What Does a “75% Chance of a Rate Hike” on FedWatch Mean, and Why Does Bitcoin React in Advance?

A “75% chance of a rate hike” is neither a Fed forecast nor an analyst poll. It is a translation of fed funds futures prices. CME FedWatch looks at the average rate the market is pricing for the month of a meeting and converts the gap versus the current rate into the probability of a 25 bp move. Bitcoin reacts when those prices change, because expectations are already embedded in them long before the decision.

What happened on September 24, 2026?#

According to Yahoo Finance, Bitcoin opened at $84,370, down 2.1% from the previous day, and traded at $83,462 by 7:33 a.m. ET. Ether fell 2.5% to $2,647. The trigger was rising hike expectations: CME FedWatch showed a 75.3% chance of a hike in October and 58.6% for another one in December. The Fed calendar lists the next meetings on October 27–28 and December 8–9.

How does FedWatch turn a futures price into a probability?#

The inputs are 30-Day Fed Funds futures. Their price reflects the expected average effective fed funds rate for the month: rate = 100 − price. A contract at 96.25 implies 3.75%.

Meetings usually fall mid-month, so part of the month runs at the old rate and part at the new one. CME's methodology uses adjacent months to isolate the expected change around the meeting, then divides it by a 25 bp step. As Coinpaper illustrates, a priced move of 0.15 pp gives 0.15 / 0.25 = 0.6, a 60% chance of a 25 bp hike. For several meetings in a row the tool builds a probability tree.

Why is 75% not a Fed forecast?#

A FedWatch probability is the price at which traders are willing to hold futures, not the Fed's own view. A 75% reading means roughly 0.19 pp out of a possible 0.25 pp is priced in. These numbers move fast: per Coinpaper, after Fed Chair Kevin Warsh's Jackson Hole remarks, the odds of a September hike jumped from about 35% to 60.4%.

Why does Bitcoin move before the decision rather than after?#

By meeting day the expected outcome is usually already priced into futures, bonds and the dollar. The move happens when expectations change: after inflation data, Fed speeches or bond auctions. A higher expected policy rate lifts the yield on risk-free assets and the cost of borrowing, which reduces appetite for leveraged risk positions. When the decision matches expectations, the reaction on the day is often smaller than on the days the odds are repriced.

How should you read FedWatch without over-interpreting it?#

• Watch the change over a day or a week, not just the level: a jump from 40% to 75% is news, a steady 75% is not.
• Compare the next meeting with the one after it: 75.3% in October and 58.6% in December describe different rate paths.
• Check what moved expectations: an inflation report, a speech or the bond market. The cause matters more than the number.

What are the limitations?#

FedWatch assumes the rate moves in 25 bp steps and does not separate expectations from the risk premium: hedgers may pay up for protection against hikes, making the probability look higher than true expectations. Futures track the average effective rate, which can differ slightly from the target range. Bitcoin's link to rates is also unstable: in the year to September 24 Bitcoin lost 24.7%, and not every move is about Fed policy. No probability tells you where Bitcoin will go — it only shows which expectations are already priced in.
