Saudi Rerouting Turns Voyage Time Into VLCC Pricing Power

Two tankers carrying Saudi crude turned north in the Red Sea after the Houthi warning, while a third vessel heading empty toward Yanbu also reversed. None had received a direct threat.^{[1, 2]} That distinction matters: the first constraint on Saudi exports is emerging through commercial avoidance, not physical damage.^{[1, 2, 3]} Crude-tanker transits through Bab el-Mandeb fell from 16 on Monday to five on Tuesday, then recovered to nine on Wednesday.^[3]

The existence of another route does not settle Saudi Aramco’s exposure. The relevant measure is how much crude can be loaded at Yanbu and delivered to Asia once displaced Hormuz volumes are already pressing against the Red Sea system and southbound passage carries a new risk premium.^{[4, 5]}

Yanbu’s success as a Hormuz bypass has pushed the Red Sea system toward its practical edge

Yanbu has moved from secondary outlet to core export infrastructure. Before the Hormuz crisis, it shipped an average 763,229 barrels a day of crude and condensate; since the crisis began, the average has risen to 3.75 million barrels a day.^[4] Kpler put June exports at about 4.1 million barrels a day, equivalent to roughly 64 percent of the Saudi crude that would otherwise have left through Hormuz.^[6] Saudi Arabia can move as much as 7 million barrels a day through the East-West pipeline, but about 2 million barrels are used by western Saudi refineries, while market estimates place Yanbu’s effective loading capacity nearer 4 million barrels a day.^{[7, 8]} The bypass is already working close to its practical edge.^[8]

The Houthi policy attacks that workaround at its most exposed point. Formal notices described vessels using Saudi ports as potential targets, making commercial activity at those ports more important than flag or ownership.^[9] That gives shipowners, charterers and insurers reason to reprice any voyage linked to Yanbu even without an attack.^{[2, 3, 9]} Twelve Yanbu-loaded vessels remained inside the Red Sea, two others switched off their tracking transponders near Bab el-Mandeb, and incoming empty tankers also showed hesitation.^[6]

This matters because Asia has absorbed most of Yanbu’s expansion. Since March, 62 percent of Yanbu crude exports have gone to India, Japan, China and South Korea; another estimate put the eastbound share at 80 percent in the second quarter.^{[4, 5]} A threat to southbound passage therefore obstructs the direction in which the additional Saudi barrels were predominantly traveling.^{[4, 5]}

Northern rerouting preserves barrels but concentrates pressure on Egypt’s limited transit capacity

The northern alternative is real, but it is not elastic. Yanbu shipments toward Egypt’s SUMED pipeline reached 1.8 million barrels a day last week, 66 percent above the previous week and nearly three times the level two weeks earlier.^[4] That surge can be read as proof that Saudi crude is being redistributed rather than lost. It can also be read as evidence that the available escape route is already being used aggressively.^{[4, 10]}

SUMED was reported in April to be operating at its maximum capacity of 2.5 million barrels a day.^[10] Saudi Arabia can also move about 1 million barrels a day through the Suez Canal, but a fully loaded VLCC cannot make the passage.^{[4, 11, 12]} The usual solution is to discharge part of the cargo at Ain Sokhna, pass through Suez at a lighter draft and reload on the Mediterranean side.^{[8, 12]} Each additional diversion therefore consumes pipeline space, terminal handling and ship time. Capacity on paper is not the same as a frictionless barrel delivered.^{[8, 10, 12]}

For Asian buyers, the geometry becomes punishing. A cargo sent north from Yanbu through Egypt, then around the Cape of Good Hope and back toward Asia, could add as much as four weeks compared with the normal route through Bab el-Mandeb.^{[6, 12]} One charterer sought a 54-day one-way option from the Red Sea to South Korea via Suez and the Cape; the estimated extra bunker cost alone was $1.63 a barrel.^[5] The barrel may still arrive, but later and at a higher delivered cost.^{[5, 6, 12]}

Longer voyages shift value from Saudi logistics to tanker operators before exports visibly fall

Those extra days create the clearest near-term beneficiary. VLCC earnings on the Middle East Gulf-to-China route reached $379,000 a day, up almost $85,000 a day since July 6 and carrying a premium of nearly $255,000 a day over Gulf of Oman loadings.^[5] If more Saudi cargoes require longer voyages, the same fleet completes fewer trips over a given period. That tightens effective vessel supply even if the physical number of ships does not change, strengthening freight economics for operators exposed to long-haul crude routes.^{[5, 11, 12, 13]}

The gain is not yet the same as durable earnings. Spot indications must still appear in realized voyage days, freight rates and company results before they support a firm valuation conclusion. Nor has the disruption yet produced a sustained fall in Yanbu exports. The recovery from five to nine Bab el-Mandeb transits shows that avoidance is incomplete, and the rise in SUMED-bound volumes supports the case that flows can be rearranged.^{[3, 4]}

But redistribution is not neutral. Saudi Aramco and its customers must absorb more fuel, freight, insurance and handling somewhere in the chain, even if global supply does not fall.^{[3, 5, 6, 12]} Egypt’s position is mixed: SUMED can gain throughput while the Suez Canal loses traffic.^{[4, 10, 13, 14]} During the earlier Red Sea disruption, trade through the Bab el-Mandeb and Suez chokepoints ran about 60 percent below pre-attack levels, while annual Suez Canal revenue fell 23.4 percent to $7.2 billion from $9.4 billion.^{[13, 14]} Route avoidance can persist long enough to alter earnings across the transport system without eliminating the underlying trade.^{[13, 14]}

The decisive figures are weekly Yanbu loadings, the share of Saudi-linked VLCCs still willing to sail south, and realized SUMED throughput. A material fall below Yanbu’s recent 3.75 million to 4.1 million barrels-a-day range, combined with SUMED holding near 2.5 million, would show that rerouting has become an export constraint rather than a routing inconvenience.^{[4, 6, 10]} If tanker operators then report longer voyages and higher realized rates, the transfer of value from Saudi logistics and Asian delivered costs to shipowners will have reached their income statements. Until then, the proven change is narrower but already consequential: every extra week at sea now consumes part of Saudi Arabia’s effective export flexibility.^{[5, 6, 12]}
