Wall Street Whiplash: Markets Soar on CPI, Crash on PPI Inflation Shock

Stock markets initially rallied to record highs on Tuesday after July’s consumer inflation data came in slightly better than expected at 2.7% annually, matching June’s level.

However, the celebration was short-lived as Thursday’s Producer Price Index shocked investors with a 0.9% monthly surge – the biggest jump since June 2022 and far above the 0.2% forecast.

The dramatic wholesale inflation spike caused stocks to reverse course, with major indexes falling as traders scaled back expectations for multiple Fed rate cuts. The PPI surge suggests tariff-related costs are finally hitting the production pipeline, potentially foreshadowing higher consumer prices ahead and complicating the Fed’s September rate decision.
