Oil topped $100 per barrel Monday amid escalating hostilities in the Middle East and widening stress on oil shipping operations and the global energy infrastructure. The yen weakened against the dollar, moving closer to a key threshold of 160 per dollar, a level where authorities intervened to support Japan’s currency in 2024. Stocks also tumbled, with the Nikkei 225 shedding around 6.9% early Monday, while long-term bond yields rose.
