The Houthi threat to shipments of Saudi crude oil from the Red Sea hasn’t abated and more tankers laden with Saudi oil appeared to have made the transit through the Bab el-Mandeb chokepoint in dark mode. Two tankers that had loaded Saudi crude at the Red Sea port of Yanbu have likely exited the Bab el-Mandeb Strait in southern direction with their transponders off, Bloomberg reported on Monday, citing vessel-tracking data it is monitoring. The Greece-owned Lesvos tanker of the Suezmax size and the supertanker Desh Vaibhav, flying the Indian flag, were last transmitting near the Yanbu port on Saturday, before re-appearing on the AIS monitoring systems offshore southern Oman on Monday, according to the data. Last week, six tankers turned away in the Arabian Sea from Bab el-Mandeb after the Houthi threats to Saudi shipping and actual attacks on tankers prompted Saudi Arabia to re-route its crude oil exports, again, to Egypt. Separately, more than half a dozen empty supertankers were en route to Egypt's Sidi Kerir port last week to pick up Saudi crude, as the world's top crude oil exporter is re-routing – again – its export tactics to avoid the new threat at Bab el-Mandeb.
