US Treasury Secretary Bessent to Press G20 Ministers on Curbing Iran’s Financial Networks

US Treasury Secretary Scott Bessent is expected to use the upcoming G20 finance ministers meeting to press international counterparts on intensifying efforts to disrupt Iran’s funding channels, according to reports confirmed by multiple diplomatic sources.

Why is Iran’s funding on the G20 agenda?

The move signals a strategic shift by the Trump administration to elevate financial pressure on Tehran within multilateral forums, rather than relying solely on unilateral sanctions. The push comes amid heightened concerns over Iran’s regional activities and its support for proxy groups, which the US and its allies argue are financed through complex networks of shell companies, cryptocurrency transfers, and trade-based money laundering.

By placing the issue on the G20 agenda, the US aims to build a broader international consensus, particularly among European and Asian nations that have been reluctant to enforce secondary sanctions. A senior Treasury official, speaking on condition of anonymity, stated that the objective is to “close the gaps” that allow Iranian entities to access the global financial system, emphasizing the need for collective action.

What specific measures is the US advocating for?

While the exact proposals have not been publicly detailed, diplomatic sources indicate that the US will push for enhanced due diligence requirements for correspondent banking relationships and stricter monitoring of trade finance transactions involving high-risk jurisdictions. The Treasury is also expected to advocate for greater information-sharing between financial intelligence units to trace assets linked to the Islamic Revolutionary Guard Corps (IRGC) and its commercial affiliates.

This initiative follows a series of recent US sanctions designations targeting Iranian oil brokers and shipping companies. As of early 2025, the US Treasury has designated over 30 entities and vessels for their role in transporting Iranian petroleum, a key revenue source for the government in Tehran. The G20 push is seen as an attempt to amplify these efforts by encouraging partner nations to adopt similar enforcement mechanisms.

Potential impact on global markets and diplomacy

The US initiative could create friction within the G20, as several member states, including China and India, maintain significant energy trade relationships with Iran. Analysts suggest that while a unified statement on Iran may be difficult to achieve, the diplomatic pressure alone could increase compliance costs for financial institutions operating in the region.

For global markets, the news adds a layer of geopolitical risk, potentially affecting oil price volatility. Traders are closely watching the meeting’s outcome for signals on whether stricter enforcement could remove more barrels from the market. However, experts caution that the impact will likely be gradual, as the implementation of such measures would require legislative and regulatory changes in multiple jurisdictions.

Conclusion

Secretary Bessent’s planned intervention at the G20 represents a deliberate effort to internationalize the campaign against Iran’s financial infrastructure. The success of this initiative will depend on the willingness of other major economies to align with US policy, a process that is likely to be contentious. For now, the move underscores the administration’s commitment to using all available diplomatic and financial tools to pressure Tehran.
