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
IAEA
IAEA
Director General Rafael Grossi appeared in person at the UNSC on 19 May and warned that a direct hit on an operating reactor 'could result in very high release of radioactivity'. The session produced a condemnation record but no resolution, and the Barakah perimeter was already struck on 17 May.
Hengaw (Kurdish rights monitor)
Hengaw (Kurdish rights monitor)
Hengaw documented three judicial executions and the detention of Kurdish writer Majid Karimi in Tehran on 19 May, establishing Khorasan Razavi province as the newest geography in Iran's wartime judicial record. The organisation's Norway-based operation continues to surface a domestic repression track running in parallel with every diplomatic and military development.
India
India
Six India-flagged vessels conducted a coordinated cluster transit under PGSA bilateral assurances during the 17 May window, paying no yuan tolls. New Delhi's inclusion in Iran's state-to-state passage track insulates Indian energy supply without requiring endorsement of the PGSA's yuan-toll architecture or alignment with the US coalition.
Pakistan
Pakistan
Pakistan is the only functioning diplomatic bridge between Tehran and Washington. Its role is relay, not mediation in the settlement sense: it conveyed Iran's 10-point counter-MOU in early May, relayed the US rejection, and is now passing 'corrective points' in the third documented exchange of this sub-cycle without either side working from a shared text.
UK and France (Northwood coalition)
UK and France (Northwood coalition)
Twenty-six coalition members have published no rules of engagement eight days after the Bahrain joint statement; Lloyd's underwriters have conditioned war-risk reopening on written ROE from either Iran or the coalition. Italian and French mine-countermeasures deployments are operating on the in-water clearance task CENTCOM Admiral Brad Cooper's 90% mine-stockpile claim does not address.
Saudi Arabia
Saudi Arabia
Riyadh has not publicly commented on the Barakah strike or the 50-47 discharge vote. Saudi output feeds the IEA's $106 base case; the $5 Brent premium above that model reflects institutional uncertainty no Gulf producer can compress through supply adjustment alone.
