Markets Rise on Iran Deal Hopes Amid US Strikes

U.S. stock futures climbed Tuesday morning after President Trump described negotiations with Iran as proceeding nicely, even as American forces carried out fresh strikes on targets in southern Iran. Dow futures rose more than 300 points at one point, with S&P 500 and Nasdaq futures also posting solid gains ahead of the first trading session after the Memorial Day holiday.

The moves came amid conflicting signals from the Middle East. Trump had warned that Washington stood ready to shift to an offensive posture if talks collapsed, while U.S. Central Command confirmed strikes on missile launch sites and Iranian boats suspected of mine-laying operations in the Strait of Hormuz. Officials framed the actions as defensive measures taken during an active ceasefire, yet the exchange underscored how quickly the situation can escalate.

Oil markets reflected the uncertainty. Brent crude pushed back above $96 a barrel after earlier weakness, while West Texas Intermediate futures fell sharply at times. Prices have remained elevated for months due to disruptions in Middle East energy flows, keeping costs higher for American drivers and manufacturers. European shares gave up some ground as investors digested the news, with the STOXX 600 slipping modestly.

Asian markets showed stronger enthusiasm. South Korea's benchmark index surged past 8,000 for the first time, closing at a record 8,047.51 after gaining more than 2.5 percent. Investors there appeared to price in the possibility that any deal could ease shipping restrictions through the Strait of Hormuz, a critical route for global energy supplies.

Analysts noted that last week's U.S. stock gains had already built in assumptions of de-escalation. The S&P 500 posted its longest weekly winning streak since late 2023, while the Dow rose more than 2 percent. Those advances occurred as traders weighed the chance that diplomacy might finally reduce the risk premium baked into energy prices.

Still, questions remain about how durable any agreement might prove. Past efforts at regional diplomacy have often unraveled under competing pressures, and the latest strikes suggest that military activity has not fully paused even as talks continue. Secretary of State Marco Rubio indicated a final deal could still require several days of negotiations.

For American households, the stakes center on energy costs and broader economic stability. Elevated oil prices have already complicated inflation trends and raised doubts about near-term Federal Reserve moves. Traders now see a slightly higher chance of a July rate hike than they did a month ago, reflecting the persistent volatility tied to Middle East developments.

The contrast between optimistic futures trading and actual battlefield updates highlights how markets often front-run headlines that may or may not deliver lasting relief. With both diplomatic language and military action unfolding in quick succession, investors appear to be betting that the former will eventually outweigh the latter.
