US Treasury chief signals weekly Iran sanctions push at G20

Scott Bessent, the US Treasury Secretary, has signalled an aggressive approach to Iran sanctions, indicating that new measures targeting secondary transactions will be rolled out on a regular weekly schedule. The strategy aims to systematically increase economic pressure on Iran through coordinated international action.

Bessent plans to use his engagement with G20 finance ministers and central bank governors to deliver a stark message: countries and entities must choose between maintaining economic relationships with Iran or facing secondary sanctions imposed by the United States. This approach seeks to isolate Iran's financial system from the broader global economy.

The announcement reflects a hardline stance on Iran policy, with the Treasury Department preparing a sustained campaign rather than a one-time action. The weekly sanctions cadence suggests a methodical effort to close loopholes and target new segments of Iran's international economic activities over time.

Secondary sanctions are penalties imposed on third parties—individuals, companies or nations—that conduct business with targeted entities or countries. By threatening secondary sanctions, the US aims to discourage global financial institutions and commercial partners from engaging with Iran, effectively expanding the reach of its Iran policy beyond direct bilateral restrictions.
