Treasury directs banks to steer clear of China’s ‘teapot’ refineries

semafor.com·Apr 28, 2026

The U.S. Treasury Department has instructed banks to avoid transactions with China's "teapot" refineries, which are involved in importing Iranian oil, as part of a broader strategy to increase economic pressure on Iran amidst ongoing tensions. This guidance includes conducting enhanced due diligence and communicating sanctions risks to Chinese banks to prevent facilitation of transactions with Iran.

The U.S. Treasury's directive urging banks to distance themselves from China's 'teapot' refineries signifies an intensified economic strategy against Iran and its oil exports, leveraging financial institutions to enforce compliance. For professionals tracking global economic sanctions and trade, this move underlines the growing geopolitical strategy of economic pressure as a tool in foreign policy, potentially impacting supply chains and financial transactions involving Chinese and Iranian entities. This could be a pivotal point for assessing risks and opportunities in sectors tied to oil trade and financial services with these regions.
