Key takeaway

Nine months of supply chain damage is locked in regardless of when the war ends.

Brent crude closed at $112.57 on 28 March, up 4.22% on the day. Pre-war Brent was $67.41; the current price represents a 67% increase in 29 days. The Houthi entry and Iran's firm rejection of negotiations drove the reversal. 1

The IEA's record 400 million barrel emergency release, the largest in the agency's 50-year history, has not stabilised prices. The IEA itself said why: "The most important factor is resumption of regular transit through the strait of Hormuz." 2 European reserves are predominantly industry-held: 74.8 million barrels from industry versus 32.7 million from government, giving European governments less direct control than the headline figure implies.

Dow CEO Jim Fitterling stated the damage is already locked in: even if Hormuz reopens tomorrow, petrochemical supply chains will take 250-275 days to unwind. The US-Asia petrochemical pricing gap has surged from under $500 to over $1,200 per metric tonne. 3 US farmers face a 2 million tonne urea shortfall during spring planting, with urea prices up 49% to $720 per tonne. Corn and wheat yields on affected fields could fall 10-20%, with downstream effects on global grain prices by autumn.

Deep Analysis

In plain English

Oil prices closed at $112.57 per barrel on 28 March, up about 4% on the day. Before the war started, a barrel cost $67.41. The 67% rise in 29 days is one of the fastest sustained oil price increases in modern history. The IEA, a group of oil-consuming countries, released the largest emergency oil reserve in its history: 400 million barrels. It has not reduced prices. The IEA itself said why: reserves cover a temporary supply disruption; they cannot substitute for a closed shipping route. For a British driver, $112 oil means roughly £1.80 per litre at the pump. For farmers, fertiliser is the bigger problem. Urea, the chemical used to grow corn and wheat, has risen 49% in price and the US faces a 2 million tonne shortage this spring planting season. Crop yields could fall 10-20%, and those effects will reach food prices by autumn.

What could happen next?
  • Consequence

    A ceasefire today does not end the economic damage: Dow's 250-275 day supply chain unwind means petrochemical-driven inflation persists into Q1 2027 regardless of conflict resolution.

  • Risk

    The 2 million tonne urea shortfall is not substitutable within a planting season; US crop yields in autumn 2026 are already compromised regardless of war outcome.

Different Perspectives
Markets
Markets
Brent crude rose 2.2 per cent to $96.34 on 10 June, reversing a 7 per cent weekly decline built on deal optimism, as the overnight exchange repriced the Strait of Hormuz risk premium in a single session. The move reflects transit-risk repricing rather than supply shock: Iran's exports had already collapsed to below 300,000 barrels per day.
Pakistan
Pakistan
Pakistan's Naqvi channel, the only mediation track carrying both civilian and military buy-in, was stress-tested by live ordnance within 48 hours of the 6-7 June Tehran visit. Whether Washington informed Islamabad of the imminent strike plan while Naqvi was in Tehran remains undisclosed, putting the channel's neutrality under scrutiny.
Kuwait
Kuwait
Kuwait hosted the third Iranian strike on its soil since the 3 June airport drone attack, with Ali Al Salem airbase targeted in the three-country salvo. Its recent $1.98 billion Anduril Anvil counter-drone purchase signals it is rearming rather than reconsidering its hosting posture.
Bahrain
Bahrain
Bahrain absorbed the IRGC barrage via PAC-3 intercepts with its magazine already at 87 per cent depletion and no resupply before 2027. Sounding air-raid sirens over Manama, it faced the intercept burden with the thinnest defensive stack in the Gulf coalition.
Jordan
Jordan
Jordan reported all five incoming missiles intercepted with no injuries and no damage, a clean defensive performance that strengthens Amman's case for staying in the Western coalition without escalating its own posture. It now sits on Iran's target list for the first time despite not being a party to the Abraham Accords confrontation.
Iran / IRGC
Iran / IRGC
Foreign Minister Araghchi posted on X that US forces should 'leave our region if you want to be safe' and framed the exchange as a US defeat, while the IRGC claimed 21 targets hit and an F-35 hangar destroyed. The claims serve a domestic and Arab-audience framing rather than a verified battle-damage assessment.
