Strait is a strategic area for transporting 20% of global oil and place of passage is small and can be easily blocked if Iran wants
The Iranian Parliament on Sunday (22.jun.2025) the closure of the Ormuz Strait, according to local media. The site is the main export route of Persian Gulf countries, including Saudi Arabia, United Arab Emirates, Oman, Iraq and Kuwait.
The decision still needs to be approved by the Supreme National Security Council and the supreme leader Ali Khamenei. The United States use its influence to prevent the closure of the channel.
The narrow connects Oman’s Gulf to the Persian Gulf. The region is 33 kilometers wide at its tighter point -between the Musandam peninsula in Oman, and Iran. As a comparison, this distance is almost half of the city of São Paulo, which measures 70 km.
Once in the narrow, the ships do not move freely. The vessels navigate 2 sea corridors, input and exit, each 3 kilometers wide. It’s like a road in the two -way sea.
Traffic channels were established internationally to avoid accidents. The track that separates the two corridors also measures 3 kilometers.
As the areas are narrow and predictable, Iran can prevent vessels from passing naval mines. They can be released by submarines, other ships or helicopters.
Another possible Persian country strategy is the use of anti -evil missiles, such as the. These high -range devices can reach vessels in the ocean, and can be hidden in the coastal mountains around the channel.
Barrel
For experts, the sea is the most important in the world in the oil market. There, they are from 17 million to 21 million barrels a day, according to the. This represents 20% to 30% of world consumption. Prior to the decision of the Parliament of Iran, the future quotation for September 2025 of the Brent Oil was US$ 75,48. Or WTI, by August 2025, was from US$ 74,93.
“If this block confirmed, the oil barrel can go from $ 120 or $ 130. So far, since the beginning of the attacks, the global oil has risen more than 20%”Says João Alfredo Nyegray, professor of international and geopolitical business at (Pontifical Catholic University of Paraná).
Coelho said that if the oil barrel exceeds $ 100, there will be a great risk to the global economy. An extreme effect is a supply crisis in Asia.
“We would have a great impact on Europe and especially in Asia. The main country to feel this would be China. China today matters much of the oil explored by Iran ”says Alexandre Coelho, Professor of International Relations at (São Paulo School of Sociology and Politics Foundation).
For the expert, Russia can benefit from the lock of the Ormuz Strait. The country could increase oil exports at a higher price, including for European Union nations if they are impacted by blockades in the region.
