Asian markets displayed mixed performance Tuesday as geopolitical tensions with Iran continued to influence trading sentiment. According to The Hindu BusinessLine, Japan's Nikkei 225 climbed 1.1% to 59,485.54 driven by strong gains in tech-related companies, with Tokyo Electron rising 4.4% and tech and energy giant SoftBank Group Corp. gaining 5.5%. South Korea's Kospi jumped 1.8% to 6,327.73 and Taiwan's Taiex advanced 1.7%, while the Hang Seng in Hong Kong edged 0.1% lower to 26,382.30 and Shanghai Composite lost 0.3% to 4,068.28. Australia's S&P/ASX 200 declined 0.1% to 8,942.80, reflecting the varied regional response to ongoing Iran-US developments.
The optimism surrounding Iran-US negotiations has been significantly dampened by recent developments that have thrown talks into doubt. As reported by The Hindu BusinessLine, US President Donald Trump attacked critics after a second round of talks with Iran was thrown into doubt by the US Navy's seizure of an Iranian-flagged cargo ship. Trump said Vice President JD Vance would be going to Islamabad, but the Iranian side made no commitment to more talks, creating uncertainty about the next round of negotiations. The next big deadline is looming on Tuesday night at 8 p.m. Eastern time, which is early Wednesday Tehran time, when a ceasefire agreement between the United States and Iran is scheduled to expire. Mizuho Bank noted that "the current dynamic is one of a precarious balance of truce," with the all-consuming question being whether both sides can seize on the talks to land on a US-Iran deal that ends the war.
Oil prices experienced a decline as markets processed mixed signals regarding the Strait of Hormuz reopening and ongoing geopolitical tensions. According to The Hindu BusinessLine, Brent crude slipped just 0.4% to $95.10 per barrel, while US benchmark crude oil lost 0.9% to $86.66 per barrel. The price for a barrel of Brent crude remained above USD95, reflecting continued market uncertainty about the situation. Worries over disruptions of supplies of oil from the Persian Gulf if Iran continues to block tankers from exiting the Strait of Hormuz are clouding investor sentiment. Oil prices climbed Monday following the latest rise of tensions between the United States and Iran, but the moves were more modest than they were earlier in the war, with prices remaining well below the USD119 per barrel level for Brent crude when fears were at their highest.
MSCI Inc. will extend the review period for Indonesia's stock market status to June as it assesses the impact of recent regulatory reforms. According to Bloomberg, the index compiler is reviewing the scope, consistency and effectiveness of new data sources and measures related to investability and shares available for public trading. As a result of the one-month extension, previously announced measures such as freezing index additions will continue. MSCI will remove securities flagged under Indonesia's new high shareholding concentration framework and use new disclosure data to adjust free-float estimates. The measures include doubling minimum float levels to 15%, with a phase-in period of up to three years for some companies. The Indonesia Stock Exchange has also named nine firms with more than 95% of shares held by a small group of investors to boost ownership-transparency standards, including tycoon-linked companies PT Barito Renewables Energy and PT Dian Swastatika Sentosa, sending their stocks down.
Despite geopolitical tensions, US markets demonstrated resilience with major indices maintaining their record-breaking levels. According to The Hindu BusinessLine, on Monday, the S&P 500 slipped 0.2% from its all-time high and the Dow industrials edged less than 0.1% lower, while the Nasdaq composite fell 0.3%. US stocks, meanwhile, gave back a bit of their record-breaking rally following the modest retreat. US companies have been reporting big profits for the first three months of 2026, helping to support the market. About a tenth of companies in the S&P 500 have already reported their results for the start of 2026, with nearly nine out of 10 delivering a bigger profit than analysts expected, according to FactSet. If the rest of the companies in the index match analysts' expectations, overall earnings per share for S&P 500 companies will end up 13% higher than a year earlier, with major earnings reports scheduled this week including UnitedHealth Group on Tuesday, Tesla on Wednesday and Procter & Gamble on Friday.
