UPDATE — this extends our earlier coverage: Hormuz Shipping Traffic Thins Further as US Signals New Iran Pressure

Donald Trump says he will declare the Strait of Hormuz United States territory. The threat came Friday at a rally in New York, where the president vowed to "finish defeating" Iran, according to France 24.

That marks an escalation from the blockade pressure covered in our earlier report, when tanker traffic through the strait was already thinning as Washington signalled a tougher line on Tehran. Iran rejected the new claim on Saturday: Deputy Foreign Minister Kazem Gharibabadi said the waterway "will remain Iranian" and can be opened or closed only at Iran's command, per France 24.

Why it matters: any American attempt to assert sovereignty over the strait — militarily or otherwise — risks direct confrontation with Iran, with knock-on effects for oil prices, shipping insurers and the wider region.

Trump has not said how a declaration would be enforced, and Iran controls the strait's northern shore. Whether Washington backs the claim with military posture, and how oil markets respond, is the open question.
