Brent Crude spiked intraday to roughly $109.98 on Friday 11 September 2026, around 6 per cent higher overnight on news of the attack on the Saudi east-west crude line and its highest since early May, then settled the same session at $104.61, down 2.81 per cent ¹. West Texas Intermediate, the US benchmark, settled at $100.05, down 2.37 per cent ².

Both numbers are Friday's, and both close a session that began with the pipeline news. Brent settled at $71.99 on 26 June , and Friday's close sits far above that on the same benchmark. The US Energy Information Administration had raised its forecast for Middle East production shut in during the fourth quarter and pushed its recovery date into 2027 two days earlier, on 9 September .

A spike that unwinds inside a session says traders priced a disruption to a route rather than a loss of barrels. Saudi crude still reaches the water, and the Ministry of Energy has named neither a damaged segment nor a restart date, so the quantity actually removed from the market is unknown to the people pricing it. Futures markets do not trade on Saturday or Sunday. Monday 14 September is the first settlement that can price anything that happened over the weekend.

Deep Analysis

In plain English

Oil is bought and sold on futures exchanges, where a price moves all day and then a single closing figure, the settlement, goes in the record. On Friday 11 September news of the attack on the Saudi pipeline pushed Brent crude, the main global benchmark, up to around $109.98 at one point. By the close it had fallen back to $104.61, which was below Thursday's closing price. The American benchmark, West Texas Intermediate, closed at $100.05. So the market got excited and then changed its mind inside a single day. Exchanges are shut at the weekend, which means anything that happened on Saturday or Sunday has to wait until Monday to show up in a price at all.

The distance between the intraday high and the close is where the risk premium actually sat. Both readings belong to Friday 11 September: a gain of roughly 6 per cent overnight, and a close 2.81 per cent below the previous settlement. On those two published figures, and this is Lowdown's arithmetic rather than a sourced statement, the price finished the day lower than it started it.

A disruption to a route prices differently from a loss of barrels. The Saudi Ministry of Energy has named no damaged segment and no restart date, so the volume actually removed is unknown to the people setting the price, and an unknown outage of a line that was running under capacity is a weak premium to hold overnight.

Exchanges do not settle on Saturday or Sunday. Everything that happened after Friday's close waits for Monday 14 September, which is the first settlement that can carry it.

Consensus view: The US Energy Information Administration, the statistical arm of the Department of Energy, raised its forecast for Middle East production shut in during the fourth quarter to 5.7 million barrels a day on 9 September and moved its recovery date into the second quarter of 2027 . That is a forecast about duration.

Counter-view: The futures market took the opposite view of the same week. Friday's Brent settlement closed 2.81 per cent under the previous one, on the session that opened with the pipeline news, so traders paid less for a barrel at the close than before the attack was known.

Key tension: Whether the settlement reflects confidence that Saudi crude still reaches the water by other routes, or thin conviction going into two days when nobody could trade, which the published prices cannot separate.

This Event

Brent spikes on the strike, then gives it back

The market priced the loss of Saudi Arabia's overland export route and handed most of the move back within one session.

Different Perspectives

Shipping and insurance industry

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Russia and China

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
