Asia-Pacific markets experienced an uptick on Wednesday, with Japan’s Nikkei 225 achieving a record high, as investors seemed to overlook the uncertainties surrounding U.S.-Iran negotiations intended to resolve the Middle East conflict. Tensions have escalated between Washington and Tehran, with Secretary of State Marco Rubio stating on Tuesday that Iran has mined “large segments” of the Strait of Hormuz. “They’re firing on commercial ships and they’ve mined large segments of Hormuz — international waters,” Rubio stated during his address to the Senate Foreign Relations Committee. This represents his initial appearance before Congress following the Iran war on February 28.

A White House official informed that the Pentagon has eliminated a significant number of mines and more than 40 minelaying vessels. The Strait of Hormuz serves as a vital conduit for global energy markets, with approximately 20% of the world’s oil supplies transiting through this waterway prior to the onset of conflict. Japan’s Nikkei 225 concluded Wednesday’s trading session with a gain of 2.50%, closing at 68,402.13, while the Topix experienced an increase of 1.83%, finishing at 3,996.20. Mainland China’s CSI 300 increased by 0.49% to 4,938.81, whereas Hong Kong’s Hang Seng experienced a decline of 1.62% during its final hour of trading.

Australia’s benchmark index increased by 0.70%, reaching a level of 8,785.70. The country reported GDP growth of 2.5% year on year for the first three months this year, falling short of economists’ expectations of 2.6%. Growth faced challenges due to diminished household spending, reduced government consumption, and the adverse effects of severe weather disruptions on the mining sector. India’s Nifty 50 declined by 0.83%, and the BSE Sensex experienced a decrease of 0.90% as of 3:40 am. South Korea’s markets were closed in observance of a holiday.

The West Texas Intermediate futures for June exhibited an increase of 2.05%, reaching a price of $95.68 per barrel as of 3:39 am. Brent crude futures for July increased by 1.89%, reaching a price of $97.81 per barrel. S&P 500 futures and Nasdaq 100 futures were trading near the flatline, as were futures associated with the Dow Jones Industrial Average. During Tuesday’s regular session, the broad-based S&P 500 rose 0.13% to end above 7,600 for the first time ever, while the Dow added 228.91 points, or 0.45%. The Nasdaq Composite recorded a modest increase of 0.03%.
