Bitcoin briefly climbed above $85,000 on Sept. 30 before slipping back below $84,000 following the release of August personal consumption expenditures inflation figures. The U.S. Bureau of Economic Analysis reported headline PCE inflation at 0.3% month over month and 3.4% year over year, with core PCE — excluding food and energy — up 0.2% month over month and 3.0% year over year. The data arrived alongside an annual update to national economic accounts that revised earlier estimates, requiring careful comparison across time periods. While headline inflation remained above the Federal Reserve's 2% target, the figures added context to monetary policy discussions without dictating the central bank's next move. At 3:28 p.m. UTC, Bitcoin traded near $84,000, marking a modest 0.56% gain over the prior 24 hours but failing to sustain the earlier rally. The move coincided with a rebound in U.S. Treasury yields, which rose to about 5.276% for the 10-year note, and a corresponding uptick in the UK 30-year government bond yield near 5.939%. Stocks and crude oil prices also recovered during the session, with the SPDR S&P 500 ETF Trust trading around $766.82 and Brent spot crude climbing toward $102.20 per barrel. Gold, tracked via a contract for difference, settled near $4,163.92 an ounce, below its earlier peak above $4,200. The U.S. Dollar Index hovered near 101.39 after retreating from earlier highs. Analysts noted that the August PCE report reflects price changes from that month, while subsequent manufacturing and employment data cover September, leaving the broader inflation and growth narrative still evolving. For Bitcoin, the session ended with a failed test of the $85,000 level and a retreat to below $84,000, leaving traders to assess whether momentum could extend beyond the initial buying surge.
