Treasury Secretary Scott Bessent has a new plan to pressure Iran, and it involves going after the countries that still do business with Tehran.
The campaign, which Bessent described as an "economic D-Day" effort, is designed to cut Iran off from the global financial system. Any country that keeps trading with Iran could face US penalties, according to the announcement.
Bessent said President Donald Trump has been calling foreign leaders with specific demands to stop dealing with Iran. Countries are being given a chance to fix their behavior before penalties hit, he added.
The Treasury Secretary framed the effort as a way to cut off Iran's financial connections around the world. He described it as "economic asphyxiation" of the Iranian regime, which is a vivid way of saying the goal is to choke off the money flowing in and out of the country.

This is not a brand new set of powers, though. Claire O'Neill McCleskey, who used to work at the Treasury, pointed out that the action appears to use authority the Treasury has had since 2020. That matters because it suggests the administration is reaching for tools already on the shelf rather than waiting for the legislative branch to grant new ones.
The announcement is part of a much larger push that has been building for months. US airstrikes have been hitting Iran since late February, and the conflict is now in its sixth month. On top of that, Iran has been under various economic sanctions for decades.
The war has been a political problem for Trump at home. With midterm elections coming in November, the administration is under pressure to show progress. A conflict that drags without a clear win is never good news for the party in power, and this one has been going on for nearly six months.
Bessent's message to the rest of the world is clear: stop doing business with Iran, or face consequences. The campaign is meant to put maximum pressure on Tehran's economy, hitting it from every angle at once.
The big question is whether this actually changes anything. Analysts are not entirely convinced that cutting off financial ties will be enough to make Iran back down, especially when it comes to the Strait of Hormuz. That narrow strip of water is one of the most important oil shipping lanes on the planet, and Iran has shown a willingness to threaten it.
For investors, this is a reminder that geopolitical risk does not stay in one place. When the US tightens sanctions on a major oil-producing country, energy markets tend to feel it. Companies that do business in the region, shipping firms, insurers, and anyone with exposure to Middle East supply chains could see ripple effects.
The other thing to watch is how other countries respond. If major trading partners push back or find ways around the sanctions, the campaign loses its teeth. If they fall in line, the pressure on Iran builds quickly.
Either way, this is not a one-week story. The effects of sanctions like these take months to show up in prices and in diplomatic behavior. For now, the message from the administration is clear: the squeeze on Iran is getting tighter, and the rest of the world has to pick a side.
