US intelligence agencies have recently assessed that Iran can effectively shut down access to the Strait of Hormuz at will from now on, meaning the country’s regime has acquired a powerful new ability to hurt the global economy as a result of the war, according to three sources familiar with the findings.

Hegseth said the U.S. naval blockage in Iran is "impenetrable" and 125 million barrels of oil have now exited the Gulf, "showing that we control the strait."

Iran has left open the possibility it could toll ships passing through the strait.
