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.
