Saudi Arabia has loaded no crude for export through Bab el-Mandeb, the strait between Yemen and the Horn of Africa that links the Red Sea to The Gulf of Aden, since the Houthis declared an embargo on 23 July. The diverted volume has poured north into the Suez Canal, where crude traffic climbed 106% in a single week to 1.06 million barrels a day, on Kpler cargo tracking reported by AFP and carried on the AP and Reuters wires12.
The Houthis are the armed movement that controls north-west Yemen and the eastern shore of the strait. Bab el-Mandeb is the southern gate for any Gulf cargo heading west toward Suez and the Mediterranean, so shutting it to Saudi loadings does not remove the barrels from the market; it reroutes them. Every cargo that once cleared the strait quickly now takes the long way round, and the arbitrage against Asian buyers resets with it.
To a spreads desk the position sits not in the flat price but in the physical shift. The reroute concentrates tonnage demand on the Yanbu-Suez leg, pulls crude north through a single contested corridor, and leaves the direction of Brent to swing on diplomatic headlines while the routing cost accrues on every barrel. Where that cost sits, and why the freight screens most desks read cannot see it, is the trade this week.
