Yanbu, the Saudi Red Sea port that handled 92% of The Kingdom's seaborne crude exports in June, is now shipping about 3.75 million barrels a day of crude and condensate, Vortexa estimates, with 62% bound for India, Japan, China and South Korea1. Yanbu sits on the western coast, north of the Bab el-Mandeb chokepoint the 23 July embargo closed to Saudi loadings, which is why the reroute has funnelled so much flow through it.
A single terminal carrying that share of a major exporter's crude concentrates the risk. It puts an entire seaborne supply chain behind one port and one corridor, so any further disruption to the Red Sea approach hits nine-tenths of the flow at once rather than a slice of it.
For desks pricing Brent-Dubai relative demand, the split between Atlantic and Middle Eastern grades, the destination mix matters more than the raw volume. The barrels are clearing east into Asian refiners while the Atlantic basin sees almost none of them. The reroute therefore tightens Suez tonnage without loosening European crude supply, so the tension shows up in freight and in the East-West arbitrage rather than in the Brent flat price.
