Markets News, June 15, 2026: Stocks Surge, Oil Prices Tumble on U.S.-Iran Deal; SpaceX Stock Soars in Day 2 of Trading

U.S. stock markets rallied on June 15, 2026, following the announcement of a U.S.-Iran agreement to end their months-long war and reopen the Strait of Hormuz, a critical oil shipping route. The tech-heavy Nasdaq Composite led gains with a 3.1% increase, while the S&P 500 rose 1.7% and the Dow Jones Industrial Average climbed 1.2% to a record close. Oil futures tumbled as traders anticipated resumed traffic through the strait, with West Texas Intermediate dropping 4% to $81.50 per barrel and Brent crude falling to $83.75, though lingering uncertainties about the deal’s implementation persisted. SpaceX stock continued its strong debut, surging 20% on its second day of trading after closing nearly 20% above its IPO price the prior day. The stock’s rally contributed to broader tech gains, with the PHLX Semiconductor Index jumping over 5% and all seven Magnificent Seven stocks closing in positive territory, led by Meta’s nearly 5% gain. Meanwhile, the yield on the 10-year Treasury slightly dipped to 4.48%, reflecting cautious optimism amid inflation concerns and geopolitical tensions. The Federal Reserve’s upcoming policy meeting, led by new Chair Kevin Warsh, drew attention as investors awaited signals on potential rate adjustments. While a rate hike was unlikely, Warsh’s press conference on Wednesday was expected to provide clues about future monetary policy, especially after May’s inflation spike to a three-year high. Cryptocurrencies also advanced, with Bitcoin reaching $66,500, while the U.S. dollar index dipped marginally to 99.70. Quantum computing stocks, including D-Wave, saw gains as analysts predicted further sector growth. The market’s response highlighted broader investor confidence in tech and risk assets following the U.S.-Iran deal, though economic and geopolitical risks remained key focal points for traders.
