- S&P 500 rose 0.62% to 6,824.66, while the Nasdaq Composite and Dow Jones Industrial Average also posted gains, turning the Dow positive for the year (+0.25%).
- West Texas Intermediate crude futures surged over 3% to $97.87 per barrel after briefly breaching $100.
- Meta Platforms shares jumped 2.6% after the company debuted a new artificial‑intelligence model.
- Trump announced a pause on attacks against Iran and warned that U.S. forces would stay deployed until Tehran fully complies with the ceasefire terms.
- Benjamin Netanyahu said Israel would open direct talks with Lebanon, while Iran’s parliamentary speaker Mohammad Bagher Ghalibaf condemned Israel’s attacks as a ceasefire violation.
- Strait of Hormuz traffic remained limited after the ceasefire, with only bulk carriers passing despite Iran’s pledge to reopen the waterway for two weeks.
Why it matters: Investors gained as the major indexes rose, buoyed by hopes the ceasefire will restore shipping through the Hormuz Strait, while oil producers saw higher prices. The continued U.S. military presence and limited strait traffic signal lingering supply‑chain risk, tempering the rally.
