Brent fell from $110.34 on Wednesday 20 May to $96.14 on Sunday 24 May, a $14 week, with WTI shedding over 6% to $90.30 1. The driver sat next door in the diplomacy: Donald Trump called the Iran deal "largely negotiated" on Saturday 23 May, framing a memorandum of understanding as phase one with the Hormuz-reopening narrative doing the rest 2. The diplomacy sits in the Iran file; the spreads it knocked sit with us.
The Brent-Dubai EFS is narrowing from the $6-plus peak it held in early May , because the light-sweet Hormuz bid deflates faster than sour Dubai, which never carried the same war premium. Brent-WTI is compressing toward $1-2 from the old $4-5 band as WTI catches up. That spread is the one that pays for the trade: above roughly $4 the round-trip economics justify hauling Atlantic barrels east on VLCCs, and below it they stop working. We will not put a precise current EFS print on the page because the assessment is paywalled, but the direction is not in doubt.
The MOU is phase one of a 30-60 day process and leaves the highly-enriched-uranium stockpile untouched 3, so the war premium is discounted, not dead, and a single failed-flow headline re-arms the EFS. The market that ran the long-Brent, short-WTI trade against has watched the Atlantic-basin premium that funded it evaporate inside a week, and the freight complex still reads a war it no longer fully believes in.
