Drone attacks forced Saudi Arabia to shut its East–West pipeline, the main route carrying crude to the Red Sea while traffic through the Strait of Hormuz remains restricted. The line had transported around 4 million barrels a day, about 4% of global supply, and industry sources said export stocks at Yanbu could last only five to seven days if it stays closed. Houthi forces also seized territory around the Bab el-Mandeb Strait, threatening the alternative shipping route. A prolonged outage would intensify the global fuel shock, lift inflation and complicate central-bank policy. Brent crude rose 3.2% to $107.94 early Monday, while South Korea’s Kospi fell 2.5% and the US 10-year Treasury yield reached 4.98%.
