Fed October Rate Hike Odds Rise to 65% on Polymarket as Bitcoin Faces Macro Headwinds

Bitcoin and the broader cryptocurrency market are encountering renewed macroeconomic pressure as traders increasingly anticipate another Federal Reserve interest rate hike in October. According to Polymarket, the probability of a rate hike in October has risen to 65%.

This shift in market expectations follows remarks from Federal Reserve Governor Michael Barr, who indicated that further monetary tightening may be necessary to return inflation to the central bank’s 2% target.

The 10-year Treasury yield hit 5.116% today, its highest level since July 2007. This marks the largest one-day move in 18 months. PMI surveys came in significantly stronger than expected.

Simultaneously, fresh economic data indicates that the U.S. economy remains surprisingly resilient, with business activity and employment showing strength alongside persistent price pressures.

This has led to a significant repricing of expectations for the Fed’s October meeting, which could have important consequences for Bitcoin and other risk assets.

Fed October Decision Polymarket Odds: Prediction Markets Put October Hike Chances at 65%

According to Polymarket, which is tracking the decision, prediction market traders are currently assigning a 64% probability to a 25-basis-point Fed rate increase at the October 27-28 meeting.

The market assigns approximately 35% odds to no change, while the probabilities of either a larger hike or a rate cut remain below 1%. Polymarket’s market has generated more than $14 million in trading volume, providing a substantial pool of capital behind these expectations.

These figures have moved considerably as investors digest the latest inflation data and increasingly hawkish comments from Fed officials.

This makes the October meeting particularly significant for cryptocurrency investors. A further increase would push the federal funds target range above its current 3.75%-4% level, following the Fed’s rate increase in September.

What Would Another Fed Hike Mean for Bitcoin?

For crypto investors, the primary concern is liquidity. Bitcoin has increasingly traded as a macro-sensitive risk asset, meaning that changes in interest rate expectations can substantially affect demand for cryptocurrencies.

Higher interest rates can make cash and government bonds more attractive relative to speculative assets. They can also raise borrowing costs and reduce the liquidity flowing into higher-risk investments.

Nevertheless, cryptocurrencies have demonstrated considerable resilience. Bitcoin surged above $86,000 earlier this month, reaching an eight-month high, despite the Fed already raising rates by 25 basis points in September. Recent gains have been supported by stronger ETF flows, improving regulatory sentiment, and short covering.

Bitcoin was also on track for its first three-month winning streak from July through September since 2012, according to CoinDesk.

This resilience is significant because it suggests that investors are not necessarily treating higher rates as an automatic reason to abandon crypto. However, the market reaction later in the week showed that monetary policy still matters.

Bitcoin finished September 25 around $84,071, retreating from its September 21 peak as Treasury yields rose and expectations for further Fed tightening grew. Ethereum followed a similar pattern, ending the week around $2,693.
