US Threatens Toughest Sanctions Yet as Iran Condemns Economic Warfare
The United States says it will impose very strong economic penalties on Iran.
These penalties could target Iran’s oil sales, money transfers and companies that help it.
US officials say the goal is to weaken Iran’s influence and stop it from rebuilding nuclear capabilities.
They also warned other countries not to keep supporting Tehran.
China was specifically urged to cooperate and help reopen the Strait of Hormuz.
The strait is an important route for energy shipments.
US officials say the waterway is open and that a naval blockade has worked.
An Iranian official says Iran will not reopen it until the United States meets several demands.
Iran says the sanctions are unfair and could harm the global economy.
More details about the US measures are expected at a Monday media conference.
Treasury Secretary Scott Bessent warned Iran of the “toughest sanctions in history” and said Washington seeks coordinated economic isolation.
President Donald Trump said the campaign would target Iran’s oil smuggling, financial transfers, exchange houses, ship registries and front companies.
The United States warned countries and institutions supporting Tehran of potentially severe economic consequences and urged China to cooperate.
Vice President JD Vance called economic pressure Washington’s most effective tool but acknowledged that higher oil prices could affect Americans.
Iran condemned the measures as “economic terrorism,” while US and Iranian officials disputed whether the Strait of Hormuz is open.

United States Position
Iranian Position
Purpose of sanctions
United States Position
Washington says economic isolation will weaken Iran’s ability to project influence, limit proxy activity and prevent it from obtaining or rebuilding nuclear capabilities.
Iranian Position
Tehran says the sanctions target the fundamental rights of Iranian citizens, amount to economic terrorism and will not weaken its resolve to defend its independence and interests.
Economic effects
United States Position
US officials argue that Iran is experiencing greater pressure and that sanctions can influence its negotiating position, while acknowledging that elevated oil prices affect Americans.
Iranian Position
Iranian officials say the policy reflects hostility toward the Iranian people, threatens the global economy and diverts attention from economic problems in the United States.
Strait of Hormuz
United States Position
Donald Trump says the Strait of Hormuz is open and that the US naval blockade has been extremely effective.
Iranian Position
Mohammad Bagher Ghalibaf says Iran will not reopen the strait until the United States lifts the blockade, releases frozen Iranian assets and eases oil sanctions under a 14-point memorandum.
- US policy
- The administration describes the campaign as the “most crushing economic operation” against a country and says it seeks to “collapse this regime.”
- Sanctions targets
- Trump named oil smuggling networks, swap lines, cash transfers, exchange houses, ship registries and front companies.
- Potential consequences
- Countries, financial institutions, businesses, airports and government entities supporting Tehran could face US economic action.
- China
- Bessent urged China to “get with the programme,” citing its reliance on energy from inside the Gulf.
- Military action
- Bessent said maximum economic pressure would likely mean a renewed military operation was less likely.
- Iranian response
- Iran’s Foreign Ministry called the sanctions “economic terrorism” and “crimes against humanity.”
- Strait of Hormuz
- Trump said the strait is open and the US naval blockade has been effective; Mohammad Bagher Ghalibaf said Iran would not reopen it until US commitments were fulfilled.
