YOGYAKARTA - The negotiation efforts between the United States (US) and Iran failed to reach an agreement. Iran is rumored to still have full control over the Strait of Hormuz. In return, President Donald Trump has repeatedly said that his party will block Iran's maritime traffic. The statement then raised questions about how the US would blockade Iran's ports, namely by restricting the movement of ships.

How the US Blockaded Iran's Ports

As of Monday, April 14, 2026, the US military began a blockade of the Strait of Hormuz. The move began at 21:00 local time. The blockade itself is carried out against ships entering and leaving Iranian ports and coastal areas, as explained by the US Central Command (Centcom), quoted from BBC, Tuesday, April 14.

The same thing was said by the British Maritime Trade Operations Agency. According to information, the Americans blockaded the entire Iranian coastline, including port facilities and energy infrastructure, reported by AP News, Tuesday, April 14.

The blockade carried out by the Americans then created a considerable confrontation. The impact is said to be widespread and affect the global economy.

In response to the blockade, the Iranian Revolutionary Guard warned that military vessels approaching the strait would be considered in violation of the ceasefire agreement. Iran is also not afraid to take strong and firm action.

Impact of US Blockade on Iran

The blocking of Iranian oil shipments has sparked widespread concerns. Reported by Reuters, the blockade could drastically cut off oil supplies.

As is known, Iran is a crude oil exporter of 1.84 million barrels per day (bpd) in March. This means that Iran's crude oil export figures will certainly have an impact on the rise in global oil prices later.
