Bitcoin Stuck Below $86K as PCE Inflation Print Raises Methodology Concerns

Bitcoin hovered above $83,000 on Thursday, giving back earlier gains after a lower-than-expected US inflation reading was complicated by significant methodology changes. BTC/USD traded near $83,550 at the start of Q4 — historically Bitcoin's strongest quarter — after posting impressive third-quarter gains of 42.7%, its best Q3 performance since 2017, according to data from CoinGlass. The latest rally stalled on Wednesday when Bitcoin reversed at $85,600.

The Personal Consumption Expenditures (PCE) price index, the Federal Reserve's preferred inflation gauge, came in at 3.4% year-on-year for August, below the 3.7% expectation. Core PCE rose 3.0% annually, per the Bureau of Economic Analysis. However, the release incorporated methodology revisions affecting portfolio management, investment advice, computer software, and legal services. Market commentary outlet The Kobeissi Letter estimated these changes alone could reduce core PCE inflation by up to 20 basis points, noting that July headline and core figures were also revised downward by 30 basis points. Markets appeared to discount the reading as a result.

Despite the price stagnation, Bitcoin derivatives data signaled cautious optimism. BTC-denominated open interest fell nearly 20% while price rose 35% from its August low, suggesting leverage was cleared before the latest move higher. A new $60 million cluster of estimated liquidation exposure appeared near $83,000 on CoinGlass's liquidation heatmap, close to key support at $82,500 — a level analysts identified as critical for Bitcoin's broader rebound from June lows.

Risk assets broadly struggled in the wake of the PCE release. The S&P 500 closed Wednesday down 0.25% at 7,651 points, while the Dow Jones Industrial Average shed 0.86%. Data from the CME FedWatch Tool showed markets still pricing in meaningful odds of a quarter-point rate increase at the next Federal Reserve meeting, leaving crypto traders on watch for the next directional catalyst.
