The Nikkei 225 Index jumped 2.1% to above 50,000 while the broader Topix Index climbed 1.6% to 3,322 on Monday, with both benchmarks hitting new all-time highs amid optimism that the US and China were nearing a trade deal ahead of the Trump-Xi meeting in South Korea on Thursday. Trade officials from both countries said they had reached consensus on key issues including export controls, fentanyl, and shipping levies after productive weekend talks in Malaysia. Investors also positioned for a likely Federal Reserve rate cut this week following softer US inflation data, while the Bank of Japan is expected to maintain its current policy stance. Gains were widespread, led by strong advances in major stocks such as SoftBank Group (2.6%), Advantest (5%), Mitsubishi Heavy (2.6%), Kawasaki Heavy (8%), and IHI Corp (2.9%).
