Iran has warned of potential actions to close the Strait of Hormuz in response to U.S. strikes on its nuclear facilities, specifically those conducted in coordination with Israel. The Strait is a crucial shipping route, with approximately 20% of global oil and petroleum products transiting through it. The Iranian parliament has discussed this plan, but any decision would need to be approved by the Supreme National Security Council.
The Strait of Hormuz, which connects the Persian Gulf to the Gulf of Oman, is only about 30 miles wide at its narrowest point, making navigation challenging should Iran attempt to obstruct shipping. In 2024, oil flows through the strait averaged around 20 million barrels per day, and it accounted for more than a quarter of total global seaborne oil trade. Additionally, around 20% of global liquefied natural gas trade also passed through this vital corridor.
Countries that rely heavily on oil imports from the region, particularly China, which imports around 5.4 million barrels per day, would be significantly impacted by any disruptions. U.S. Secretary of State Marco Rubio has urged countries such as China to discourage Iran from pursuing this course of action, emphasizing that such a move would harm Iran’s own economy.
The potential closure of the Strait of Hormuz raises concerns about global energy supply and could lead to increased oil prices. Rubio indicated that while the U.S. remains open to negotiation, it also has options available if Iran decides to escalate tensions further. The situation remains fluid, with the international community closely monitoring developments.
