Hot inflation & war fears sink stocks
U.S. stocks slumped to close out a rare losing month, rattled by a trio of threats. Wholesale inflation in January rose more sharply than expected, while escalating conflict in Iran and anxieties over AI's economic impact further soured investor sentiment.
The January Producer Price Index (PPI) jumped 0.5%, with the 12-month figure for wholesale inflation now standing at 2.9%. The increase was driven by a 0.8% surge in the cost of services, the largest monthly rise since July 2025. While prices for final demand goods actually fell by 0.3%, the service sector's inflation was stark. A significant contributor was a 14.4% jump in margins for professional and commercial equipment wholesaling. Core PPI, which excludes food, energy, and trade services, rose 0.3% for the ninth consecutive month. Geopolitical fears exploded as the United States and Israel launched joint military strikes against Iran on February 28. U.S. officials stated the objective was to destroy Iran's missile and military capabilities and prevent the nation from obtaining nuclear weapons. Iran retaliated with missile and air strikes across the region, targeting Israel and U.S. bases in countries including Qatar, Bahrain, and the United Arab Emirates. The escalation prompted widespread international condemnation and calls for an immediate halt to the hostilities. Investor sentiment around Artificial Intelligence has also soured, shifting from momentum to anxiety. Concerns are mounting over massive capital expenditures by tech giants on AI infrastructure, with worries that the return on investment may not justify the tremendous costs. This "AI fear trade" has hammered software and megacap tech stocks, even when companies like Nvidia posted blockbuster earnings. The narrative has shifted from AI's productivity gains to its potential for widespread job displacement and economic disruption, fueling comparisons to the dot-com bubble. The combination of these pressures has pushed major U.S. stock indices to their worst monthly performance in nearly a year. February's downturn marks a significant reversal, introducing a new wave of volatility after a period of market resilience.
