Markets Rally Broadly as Oil Prices Tumble 5%; Nvidia GTC 2026 and Fed Week in Focus

• S&P 500 gained 1.01%, NASDAQ 100 rose 1.13%, and Dow Jones added 0.83% on the session.
• Brent crude pulled back sharply, declining approximately 5% but remaining near the $100/bbl level.
• Stocks opened higher at the start of Fed week, with investors positioning for the upcoming interest rate decision.
• Morningstar noted the U.S. stock market has remained resilient amid the war in Iran, though risks persist.

U.S. equities posted strong gains on Monday, March 16, 2026, with the S&P 500 climbing 1.01%, the NASDAQ 100 advancing 1.13%, and the Dow Jones Industrial Average rising 0.83%. The rally was fueled by a sharp 5% decline in oil prices, easing fears that the ongoing Iran conflict would sustain crude above the psychologically critical $100-per-barrel level. Declining energy costs provided a tailwind for both stocks and bonds, as investors recalibrated inflation expectations heading into a pivotal Federal Reserve policy week.

Despite the surface-level calm, analysts noted significant turbulence beneath the headline indices. One veteran analyst warned that current market dynamics mirror patterns seen in 2008, while Barron's reported that Wall Street is beginning to doubt whether the S&P 500 can reach the 8,000 level this year. The Motley Fool flagged a rare market alarm not seen in 25 years, adding a cautionary undertone to the day's optimism.
