Brent peaks at $126 — record war high

Oil prices have nearly doubled since the war began, driven by the largest supply disruption the IEA has ever recorded. Strategic reserve releases bought days, not weeks.

Key takeaway

At $114 settled, markets are pricing a durable disruption — the IEA's four-day reserve buffer confirms this.

Brent Crude peaked at $126 per barrel this week before settling around $114 — a 70% increase over the pre-war price of $67.41. The trajectory has been unbroken: $100.21 on 16 March, $108.65 three days later after Netanyahu claimed Israel was helping reopen Hormuz, $112.19 by Thursday, and now a new spot high. Bloomberg had already reported a record $14.20-per-barrel backwardation — the premium buyers pay for immediate physical delivery over next-month futures — meaning refiners were effectively paying $126 or more for delivered crude before the headline price caught up.

The International Energy Agency's March report documented the cause: global output down 8 million barrels per day, Gulf production curtailed by at least 10 million bpd including condensates — the largest supply disruption in the agency's history⁠1. IEA member states responded with a 400 million barrel coordinated drawdown from strategic petroleum reserves, the largest ever. That volume covers roughly four days of global consumption. The IEA called it "a stop-gap measure" without swift conflict resolution⁠2. The IRGC's toll system at Hormuz — 89 to 90 vessels transited under Iranian clearance in the first half of March, at fees up to $2 million per passage — has replaced a military blockade with selective commercial control, but it has not restored the volume that moved freely before 28 February⁠3.

The supply-side interventions the Trump administration has attempted have not altered the price curve. The Treasury's waiver on 140 million barrels of sanctioned Iranian crude already on tankers equals 1.5 days of global consumption. The Venezuela authorisation and 60-day Jones Act waiver address distribution, not the underlying shortfall. Charter rates have quadrupled to $800,000 per day, and war-risk premiums on very large crude carriers run between $3.6 million and $6 million per voyage⁠4. These costs compound through the supply chain before reaching consumers.

The distance to the next threshold is shrinking. Daan Struyven, Goldman Sachs's head of oil research, warned earlier this week that Brent could exceed its 2008 all-time intraday record of $147.50 if Hormuz flows remain depressed for 60 days. Ann-Louise Hittle of Wood Mackenzie forecast $150 "soon," with $200 "not outside the realms of possibility". Oxford Economics assessed that $140 per barrel triggers a mild global recession at negative 0.7% GDP⁠5. At the current rate of increase — roughly $6 per barrel per week since the war began — that threshold arrives in late April without a change in supply conditions.

Deep Analysis

In plain English

Oil is priced on global markets where traders buy and sell futures contracts. When they believe a supply cut will last months rather than days, they push prices up immediately to reflect future scarcity. The $114 settled level — still 70% above pre-war — signals traders do not expect a quick resolution. The $126 peak captured the moment of maximum uncertainty. The partial retreat to $114 reflects some hope that diplomacy or reserve releases might partially offset supply loss — not that the crisis is resolving. The distinction matters: a settled high price is more economically damaging than a spike, because businesses and households cannot plan around it.

Deep Analysis
Synthesis

The IEA releasing 400 million barrels to cover four days of global consumption exposes a fundamental inadequacy in the strategic reserve architecture. That architecture was designed for brief supply shocks — 1970s-scale embargoes lasting weeks — not sustained chokepoint blockades of indefinite duration. The mismatch between available tool and disruption scale is now fully visible to markets.

Root Causes

Decades of underinvestment in bypass infrastructure left Hormuz structurally irreplaceable. The UAE's Habshan–Fujairah pipeline handles roughly 1.5 million bpd — under 10% of normal Hormuz throughput. No comparable alternative route exists for LNG or condensate flows, which cannot be rerouted via pipeline at all.

Escalation

The $12 retreat from $126 to $114 is fragile. Any Iranian strike on Saudi Aramco facilities or UAE terminals — explicitly included in the Khatam al-Anbiya counter-threat — could push prices through the $140 recession-triggering level within a single trading session.

What could happen next?
  • Risk

    If Iran executes counter-strikes on Gulf energy infrastructure, $126 becomes a price floor rather than a ceiling.

    Immediate · Assessed
  • Consequence

    The IEA reserve release exhausts the primary coordinated institutional buffer, leaving no further tool available short of conflict resolution.

    Short term · Assessed
  • Risk

    Tanker insurance markets may move toward blanket war-risk exclusions, rendering transit commercially impossible regardless of IRGC toll arrangements.

    Short term · Suggested
  • Precedent

    A sustained Hormuz blockade will accelerate long-term investment in bypass pipeline and LNG infrastructure outside the Gulf, permanently reshaping energy trade routes.

    Long term · Suggested

Different Perspectives
United States (Joint Maritime Information Center)
United States (Joint Maritime Information Center)
The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.
United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.
Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.
Qatar (mediators)
Qatar (mediators)
Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.
Korea Shipowners' Association
Korea Shipowners' Association
The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.
Kuwait (foreign ministry)
Kuwait (foreign ministry)
Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
