Overview
Shipping activity in two strategic Middle Eastern waterways declined over the weekend, with data showing a sharp drop in transits through the Bab el-Mandeb Strait and subdued crossings in the Strait of Hormuz. The falloff in traffic follows reported Houthi attacks on Saudi-linked targets and a pause in U.S. airstrikes against Iran that has extended into a second day.
Bab el-Mandeb: marked slowdown
According to shipping movements compiled by Kpler, just eleven commodity vessels passed through the Bab el-Mandeb Strait on Sunday - the smallest daily count recorded in several months. Tanker movements in the narrow channel that links the Red Sea with the Gulf of Aden have eased since reported strikes by Iran-backed Houthi forces in Yemen targeted Saudi ships last week.
Those strikes prompted worries that the conflict involving Iran could widen and begin to affect additional parts of the Middle East, with potential consequences for the already critical flows of oil and other goods that transit the region.
Reported Houthi strikes on Saudi facilities
A military spokesperson for the Houthis said the group attacked sites owned by the Saudi state oil company Aramco in the cities of Jizan and Yanbu on Saturday. Video released after the incidents showed smoke near the Jizan refinery. The Jizan facility can process up to 400,000 barrels per day.
In Yanbu, two missiles were reported to have been intercepted by a U.S.-made Patriot system that was operated by Greek forces during the engagement. Yanbu has emerged as an important export route for Saudi oil because it permits shipments that avoid the Strait of Hormuz.
Saudi-backed Yemeni forces responded to the Houthi operations by striking Houthi launch sites and weapons depots in the Marib and al-Jawf areas.
Strait of Hormuz: limited weekend traffic
Meanwhile, the Strait of Hormuz - the key waterway off Iran’s southern coast that has been central to Tehran’s recent confrontations with the U.S. and Israel - saw fewer than ten commodity vessels cross daily over the weekend. On Sunday, seven ships were recorded passing through, including three oil products tankers described as Iranian-linked. Additionally, three vessels transited with their transponders switched off.
The muted activity in both waterways came even as a fragile cessation in fighting between the U.S. and Iran held into its second day. That pause has supported cautious hopes that diplomatic engagement could lead to an extended ceasefire.
Pause in U.S. airstrikes and naval posture
Sources cited in reporting said Iran would halt its attacks provided the U.S. sustains its current pause in airstrikes. The pause followed 13 consecutive rounds of U.S. strikes on Iranian targets, with the Pentagon stopping the operation late on Friday. No U.S. air attacks have been reported since that halt.
The U.S. military stated that its naval blockade of Iran remained fully operational but did not offer an explanation for the suspension of airstrikes. A senior Trump administration official said diplomacy remained the president’s preferred route, while also asserting that Iran had been shown the consequences of refusing serious negotiations. Iran refrained from attacking neighboring countries on Saturday.
Separately, reporting attributed to a major U.S. newspaper indicated that President Donald Trump chose to pause attacks on Iran in part to prevent depletion of American stockpiles of antimissile interceptors and air defense munitions in the region.
Implications
The confluence of Houthi operations in the Bab el-Mandeb area and constrained movements through the Strait of Hormuz highlights the vulnerability of multiple oil and commercial shipping corridors to regional hostilities. Observed reductions in vessel transits reflect an immediate operational response by shippers and raise the prospect of broader disruptions should attacks continue or expand.
