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

U.S. consumer inflation is projected to have accelerated in August, with CPI rising 0.3% month-over-month to 2.9% annually and core CPI also increasing 0.3% monthly to 3.1% annually. This uptick is attributed to higher gasoline costs and the increasing pass-through of tariffs on various goods as businesses deplete pre-tariff inventories. Despite these inflationary pressures, the expected increase is not seen as strong enough to derail the Federal Reserve's anticipated interest rate cut next week, though an undershoot could signal weak demand and prompt further easing.

Analysis

U.S. consumer inflation is expected to have accelerated in August, presenting a complex backdrop for the upcoming Federal Reserve policy meeting. Consensus forecasts from a Reuters survey indicate a 0.3% month-over-month rise in the Consumer Price Index (CPI), elevating the annual rate to 2.9%, which would be the largest year-on-year gain in seven months. Core CPI, which excludes food and energy, is also projected to climb by 0.3%, maintaining its 3.1% annual pace. The primary drivers of this anticipated inflation are higher gasoline prices and, critically, the increasing pass-through of tariffs on imported goods as businesses exhaust their pre-tariff inventories, which are reportedly equivalent to just 1.3 months of sales. Despite these firming price pressures and rising concerns of potential stagflation, the market has fully priced in a quarter-percentage-point interest rate cut from the Fed. The upcoming CPI data is therefore a crucial test; an undershoot on inflation could be interpreted as a sign of weak consumer demand limiting corporate pricing power, thereby reinforcing the case for a more sustained easing cycle from the Fed.

Key Decisions for Investors

• Monitor the forthcoming CPI data as a key catalyst; an upside surprise could challenge the market's conviction in a dovish Fed, while a significant miss would reinforce expectations for a series of rate cuts.
• Investors should assess exposure to consumer-facing sectors, such as retail and apparel, which are particularly sensitive to the dual pressures of passing on tariff-related costs and navigating potentially weak consumer demand.
• Given the explicit mention of stagflation concerns, it is prudent to review portfolio positioning for resilience in an environment of rising inflation coupled with potentially slowing economic growth.
• Distinguish between the short-term market reaction to the CPI print and the Fed decision, and the longer-term inflationary impact from tariffs, which economists suggest may not fully materialize for several more months.
