President Donald Trump on Friday vowed to hit Iran hard economically, a day after Treasury Secretary Scott Bessent said Washington would impose measures on Tehran that have never been seen as soon as next week. The administration's remaining options include secondary sanctions on Chinese independent teapot refiners, which buy most of Iran's shipped oil, and on two larger Chinese banks that officials have not publicly identified.
Key Facts
- President Donald Trump on Friday vowed to hit Iran hard economically, and Treasury Secretary Scott Bessent said Washington would impose measures on Tehran that have never been seen as soon as next week.
- OFAC has imposed sanctions on more than 1,000 people, vessels and aircraft since Trump began his second term.
- Recent measures have frozen an estimated $500 billion in Iran-linked cryptocurrency.
- Chinese independent refineries known as teapots account for a quarter of Chinese refinery capacity, and China buys more than 80% of Iran's shipped oil.
- Treasury has warned two larger Chinese banks that secondary sanctions would follow if Iranian funds moved through their systems, but has stopped short of designating them.
Chinese Teapot Refiners
Chinese independent refineries known as teapots account for a quarter of Chinese refinery capacity and operate with narrow and sometimes negative profit margins. China buys more than 80% of Iran's shipped oil, according to 2025 data from analytics firm Kpler, and independent refiners absorb much of this trade. That exposure makes the independents targets for so-called secondary measures that penalize entities helping a primary sanctions target. Past U.S. sanctions have deterred larger independent refiners from buying Iranian oil, but the smaller independent refineries have little exposure to the U.S. financial system and are difficult to reach through secondary measures.
Chinese Banks and Secondary Sanctions
OFAC has imposed secondary sanctions on smaller China- and Hong Kong-based entities accused of processing billions of dollars in Iranian oil and helping to fund weapons procurement. Treasury has warned two larger Chinese banks that secondary sanctions would follow if Iranian funds moved through their systems; it has stopped short of designating them. The two banks have not been publicly identified by U.S. officials. Trump administration officials have sought to play down tensions between Washington and Beijing ahead of an expected meeting between Trump and President Xi Jinping later this year.
Shadow Fleet, Weapons and Crypto
Since the Iran war began in February, Washington has levied additional maritime, energy and financial sanctions and started a naval blockade. Recent measures have targeted Iran's shadow oil fleet, shipping insurers, entities and people enabling Iran's acquisition of weapons, and digital exchanges. These measures have frozen an estimated $500 billion in Iran-linked cryptocurrency. OFAC data show the agency has imposed sanctions on more than 1,000 people, vessels and aircraft since Trump began his second term.
