Traders Split on Fed's Next Rate Move as Odds Flip Rapidly
Markets now favor another hike by December after a dramatic shift in expectations.
1Dramatic odds reversal
In just one month, market expectations for Fed policy flipped completely. Where traders previously saw a 53.6% chance of an October rate cut, they now assign 0% probability to that outcome. Instead, prediction markets give a 57.6% chance of another quarter-point hike at the October meeting. This reversal followed the Fed's first rate increase in 1,148 days on September 16, which moved the target range to 3.75%-4%.
2Three markets converge
Polymarket, Kalshi, and CME futures all show remarkably similar expectations despite different trading mechanisms. Polymarket gives 56% odds to an October hike, Kalshi 54%, and CME 57.6%. The consistency across these markets suggests strong consensus among traders. More than $7.7 million has traded on these contracts since June, with Kalshi's October market alone seeing $1.93 million in volume as of September 19.
3Chair's deliberate ambiguity
Fed Chair Kevin Warsh explicitly refused to provide forward guidance after the September hike. When asked about potential rate hike sequences, he stated 'I'm not in the forward guidance business' and emphasized data dependence. Warsh dismissed focusing on individual economic releases, calling such dependence 'a dangerous preoccupation.' This stance leaves traders guessing without clear policy signals from the central bank itself.
4Inflation remains key driver
The Fed's September decision cited inflation persistently above its 2% target. Warsh noted August PCE inflation at 3.6% annually, with core PCE at 3.2%. He emphasized inflation has been 'too high for too long,' marking five consecutive years above target. These comments help explain why markets now expect more tightening despite Warsh's refusal to telegraph future moves.
5December's clearer outlook
While October remains uncertain, December expectations show stronger conviction. CME futures assign a 90.1% probability that rates will exceed the current 3.75%-4% range after the December meeting. Nearly half this probability (44.1%) points to rates reaching 4.25%-4.5%, suggesting traders anticipate two more quarter-point hikes by year-end.
6Political pressure mounts
President Trump publicly criticized the September hike, demanding rates be slashed to 1% or below. While maintaining confidence in his appointee Warsh, Trump attacked other Fed board members as 'very political' and 'hostile.' This creates unusual tension as the Fed weighs economic data against political pressure ahead of its October decision.
7Market structure insights
Prediction markets reveal nuanced expectations through their probability distributions. For December, CME futures show 46% probability for 4%-4.25% rates and 44.1% for 4.25%-4.5%. This two-hike scenario carried just 2.6% probability a month ago. The steep shift suggests traders now see September's move as potentially starting a tightening cycle rather than being isolated.
8Historical context matters
The 1,148-day gap between rate hikes was the longest since the 2008 crisis. Markets now bet the next hike could come in just 42 days. This rapid potential tightening reflects how inflation concerns have overtaken earlier growth worries. The speed of changing expectations underscores how quickly macroeconomic narratives can shift in modern markets.
