On 20 July, Houthi forces declared a full maritime blockade against Saudi Arabia, closing the Bab al-Mandab Strait to vessels servicing Saudi ports. Following this move, Tanker Xin Long Yang, a Chinese VLCC carrying Saudi crude, turned back towards Suez rather than cross the Yemeni border, and two more Tankers followed suit. Within days, the Houthis said they had gone further, striking two Saudi-flagged Tankers.with missiles and drones and causing fires
The Bab al-Mandeb Strait carries around 7% of global oil output. The Strait of Hormuz has been under severe strain since the US-Israel war on Iran began in late February, and our own transit data below shows it accelerating towards a halt rather than recovering, down around 95% since the ceasefire collapsed in early July.
A sustained Bab al-Mandeb shutdown would compound that; the two chokepoints could remove a significant volume of the world’s oil and gas supply. While the two straits are separate, they have become increasingly linked, with Saudi Arabia routing up to 7mbd of crude oil via the Red Sea to work around the Hormuz disruption.
Taking a look at VesselsValue trade data, transit volumes for the Strait of Hormuz have continued falling across the last three weeks amid the back-and-forth policies. Tanker and LNG volumes transiting the strait were down around 62% from the Monday the ceasefire broke down to the following Monday. They then fell a further 87% into this Monday, leaving transit volume down around 95% versus the pre-breakdown baseline overall, enough to suggest a real pause in movement rather than simply week-week variation.
The sharpest day-to-day swings seen in the days immediately after the ceasefire broke down have eased since, though volumes are still suppressed relative to the pre-breakdown baseline. Transit dates are marked by first known position past the tripwire, a fixed line drawn using VesselsValue Trade search across the strait that flags a transit once a vessel reappears on the far side, consistent with the tripwire search logic. Since vessels typically go dark crossing the strait, it is worth flagging that this likely lags actual transits somewhat, so current-week figures may still tick up as more positions resolve.
TC rates moved only modestly week on week, continuing the gentle drift seen since the announcement and reversal rather than reacting freshly to it, consistent with a market that had already priced in Gulf risk. TC rates have risen week-on-week for most sectors with VLCCs up from 110,139 USD/day to 113,310 USD/day, an increase of c. 3%. Suezmaxes were also up c.3%, while Afras dipped slightly. Product Tankers were flatter and LR1 and MR1 each nudged up roughly 1%. VLCC’s current week average is now running about 48% above the one year average of 76,485 USD/day.
Oil prices have moved on the Red Sea news: Following 13 consecutive nights of US and Iranian strikes in the Middle East conflict, oil prices broke 100 USD/bbl on Thursday for the first time since May. The key signals to watch: whether the Houthis follow through with further attacks beyond Encelia and Layla, if any more Tankers reroute away from Bab al-Mandeb entirely, and whether transit volumes and TC rates in the Hormuz data above start reflecting this second chokepoint risk on top of the existing Iran-related disruption.
