How the Fed Sets Interest Rates—the FOMC Explained

Twelve Votes That Move the World

Eight times a year, a dozen people sit around a mahogany table in Washington, D.C., and decide the price of money. The Federal Open Market Committee (FOMC) is the body inside the U.S. Federal Reserve that sets the target range for the federal funds rate—the overnight interest rate at which banks lend reserves to one another. That single number cascades through mortgage rates, car loans, corporate bonds, and currency markets worldwide.

Who Sits at the Table

The FOMC has 12 voting members drawn from two pools. The first pool is permanent: all seven governors of the Federal Reserve Board, nominated by the president and confirmed by the Senate, plus the president of the Federal Reserve Bank of New York, who holds a permanent seat because the New York Fed executes the committee's market operations.

The remaining four votes rotate among the presidents of the other 11 regional Reserve Banks. They are divided into four groups, and within each group the presidents take turns serving one-year voting terms. The Cleveland and Chicago Fed presidents rotate on a two-year cycle; all others rotate every three years. Non-voting presidents still attend every meeting, participate in discussions, and submit economic projections—they simply cannot cast a formal vote.

Inside the Meeting

Each FOMC meeting spans roughly two days. Staff economists open with a briefing on financial markets, domestic economic conditions, and the international outlook. Regional Fed presidents then share intelligence gathered from business contacts in their districts—anecdotal data that often captures shifts before official statistics do.

After discussion, the chair proposes a policy action—typically to raise, lower, or hold the target rate range steady. Members vote, and the result is announced in a post-meeting statement released at 2:00 p.m. Eastern Time. The chair then holds a press conference to explain the committee's reasoning.

Dissent is permitted and publicly recorded. Historically, only about 6 percent of all FOMC votes since 1936 have been dissents, according to the Federal Reserve Bank of St. Louis. Yet dissent rates have risen in recent decades, averaging roughly 5.5 per year between 2006 and 2017 compared with about 2 per year in the prior 15-year stretch.

The Tools Behind the Target

Setting a target is one thing; hitting it is another. Before the 2007–09 financial crisis, the Fed relied mainly on open market operations—buying and selling government securities to adjust the supply of bank reserves and nudge the overnight rate toward its target.

Today the system works differently. Banks hold far more reserves than they once did, so the Fed instead steers rates primarily through interest on reserve balances (IORB). By paying banks a set rate on the funds they park at the Fed, the central bank creates a floor: no bank will lend overnight for less than it can earn risk-free. A second tool, the Overnight Reverse Repurchase Agreement (ON RRP) Facility, extends that floor to money-market funds and other non-bank institutions.

Together, IORB and ON RRP form the upper and lower boundaries of a 25-basis-point target range—for example, 3.50 % to 3.75 %—keeping the effective federal funds rate neatly inside the corridor.

Why It Matters Beyond Wall Street

Changes in the federal funds rate set off a chain reaction. When the rate rises, borrowing costs increase across the economy—mortgages become more expensive, businesses delay expansion, and consumer spending cools. When it falls, credit loosens and spending tends to accelerate. The Fed uses this lever to pursue its dual mandate: maximum employment and stable prices, targeting inflation of 2 percent over the long run.

Because U.S. Treasury yields serve as a global benchmark, FOMC decisions also influence exchange rates and capital flows worldwide. Central banks from Frankfurt to Tokyo watch the committee's every word for signals about the future path of rates—a practice so obsessive that analysts have coined the term "Fed-watching" to describe it.

The Power of Persuasion

The FOMC chair has no extra vote but wields enormous influence. The chair sets the meeting agenda, frames the policy proposal, and speaks for the committee publicly. As a result, the chair's ability to build consensus is often described as "the power of persuasion." When that consensus fractures—as it does during periods of high uncertainty—the resulting dissents offer a rare, public window into the tensions shaping the world's most consequential economic policy.
