Brent Reverses $10 After CENTCOM Narrows Hormuz Blockade to Iranian Ports

The Scope Downgrade

Trump announced Sunday night that the U.S. Navy would blockade the Strait of Hormuz, targeting "any and all Ships from trying to enter, or leave." Markets gapped higher: Brent crude jumped more than 7% to above $103 per barrel by Monday morning, with WTI surging nearly 8% past $104.

Then CENTCOM published the operational details. The blockade would enforce restrictions on "ships entering or leaving Iranian ports" but "will not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports." That is a fundamentally different operation. A full Hormuz closure threatens roughly one-fifth of global oil consumption — approximately 20 million barrels per day flowing from Saudi Arabia, Kuwait, Iraq, the UAE, and Qatar. The Iranian-port-only version targets the residual trickle of Iranian exports, most of which the war had already disrupted. The incremental supply threat that justified Monday's opening gap was far smaller than the headline implied.

Why the Premium Unwound

Three forces converged to reverse the spike.

First, the CENTCOM scope clarification defused the worst-case scenario. Non-Iranian Gulf producers — Saudi Aramco, ADNOC, Kuwait Petroleum — can still ship through the strait, which means the blockade does not compound the existing supply shock the way a full closure would.

Second, the market interpreted the blockade as negotiating leverage, not terminal escalation. Mark Luschini at Janney Montgomery Scott called it "probably a little bit more brinkmanship than necessarily the start of a significant re-escalation," noting the two-week ceasefire was still theoretically in effect. Officials separately reported "forward motion on trying to get to an agreement."

Third, the blockade was fully telegraphed. Navy destroyers entered the strait on April 11 for mine-clearing operations with underwater drones, and Trump's announcement came Saturday night. By the time enforcement began at 10 AM ET Monday, the trade was loaded. Brent settled around $98 — still up on the day, but $5 below the intraday high. The BRENTOIL perp, trading 24/7 with leverage, sold further to $93.

What the Deficit Math Says

The selloff does not mean the oil market is loose. A Reuters poll of eight analysts projects a 750,000 barrel-per-day deficit for 2026, flipping from the 1.63 million bpd surplus forecast last September. Q2 is the worst stretch, with the deficit expected to average around 3 million bpd. ANZ Bank estimates roughly 9 million bpd of crude supply has been removed since the conflict began on February 28, with 136 million barrels of crude and products still stuck inside the Gulf.

The deeper issue is that even a peace deal does not instantly restore flows. Erik Meyersson at SEB noted that the blockade is "an admission that the ceasefire's central premise — the reopening of the Strait — is untenable for now." Physical dated Brent was trading near $150 per barrel earlier in the week, a record premium over paper futures. Morgan Stanley held its Q2 Brent forecast at $110 and its Q3 at $100. The structural deficit has not changed — what collapsed today was a single-session war premium built on a headline that turned out to be louder than the underlying operation.
