AI summary

What happened, with direct paths to the underlying reporting

August PCE inflation cooled more than anticipated, with headline rising 0.3% and 3.4% YoY, while core rose 0.2% and 3.0% YoY. Despite remaining above the 2% target, softer readings could dim rate-hike bets and support risk assets, including the S&P 500, as investors adjust earnings and multiple expectations to a slower policy path.

PCE index rose 0.3% m/m, 3.4% YoY in August; below 0.4%/3.7% expected.
Core PCE rose 0.2% m/m, 3.0% YoY; below 0.3%/3.3% expectations.
Fed monitors PCE headline but uses core as inflation gauge; still above 2% target.
Smaller inflation gains may delay aggressive tightening, supporting risk assets and S&P 500.
