Despite rising geopolitical tensions in the Middle East, with U.S. Secretary of State Marco Rubio reporting Iran’s mining of the Strait of Hormuz, Asia-Pacific markets opened largely positive. Japan’s Nikkei 225 surged to a record high, extending early gains by 2.94%, while other regional indices showed mixed performance.
The resilience of Asian markets comes as investors appear to look past the U.S.-Iran conflict, with oil futures also showing gains. U.S. markets also saw modest rises in the previous session, with the S&P 500 closing above 7,600 for the first time.

Asia-Pacific equity markets experienced a largely positive open on Wednesday, with Japan's benchmark Nikkei 225 index soaring to a historic record high. This robust performance unfolded as investors seemingly brushed aside escalating tensions surrounding U.S.-Iran negotiations aimed at resolving the conflict in the Middle East.
Geopolitical concerns intensified following remarks from U.S. Secretary of State Marco Rubio on Tuesday. Rubio alleged that Iran has deployed mines across "large segments" of the vital Strait of Hormuz. Addressing the Senate Foreign Relations Committee, he stated, "They're firing on commercial ships and they've mined large segments of Hormuz — international waters." This marked his first congressional appearance since the onset of the Iran war on February 28.
A White House official, speaking to CNBC, confirmed that the Pentagon had successfully neutralized numerous mines and over 40 minelaying vessels. The Strait of Hormuz is an exceptionally critical maritime passage, particularly for global energy markets, having previously facilitated approximately 20% of the world's oil supplies before the recent conflict.

Australia's S&P/ASX 200 managed a gain of 0.82%, even though the country's GDP growth for the first quarter of the year came in at 2.5% year-on-year, slightly below economists' forecasts of 2.6%. This growth was tempered by softer household spending, reduced government consumption, and disruptions to the mining sector caused by severe weather.
Elsewhere in Asia, India's Nifty 50 declined by 0.78%, with the BSE Sensex also slipping 0.85%. South Korean markets remained closed for a public holiday.
