US Inflation Hits 3.7% in September, Reviving Odds of an October Fed Hike
October 15, 2026
A Hotter Inflation Print Puts the Fed Back in Focus
US inflation climbed faster than expected in September, and crypto markets felt it within hours. The consumer price index rose 3.7% over the 12 months to September, up from 3.4% in August, according to the Bureau of Labor Statistics. Economists had expected 3.6%. Prices rose 0.6% in the month alone. The release, published on Wednesday, revived a question many traders thought had faded: will the Federal Reserve raise interest rates again at its October 27 to 28 meeting?Energy Costs Drive the Surge
The biggest push came from energy. BLS data show energy prices up 20.4% over the year and 5.2% in September alone, the report’s sharpest component move. Shelter costs rose 3.2% annually, while food prices were flat month on month and up 2.5% year on year. Core inflation, which strips out food and energy, rose 2.6% year over year, up from 2.4% in August and above the 2.5% forecast. That matters because Fed officials watch core inflation most closely for signs that price pressure is spreading beyond fuel.
Rate Hike Odds Spike, Then Cool
Markets reacted fast. On Polymarket, odds of an October hike briefly jumped to nearly 50% after the release, then eased to about 30%, CoinDesk reported. CME’s FedWatch tool showed a similar swing, from roughly 22% to almost 47%, before settling near 26%. Even after the pullback, fed funds futures still priced more than a 70% chance of no change this month. The debate is live, not settled. The Fed raised rates to a 3.75% to 4% range in September, and in the first hike since 2023, 16 of 18 officials signalled they expected at least one more increase this year. A hot September print gives that view more weight. “Stronger U.S. inflation data has renewed concerns that interest rates will stay higher for longer,” Vikram Subburaj, CEO of Giottus, told CoinDesk.Bitcoin Slides Toward $80,000
Bitcoin fell 3.3% in 24 hours to around $80,979 after the CPI release, FXStreet reported, citing BeInCrypto. It briefly dipped near $80,000 before stalling around $81,000 on Thursday. Ether, XRP and Solana each fell roughly 3.5% to 4%, according to CoinDesk, while broader crypto market prices followed Bitcoin lower. Asian equities added to the pressure, with South Korea’s Kospi dropping 8% and triggering circuit breakers. Liquidations neared $1 billion over 24 hours, with long positions making up about 91.6% of the total. Spot Bitcoin ETFs also posted $261.5 million in net outflows on CPI day, according to SoSoValue.Why Inflation Data Moves Crypto Prices
For beginners, the link between a government price report and Bitcoin can seem distant. It runs through interest rates. The CPI tracks what a typical basket of goods and services costs each month. When it rises faster than expected, the Fed is more likely to raise rates to cool spending. Higher rates make safe assets, such as savings accounts and government bonds, pay more. That changes the maths for investors. When a low-risk bond pays a solid return, fewer people feel the need to chase higher-risk assets like crypto. Borrowing also gets more expensive, which tends to shrink leveraged trading in the market. This is why traders watch inflation days so closely. A single report can shift expectations for the Fed, and those expectations can move crypto within minutes.Key Levels Analysts Are Watching
Glassnode data cited by FXStreet places the average cost basis of US spot Bitcoin ETF buyers near $81,500, a level Bitcoin has now dropped below. The firm flags $80,000 as key support, where the largest bid block sits on Binance’s spot order book. On the upside, $88,000 marks the cost basis of buyers from the past six to 12 months, according to Glassnode. A daily close above it, paired with fresh ETF inflows, could suggest buyers are absorbing supply again. Not every signal points lower. CryptoQuant data shows whale holdings outside exchanges reached 3.03 million BTC, the highest since November 2025. “Whales have switched from selling to accumulating,” CryptoQuant CEO Ki Young Ju wrote in an October 13 report. “With the next FOMC a coin flip, this uncertainty is damaging liquidity and dampening risk appetite across all asset classes,” STS Digital’s Anderson told CoinDesk. Anderson still expects the Fed to hold this month.A Market Now Trading on Energy Prices
The September report shows how tightly crypto is now tied to the wider economy. The surprise was not in core prices, which remain modest at 2.6%, but in an energy shock that pushed the headline figure higher. That puts the Fed in a difficult position. Raising rates in response to fuel costs could tighten conditions further while the underlying trend stays contained. Holding could risk inflation expectations drifting upward. For crypto, the next two weeks may depend less on blockchain news and more on oil and the Fed’s reading of it. Traders looking for direction will likely be following the latest crypto news alongside the October 28 decision. If energy prices ease, pressure on risk assets could lift. If they keep climbing, the market may face a second hike it has only partly priced in.
