The producer-price index jumped 1.3% in September, blowing past the anticipated 0.6% increase and marking the sharpest monthly climb in over four years. This surge in wholesale costs initially sparked volatility, yet the broader market found stability as investors retreated into safe-haven assets. The 10-year Treasury yield settled at 5.086%, while the 30-year bond yield slipped to 5.427%—each recording their largest single-day declines in more than a year.

Gold futures mirrored this flight to safety, climbing $62.90 to reach $4,147.70 per troy ounce. While the S&P 500 managed a 0.33% gain to close at 7,744.11, the tech-heavy Nasdaq Composite struggled to maintain momentum, ending with a marginal 0.08% rise at 26,713.03. The Dow outperformed, finishing the session at 52,178.28 as the market recalibrated expectations following the unexpected inflation data.
