Manages federal finances — and its most familiar public-facing arm, the IRS, is only one part of a much larger operation.
Treasury collects taxes, issues currency, manages the national debt, and enforces economic sanctions. It’s one of the original four Cabinet departments, dating to the first Washington administration.
A national debt, if it is not excessive, will be to us a national blessing.
Alexander Hamilton, First Secretary of the Treasury
What It Does
The Secretary of the Treasury is the President’s principal economic policy adviser and manages the federal government’s finances — collecting revenue, paying the government’s bills, managing the national debt through bond issuance, and producing the nation’s currency.
Collects revenue
The IRS, a Treasury bureau, administers and enforces federal tax law and collects nearly all federal revenue.
Manages the debt
The Bureau of the Fiscal Service issues and manages Treasury bonds, notes, and bills that finance federal borrowing.
Enforces sanctions
The Office of Foreign Assets Control administers economic sanctions against targeted countries, entities, and individuals.
Produces currency
The U.S. Mint and Bureau of Engraving and Printing produce the nation’s coins and paper money.
How It Fits Into Government
A department, not the central bank
The Secretary of the Treasury reports to the President and leads the department’s finance and tax functions. Congress writes tax law, sets the statutory debt limit, and appropriates Treasury’s budget. Treasury manages the government’s own borrowing and spending — but monetary policy, including interest rates, is set by the Federal Reserve, an independent central bank deliberately structured outside Treasury.

Treasury doesn’t set interest rates
A common misconception is that the Treasury Department controls interest rates or the money supply. That authority belongs to the Federal Reserve, an independent central bank deliberately insulated from day-to-day political direction. Treasury manages the government’s own borrowing and spending; the Fed sets monetary policy — two related but genuinely separate functions, often confused because both deal with the economy at a national scale.
