Iran says Hormuz open to shipping, Trump says US blockade remains

Iran said on April 17 the Strait of Hormuz is open to commercial shipping; President Donald Trump said a U.S. naval blockade still stands.

The strait carries roughly a fifth of the world’s petroleum shipments, so any disruption can ripple through global energy prices and trade routes. A clear signal from Tehran or Washington can influence insurers, ship owners, and governments that rely on the waterway for oil imports and exports. Analysts at major energy firms said that any perceived threat to Hormuz could push Brent crude prices higher, as traders factor in supply risk.

Iranian officials said the strait is open to commercial shipping. They said the recent cease‑fire agreement with the United States permits normal commercial traffic through the channel. Iran said the strait was effectively sealed after the 2024 regional skirmishes, and this declaration marks its first official reopening. The ministry of foreign affairs released a statement on Thursday urging regional partners to resume regular shipping schedules.

The White House, however, said the United States continues to enforce a naval blockade pending clarification of the cease‑fire terms. President Donald Trump said a U.S. naval blockade still stands. The administration said that existing U.S. sanctions on Iranian oil shipments remain in place, complicating any immediate de‑escalation. A senior defense official said that U.S. warships remain positioned to interdict vessels that do not comply with American directives.

Shipping companies have responded with mixed signals. Some operators said they will send tankers through Hormuz, citing the Iranian declaration, while others have postponed voyages, citing the U.S. stance. Insurance premiums for voyages in the region have risen modestly since the divergent statements, reflecting heightened perceived risk. By Friday, Brent futures had risen $1.20 per barrel^[1], reflecting market anxiety over the contradictory statements.

Independent observers have not yet confirmed the operational status of either side’s naval assets in the strait. The dispute hinges on differing interpretations of the cease‑fire agreement. Analysts said the low confidence rating of 35 percent^[1] attached to the reports, indicating that the situation remains fluid and facts are still emerging. Diplomatic channels in Geneva are reportedly working to clarify the language of the cease‑fire, but both sides have offered limited public comments.

What this means: The conflicting messages create uncertainty for global oil markets and for nations dependent on Hormuz‑bound shipments. Until the United States and Iran reconcile their interpretations of the cease‑fire, shippers may face volatile routing decisions, and price volatility could persist.
