Asian share markets dithered on Monday as the threat of imminent tariffs lurked in the background, while bitcoin surged on news it would be included in a new U.S. strategic reserve of cryptocurrencies. U.S. President Donald Trump on social media announced five digital assets he expected to include in a new reserve, including bitcoin, ether, XRP, solana and cardano. MSCI's broadest index of Asia-Pacific shares outside Japan was flat, though Japan's Nikkei rose 1.1%, helped by a softer yen.
