How Fed decisions move markets: expectations, surprises and yields

Every few weeks the FOMC announces a decision at 2:00 p.m. Eastern, and markets move. But they rarely move the way a newcomer expects. A rate cut can send bond yields up; a hike can lift stocks; a decision that changes nothing can be the most market-moving event of the month. The reason is simple: prices already reflect what traders expect the Fed to do. What moves markets is the difference between what happened and what was expected, and above all what the decision says about the path of rates over the next year or two.

This guide explains how that expectation is formed and measured, from fed funds futures to the 2-year Treasury yield, walks through a worked example of reading a futures price, and uses monthly data from 2015 to 2026 to show the 2-year yield moving months before the Fed did. How rates then feed into stock valuations is covered in How interest rates affect stocks: discount rates and equity duration; this page is about the step before that, how a Fed decision becomes a change in rates at all.

Priced in: why expected decisions move little

Think of a 2-year Treasury note. An investor can buy it, or roll overnight money for two years at whatever the fed funds rate turns out to be. If the two strategies are expected to pay about the same, the 2-year yield must roughly equal the average expected policy rate over the next two years, plus a small premium for locking money up. So the 2-year yield moves whenever the expected path moves, which happens every time new data or Fed communication change the outlook, not just on decision days.

By the morning of a meeting, the decision is usually well understood. If traders are nearly certain of a 25 bp cut and they get one, the path has not changed and neither have yields. If they expected a cut and the committee holds, the whole path shifts up, and short-term yields jump.

Measuring expectations: fed funds futures

The most direct gauge is the 30-Day Federal Funds futures contract listed by CME Group. Each contract covers one calendar month and is cash-settled against the average of the daily effective fed funds rates the New York Fed publishes that month. It is quoted as an index:

Futures on the Secured Overnight Financing Rate (SOFR) and options on both contracts extend the same idea further out in time, and short-dated Treasury bills and notes carry the same information in their yields.

The 2-year yield leads the Fed

The chart shows the same pattern in every turn of the cycle since 2015: the 2-year yield moves first, and the policy rate follows.

In early 2022 the 2-year yield had risen more than a full percentage point before the Fed raised rates at all; by October 2022 it averaged 4.38%, above the top of the range (3.25%), as markets priced further hikes. In 2024 the 2-year had fallen 0.9 points from its April level by August, a month before the first cut. In 2026 it rose 0.75 points from February to July, two months before the September hike, and averaged 4.65% in September. By the time each decision arrived, much of it was in the price.

After the decision: the rest of the curve

The policy rate moves short-term yields almost one for one. Longer yields respond to the whole expected path, to inflation expectations and to a term premium, so they can go the other way.

The same split appeared in 2026. Between February and September 2026 the 3-month bill yield rose 0.34 points, the 2-year 1.18 points and the 10-year 0.86 points, to 4.99%, the highest monthly average since 2007. A one-step Fed hike accounted for only part of that move; the rest was repricing of the path and of longer-term rates. The data show what moved; they do not by themselves say why.

Where the surprise can come from

Data releases matter as much as meetings, because they change what the Fed is expected to do next; How markets react to economic data: surprises, regimes, revisions covers that side.

Pitfalls

• "The Fed cut, so yields will fall." Only the very short end is tied to the decision. Longer yields depend on the expected path and on inflation; in late 2024 they rose through a series of cuts.
• Reading the first five minutes. Statement and press-conference reactions often differ. Wait for the press conference before drawing conclusions.
• Ignoring what was priced. A 25 bp move with 95% implied odds is not news; the same move with 40% odds is.
• Treating futures odds as forecasts. Implied probabilities include risk premiums and change daily with data.
• Over-reading one meeting. The Fed's strategy statement stresses that policy acts with lags. Markets look through single meetings to the path.

How Finabase does it

Finabase does not show fed funds futures, implied probabilities, an FOMC calendar or Fed rate data; the chart and tables on this page are ours, built by Finabase Research from Federal Reserve data on FRED. The app does carry the markets that react to the Fed:

• The Treasury yields table, with the 1-month and 3-month bills and the 2-year, 10-year and 30-year yields, so you can see how far up the curve a surprise travels.
• The futures list, with Treasury futures (including the 2-year and 10-year) beside stock-index futures, which trade nearly around the clock.
• Exchange rates on the forex page, such as EUR/USD, for the dollar's reaction.
• Fed news on Discover for coverage of each decision.

Frequently asked questions

Why do markets move before the Fed acts?

Because prices reflect expected policy. Traders in futures and short-term Treasuries price each meeting in advance; once a move is expected, it is already in yields, so the decision itself adds little unless it differs from expectations.

What does "priced in" mean for a Fed decision?

It means current market prices already assume the decision. In fed funds futures, a fully priced 25 bp cut is one where the implied rate for the months after the meeting already sits about 25 bp lower.

Why did long-term yields rise when the Fed cut rates in 2024?

The data show the 10-year yield rising from 3.72% to 4.39% between September and December 2024 while the Fed cut. Long yields reflect the expected path of rates over many years plus inflation expectations and a term premium; when markets revise those up, long yields can rise even as the policy rate falls.

Which market reacts most to Fed surprises?

Short-dated Treasuries, especially the 2-year note, and fed funds futures react most directly, followed by the dollar. Stocks react through yields and the growth outlook; see the guide on how interest rates affect stocks.

Summary

Fed decisions move markets through expectations. Prices already reflect the expected path of the fed funds rate, measured directly by fed funds futures (100 minus the expected average rate) and indirectly by short-term Treasury yields, so markets react to the surprise in the decision, the vote, the wording, the dot plot or the press conference, not to the decision itself. From 2015 to 2026 the 2-year yield moved months before every turn in policy: it rose more than a point before the March 2022 hike, fell ahead of the 2024 cuts and rose ahead of the September 2026 hike. Longer yields follow their own logic and can move against the policy rate, as they did in late 2024. Watch the front end of the curve to see what the market thinks the Fed will do.
