The Trump administration has launched a new, aggressive financial campaign against Iran, threatening an "economic D-Day" and "Operation Economic Fury." This initiative involves coordinated sanctions against Iran's financial flows and a naval blockade of its ports. Treasury Secretary Scott Bessent indicated that secondary sanctions will be imposed on nations and companies conducting business with Iran, with details to be announced. This move comes as the Iran war nears its six-month mark and aims to pressure Tehran, which has a long history of enduring and adapting to American sanctions over nearly five decades.
Iran, however, has vowed a "devastating" response to these new threats, with Foreign Minister Abbas Araghchi noting that Iran has "seen this movie before." Analysts are divided, with some Iran hawks praising the strategy and calling for patience, while others warn that the Trump administration may be repeating past mistakes. The effectiveness of these sanctions will largely depend on how other countries, including US allies like Turkey and Iraq, as well as China, react, as Iran has shown an ability to use irregular channels and "shadow" vessels to bypass previous sanctions.
Despite the US blockade on Iranian ports, reimposed on July 13, and a significant reduction in shipping traffic through the Strait of Hormuz, Iran continues to possess leverage over the waterway. Only two to three Very Large Crude Carriers (VLCCs) have transited the strait daily since July 7, compared to roughly eight before the war, according to Kpler data. While oil prices have seen some fluctuations due to the sanctions threat, Bessent suggested that maximum economic pressure might preclude large-scale military action. China, which purchased over 80% of Iran’s shipped oil in 2025, is a key target of these secondary sanctions, but this risks economic retaliation against Washington.
Michael Parker, an expert on economic sanctions, highlights that the new strategy aims to "expand the economic blast radius" by targeting third countries whose economies depend on the US dollar. He notes that Iran's ability to evade sanctions is contingent on other countries' willingness to provide access to the formal banking system. While sanctions can be a powerful tool, their long-term impact on Iran's behavior remains uncertain without a broader strategic context.
Recent developments suggest Iran's regional ambitions have been scaled back due to the dismantling of its regional network, as noted by Aviva Klompas in USA Today. This outcome is considered a significant, albeit underappreciated, consequence of the ongoing conflict.
