U.S. inflation accelerated in September, prompting an immediate selloff in Bitcoin and government bonds as traders reassessed the chance of another Federal Reserve interest-rate increase. The Consumer Price Index rose 0.6% from August on a seasonally adjusted basis and 3.7% over the prior 12 months, the Bureau of Labor Statistics said Wednesday. The annual rate was up from 3.4% in August and exceeded the 3.6% consensus estimate reported by Associated Press and CoinDesk.

Gasoline drove the headline increase

Energy was the main source of the monthly acceleration. The gasoline index climbed 9.1% and accounted for more than half of the all-items increase, while the broader energy index rose 5.2%. Shelter increased 0.4%. Food prices were unchanged overall, with a 0.1% decline in food at home offsetting a 0.2% increase in food away from home. Those details matter because they show that a large part of the headline move came from fuel, even as other categories continued to rise.

Core inflation also exceeded forecasts

The index excluding food and energy increased 0.3% for the month, matching August's pace but exceeding the 0.2% consensus forecast cited by CoinDesk. Core CPI was 2.6% higher than a year earlier, compared with 2.4% in August and a 2.5% estimate. Recreation, used vehicles, education, airline fares, medical care and apparel were among the categories that increased. Communication was one of the relatively few major indexes to decline.

Bitcoin and bonds reacted within minutes

CoinDesk reported that Bitcoin dropped roughly $1,000 after the 8:30 a.m. Eastern release, trading near $82,800 shortly afterward. The two-year Treasury yield rose about 13 basis points to 4.924%, while the 10-year yield gained roughly 9 basis points to 5.308%. Associated Press later reported the 10-year yield at 5.28%, up from below 5.17% immediately before the data. These observations capture a fast market reaction rather than a fixed closing price; cryptocurrencies and bond yields can reverse as trading continues.

Why the report matters for crypto

Higher inflation can keep borrowing costs and Treasury yields elevated, increasing the appeal of interest-bearing assets relative to riskier holdings. It can also support the dollar and reduce expectations for easier monetary policy, conditions that often pressure Bitcoin and other digital assets in the short term. The connection is not mechanical, however. Crypto prices also respond to fund flows, leverage, regulation, company news and broader risk appetite, so one inflation release cannot explain every market move or establish a lasting direction.

The Fed decision remains open

Associated Press said traders moved to roughly even odds of a rate increase at the Fed's next meeting, up from about 22% a day earlier. That pricing is a market estimate, not an official signal. Policymakers will weigh additional labor, growth and inflation evidence before deciding whether to change rates. They will also need to judge whether the gasoline shock is temporary or is beginning to influence a broader set of prices and expectations. September's report strengthens the case for caution because both headline and core readings exceeded annual forecasts, but it does not guarantee another increase. One month of data can be revised or followed by a different pattern. For households, the immediate facts are more concrete: fuel and shelter costs rose, headline inflation accelerated, and financial markets repriced the path of U.S. interest rates.
