US naval blockade of Iranian ports takes effect after failed talks

The United States Central Command began enforcing a naval blockade on all maritime traffic to and from Iranian ports on Monday at 10 a.m. Eastern Time, following the collapse of negotiations between US and Iranian officials in Islamabad.

The move came hours after nearly 21 hours of talks between US Vice President J.D. Vance and Iranian representatives ended without agreement. Vance said the main obstacle was Iran’s refusal to commit to abandoning its nuclear weapons ambitions. Iranian state media reported that both sides failed to resolve key differences.

Donald Trump had earlier stated that the US Navy would block all vessels attempting to enter or exit the Strait of Hormuz. However, the official order from CENTCOM narrowed the scope. The blockade applies to ships entering or leaving Iranian ports and coastal zones but does not restrict vessels transiting the strait to non-Iranian destinations. This distinction allows continued passage for Gulf-bound shipping while isolating Iranian maritime trade.

Mohammad Bagher Ghalibaf responded with a warning that further escalation could trigger a sharp and accelerating rise in global oil prices. In a message shared online, he suggested that supply disruptions could lead to a nonlinear surge in fuel costs driven by shortages, speculation, and market reactions. He warned that US gasoline prices could climb significantly if tensions intensify.

Markets reacted immediately. US benchmark crude rose about 8 percent to around $104 per barrel, while Brent crude surpassed $101. Asian stock markets declined, with major indices in Tokyo, Seoul, and Sydney falling between 1.5 and 2.8 percent. India’s Sensex dropped more than 1,500 points, or about 2 percent, in early trading.

The future of the current ceasefire, set to expire on April 22, remains uncertain. Vance said a final proposal had been presented to Iran, with Washington awaiting a response.
