Trump declares Strait of Hormuz open as commercial traffic tells a different story

President Donald Trump declared the Strait of Hormuz “very functioning” on August 27, claiming the US has established greater control over the critical waterway and dismissing Iran’s response to the situation as mild. The only problem with that framing: an oil tanker was struck by an unidentified projectile in the strait on the same day he made those comments.

Commercial traffic through the world’s most important oil chokepoint has collapsed to roughly a dozen vessels per day. That’s down from a pre-conflict norm of around 130 daily transits, a decline of more than 90%.

What Trump actually said

Speaking on August 27, Trump described the strait as operational and insisted that any mines in the waterway had been cleared. He acknowledged limited drone and rocket threats but framed them within a broader narrative of US naval dominance in the region.

A day later, on August 28, Trump doubled down. He stated the US maintains control over the strait and has no intention of entering into renewed talks with Iran.

Iranian officials have insisted they will not fully reopen the strait until the US lifts sanctions and ends what Tehran characterizes as a blockade on Iranian ports. A deal that had been struck in June, which addressed sanctions relief in exchange for reinstated maritime security, has since lapsed with no replacement in sight.

The numbers don’t support the narrative

Roughly 20% of the world’s petroleum passes through the Strait of Hormuz under normal conditions. When traffic drops from 130 vessels a day to about 12, the supply chain implications ripple across global energy markets.

Brent crude prices climbed above $91 per barrel in mid-August, reflecting the market’s assessment that the strait is anything but fully operational.

For context, the strait connects the Persian Gulf to the Gulf of Oman and the broader Indian Ocean. Oil producers including Saudi Arabia, Iraq, Kuwait, and the UAE depend on it as their primary export route.

Diplomatic channels, mostly frozen

While Trump has ruled out direct US-Iran talks, reports indicate that Iran and Oman have been engaged in bilateral negotiations covering territorial and revenue-sharing issues related to the strait and surrounding waters. As of late August, no agreements had been finalized.

The lapsed June deal had provided a framework for sanctions relief tied to maritime security guarantees. Its collapse means both sides are back to a posture of coercion rather than compromise. Iran’s position is that the strait stays constrained until sanctions come off. Washington’s position is equally clear: no concessions, no meetings.

What this means for markets

Oil markets are already pricing in sustained disruption. With Brent above $91, the premium reflects both current supply constraints and the risk of further escalation.

Trump’s characterization of the situation as mild may serve a domestic political purpose, but the shipping data, oil prices, and ongoing tanker attacks suggest the Strait of Hormuz crisis is far from resolved. The gap between rhetoric and reality is measured in about 118 missing ships per day.
