Few events move markets like a Federal Reserve interest rate decision. Yet the decision is rarely a surprise. To understand why stocks and bonds still react so strongly, you need to know how the Fed makes these decisions and what investors are really listening for.

What the FOMC is

The Federal Open Market Committee (FOMC) is the Fed’s monetary policy body. It has 12 voting members:

  • the seven members of the Board of Governors in Washington, including the Chair;
  • the president of the Federal Reserve Bank of New York, who always votes;
  • four of the other eleven regional Reserve Bank presidents, who vote on a rotating basis.

All twelve Reserve Bank presidents attend meetings and join the discussion, even in years when they do not vote.

The dual mandate

Congress has given the Fed two goals: maximum employment and stable prices, along with moderate long-term interest rates. The Fed defines price stability as inflation of 2% over the longer run, measured by the personal consumption expenditures (PCE) price index. That is why the PCE report gets so much attention; see CPI vs. PCE.

The two goals can conflict. When inflation is high and the job market is weak, the Fed must decide which risk matters more.

How rate decisions work

The FOMC holds eight scheduled meetings a year, roughly every six weeks, and can meet in between if needed. At each meeting it sets a target range for the federal funds rate, the rate banks charge each other for overnight loans. The Fed steers the actual rate into that range mainly by setting the interest it pays on reserve balances banks hold at the Fed and through its overnight reverse repurchase facility.

Changes in the federal funds rate ripple through the economy, affecting rates on credit cards, business loans, and, less directly, mortgages and bond yields. For the market effects, read how interest rates move the stock market.

The balance sheet

The Fed’s other major tool is its balance sheet. Buying large amounts of Treasury and mortgage-backed securities, often called quantitative easing, pushes longer-term interest rates down. Letting those holdings shrink, called quantitative tightening, works in the opposite direction.

Decision day: what markets watch

  1. The decision: released at 2:00 p.m. Eastern Time. Futures markets usually price in the outcome in advance, so the decision alone rarely surprises.
  2. The statement: small wording changes can signal where policy is heading.
  3. The projections: four times a year, the Fed publishes the Summary of Economic Projections, including the “dot plot.” See how to read the dot plot.
  4. The press conference: the Chair takes questions about 30 minutes after the statement. Markets often swing during the answers.
  5. The minutes: released three weeks later, they reveal the range of views in the room.

Why a “no change” can move markets

Markets trade on the expected path of rates, not just today’s rate. If the Fed holds steady but signals fewer cuts than investors expected, yields can rise and stocks fall. The key question is always how the decision and guidance compare with what was already priced in.
