The U.S. Secretary of State warns Iran not to close the Strait of Hormuz. In response to Iran's threat to close the "lifeline of oil" Strait of Hormuz, U.S. Secretary of State Rubio stated: "If Iran blocks the Strait of Hormuz, it would be another terrible mistake, and if they do so, it would be tantamount to economic suicide for them. The U.S. will keep all options on the table to address this issue."

If Iran blocks the Strait of Hormuz, the consequences would be unimaginable, affecting 20% of global oil transportation, causing oil prices to soar, leading to economic recession, and potentially triggering regional military conflicts or even all-out war.
The Strait of Hormuz is located between Iran and Oman. Although narrow, it sees 20% of the world's oil passing through daily, making it a vital artery for global fuel. Historically, it has never been completely blocked, with only partial blockages or threats of blockage occurring during the Iran-Iraq War.
From 1984 to 1988, Iran and Iraq engaged in the "Tanker War" near the Strait of Hormuz, where both sides attacked each other's tankers and laid mines, resulting in damage to multiple tankers and severe disruption to shipping. Although this operation did not completely block the strait, it increased the risks and costs of oil passage.
Since the 21st century, Iran has repeatedly threatened to block the Strait of Hormuz, such as during the peak of the Iran nuclear crisis in 2008, the expansion of U.S. and European oil sanctions in 2011, and the U.S. withdrawal from the Iran nuclear deal in 2017. However, these threats have not translated into actual blocking actions.
If Iran really does fully block the Strait of Hormuz this time, I'm afraid our oil prices will rise again!
