Markets Surge After Trump Cancels Iran Strikes and Touts Peace Deal

Dramatic Market Reversal

U.S. stock markets staged a powerful comeback on June 11, 2026, after President Trump abruptly canceled planned military strikes against Iran and announced that a comprehensive peace agreement was close to finalization. The Dow Jones Industrial Average rose more than 900 points, or 1.8%. The benchmark S&P 500 moved up by more than 1.7%, while the Nasdaq Composite led gains, climbing 2.5%.

The dramatic turnaround came just one day after the Dow slid 953.33 points, or 1.87%, the S&P 500 declined 1.62%, and the Nasdaq Composite lost 1.98% amid escalating Middle East tensions and a rout in technology stocks. Oil prices tumbled more than 3% following Trump's peace announcement, providing relief to investors concerned about sustained energy price inflation.

Futures markets had already signaled optimism earlier in the day, with contracts tied to the Dow Jones Industrial Average gaining 0.68%, while S&P 500 futures rose 0.75%. The Nasdaq 100 futures added 1.16% after reports emerged that U.S. military strikes against Iran had concluded.

From War Threats to Peace Talks

The market volatility reflected the whiplash nature of Trump's public statements throughout the day. Earlier Thursday morning, the president had said that the U.S. will attack Iran "VERY HARD TONIGHT," while almost simultaneously telling Fox News the two sides are still negotiating. Trump had also threatened to seize vital Iranian oil infrastructure, including Kharg Island, "at some point in the not too distant future."

However, by afternoon, Trump completely reversed course. "Based on the fact that discussions with the Islamic Republic of Iran have been brought to the highest level of Iranian leadership and approved, I have, as President of the United States of America, cancelled the scheduled strikes and bombings against Iran this evening," he wrote on Truth Social. The president claimed that Iran had committed to forego pursuing nuclear capabilities. "They will not have a nuclear weapon, they've agreed to that — there will be no, which is the whole reason, which is a big part of the reason," Trump said.

Behind the scenes, a source with knowledge of the situation acknowledged real "breakthroughs" in US-Iran peace negotiations. The source told CNN that mediators are "cautiously optimistic" about the parties getting a deal over the finish line. Qatari negotiators reportedly played a crucial role in advancing the talks during their visit to Tehran.

Economic Stakes and Market Impact

The conflict has carried enormous economic implications, with Iran effectively shutting down the Strait of Hormuz, a narrow waterway through which about 20% of the world's energy supply travels. The ongoing Iran war is projected to slow global economic growth to its weakest pace since the Covid-19 pandemic. Global economic growth is forecast at 2.5% this year, down from 2.9% in 2025 , according to a World Bank report released on June 11.

Energy markets responded immediately to the peace prospects. U.S. crude oil futures fell 3.9% to $86.51 per barrel in extended trading. Brent futures, the international benchmark, lost 4.2% to $89.15 per barrel. The relief extended to European markets, where the pan-European Stoxx 600 index closed 0.6% higher Thursday, with major bourses in London, Paris, Frankfurt and Milan all making gains after the European Central Bank announced its first rate rise in three years.

Uncertain Path Forward

Despite Trump's optimistic proclamations, significant uncertainty remains about whether a lasting agreement will materialize. Iranian Foreign Ministry spokesman Esmaeil Baghaei appeared to downplay the prospects for a quick signing, saying Iran has not yet reached a final decision on an agreement. He added that many details had been finalized but that the "Americans keep changing their positions" , according to Iran's Tasnim news agency.

The pattern of near-agreements followed by renewed tensions has become familiar. Trump has often declared that a deal with Tehran was imminent to end the fighting only to have negotiations break off without a final agreement, leading to renewed threats and outbreaks of air strikes from the US, Iran, and Israel. Market participants remain cautiously optimistic but wary of another reversal that could reignite volatility and send energy prices soaring once again.

For now, investors are betting that diplomatic progress will prevail over military escalation, though the fragile nature of Middle East negotiations suggests that market volatility could return as quickly as it subsided.
