Key takeaway

Markets are pricing prolonged war, not imminent resolution.

Brent Crude advanced above $116 per barrel on 30 March, approximately 72% above its pre-war level of $67.41. 1 The monthly gain is heading for a record. Goldman Sachs maintained a $14 to $18 per barrel geopolitical risk premium is baked into the price. Global stock markets extended their selloff as Houthi entry and the US military build-up stoked prolonged-conflict fears.

The price trajectory tells the story of a market that has abandoned hope of a quick resolution. Brent settled at $112.57 on 28 March , already elevated by Houthi entry. Trump's oil seizure statement, the third consecutive Houthi attack on Israel, and Pentagon confirmation of ground operations planning pushed it above $116 two days later.

AIS tracking data paints a bleaker picture than headline prices suggest. Shadow fleet vessels account for 80% of Hormuz transits in March, up from 15% in February . Legitimate commercial traffic has effectively stopped: approximately three transits per 24 hours against a pre-war baseline of 138. The Hormuz 'reopening' is a reorganisation of traffic to benefit non-US-aligned operators, denominated in yuan, under IRGC naval supervision.

The 6 April deadline for Trump's power plant strike threat is six days away. If the deadline passes without diplomatic movement and the 82nd Airborne stages forward from Kuwait, Goldman's risk premium estimate will need revision upward. Every dollar on Brent translates to approximately 2.5 pence per litre at UK petrol pumps within a week.

Deep Analysis

In plain English

Brent crude is the main international benchmark for oil prices. Before the war started, a barrel of oil cost $67. By 30 March it cost over $116. That is a 72% increase in one month. Higher oil prices feed through into everything: petrol and diesel costs, heating bills, the price of food and goods that are transported, and the cost of making plastic and chemicals. The monthly increase is on track to be the largest in recorded history. Goldman Sachs, the US bank that tracks commodity prices, says there is an extra $14 to $18 on every barrel just because of the war risk. The closer US ground forces get to Iran's oil export terminal at Kharg Island, the higher the risk premium is likely to rise.

What could happen next?
  • Risk

    The 6 April power plant strike deadline, with no diplomatic movement, risks a further price spike beyond Goldman's current risk-premium estimate if Trump follows through.

  • Consequence

    The IEA's 400 million barrel emergency release has not stabilised prices. Markets are treating this as a structural supply disruption, not a temporary spike amenable to reserve releases.

Different Perspectives
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Israel
Israel
IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
Qatar
Qatar
Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.
Kuwait
Kuwait
Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.
United States
United States
Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
