How FOMC Decisions Move the US Dollar
The decision is usually priced in. What moves the dollar is the statement, the dots and the press conference, and the rate path they imply.
What the FOMC actually decides
The Federal Open Market Committee sets the target range for the federal funds rate and meets eight times a year. The decision is published at 2:00 p.m. Eastern, followed by a policy statement. Half an hour later the chair takes questions, and four times a year the meeting also publishes the Summary of Economic Projections, including the dot plot of participants' rate expectations.
For the dollar, the decision itself is rarely the event. By the time the committee meets, fed funds futures have usually priced the outcome almost completely, so a decision in line with expectations carries very little information. What moves the currency is the part of the meeting that changes the expected path: the wording of the statement, the projections, and the chair's answers.
The dollar is a relative price. It trades against a basket of currencies and, more importantly, against the expected policy paths of other central banks. A hold delivered with hawkish guidance can lift the dollar as much as a hike, and a cut delivered with a signal that easing is finished can do the same. The currency is a forward-looking instrument, so it discounts the next two years of policy rather than today's level.
The transmission chain
- The decision and the statement. The rate is compared with what was priced. The statement is compared word by word with the previous one, and deleted hedges or changed adjectives often matter more than the rate.
- The expected path. Fed funds futures and the OIS curve reprice. The market is not asking what the rate is today but where it will be in a year.
- Front-end yields and rate differentials. The two-year Treasury yield and its equivalents abroad set the carry advantage of holding one currency over another.
- The dollar. Higher expected US rates relative to peers typically support the dollar; the reverse weakens it. The dollar index, EUR/USD and USD/JPY are the fastest reads on whether the move is broad or pair-specific.
- Risk appetite as a second channel. A hawkish surprise can tighten financial conditions and raise demand for dollar liquidity, reinforcing the rate channel. A dovish surprise can do the opposite.
How it usually trades around the meeting
Into the meeting, volatility in currency options typically falls and spot drifts, because dealers and funds avoid carrying risk through the announcement. Positioning is often already tilted toward the consensus outcome, which matters for the reaction more than the outcome itself does.
At 2:00 p.m., the statement produces a fast repricing in the front end and an immediate dollar move. In the first minutes the move can be exaggerated by thin liquidity and by algorithms parsing the text. The 2:30 press conference is frequently the larger event: a chair who sounds more concerned about inflation than the statement suggested can reverse the initial move entirely.
After the meeting, the question is whether the repricing holds. A dollar move that survives into the next session and is confirmed by a shift in the two-year yield and in fed funds futures reflects a genuine change in expectations. A move that fades before the London open was usually a positioning event, not a macro one.
Three common misreadings
Treating the rate decision as the event
Most decisions are fully priced. The information sits in the guidance and the projections. Trading the headline decision means trading something the market already knew, which explains why so many in-line meetings produce the largest moves.
Assuming a cut is always bearish for the dollar
It depends on why the Fed is cutting and on what else is priced. Cuts delivered because inflation is falling, while other central banks ease faster, can coexist with a firm dollar. Cuts delivered into a recession usually weaken it, but often with a delay and through the risk channel rather than the rate channel.
Ignoring the dots and the press conference
The median dot and the dispersion around it show how divided the committee is, and the Q&A is where the chair clarifies what the statement left ambiguous. Both can move the dollar more than the decision, especially in a meeting where the rate itself was a foregone conclusion.
What to watch
- The statement compared with the previous one: which sentences were added, which were removed.
- The median dot against market pricing, and the spread of the dots around that median.
- The two-year Treasury yield, the cleanest single read on expected policy.
- Fed funds futures before and after, to see whether the path actually moved.
- The press conference, especially any characterisation of inflation risk and labour market risk.
- Relative policy: what the ECB, the Bank of Japan and others are doing at the same time.
