Why is crypto down? Bitcoin fell by 4% over 24 hours, while Ethereum lost about 6.5% as hotter U.S. inflation and a technology sell-off put pressure on risk assets. The comparison sharpens a familiar market question: when rates and funding costs move back into focus, does Bitcoin trade more like a high-beta asset than a hedge?
September’s Consumer Price Index rose 0.6% from the previous month and 3.7% year over year. Core CPI, which excludes food and energy, increased 0.3% monthly and 2.6% annually, while gasoline prices jumped 9.1% and accounted for more than half of the headline monthly gain.
The readings put a possible Federal Reserve hike back on traders’ radar ahead of the October 27–28 meeting. CME FedWatch briefly showed a 31.6% implied chance of a hike on October 28, up from 22.1% a day earlier, before later pricing put the probability of the Fed staying on hold at 75%.
This swing ran riot for crypto because rate expectations influence the cost of capital and the appetite for assets whose valuations depend heavily on future growth. Bitcoin’s sensitivity to inflation releases and nearby support levels was already part of the market debate before this move.

U.S. equities weakened alongside crypto: the S&P 500 fell 1.1%, the Nasdaq Composite lost 1.9%, and a semiconductor-stock gauge extended its declines to a sixth day.
In Asia, the KOSPI plunged 8%, and the Nikkei 225 fell 4.8%, with Samsung Electronics down 9.3%, SK Hynix and Kioxia each losing more than 11%, and SoftBank sliding 9.4%.
Oracle, CoreWeave and other AI stocks were as sensitive to higher borrowing costs, while technology supply-chain shares absorbed heavy selling. Ethereum’s larger decline than Bitcoin’s is consistent with greater weakness in higher-beta crypto assets.
What Happened and What to Watch
The market evidence supports a shared macro sequence: inflation accelerated, rate-hike expectations briefly rose, and investors sold technology and other risk-sensitive assets. Saxo Bank strategist Charu Chanana characterized the equity reaction as a repricing of capital costs, with investors reconsidering what they would pay for AI growth when borrowing costs are high and volatile.
JPMorgan analysts likewise identified financing risks and IPO timelines as central concerns for the AI trade. That helps explain why AI-linked equities came under pressure. The more defensible reading is that the CPI shock put rates at the center of a broad risk-off move in which crypto weakened too.

The bond response adds nuance. The 10-year Treasury yield fell 7.8 basis points to 5.110% as investors bought government bonds during the equity rout, a move Reuters’ account tied to demand for havens and falling growth expectations. In other words, the session was not a simple one-way repricing of every asset to higher yields.
Fed officials’ speeches, U.S. producer prices and retail sales were the next scheduled inputs identified in the market report. If further data or central-bank communication lifts the perceived chance of an October hike, pressure on AI-linked shares and higher-beta crypto could persist.
If the no-hike probability stays near the reported 75%, attention may turn to whether the technology sell-off stabilizes and whether Bitcoin can recover from around $80,764. TSMC’s third-quarter earnings are due later in the Asian trading session on Thursday. This will offer another near-term test of the AI hardware narrative, while the October 27–28 Fed meeting remains the key policy event.
