Fed Hike Odds Rise to 83% as Bitcoin Correlation Hits Record
finance.yahoo.com reports that Polymarket now prices an 83% probability of a September 16 Federal Reserve rate hike, up from 30% before the Jackson Hole symposium. This shift follows a hotter-than-expected core CPI print of 0.3% in August, which suggests underlying price pressure remains sticky. Barclays reversed its forecast on August 31 to call for consecutive 25 basis point hikes, driving prediction markets to double their odds over the past month.
Bitcoin’s correlation to rate-sensitive assets has reached a record high, meaning a Fed move will impact crypto faster than in previous cycles. The 10-year Treasury yield hit 4.95% on September 10, indicating that bonds are trading the hike before it occurs. Bitcoin trades at $77,293.66, while XRP sits at $1.37, with both assets having held their levels despite the yield jump.
An 83% priced-in hike implies a delivered move may produce only a modest reaction, whereas an 18% hold scenario carries the biggest surprise potential. Chair Kevin Warsh’s Fed has held rates at a 3.75% upper bound since December 2025, and a hike would end that five-meeting streak.
