines how many new Federal Reserve notes are needed.
- The Board orders those notes from Treasury’s Bureau of Engraving and Printing, which does the printing. The Federal Reserve does not print the notes itself.
- The Federal Reserve Banks distribute the notes to depository institutions, which make them available to the public.
Coins follow a parallel route. The U.S. Mint is the issuing authority for coins, and the Federal Reserve Banks distribute them to depository institutions.

The Federal Reserve’s currency and coin services page reports that more than 99 percent of U.S. currency in circulation is in the form of Federal Reserve notes. That figure appears on a page last updated February 3, 2017, so it describes the composition as of that date rather than a current estimate. The remainder includes United States notes, national bank notes, and silver certificates, which remain legal tender.
Deposits and reserves: most measured money is not cash
Bank deposits are central to the system. Deposits at private depository institutions are included in the standard money measures, M1 and M2, so a large share of the money people use for payments is a bank balance rather than physical currency. The monetary base is a separate measure. It combines currency in circulation with reserve balances that depository institutions hold at the Federal Reserve. For that reason, the Federal Reserve is not the sole source of all money in the economy.
How monetary policy is governed
The framework separates what Congress decides from what the Federal Reserve decides day to day.
Rank #4
Statutory objectives set by Congress
Congress establishes the legal framework that determines how monetary policy is conducted, including its long-run objectives of maximum employment and stable prices.
Recommended Free Tools
Operational independence within accountability
The Federal Reserve carries out monetary policy with significant operational independence and is subject to transparency and accountability mechanisms. Operational independence means the Fed makes policy decisions within the statutory framework without day-to-day direction from elected officials. It does not mean freedom from the law or from public oversight.

What sits outside the monetary framework
The federal money system is not the same as federal fiscal policy. Taxing, spending, and borrowing are fiscal decisions, and they are separate from the monetary tools described here. This article does not cover fiscal policy in detail.
