US inflation surprise lifts rate-hike odds, pressures Bitcoin

Bitcoin fell to an intraday low of $81,588.88 on 14 October after US inflation data prompted traders to price in a sharply higher chance of another Federal Reserve rate increase this month. According to market-data provider LSEG, money markets moved to imply roughly a 47% probability of an October hike, up from about 20% before the release.

The Bureau of Labor Statistics reported that September consumer prices rose 3.7% year on year, up from 3.4% in August, while annual core inflation, which excludes food and energy, accelerated to 2.6% from 2.4%. Both readings exceeded forecasts of 3.6% and 2.5%. On a seasonally adjusted monthly basis, headline CPI rose 0.6% after 0.4% in August, with gasoline prices up 9.1% and accounting for more than half the increase; shelter costs rose 0.4%. Monthly core CPI rose 0.3%, matching August but above the 0.2% forecast.

The Fed had already raised its target range by a quarter percentage point to 3.75%–4.00% on 16 September, and its next policy meeting is scheduled for 27–28 October. Post-CPI reports put the two-year Treasury yield at 4.872%, up seven basis points on the day, with the dollar gaining against a basket of currencies. The moves suggest the inflation surprise is shifting expectations for borrowing costs ahead of the Fed's decision.

For Bitcoin holders, the effect depends in part on whether higher yields persist. Continued competition from interest-bearing dollar assets could weigh on a cryptocurrency that pays no interest, even if the Fed leaves rates unchanged this month. The data followed a period of cheaper short-term volatility pricing: on 12 October, Deribit showed concentrated put options at $76,000–$80,000 for the 16 October expiry, which buyers can use to hedge against falling prices.

The immediate shift is greater market concern about further tightening. It remains unclear whether Bitcoin can withstand that pressure if yields stay elevated as the October Fed decision approaches.
