The Fed doesn't think inflation will run amok again. The PCE price gauge will help clue us in.

The upcoming Personal-Consumption Expenditures (PCE) price index is forecast to show a 0.3% rise in August, with the Federal Reserve's preferred core measure, which excludes volatile food and energy, advancing a more modest 0.2%. This data is crucial for investors assessing the Fed's outlook that inflation will peak around 3% due to tariffs before subsiding, rather than escalating, with the core PCE providing a key indicator of future inflationary trends.

Analysis

The upcoming release of the August Personal-Consumption Expenditures (PCE) price index is a critical data point for assessing the Federal Reserve's inflation outlook. Market consensus forecasts a 0.3% month-over-month increase in the headline PCE, but attention is centered on the core PCE, which is projected to rise by a more modest 0.2%. The Fed gives greater weight to the core measure, as its exclusion of volatile food and energy costs provides a clearer signal of underlying price trends. These forecasts align with the central bank's current narrative that inflationary pressures, partly driven by tariffs, will likely peak around 3% before subsiding. While the expected figures are not inherently alarming, investors will be scrutinizing the report's granular details for any signs of broader or more persistent inflation that could challenge the Fed's relatively benign view and alter its policy trajectory.

Key Decisions for Investors

• Investors should closely monitor the core PCE reading, as a material deviation from the 0.2% forecast would be the primary catalyst for market repricing of future Federal Reserve rate actions.
• A higher-than-expected inflation figure could challenge the dominant 'transitory peak' narrative, potentially triggering increased volatility and a defensive rotation away from rate-sensitive assets.
• If the data comes in-line with or below expectations, it would reinforce the current stable outlook, likely supporting risk assets by affirming the view that the Fed can maintain its current policy path without needing to become more aggressive.
