What is the Federal Reserve (the Fed)?

The Federal Reserve — "the Fed" — is the central bank of the United States. It sets US interest rates, manages the supply of dollars, and works to keep the economy stable. Because the dollar is the world's reserve currency and sits on one side of most forex pairs, no institution moves the currency market more than the Fed.

What does the Fed actually do?

The Fed operates on a dual mandate set by Congress: maximum employment and stable prices, with an inflation target of 2%. To steer between them it adjusts the federal funds rate — the benchmark US interest rate — and, in extraordinary times, buys or sells bonds to add or drain money from the system. Every other tool serves those two goals.

That dual mandate is worth dwelling on, because it is unusual. The ECB is an inflation-first institution by design; the Fed is legally required to weigh jobs as well. In practice this means US employment data moves the dollar in a way that equivalent European data does not move the euro — a weak payrolls report is not just economic news, it is a direct argument for cuts.

Why is it called a "system"?

Because it is not one building. The Federal Reserve System has three parts, and headlines blur them constantly:

• The Board of Governors — seven governors in Washington, including the Chair, appointed by the President and confirmed by the Senate. This is the federal, public half.
• Twelve regional Reserve Banks — New York, Chicago, Dallas and nine others, each covering a district and each with its own president. The New York Fed is the important one for markets, because it runs the desk that actually executes policy.
• The FOMC — the committee where the two halves meet to set rates. It is the twelve members with a vote at any given time: the seven governors, the New York Fed president permanently, and four other regional presidents who rotate.

That structure is why you will hear conflicting opinions from "the Fed" in the same week. A regional president giving a speech is expressing a view, not announcing policy. Only the FOMC decides.

Who decides, and when?

Rate decisions are made by the FOMC, the Federal Open Market Committee, which meets eight times a year. Each meeting ends with a rate decision, a statement, and — four times a year — economic projections including the "dot plot" of where members expect rates to go. The Chair's press conference afterwards often moves markets more than the decision itself.

Two documents keep moving the dollar after the day is over. The minutes arrive three weeks later and reveal how divided the committee was — a unanimous hold and a narrow one are different signals about the next meeting. And in the weeks before each meeting the Fed enters a blackout period, when officials stop commenting publicly; the silence itself removes a source of volatility, which is why positioning often builds quietly through it.

Why does it move forex?

When the Fed raises rates, dollar assets pay more, foreign capital flows in to capture the yield, and the dollar tends to strengthen — pushing EUR/USD down, USD/JPY up, and so on. When it cuts, the reverse. Traders don't just react to the decision; they trade the expectation of it for weeks beforehand, which is why Fed speakers and US inflation data swing pairs long before a meeting.

Put it in numbers. Say the market has 40 basis points of cuts priced for the year and the dot plot then shows members expecting only 25. Nothing was cut, nothing was hiked — but the expected path just moved 15 basis points in the dollar's favour, and every dollar pair reprices in seconds. That is the mechanism: the Fed trades in expectations, and the decision is usually the least surprising part of the meeting.

Hawkish vs dovish

A Fed leaning toward higher rates to fight inflation is "hawkish" (dollar-positive); one leaning toward cuts to support growth is "dovish" (dollar-negative). Reading whether the latest statement tilted hawkish or dovish is one of the most valuable skills in macro trading.

The tell is rarely the rate. It is the changed words in the statement — the Fed edits the previous version rather than writing a new one, so a dropped sentence or an upgraded adjective is a deliberate signal. It is also the dot plot's median, and, on the day, the Chair's answer to the first question about cuts.

The Fed vs the rest

The Fed is one of several major central banks — alongside the ECB, the Bank of Japan, and the Bank of England — but its reach is unique because so much global trade, debt, and reserves are priced in dollars. When the Fed tightens, the ripple hits currencies, bonds, and stocks worldwide, not just the US.

The asymmetry is the point. A hawkish Fed tightens financial conditions in countries that had no say in the decision, because their companies borrowed in dollars and their commodities are priced in dollars. No other central bank exports its policy that way.

What traders get wrong on Fed day

Treating the decision as the event. The rate is usually priced. The statement wording, the dot plot and the press conference are where the repricing happens.

Reading a cut as automatically dollar-negative. A cut delivered alongside a hawkish message about the pace of future cuts regularly sends the dollar higher.

Confusing a speech with policy. A regional president is one voice among nineteen and may not even have a vote that year.

Forgetting the other side of the pair. USD/JPY is a Fed story and a Bank of Japan story, and in some years the second one is louder.

The takeaway

Treat the Fed as the gravitational center of the forex market. Know the date of the next FOMC meeting, whether inflation is pushing the Fed hawkish or dovish, and how the market is already positioned — and you understand most of what's driving the dollar on any given day.
