The Nikkei 225 Index climbed 0.55% to close at 53,413 on Monday, building on gains from the previous session as investors turned cautiously optimistic on prospects for a Middle East ceasefire. The US, Iran, and a group of regional mediators are reportedly negotiating terms for a potential 45-day truce that could pave the way for a more lasting resolution to the conflict. This development followed President Donald Trump setting a new deadline for Iran and intensifying threats against its power plants and other civilian infrastructure if the Strait of Hormuz is not reopened. Japan remains highly exposed to oil supply disruptions due to its heavy reliance on Middle East imports, prompting authorities to tap emergency reserves and seek alternative energy sources. Notable market gainers included Kioxia Holdings (4.4%), Furukawa Electric (4.2%), Lasertec (4.5%), Advantest (1.7%), and Disco Corp (2%).
