Stock market futures surged on June 15, 2026, after U.S. and Iranian officials announced a breakthrough peace deal framework aimed at ending their months-long conflict and reopening the Strait of Hormuz, a vital shipping corridor that had been blockaded for nearly four months.
S&P 500 futures climbed 1.19 to 1.24%, while Nasdaq 100 futures popped 2%, and Dow futures added 0.85%, according to CNBC. The rally extended globally, with Asian markets posting significant gains after the news broke.
President Donald Trump announced the completion of the deal late Sunday on Truth Social, stating that he had authorized the toll-free reopening of the Strait of Hormuz and the immediate removal of the U.S. naval blockade of Iranian ports. Pakistan’s Prime Minister Shehbaz Sharif, who mediated the talks, confirmed that an official signing ceremony would take place Friday in Switzerland.
The deal framework calls for the immediate cessation of military operations on all fronts and includes the suspension of sanctions on Iranian oil sales, according to reporting from Iranian news agency Mehr. The agreement is described as a memorandum of understanding rather than a final peace treaty, according to a Wikipedia featured snippet.
Oil markets responded with sharp declines as investors priced in the end of supply disruptions. Brent crude, the international benchmark, fell about 4.5% to below $83.40 per barrel, while U.S. crude dropped 4.8% to $80.80, according to CNBC. The blockade of the Strait of Hormuz had caused a daily shortfall of about 14 million barrels of oil, according to the International Energy Agency, driving energy prices to elevated levels worldwide.
Asian stock markets surged on the news. Japan’s Nikkei 225 soared 5.5% in morning trading, while South Korea’s Kospi jumped as much as 5.7%, according to Al Jazeera. Taiwan’s Taiex climbed 2.7%, and Australia’s ASX200 rose about 1.5%. The moves reflected investor relief at reduced geopolitical risk and the prospect of normalized global energy flows.
The geopolitical risk premium—the extra cost traders demand for oil due to conflict uncertainty—has been a major factor in energy prices since the U.S.-Iran conflict began in February 2026. A reduction in tensions may lower that premium significantly, according to analysis from ANZ’s head of Asia research Khoon Goh, who told Al Jazeera that the fall in oil prices would provide relief for central banks worried about inflation.
Despite the deal announcement, industry experts cautioned that a full return to normal shipping could take many months. The Strait of Hormuz blockade has trapped thousands of vessels in and around the waterway, and potential Iranian naval mines may require clearing before traffic can fully resume, according to statements from shipping industry leaders cited by Al Jazeera.
