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
Oil markets / Lloyd's of London
Oil markets / Lloyd's of London
Brent fell approximately 5% to $82.98 and WTI to $80.89 as markets priced a reopening; the Nikkei rose 5% and Kospi 5.5%. Lloyd's has not de-listed Hormuz from its war-risk register; the UAE assessed full flows will not resume before 2027; markets priced the announcement, not new barrels.

The IAEA declared loss of continuity on Iran's 440.9 kg HEU stockpile after 97 days without inspector access since 28 February 2026; Grossi replied to Araghchi's materials-protection letter citing Iran's NPT Safeguards Agreement obligation to declare any nuclear transfer. The agency has treaty text and no inspectors on the ground to enforce it.
Qatar mediators
Qatar mediators
Qatari negotiators flew to Tehran to close remaining gaps, operating as the primary shuttle channel to bridge the civilian-track gap the IRGC veto left. Qatar's Hormuz mediation role is its most significant since the April ceasefire; the Lebanon clause is the unresolved obstacle neither shuttle can force.
Pakistan mediators
Pakistan mediators
Pakistan's channel, which delivered the April ceasefire after an identical public-denial cycle, has not secured a written IRGC or Khamenei response to the MOU. The Pakistan-Qatar shuttle insists the deal covers Lebanon; neither has a mechanism to bind Israel to a clause Israel has now formally repudiated.
India / Modi
India / Modi
Modi confirmed a G7 bilateral with Trump on 17 June after two formal Indian protests over the CENTCOM strike on the MT Settebello that killed three Indian sailors; Jaishankar phoned Rubio with a strong protest on 13 June. India is the first non-party leader to put the blockade's human cost on a formal G7 agenda.
Israel / Netanyahu cabinet
Israel / Netanyahu cabinet
Defence Minister Katz declared the IDF stays in Lebanon, Syria and Gaza for an unlimited period; Ben-Gvir said the deal does not bind Israel. Israeli strikes on Beirut forced the signing to slip to 19 June; Trump called Netanyahu 'a very difficult guy' and said the strikes nearly derailed the deal.
