Tanker Traffic Through Bab el-Mandeb Falls to Multi-Month Low as Ceasefire Leaves Saudi Oil Routes Exposed
Only 11 tankers transited the strait on 2026-07-26, even as a US-Iran pause in strikes pulled ICE Brent crude front-month below $88.
Tanker traffic through the Bab el-Mandeb Strait fell to a multi-month low on Sunday (2026-07-26), with only 11 vessels carrying commodities through the waterway, as Houthi attacks on Saudi oil infrastructure along the Red Sea coast choked a corridor that handles roughly 7% of the world's energy trade, according to OilPrice.com.5,3
ICE Brent crude front-month was trading at $87.35 a barrel early Tuesday (2026-07-28), a partial recovery from a more than 8% collapse on Monday (2026-07-27) that pushed prices below $88 — itself a sharp reversal from the $102 peak reached during the week of 2026-07-20, when US-Iran hostilities were at their most intense, according to NBC News. The prior week's gains of more than 9% have been largely unwound in two sessions.6
The United States and Iran paused strikes over the weekend after 13 consecutive nights of attacks that broke an earlier truce, NBC News reported. Both sides have described the halt as creating space for diplomacy. Neither has announced a durable settlement.6
Saudi Arabia's exposure is the reason the strait count matters. Saudi crude shipments through the Red Sea port of Yanbu averaged above 4 million barrels per day since June — up from 973,000 bpd during the same period in 2025 — and surged further to 4.7 million bpd after the ceasefire with Iran collapsed on 2026-07-13, OilPrice.com reported. Around 70% of Saudi energy exports now move through Yanbu and the Red Sea, leaving the kingdom directly in range of Houthi interdiction in a way it was not during the 2023-2024 Red Sea disruptions.3
Iran has instructed the Houthi movement to stand ready to close the strait if Washington follows through on threats to strike Iranian power infrastructure, OilPrice.com reported. A source close to the Houthis confirmed the group has positioned stockpiles of drones and advanced missiles across Yemen's highlands overlooking Hodeidah and the Gulf of Aden.3
By Wednesday (2026-07-22), a MarineTraffic analyst described the Bab el-Mandeb risk picture as "deteriorating." The 11-tanker transit count on Sunday (2026-07-26) confirms that assessment has not aged badly. Houthi rebels also announced their intention to impose a maritime blockade on Saudi Arabia, NBC News reported — a declared objective that goes well beyond the opportunistic shipping strikes of the previous two years.4
The Strait of Hormuz sits behind all of this as the deeper systemic pressure. Prior to the current conflict, approximately 20% of the world's oil passed through Hormuz, with its repeated closure sending energy prices higher and global markets lower throughout the fighting, NBC News reported. The strait also handles approximately 10% of global seaborne trade, including nearly 8% of global LNG flows. A simultaneous disruption at both Hormuz and Bab el-Mandeb leaves no clean rerouting option.6,1
Markets sold oil on the ceasefire news. But the supply picture has not normalized. Saudi Arabia cannot quickly redirect 4.7 million bpd away from Yanbu. Rerouting around the Cape of Good Hope adds weeks of transit time and substantial freight cost — a burden that falls on Asian buyers of Saudi crude and on cargoes tracked by JKM, which stood at $21.43 per MMBtu early Tuesday (2026-07-28).3,5
On Tuesday (2026-07-14), US Central Command restarted its blockade of all Iranian shipping and ports after the ceasefire and memorandum of understanding between Washington and Tehran collapsed, Foreign Policy reported. That action preceded the current diplomatic pause, which means the legal and operational architecture of the blockade remains in place even as both sides hold fire.2
The more than 8% single-session drop in ICE Brent crude front-month on Monday (2026-07-27) prices in genuine relief that strikes have paused. It may also be pricing in a resolution that does not yet exist on paper. Eleven tankers through Bab el-Mandeb on a single day is a number that belongs to a crisis. Yanbu shipment volumes in the coming days will show whether the diplomatic pause has any physical consequence — or whether drone stockpiles across Yemen's highlands remain the operative fact on the ground before any framework takes hold.5,3,6
