U.S. equities are ending the quarter on weak footing, with the S&P 500 on track to fall roughly 7% in the first quarter of 2026 - the largest quarterly drop since 2022. The pullback reflects a mix of investor concern about inflation, renewed geopolitical risk linked to the Iran war, and questions about how artificial intelligence will reshape software firms and the wider corporate landscape.
Market participants point to several key dynamics behind the sell-off. A notable factor has been a jump in oil prices, which has fed inflation fears and altered expectations for monetary policy. At the same time, the megacap technology group that led the post-COVID bull market has experienced a pronounced correction, amplifying downward momentum across risk assets.
Fixed income has not offered the typical shelter. Yields on U.S. Treasury notes have risen in recent weeks after a previously quiet stretch earlier in the quarter. The yield on the U.S. 10-year note fell 10.4 basis points to 4.336% on Monday after last week approaching 4.50% for the first time in 2026, and exchange-traded funds that track long-term U.S. Treasury debt are down roughly 1% so far this year. Those moves have helped push investors who began the year anticipating interest-rate cuts into a more uncertain stance about the Federal Reserve's near-term trajectory.
"The setup this year has been one where there’ve been increasing questions around what the rate cycle could be," said Matt Orton, chief market strategist at Raymond James. "Inflation has been a headwind, more so than it has been over the past few years, in terms of wondering what the read-through would be from increased energy prices both in the U.S. and the global economy."
Technology stocks have been a central pressure point. Investor nerves over how AI might disrupt incumbents, combined with heavy investment in AI infrastructure, have contributed to sharp declines among the so-called Magnificent Seven. Nvidia, Apple, Alphabet, Meta, Microsoft, Amazon and Tesla are all down for the quarter, and the retreats in Microsoft and Tesla are on track to top 20%.
"We had the AI-disruption narrative start and impact the Mag-7 stocks and have that spread to financial and cybersecurity stocks," said Chris Galipeau, senior market strategist from the Franklin Templeton Institute. "Software stocks were the epicenter of that. It started the unwind in big tech, which is where the pressure point is."
Beyond equities, strains in credit markets have also seeped into investor sentiment. Concerns in the private-credit space have been heightened after reports that some large funds were limiting withdrawals, a development some observers likened in tenor - though not in scale - to early stress seen in prior credit episodes. Those constraints have added to cross-market anxiety about potential losses and valuation risk.
"Prior to the war, the two issues in the market were really the AI disruption and private credit," said James Ragan, co-chief investment officer and director of investment management research at D.A. Davidson. "Venture capital industries have the most exposure and banks have exposure we don’t understand yet. And the feeling is there’s going to be some losses in those credit markets."
Political policy has also been cited as a source of volatility. Tariff measures implemented under the Trump administration against major trading partners were highlighted by one market strategist as an additional factor destabilizing investor confidence.
"We’re in the process of putting in a major top and in the early innings of this. You shouldn’t be thinking about where to buy. You should be playing defense to protect profits," said Bill Strazzullo, chief market strategist at Bell Curve Trading in Boston.
For market watchers, the convergence of rising energy costs, a reassessment of rate cut odds, AI-related sector rotation and credit-market unease has created a challenging backdrop for risk assets heading into the second quarter. Investors who began 2026 positioned for easier monetary policy now face a more complex matrix of inflation and geopolitical risks that could shape returns in the months ahead.
