The U.S. Treasury Department is preparing to announce new sanctions that broaden the scope of secondary sanctions on entities doing business with Iran [1, 2].

These measures aim to isolate the Iranian economy further by penalizing third-party actors. By targeting foreign companies and countries that maintain trade ties with Tehran, the U.S. government seeks to limit Iran's ability to fund its regional activities and nuclear program [1, 2].

The Treasury is expected to announce the expanded sanctions on Monday, Aug. 26, 2024 [1]. This move follows reports that the administration wants to heighten economic pressure on Tehran amid ongoing concerns regarding its nuclear capabilities [1, 2].

Secondary sanctions differ from primary sanctions by targeting non-U.S. persons and companies. While primary sanctions prohibit U.S. citizens and firms from trading with Iran, secondary sanctions threaten to cut off foreign entities from the U.S. financial system if they continue to engage in significant trade with the targeted nation [1, 2].

The broadened scope would likely encompass a wider range of sectors and a larger number of foreign entities [1]. This strategy is designed to force international businesses to choose between trading with Iran or maintaining access to the U.S. market, a trade-off that typically favors the larger U.S. economy [1, 2].

U.S. officials said these steps are necessary to curb Tehran's influence in the region [1, 2]. The timing of the announcement suggests a push to strengthen the U.S. bargaining position before potential diplomatic engagements regarding Iran's nuclear program [1].

The expansion of secondary sanctions represents a shift toward a more aggressive 'maximum pressure' economic strategy. By targeting third-party intermediaries, the U.S. is attempting to create a global financial perimeter around Iran, effectively outsourcing the enforcement of U.S. foreign policy to international banks and corporations that fear losing access to the U.S. dollar.
