The blockade targets vessels of all nations entering or leaving coastal areas or ports in Iran, not the Strait of Hormuz itself.

The German government emphasized this distinction, with spokesman Stefan Kornelius saying the Strait of Hormuz does not mark the end of the diplomatic process.

More than 10,000 sailors, Marines and Air Force personnel are involved.

In the first 24 hours, six merchant ships complied with US orders to turn around.

Economic Impact and Global Reaction

The blockade threatens to cut off more than 90% of Iran's economy, which is fuelled by international trade by sea.

Miad Maleki estimated the blockade could cost Iran approximately $435 million a day.

Oil prices surged to $104.24 per barrel before easing on hopes of further talks.

China condemned the blockade as a dangerous and irresponsible act.

The IMF cut its global growth forecast to 3.1% for 2026.

The blockade risks straining Washington's ties with countries such as China and India.

Diplomatic Signals and Negotiation Prospects

The White House signaled a diplomatic off-ramp despite the blockade.

Trump said the next round of talks could take place over the next two days.

Officials were internally discussing a potential second, in-person meeting before the ceasefire expires.

The blockade was described as a pressure tactic to increase the temperature on Iran.

Tehran considers the blockade a violation of the ceasefire.

Abas Aslani said it can complicate the situation.

Legal and Strategic Challenges

The blockade raises complex questions about international law and risks of escalation.

Retired Canadian vice-admiral Mark Norman called it a somewhat desperate act.

The US military would have to establish patrol areas outside of the gulf to intercept vessels.

Experts say it is unlikely the US would fire missiles at tankers.

The most likely option is to force vessels to change course and launch armed boarding parties if needed.

The blockade comes amid a fragile two-week ceasefire.
