Wall Street Hits Record Highs as US and Iran Pause Hostilities

Donald Trump announced a pause in hostilities and upcoming peace talks in Doha, Qatar, following a weekend of retaliatory strikes in the Strait of Hormuz. This diplomatic shift, combined with a surge in artificial intelligence investments, propelled U.S. indices to record heights on June 29, 2026. The Dow Jones Industrial Average closed above 52,000 for the first time, eventually reaching a record high of 52,319.20, while the Nasdaq and S&P 500 snapped five-session declines.

Market gains were fueled by a $518 billion chipmaking hub investment by Samsung Electronics and SK Hynix, alongside Alphabet Inc.'s inclusion in the Dow. Additionally, Nasdaq announced that SpaceX would join the Nasdaq 100 on July 7. These gains contributed to the largest quarterly percentage increase for global stocks in six years, despite extreme volatility earlier in 2026 caused by conflict and oil price spikes.

Energy markets responded to the ceasefire with a gradual reopening of the Strait of Hormuz, leading to a nearly 40% quarterly drop in Brent oil prices. Meanwhile, the U.S. dollar rose for a fourth consecutive quarter, pushing the Japanese yen to a 40-year low. Financial focus has now shifted to new Federal Reserve Chair Kevin Warsh, whose hawkish signals regarding potential year-end rate hikes are being monitored at the European Central Bank's annual meeting in Sintra, Portugal.
