Strait of Hormuz: US Strikes and Burning Tankers Push Oil's War Premium Back Into Play
On Saturday morning, an oil tanker caught fire east of the Strait of Hormuz after striking a naval mine. It was the second mine incident in three days, and it came hours after President Donald Trump confirmed that American forces had carried out what he called "limited" strikes against Iranian air-defence equipment on Qeshm Island. The waterway that carries roughly a fifth of the world's seaborne oil is, once again, a place where ships burn — and the oil market, which spent the week betting on peace, is being forced to reconsider.
The scale of the disruption is hard to overstate. The United Kingdom Maritime Trade Operations centre recorded at least 11 ships attacked in and around the strait in the week ending 6 November, three of which sank. Traffic is running about 65 percent below pre-conflict levels, and IMF PortWatch recorded a single transit on 1 November against a pre-crisis baseline of 85 a day. As of Saturday evening, 147 vessels visible on tracking data were holding position away from berth in the strait and the Gulf. Iran's army says the strait will stay shut until the United States accepts seven conditions; Washington says the mines have been cleared and the waterway is open. Both claims cannot be true, and the ships waiting offshore are the evidence that the market believes neither side completely. On Saturday, US Central Command said an American military aircraft fired on and disabled a commercial vessel in the Gulf of Oman that tried to break the US blockade of Iran.
What makes this week strange is that the oil price fell anyway. Brent crude for January delivery settled on Friday at $98.32 a barrel, up a fraction on the day but down about 13 percent on the week — the steepest weekly drop since 2022, according to Bloomberg figures cited by Rigzone. The contract had settled at $113.43 on 30 October. The market's bet is legible: the Democratic victory in the US midterm elections, plus Qatari mediation, might bring Washington and Tehran toward a settlement, and The Guardian reports that Qatar has put forward a plan under which the strait could reopen as part of an end to the US-Iran war. Traders sold the war premium first and asked questions later. The one day the price jumped — Thursday, up 3.9 percent — was the day reports of fresh tanker attacks reached the tape.
So the market is now holding two incompatible stories at once. In one, diplomacy wins: the strait reopens, the blockade ends, and Brent drifts back toward the $90s or below, where the week's lows already took it. In the other, the shooting continues: more mines, more strikes, and a chokepoint that stays effectively closed while a fifth of the world's oil looks for another route that does not exist. The next two weeks will discriminate between them. The OPEC+ ministerial meeting on 29 November is the next scheduled supply event, and the US inflation print on 10 November will shape the dollar and risk appetite. But the real catalyst is simpler: whether another tanker hits another mine, or whether a Qatari-brokered opening actually materialises.
My read is that the market has moved too far, too fast, toward the peaceful story. The strikes on Qeshm Island are confirmed by the president himself. The mine incidents are confirmed by Iran's own navy, which has no interest in advertising them. The blockade is being enforced with gunfire. None of that is consistent with a strait about to reopen. Peace bets explain a 13 percent weekly drop; they do not explain away burning tankers. I expect the war premium to return before the month is out, and I put a 40 percent chance on Brent settling back above $110 a barrel on at least one trading day before 30 November. The number is deliberately modest: the peace camp has real momentum, the midterm result genuinely changed the politics, and Qatar is a serious mediator. But $110 is only $12 from Friday's close, and it took a single day of tanker headlines to move Brent nearly 4 percent. If the escalation that is already happening keeps happening, $110 is not a stretch. It is the price of the market admitting it sold the risk too cheaply.
