Market odds diverge on Fed rate hike as Bitcoin slips below $82,000

Polymarket placed the odds of a 25-basis-point rate increase at roughly 23%, with $43 million in contracts traded. By contrast, CME’s FedWatch tool priced the probability between 37% and 44%. The disparity emerged after the latest consumer-price data showed inflation running hotter than analysts had forecast.

Inflation data reshapes expectations

The September CPI rose 3.7% year-over-year, outpacing the 3.6% consensus, while core inflation climbed 0.3% month-over-month versus a 0.2% estimate. Gasoline prices surged 9.1% over the month. Those figures lifted the FedWatch odds from about 22% before the release to a range of 37%-44% on Wednesday. Polymarket’s pricing moved more modestly, edging up from 20% to 24%.

Immediate impact on Bitcoin and Ether

Higher rate-hike expectations can raise financing costs and reduce liquidity, which tends to hurt assets without cash-flow yields. Bitcoin briefly slipped below the $82,000 mark, while Ether fell roughly 3% to near $2,430. Polymarket’s contract for Bitcoin reaching $85,000 dropped from 83% to 63% probability, and the chance of a dip to $77,500 rose to 37%.

Outlook for the October meeting

The Federal Reserve’s next gathering is set for Oct. 27-28. The decision sits six days before the November 3 midterm elections, prompting some analysts to suggest a hold could be politically sensitive. UBS described an October move as “politically untenable,” while other commentators see a hike as possible. Polymarket priced a December hike at 79%, indicating that even if the Fed pauses in October, markets still anticipate tighter policy later in the year.

Why it matters

The split between Polymarket and CME reflects how quickly market sentiment can shift in response to macro data. For cryptocurrency investors, the correlation between rate-hike odds and price pressure underscores the importance of monitoring monetary-policy indicators. A delayed or smaller-than-expected hike could provide short-term relief, but lingering expectations of future tightening may continue to limit upside for risk-on assets like Bitcoin and Ether.
