Saudi oil exports ‘go dark’ amid Houthi threat

Saudi Arabia's crude oil exports via the Red Sea are becoming increasingly opaque as tankers switch off their tracking signals to evade attacks by Yemen's Houthi rebels. Analysts report that recent loadings from Yanbu have been conducted "dark," meaning their movements are not publicly visible.

This surge in "dark voyages" is creating significant challenges for market watchers, including international agencies and traders, who rely on ship-tracking data to forecast global oil trends. Widely differing export estimates from various ship-tracking firms are emerging, clouding the true scale of any disruption.

The Houthis declared a maritime embargo targeting Saudi Arabia on July 20, vowing to attack vessels linked to the U.S. and its allies involved in the conflict with Iran. They have since claimed responsibility for attacks on Saudi-linked tankers and oil facilities, prompting vessels to take evasive measures by disabling their tracking systems.

The situation highlights the escalating Houthi threat to vital shipping lanes and the complexities of monitoring energy markets amidst geopolitical tensions. The lack of transparent data makes it difficult to ascertain the precise impact on Saudi crude flows and the broader global supply.
