US Central Command confirmed it will begin enforcing a blockade of all maritime traffic entering or exiting Iranian ports and coastal areas, including facilities on both the Arabian Gulf and Gulf of Oman. The blockade takes effect at 10:00 AM Eastern Time (14:00 GMT) today. CENTCOM clarified that vessels transiting the Strait of Hormuz between non-Iranian ports will retain freedom of navigation — a significant distinction from President Trump's initial announcement, which suggested all ships in the strait would be subject to interdiction.
This discrepancy between Trump's social media statements and CENTCOM's operational guidance creates immediate confusion for commercial shipping. Trump stated the US Navy would "seek and interdict every vessel in International Waters that has paid a toll to Iran." CENTCOM made no mention of toll payments or interdiction of third-party vessels. Whether this reflects a deliberate walk-back, bureaucratic correction, or simply poor coordination between the White House and the military remains unclear — but shipping companies cannot afford to guess.
The blockade represents a dramatic escalation from the two-week ceasefire that had been holding. It is, in practical terms, an act of war under international law — naval blockades have historically been treated as such. The US is betting that Iran will absorb this pressure without retaliating in ways that break the ceasefire entirely.
