Bitcoin slipped below $82,000 on October 14 after US inflation data came in hotter than expected, pushing market expectations for another Federal Reserve rate increase to roughly 47%. The Bureau of Labor Statistics reported that consumer prices rose 3.7% annually in September, up from 3.4% in August, with core inflation climbing to 2.6% from 2.4%. Both figures exceeded forecasts of 3.6% and 2.5%, respectively. On a monthly basis, headline CPI increased 0.6%, driven largely by a 9.1% jump in gasoline prices, while shelter costs rose 0.4%. The two-year Treasury yield climbed to 4.872%, and the dollar strengthened against major currencies. Market analysts noted that higher yields could make interest-bearing dollar assets more attractive than Bitcoin, which does not generate interest. The shift in financial markets reflected growing concern about the pace of monetary tightening ahead of the Fed's October 27-28 policy meeting. Bitcoin had previously reached an intraday low of $81,588.88 following the data release. Earlier in October, the Fed had raised its target rate range to 3.75%-4.00% on September 16, and another increase would extend that tightening cycle. Some investors had previously positioned for lower prices using put options on Deribit, with contracts tied to $76,000-$80,000 expirations on October 16. The evolving interest rate outlook continues to influence Bitcoin's price trajectory, particularly as higher yields may sustain pressure on the cryptocurrency even if rates remain unchanged in the near term.
