August 2026 U.S. CPI Seen Extending Disinflation Streak to a Third Month

The U.S. Bureau of Labor Statistics is set to publish the August 2026 Consumer Price Index on Sept. 11 at 8:30 a.m. ET. Wall Street expects another step down in inflation, a pattern the Federal Reserve has been looking for as it weighs its next policy move. FactSet consensus calls for headline CPI to rise 3.3% year over year, easing from 3.4% in July and extending the decline from the 4.2% peak recorded in May. Core CPI, which excludes food and energy, is projected at 2.4% YoY and 0.2% month over month. If realized, the core rate would cool from July's 2.5% and move closer to the Fed's 2% goal. Monthly momentum looks less comforting. Economists see a 0.4% increase for August versus 0.1% in July, with gasoline prices the main driver after providing relief the prior month. July's report was dominated by shelter costs, which accounted for roughly two-thirds of the overall increase, while lower energy prices helped keep the monthly figure subdued. August is shaping up as a partial reversal: energy rebounding even as the broader disinflation trend persists. The recent path underscores that trend. Headline CPI peaked at 4.2% in May, fell to 3.5% in June, eased to 3.4% in July, and is now expected at 3.3%. Timing may matter as much as the print. The release arrives five days before the Fed's Sept. 16 policy meeting. A 3.3% headline reading would support a hold in rates and could encourage officials to signal a more dovish tilt into year-end. Core CPI at 2.4% would be especially consequential given its proximity to target. A result at or below consensus would likely weaken the argument for further tightening, while an upside surprise could revive uncertainty heading into the meeting. Crypto and other risk assets have become increasingly sensitive to macro data over the past year, and CPI is a key catalyst. A cooler-than-expected report would likely bolster risk-on positioning in digital assets by easing inflation expectations, potentially pressuring the dollar and lowering the opportunity cost of holding non-yielding assets such as Bitcoin. The forecast 0.4% monthly gain adds complexity: a hotter-than-expected monthly number could rattle risk markets even if the year-over-year trend remains constructive. Shifts in Fed expectations also matter for stablecoin yields and DeFi lending rates. If markets price in a less restrictive stance, spreads that have made on-chain fixed income attractive versus traditional money markets could narrow. Investors will also be watching shelter closely. Housing-related costs have been among the stickiest components for more than two years, and their outsized impact in July points to uneven progress. On Sept. 11, the focus won't be limited to whether headline CPI matches the 3.3% forecast; the composition of inflation—the mix of shelter, energy and services—will shape whether policymakers feel confident acting on Sept. 16.
