Lawmakers on both sides of the U.S. Congress are urging the Treasury Department to impose sanctions on Chinese banks that facilitate Iran's financial activities, aiming to cut off Tehran's economic lifeline. This push comes amid growing bipartisan frustration with China's role in enabling Iran's actions, particularly its chokehold on the Strait of Hormuz.
Treasury Secretary Scott Bessent has pledged to sanction Iran's "enablers" and stated that "no one is above the reach of U.S. sanctions." The Treasury Department recently expanded its authority to penalize foreign companies supporting five key sectors of Iran's economy: digital assets, technology, gold, aviation, and shipping. However, the initial round of sanctions focused on Hong Kong and China-based companies implicated in illicit Iranian oil transfers and assistance with Tehran's missile technology development program, rather than major Chinese financial institutions.
Going after Chinese banks presents a significant risk, potentially antagonizing Beijing and destabilizing the global finance sector, especially at a time when the U.S. is seeking to maintain a fragile trade truce. Despite these risks, some lawmakers argue that the U.S. may need to take such action to hold accountable any financial institution knowingly assisting the Iranian regime. Chinese state banks are known to serve as conduits for transactions where Iran sells oil to China's "teapot refineries," with funds often transferred through smaller provincial banks to large state-owned banks with Hong Kong subsidiaries.
Beijing has characterized the threat of sanctions as "economic warfare" and warned of potential retaliation. Chinese Foreign Ministry spokesperson Lin Jian stated that new U.S. sanctions would "fuel tensions and lead to risk spillover, which will disrupt the global economic and financial order." Lawmakers like Rep. Haley Stevens (D-Mich.) emphasize the need for a strategic approach that accounts for the risk of Chinese retaliation, particularly given Beijing's past actions of weaponizing its dominance in rare earths.
The administration is reportedly weighing the benefits of sanctioning Chinese banks against the potential negative impact on upcoming high-level diplomatic meetings. Sanctions on major Chinese state-owned banks, such as Bank of China, China Construction Bank, Industrial & Commercial Bank of China, and Agricultural Bank of China, which collectively hold an estimated $25 trillion in assets, could have significant ripple effects across international finance. Bessent has alluded to a strategy of giving potential targets time to "remedy bad behavior" before imposing sanctions, questioning the need to "blow up the global financial system."
