US CENTCOM Orders Full Blockade of Iranian Ports, Sending Oil Prices Soaring After Failed Pakistan Talks

AI Summary
The U.S. military announced a comprehensive blockade of all Iranian ports effective April 13, citing the collapse of peace negotiations in Pakistan. The move excludes non‑Iranian traffic through the Strait of Hormuz but sparked an 8% jump in U.S. crude and a 7% rise in Brent, underscoring heightened geopolitical and market volatility.

The United States military confirmed that, beginning at 10 a.m. Eastern Time (14:00 GMT) on April 13, all maritime traffic entering or leaving Iranian ports will be blocked. The directive, issued by U.S. Central Command (CENTCOM), targets vessels of every nation operating in the Gulf and the Gulf of Oman, but explicitly excludes ships merely transiting the Strait of Hormuz to non‑Iranian ports, marking a narrower scope than former President Donald Trump’s broader strait‑wide threat.

This decisive action follows the abrupt end of marathon peace talks in Islamabad, where negotiators failed to secure a memorandum of understanding with Tehran. The stalemate has revived fears of renewed hostilities, prompting the U.S. to leverage maritime pressure as a bargaining chip.

Financial markets reacted sharply: U.S. crude oil prices surged 8 % to $104.24 per barrel, while the benchmark Brent crude rose 7 % to $102.29. The spikes reflect investor anxiety over potential disruptions to the flow of oil and liquefied natural gas that currently passes through the Strait of Hormuz, a chokepoint responsible for roughly one‑fifth of global energy shipments.

Since the February 28 launch of a joint U.S.–Israel operation against Iran, the strait’s traffic has dwindled to a trickle. Iran continues to navigate its own vessels and has allowed limited passage for foreign ships, while discussing a post‑conflict toll system for the waterway.

In response to the blockade threat, Iran’s Islamic Revolutionary Guard Corps warned that any U.S. warship attempting to enforce the measure would breach the existing U.S.–Iran ceasefire—set to expire on April 22—and would be "dealt with severely."

Iranian Foreign Minister Abbas Araghchi blamed the United States for the diplomatic failure, accusing U.S. negotiators of "shifting the goalposts" when a deal was "just inches away."

Academic commentary echoed regional concerns. Zohreh Kharazmi, an associate professor at the University of Tehran, asserted that the United States "is not in a position to dictate" Iranian maritime movements and warned that a prolonged standoff would quickly reveal which side—"the resilience of the Islamic Republic or the resilience of global markets"—would suffer first.

While the blockade targets Iranian ports, CENTCOM emphasized that it will not impede freedom of navigation for vessels merely passing through the Strait of Hormuz, a subtle but significant concession aimed at avoiding a full‑scale maritime confrontation.
