How to read Hormuz, Petroline, and Bab el-Mandeb: three doors, not one oil map
Maps flatten oil into one arrow out of the Gulf. Physical trade uses doors. The Strait of Hormuz is the front door for most Gulf exports. Saudi Arabia’s East-West pipeline, often called Petroline, is a land bridge from eastern fields to the Red Sea port of Yanbu. Bab el-Mandeb is the southern gate of the Red Sea: Asia-bound cargoes that left Yanbu still have to pass it. When a headline says “supply risk,” ask which door moved.
Hormuz: the door the numbers still name
In normal years Hormuz carries on the order of twenty million barrels a day of oil and products, most of it headed to Asia. U.S. Energy Information Administration figures cited in Anadolu Agency reporting put crude and other petroleum liquids through Hormuz at an average 21.6 million barrels a day in the fourth quarter of 2025, then 4.9 million barrels a day in the second quarter of 2026 — roughly a 77 percent drop after the war that began at the end of February. IEA commentary in the same reporting cycle put available Gulf bypass pipeline export capacity in a 3.5 to 5.5 million barrels a day range, far short of replacing the strait.
Petroline and Yanbu: a bypass sized for a pause
Petroline moves crude from Abqaiq-area processing toward Yanbu. Pipe capacity is commonly cited near 7 million barrels a day, but part of that feed serves Red Sea refineries and power, and marine loading at Yanbu under stress has been described in the 3.5 to 5 million barrels a day neighborhood rather than as a full Hormuz substitute. Argus reported the line running hard when Hormuz was effectively closed earlier in the war. In September 2026 Saudi authorities shut the line as a precaution after attacks on sections in the Riyadh and Madinah regions; Anadolu and tanker-tracker notes then described Yanbu loadings that could not be assumed durable without restored pumping. A bypass that is offline returns the kingdom’s export problem to Gulf terminals and whatever Hormuz transit remains possible.
Bab el-Mandeb: the second gate for Asia
Crude that reaches Yanbu can move toward Europe via Suez or Egypt’s SUMED line. Cargoes aimed at Asia still exit through Bab el-Mandeb. EIA figures in the same Anadolu account showed Bab el-Mandeb oil flows rising from 5.4 million barrels a day in the fourth quarter of 2025 to 8.1 million barrels a day in the second quarter of 2026 as some Saudi barrels rerouted west then south. Houthi-linked risks and sparse daily transit counts reported by tracking firms are therefore not a separate “Red Sea story.” They are the second door on the same bypass.
Escorts are not throughput
A convoy or war-risk cover can move a ship. It does not restore pre-war daily volume. When freight and insurance stay elevated while a minister says routes are open, believe the invoice. This desk’s notes on jammed doors and escorted barrels start from loadings, not from the press conference.
What this means for Korea
Korea imports almost all of its crude and buys a large share from the Middle East. Landed cost is a function of which door is open, what freight and war-risk premia clear that door, and the won. A softer Brent print with Hormuz still thin and Petroline still impaired is not the same bill as a soft print with both doors working.
Reading the three doors together
Hormuz down and Petroline full is a bypass working at its limit. Hormuz constrained and Petroline shut is a delivery crisis dressed as a production debate. Yanbu open but Bab el-Mandeb unsafe is an Asia problem even when Europe has a Suez path. OPEC+ quota slides matter after barrels can load. Until then, the doors write the constraint. This is research.
