On April 13, 2026, the United States announced that it will begin a maritime blockade on Iranian ports at 10:00 am ET (5:00 pm Pakistan Standard Time).
The decision was confirmed by US Central Command (CENTCOM) under instructions linked to US President Donald Trump. The move has increased tensions in the Gulf region and raised global concern over possible disruptions to oil trade.
The US military said the blockade will cover all Iranian ports and coastal entry and exit points. This includes ports in the Arabian Gulf and the Gulf of Oman. According to the announcement, the rule will apply to ships from all countries without discrimination. The main goal is to stop Iran’s oil exports and apply pressure on its economy.
At the same time, CENTCOM clarified that ships passing through the Strait of Hormuz will not be blocked as long as they are not traveling to or from Iranian ports. However, officials warned that the situation remains sensitive and could change depending on developments on the ground.
US authorities also issued warnings to the global shipping industry. Commercial vessels have been advised to follow official “Notice to Mariners” updates and stay in contact with US naval forces when operating in nearby waters. This warning has created concern among shipping companies due to possible risks in the region.
President Trump defended the decision and said the blockade would be highly effective in stopping Iran from selling oil. He also said that international partners are supporting efforts to limit Iran’s oil exports. Trump further repeated his position that Iran will not be allowed to develop nuclear weapons under any circumstances.
Iran reacted strongly to the announcement. Parliament Speaker Mohammad Bagher Ghalibaf mocked the decision and warned that fuel prices could rise globally as a result. He suggested that people may soon miss lower fuel prices if the situation continues.
Ghalibaf also said Iran would not accept threats and would respond if forced into conflict. At the same time, he said Iran is open to logic-based dialogue but will not bow to pressure from other countries.
The situation has created fresh uncertainty in global energy markets. With major shipping routes and oil supply lines involved, experts warn that even small disruptions could affect fuel prices worldwide. As tensions rise between the United States and Iran, the world is now watching closely for further developments.
