Asian Markets Soar to New Records, Led by AI Boom Amid Iran Talks Progress

Tokyo's Nikkei 225 hit an all-time record of 72,831.73 on Monday, surging 1.6%, as optimism over U.S.-Iran peace talks sent oil prices sliding and Asian markets mixed. High-level negotiations wrapped up early Monday in Switzerland, with mediators Pakistan and Qatar announcing a roadmap toward a final deal to end the 114-day conflict, according to AP News.
Brent crude fell 1.4% to $79.42 per barrel as traders priced in the possibility of reopening the Strait of Hormuz. U.S. futures, however, dipped — a sign that markets remain cautious about whether the fragile diplomatic progress will hold.
Japan's Nikkei 225 closed at 72,364.82 on Monday — up 1.6% — after touching the intraday record of 72,831.73. Technology stocks led the rally, driven by the global AI infrastructure boom. SoftBank Group rose 2.4%, surpassing Toyota as Japan's most valuable listed company. Seoul's Kospi gained 0.4% to 9,084.37, crossing the 9,000-point threshold for the first time in history.
Chip stocks powered Seoul's gains. SK Hynix surged 4.7% in a single session. Analyst Peter Kim of KB Securities called the current environment a "once-in-a-generation surge" in semiconductor earnings, noting South Korea is now home to multiple $1 trillion tech companies, according to The Guardian. Still, Neil Newman of Astris Advisory Japan warned the Nikkei is "getting a little stretched."
High-level talks at the Burgenstock resort in Switzerland began Sunday with U.S. Vice President JD Vance and Iranian Foreign Minister Abbas Araghchi leading their delegations. The talks got off to a rocky start. Iranian delegates briefly walked out after President Trump posted on Truth Social warning Iran "won't have a country" if the Strait of Hormuz stays closed, according to The Guardian.
Despite the tense opening, mediators Pakistan and Qatar issued a joint statement at 3:07 AM Monday declaring the high-level phase complete. The statement set a strict 60-day deadline — ending in August 2026 — to reach a full nuclear and regional security deal. Araghchi called it "major progress" on X, saying Pakistani and Qatari mediation had "delivered a path to end the Lebanon war."
Brent crude has already fallen sharply from wartime highs above $100 per barrel. It now sits near $79.42 — a drop tied directly to hopes that the Strait of Hormuz, the world's most critical oil shipping lane, could reopen. If a final deal holds, analysts expect crude to stabilize near $70 per barrel, relieving pressure on global inflation.
Technical teams remain at Burgenstock for the rest of the week to work out details on lifting the U.S. naval blockade and releasing frozen Iranian assets, according to AFP. One complication: an explosion at Qatar's Ras Laffan natural gas facility on Sunday injured 54 people. Mediators quickly clarified it was likely an industrial accident, not an attack, which calmed energy markets.
Peace talk optimism is only part of the story. Japan and South Korea together produce 72% of the world's semiconductors and 95% of advanced AI accelerator chips, according to StoneX. Global tech giants are projected to spend $697 billion on AI infrastructure in 2026, per Bloomberg. That spending flood has sent both countries' stock markets surging well past levels explained by their domestic economies alone.
The Bank of Korea may soon face a difficult choice. The equity rally has been so strong that it is punishing government bonds — pushing yields higher. Analysts say the central bank may need to raise interest rates to cool a market that has run far, far ahead of the broader economy, according to The Guardian.
