August CPI preview: Inflation expected to stay sticky as Fed readies rate cut

August CPI is expected to reveal persistent inflation, with headline prices projected to rise 2.9% year-over-year and core inflation holding at 3.1% annually, while monthly core prices matched July's six-month high. This sticky inflation context is critical as markets anticipate a 90% chance of a 25 basis point Fed rate cut next week, with growing speculation for a larger cut following recent weaker jobs data. Despite limited direct tariff impact on consumer costs so far, August's declining PPI suggests businesses may be absorbing tariff costs or facing softening demand, indicating ongoing challenges for the Fed's disinflationary efforts.

Analysis

The market is anticipating August's Consumer Price Index data will confirm persistent inflation, with headline prices forecast to accelerate to 2.9% year-over-year and core inflation remaining sticky at 3.1%. The expected 0.3% month-over-month rise in core prices, matching July's six-month high, underscores the challenge for the Federal Reserve's disinflationary efforts, particularly with what Wells Fargo economists describe as sticky services inflation. This inflationary context contrasts sharply with market expectations, which currently price a 90% probability of a 25 basis point rate cut at the next policy meeting, per the CME FedWatch tool. Pressure for monetary easing is amplified by signs of economic softening, including a significant downward revision of 911,000 jobs and a surprise 0.1% monthly decline in producer prices. This PPI contraction suggests businesses may be absorbing tariff costs or facing weakening domestic demand, complicating the Fed's decision-making as it weighs sticky consumer prices against a deteriorating labor market outlook.

Key Decisions for Investors

• Given the divergence between persistent inflation metrics and the market's 90% pricing of a Fed rate cut, investors should prepare for heightened volatility in fixed income and equity markets surrounding the CPI release and subsequent FOMC meeting.
• Monitor the Federal Reserve's forward guidance closely, as a rate cut in the face of sticky 3.1% core inflation would signal a greater policy focus on the weakening labor market over immediate inflation targets.
• Consider the risk to corporate earnings implied by the contracting Producer Price Index, which suggests businesses are either absorbing cost pressures, thus compressing margins, or facing softening domestic demand.
