The S&P 500 closed out the first quarter of 2026 with a decline of 9.2 percent, the worst quarterly performance since the COVID-19 market crash of early 2020, as a convergence of geopolitical shocks, rising tariffs, and persistent inflation eroded investor confidence across virtually every sector.
The benchmark index shed roughly 485 points over the three-month period, with the bulk of the damage concentrated in February and March as the Iran Strait of Hormuz crisis pushed energy costs higher and a new round of US-China tariff escalations spooked technology investors.
"We are in a macro environment that punishes complexity," said Sarah Kwan, chief strategist at Meridian Capital. "When you pile geopolitical risk on top of tariff uncertainty on top of still-elevated rates, the market's default is to reprice for the worst case."
Technology stocks bore the steepest losses, with the Nasdaq Composite falling 12.4 percent in Q1. The Philadelphia Semiconductor Index was the hardest-hit sector gauge, tumbling nearly 18 percent on supply chain disruptions tied to export controls on advanced chips shipped to China.
Energy was the sole major sector to post gains, rising 14.7 percent as oil prices climbed above $110 per barrel. Defensive sectors, utilities, consumer staples, and healthcare, outperformed the broader market but still finished in negative territory for the quarter.
The Federal Reserve held rates steady at its March meeting, citing conflicting signals between a still-tight labor market and slowing consumer spending. Fed Chair Jerome Powell acknowledged the tariff situation added meaningful uncertainty to the inflation outlook, tempering expectations for rate cuts in the second half of 2026.
Recession probability models at Goldman Sachs have risen to 38 percent for the next twelve months, up from 22 percent at the start of the year.
