Stock market futures climbed on June 28 as reports emerged that the U.S. and Iran had agreed to halt military strikes and would resume peace talks this week, offering markets a reprieve from weeks of geopolitical tension that had roiled trading.
S&P 500 futures gained 0.8%, while Nasdaq 100 contracts advanced 1.1%, according to Bloomberg, as bargain hunters pushed stocks higher after a weak week that sent the U.S. benchmark to its second-worst performance of the quarter. AI-related stocks led premarket gains.
The momentum reflected relief over the renewed commitment to diplomacy. A senior U.S. official told Axios that “we decided to stop all the kinetic activity,” using military terminology for strikes and attacks. Both sides agreed to stand down “for now” and allow vessels to move freely through contested waters as technical talks continued.
The ceasefire has been fragile since it began just 11 days earlier. Both the U.S. and Iran had resumed strikes in recent days over competing interpretations of their memorandum of understanding, particularly regarding control of the Strait of Hormuz—a critical waterway for global energy shipments. The new halt came before planned talks scheduled for Tuesday in Qatar’s capital to work out the dispute.
The Path Forward on Sanctions and Nuclear Issues
The broader framework underpinning the talks reflects significant concessions by both sides. The United States waived sanctions on Iran for 60 days following the first round of high-level negotiations that concluded on June 22 in Switzerland, according to Reuters and Al Jazeera. Iran, in turn, agreed to allow UN nuclear inspectors to return to the country as part of the agreement.
Mediators said the U.S. and Iran approved a roadmap aimed at reaching a final deal within 60 days, with negotiators establishing working groups on oversight, sanctions, and nuclear matters. Vice President JD Vance, who headed the U.S. delegation in Switzerland, said the talks created a “good foundation for a successful final deal,” according to The Guardian.
The stakes for markets remain high. Oil prices have swung sharply on each twist in the negotiations—falling when peace prospects brightened and rising when tensions flared. A sustainable resolution could ease energy costs and reduce the risk premium that has weighed on equities. The fragility of the ceasefire and the complexity of the nuclear and Strait of Hormuz issues mean volatility is likely to persist as talks continue.
