The Nikkei 225 Index jumped 2.87% to close at 65,158, while the broader Topix Index added 1.29% to 3,943 on Monday, with Japanese equities climbing to fresh record highs as oil prices declined amid signs that the US and Iran were moving closer to a deal to reopen the Strait of Hormuz. A full reopening of the key shipping route would provide relief for major Asian economies heavily dependent on Middle Eastern oil imports, while softer crude prices also help ease inflationary pressures and concerns over additional interest rate hikes. Technology and artificial intelligence-related shares further lifted the market, with SoftBank Group now up roughly 40% in three sessions following reports that two of its portfolio companies, OpenAI and SB Energy, are advancing toward US initial public offerings. Other notable tech gainers included Kioxia Holdings (+14%), Fujikura (+14.4%), Ibiden Co (+8.7%), Advantest (+3.4%) and Lasertec (+12.8%).
