Brent Crude eased about 1.7 per cent to $94.71 on 11 June, with WTI near $91.84, on the very day the IRGC declared Hormuz closed to all traffic. The move was a pullback from the $96.34 peak Brent reached on 10 June, and it came after CENTCOM said its strikes were complete. A closure announcement that sends oil down, rather than up, is the market reading the words and discounting them.
A strait genuinely sealed, with enforcement that held, does not let crude fall. Traders priced the IRGC order as rhetoric, weighing it against CENTCOM's denial that transit had stopped and against the absence of any independently verified incident. The "strikes complete" line did the rest, removing the immediate threat of further escalation that had driven the prior day's spike.
Futures and insurance now point opposite ways. The futures market is betting the closure is a declaration that will lapse, while marine insurers are repricing the legal risk of a war-risk zone that exists on paper whether or not a ship is ever stopped. The gap between the two prices is the gap between what the IRGC said and what anyone can confirm it did.
