Bitcoin Just Broke $85,000 on Ice-Cold Inflation Data — but CryptoQuant Warns the Rally Is 'Running Out of Steam'

Bitcoin did what it does best on Wednesday: it waited for the inflation print, sniffed weakness, and ripped. But the celebration lasted about an hour — and one closely watched gauge says the party might already be over.

Ice-cold inflation, hot crypto

The U.S. Bureau of Economic Analysis delivered a genuine surprise on Wednesday morning. The personal consumption expenditures price index — the inflation gauge the Federal Reserve watches more closely than any other — rose just 3.4% over the year through August, down from 3.7% in July and well below the 3.7% consensus forecast.

Core PCE — the Fed's preferred gauge — rose 3.0% year-on-year against a 3.3% forecast, and just 0.2% month-on-month against 0.3% expected. Headline PCE rose 0.3% on the month, in line with estimates.

Bitcoin reacted the way you'd expect. The cryptocurrency surged from below $84,000 to roughly $85,600 within an hour of the release at 12:30 UTC, with altcoins riding the wave — ZEC up 3.6%, SOL up 2.2%, ETH up 1.5%. Gold jumped about $20 in a straight line, snapping a week-long downtrend. Shorter-dated Treasury yields fell and stock futures rose as traders cut their bets on an October rate hike — a hike that markets had been pricing at a 72.5% chance.

Why this print actually mattered

Crypto had been having a rough week. Treasury yields at multiyear highs had strengthened the dollar, making gold and crypto less attractive, and bitcoin had struggled to hold momentum around $84,000 after several subdued sessions. The market was braced for bad news — and got the opposite.

A cooler-than-expected inflation reading tempers expectations for further Fed rate hikes, and cheaper future money is rocket fuel for risk assets. New York Fed President John Williams helped the mood on Tuesday, saying the central bank could wait until December before raising rates again. The next Fed meeting lands October 27–28, with the next PCE release due October 29.

One caveat the fine print: this release included the annual update to the national economic accounts, revising data back to January 2021 — so the gap between the number and expectations isn't a perfectly clean read on August alone. And consumer spending stayed firm, with nominal spending up 0.9% and inflation-adjusted spending up 0.6%, leaving the Fed weighing softer inflation against resilient household demand.

The warning hiding inside the rally

Here's where it gets uncomfortable. CryptoQuant, the on-chain data platform traders live by, says the heralded bull-market return is already in trouble: "The rally is running out of steam," its analysts wrote, flagging short-term profit-taking — while its bull score gauge sits near a perfect 90, historically a flashing sign that a local top is near.

The price action agreed: bitcoin couldn't hold $85,000 and slipped back toward $83,700–$84,500 within hours of the spike. ETF flows are sending the same mixed signal. Last week clocked the biggest crypto ETF inflows all year at over $3.2 billion, but this week started with an estimated $56 million of net sales on Monday, per J.P. Morgan.

So which is it — a breakout or a bull trap? The honest answer is that one soft inflation print doesn't set the trend; it just buys time. If the October 29 PCE confirms the cooling and the Fed stands pat on October 27–28, bitcoin has room to run. If the data firms back up, that "perfect score" warning will look prescient.
