Broad US price increases expected in August amid tariff pass-through

U.S. consumer inflation is projected to have accelerated in August, with the CPI estimated to rise 0.3% after a 0.2% July increase, primarily due to higher gasoline and food costs, alongside an increasing pass-through of tariffs on goods as businesses deplete pre-tariff inventories. Core CPI and PCE are also forecast to show acceleration, potentially reaching 3.1% year-over-year. Despite this broader inflationary pressure, which could fuel stagflation concerns, analysts widely expect the Federal Reserve to proceed with a fully priced-in 25-basis-point rate cut next week, as the current pace is not anticipated to derail monetary easing. Upcoming data will be critical in assessing the full impact of tariffs and whether consumer demand can absorb further price increases.

Analysis

Upcoming U.S. Consumer Price Index (CPI) data for August is expected to show an acceleration in inflation, driven by a confluence of rising energy costs, higher food prices, and the increasing pass-through of trade tariffs. Economists surveyed forecast a 0.3% month-over-month increase, lifting the annual rate to 2.9%, the largest gain in seven months. More critically, core CPI, which excludes volatile food and energy, is also projected to rise 0.3% MoM, holding at a 3.1% annual rate. This pressure is attributed to businesses beginning to sell goods that incurred tariffs, as pre-tariff inventories, equivalent to just 1.3 months of sales, are now depleted. Despite these inflationary signals and concerns of potential stagflation following recent weak labor market data, the Federal Reserve is widely anticipated to proceed with a 25-basis-point interest rate cut. The key uncertainty for markets is whether consumer demand is robust enough to absorb these higher costs; a CPI figure below expectations could signal weakening demand and justify further Fed easing, whereas a stronger-than-expected print would complicate the central bank's policy outlook.

Key Decisions for Investors

• Given that a 25-basis-point rate cut is fully priced in, investors should focus more on the Federal Reserve's forward guidance following the CPI release, as it will reveal their tolerance for inflation overshooting the target in the face of potential economic weakness.
• Monitor margin guidance from consumer discretionary and retail sectors, as their ability to pass on tariff-related costs without damaging sales volume will be a key indicator of underlying consumer health and corporate pricing power.
• Consider positioning for increased market volatility around the data release and subsequent FOMC meeting, as a significant deviation from inflation expectations could challenge the current market narrative of a dovish Fed.
• Re-evaluate exposure to inflation-sensitive assets and fixed-income duration, as persistent upside surprises in inflation, even if tolerated by the Fed initially, could eventually pressure bond yields higher and stoke stagflation fears.
