Brent fell to about $91 in late May 2026, down roughly 19 per cent on the month on optimism over a ‘largely negotiated’ deal. The deflation from the $126 peak separates two risks that were previously bundled: about $35 of war-and-blockade premium has left, while roughly $20 a barrel of institutional premium stays. That residual — about $2 billion a day — is the price of the institutional gap, now visible directly in the crude strip.

Brent rose about 3.8 per cent on 4 May 2026 after the Project Freedom announcement and an Iranian missile claim, after pulling toward $108 earlier in the week on peace-proposal hopes. Earlier posts have documented the chokepoint risk premium as a level. This post documents it as a volatility — a directly priced cost in hedging premia, surcharge widths, insurance loadings, and rate-case adjustments that accrues every day the institutional state of the chokepoint is undefined.

Brent touched $126 overnight on April 30 — highest since 2022 — before pulling back to about $114. Both halves of the move are informative. The spike priced an option that the Iranian new-chapter announcement and the US blockade extension might converge into further escalation; the pullback un-priced part of that option as the news cycle settled. The chokepoint risk premium is now the marginal component of global crude price.

Brent closed at $118 and WTI at $107 on April 29 after Trump said the US blockade of Iran will continue until a nuclear deal. US gasoline is forecast at $4.30/gal for the month. Walking a single gallon back to the tanker shows the chokepoint fee is small. The chokepoint risk is what is doing the work in your fill-up.

The US Iran ceasefire expires Wednesday 22 April. Iran says no talks planned. US delegation heading to Islamabad regardless. Brent up 7 percent Monday morning. Three scenarios cover the realistic outcome space, and all three leave the institutional vacuum at Hormuz unchanged. The real signal this week is at Northwood, not Islamabad.

At 19:00 GMT on Friday, Iran’s foreign minister declared the strait ‘completely open’ for the ceasefire. By Saturday morning, the IRGC said control had returned to ‘its previous state.’ Brent crude traded 11.5 percent below Thursday in the interim. The whipsaw is exactly what an institutional authority is designed to prevent.
