Asian stock markets traded mixed on Tuesday after the U.S. military confirmed it carried out what it described as “self-defense” strikes in southern Iran, adding fresh uncertainty to already fragile peace negotiations and keeping investors focused on developments in the Middle East.
The strikes reportedly targeted missile launch sites and boats believed to be involved in laying naval mines, raising concerns that tensions in the region could escalate again despite ongoing diplomatic discussions aimed at ending the conflict.
The attacks came shortly after U.S. President Donald Trump said negotiations with Iran were “proceeding nicely,” creating a confusing picture for global investors trying to assess whether the region is moving closer to peace or toward further instability.
Despite the military action, U.S. stock futures moved sharply higher in early trading, signaling optimism that negotiations could still produce a breakthrough agreement. Oil prices, however, remained volatile as traders weighed the risk of prolonged disruptions in the Strait of Hormuz against hopes for a diplomatic resolution.
The U.S. military said Monday’s operations were carried out to protect American troops from threats posed by Iranian forces. Officials added that restraint was exercised because of the current ceasefire arrangement with Iran. Tehran did not immediately issue an official response, and few details were released regarding the nature of the alleged threats or how the strikes might affect ongoing negotiations.
Financial markets have remained highly sensitive to every development linked to the conflict, with investor sentiment swinging rapidly between optimism and caution based on comments from Washington, Tehran and regional mediators.
Stephen Innes of SPI Asset Management said markets currently appear to be pricing in a successful diplomatic outcome even though major disagreements between the United States and Iran remain unresolved.
According to Innes, Washington has continued projecting confidence about the talks, while Iranian officials have maintained that no final agreement has yet been reached. The gap between those positions has left investors uncertain about whether peace efforts will ultimately succeed.
In Japan, the Nikkei 225 index slipped 0.4% to 64,897.64 after recently reaching a record closing high. Analysts said investors likely locked in profits while monitoring geopolitical developments and fluctuations in oil prices.
Hong Kong’s Hang Seng index rose 0.3% to 25,668.55, supported by gains in technology and consumer shares, while mainland China’s Shanghai Composite index fell 0.7% to 4,122.87 amid concerns over global trade and energy costs.
South Korea’s Kospi jumped 2.9% to 8,075.71 as traders returned from a public holiday and reacted positively to improving sentiment surrounding global technology stocks and artificial intelligence-related companies.
Australia’s S&P/ASX 200 declined 0.4% to 8,653.80 as energy and mining shares experienced mixed trading following the sharp swings in crude oil markets.
Meanwhile, futures for major U.S. indexes pointed higher ahead of Wall Street’s reopening after the Memorial Day holiday. Futures linked to both the S&P 500 and the Dow Jones Industrial Average gained around 0.6%, reflecting hopes that diplomatic progress could eventually stabilize markets.
Oil prices remained one of the biggest drivers of global market sentiment. Benchmark U.S. crude oil dropped more than 4% to $91.59 a barrel after sharp volatility over recent sessions. Brent crude, the international benchmark, climbed $1.57 to $94.99 per barrel after suffering a major decline the previous day.
Analysts said traders remain focused on the future of the Strait of Hormuz, the critical shipping route that handles a large share of the world’s oil exports. The ongoing conflict has disrupted tanker traffic through the passage, preventing shipments from reaching customers across Asia and other parts of the world.
The reopening of the strait is now viewed as one of the most important factors likely to determine the future direction of global oil prices. Countries heavily dependent on Middle Eastern oil supplies, including Japan, have been particularly vulnerable to the disruptions.
European markets also moved higher earlier in the day as investors responded to signs of possible diplomatic progress. France’s CAC 40 gained 1.1%, Germany’s DAX advanced 1.0%, and Britain’s FTSE 100 added 0.2%.
Regional officials indicated over the weekend that the United States and Iran were nearing an agreement that could end the conflict, reopen the Strait of Hormuz and involve Tehran surrendering its stockpile of highly enriched uranium as part of a broader settlement.
Currency markets were relatively stable during Tuesday’s trading session. The U.S. dollar edged slightly higher against the Japanese yen, trading at 158.94 yen compared with 158.91 yen previously. The euro weakened modestly to $1.1634 from $1.1645.
Investors are expected to remain cautious in the coming days as financial markets continue reacting to military developments, diplomatic negotiations and oil price fluctuations. Any indication of progress toward reopening the Strait of Hormuz could ease concerns over energy supply disruptions, while renewed conflict risks could quickly reignite volatility across global markets.
