Will annual inflation be 3.4% in August?

Analysis

The market question centers on the Consumer Price Index, which is due from the Bureau of Labor Statistics on September 11. Recent data show headline PCE inflation at 3.7 percent and core PCE near 3.3 percent, underscoring that price pressures remain elevated rather than cooling. Forecasters treat 3.4 percent as the working reference point for August CPI, but the case for an exact repeat looks weaker than it might seem. Energy prices, especially gasoline, are expected to rebound after recent declines. Food costs are accelerating too. Forecasters are pointing to a monthly headline gain of 0.3 to 0.4 percent. A move of that size typically shifts the annual rate rather than leaving it parked exactly where it was previously. Core inflation remains sticky, and Fed officials describe price pressures as elevated rather than improving. Several policymakers have flagged the August report as pivotal for the September meeting. That language usually accompanies expectations of a firmer print, not a flat one. The outcomes cluster tightly around 3.4 percent. A reading of 3.3 percent carries real weight on the downside. A reading of 3.5 percent is still plausible on the upside if gasoline rebounds sharply. That spread of live possibilities makes a precise landing on 3.4 percent the less likely single outcome, even though it remains the median guess. The single thing to watch: the gasoline component within the August data. A sharp rebound there would lift the annual rate clear of 3.4 percent, while a milder move could still tip it down to 3.3.
