People pass a board showing the current levels of the Tokyo Stock Exchange along a street in Tokyo on June 12, 2026. Japan's Nikkei share index soared more than four percent on June 12 after US President Donald Trump withdrew his threat of further strikes against Iran and said a deal to end the war could be signed in coming days.
AFP Oil prices tumbled, and stocks soared on Monday after the United States and Iran said they had reached a deal to end their war that will reopen the Strait of Hormuz, sending a wave of relief through global markets. The two sides confirmed an announcement from mediator Pakistan, with a signing ceremony set to take place in Switzerland on June 19, bringing an end to three months of conflict that has sent energy prices soaring and revived fears of another inflation spike.
The Strait — a vital maritime chokepoint through which roughly 20 per cent of the world’s crude oil supply transits — was effectively closed by Tehran soon after US-Israel strikes on Iran launched the conflict. “The Deal with the Islamic Republic of Iran is now complete,” US President Donald Trump wrote on social media Sunday as he marked his 80th birthday.
“I hereby fully authorise the toll-free opening of the Strait of Hormuz,” he added. “Ships of the World, start your engines. Let the oil flow!” Iran’s Deputy Foreign Minister Kazem Gharibabadi then said the deal put an “immediate end” to the war, with talks on a “final agreement” due within two months.
The content of the agreement, which follows weeks of fraught negotiations and periodic threats from Trump of fresh hostilities, remained unclear. Crude prices tanked as much as five per cent on Monday, with West Texas Intermediate approaching 83.30. Both main contracts have come down since their initial surge past $`110 soon after the conflict started.
The sharp drop in oil costs soothed growing concerns that soaring inflation could force central banks to begin hiking interest rates again. Data last week showing a jump in US May consumer prices — coupled with strong job creation — had ramped up bets on the Federal Reserve tightening before the end of the year.

Lower yields give duration and growth equities room to breathe,” said Stephen Innes at SPI Asset Management. “The dollar loses a bit of its wartime bid… in one headline chain, the market moves from bunker pricing to reopening pricing,” he added. Traders will now have their eye on the next steps, he added, including the official signing in Switzerland, mine clearance and Israeli restraint.
Michael Wan at MUFG sounded a note of caution. “While it is certainly good news for the global economy and Asia that a deal has been announced, whether this sticks and remains viable depends, among other things, on the details of the negotiated terms,” Wan wrote.
Asian equities surged, led by Tokyo and Seoul, which both closed around five per cent higher thanks to another flood into tech firms, fuelled by last week’s record-breaking `$75 billion IPO by Elon Musk’s SpaceX. Shanghai, Sydney, Singapore and Taipei rose more than one per cent while Hong Kong advanced 0.7 per cent, and London, Paris and Frankfurt all had upbeat starts.
