U.S. orders limited naval blockade
President Trump ordered a U.S. naval blockade of Iranian ports and coastal areas — a narrower step than closing the Strait of Hormuz but still a major escalation — and the U.S. military said it would begin on Monday. (insidenova.com) Markets reacted nervously and U.S. stock futures fell after the announcement, with reporting linking the move to higher energy‑cost and growth risks. (finance.yahoo.com) At the same time Mr. Trump warned China could face tariffs up to 50% if it were found supplying weapons to Iran, explicitly tying trade penalties to the military confrontation.

President Donald Trump ordered the United States military to stop ships entering or leaving Iranian ports starting Monday at 10 a.m. Eastern. (apnews.com) United States Central Command said the order covers “all Iranian ports on the Arabian Gulf and Gulf of Oman” and applies to vessels of all nations. The command said ships heading to non-Iranian ports would still be allowed to pass through the Strait of Hormuz. (bloomberg.com) Trump had first described a broader move against “any and all Ships” in the strait after United States-Iran talks in Islamabad collapsed over the weekend. The military’s follow-up narrowed that to traffic tied to Iranian ports and coastal areas. (cnbc.com) The distinction matters because the Strait of Hormuz is the waterway between Iran and Oman that carries about one-fifth of the world’s oil. A blockade focused on Iranian ports is narrower than sealing the whole passage, but it still puts commercial shipping, insurance costs and oil prices under pressure. (cnbc.com) Markets reacted before the opening bell in New York on Monday. Dow futures fell about 0.7 percent, Brent crude briefly jumped 9 percent to near $104 a barrel, and West Texas Intermediate rose more than 8 percent above $104 before both benchmarks eased. (finance.yahoo.com) Iran called the move “an act of piracy” and warned it could target Persian Gulf ports if its own energy hubs were threatened. That response added to fears that a shipping restriction could spread beyond Iranian waters. (finance.yahoo.com) Trump also tied the confrontation to trade policy last week. On April 8, he said any country supplying Iran with military weapons would face immediate tariffs of 50 percent, and Reuters reported that warning was aimed in part at China and Russia. (usnews.com) That tariff threat may be harder to carry out than the White House language suggests. Politico reported that a February Supreme Court ruling blocked Trump’s broadest emergency-tariff authority, leaving narrower and slower legal options. (politico.com) For now, the immediate test is at sea. If the United States enforces the order only at Iranian ports, Washington can say it avoided closing the strait outright while still escalating pressure on Tehran. (bloomberg.com)
