The Trump administration has allowed Iran to sell oil again as part of a deal to stop fighting. Reuters reported this on June 18, 2026. This is a big change. Just a few months ago, the same administration was trying to stop Iran from selling any oil at all.

Here is why it matters: when countries cannot sell their oil, they lose money. Money is what Iran uses to pay for weapons and fund armed groups active in the Middle East. By blocking oil sales, the U.S. was trying to weaken Iran.

Early this year, the Trump administration made this policy official. In February 2025, it issued an order saying Iran was responsible for Hamas's attacks in October 2023 and for Houthi operations in the Red Sea. The order said Iranian oil money paid for these activities. The U.S. goal was simple: stop Iran from exporting any oil. As recently as May 2026, the U.S. was still punishing ships that carried Iranian oil, according to Reuters.

Then things started to shift. In March 2026, the Treasury Secretary said the U.S. might let Iran sell oil that was already sitting on ships at sea. Reuters reported this on March 19. This was a small opening—it let Iran make money from oil that already existed without officially saying the U.S. approved new oil sales.

Now that opening has gotten bigger. The June report suggests the U.S. is allowing Iran to sell not just old oil on ships, but newly produced oil too. This is real money: it is the main way Iran finances its military and armed groups.

What Else Is Changing

At the same time, the U.S. did something different with Russia. The U.S. Treasury let its permission for Russian oil sales expire on June 18, 2026 without announcing it or extending it. So Iran's restrictions are getting looser while Russia's are getting tighter.

This means different things for different oil buyers. Companies buying Russian oil now face legal trouble because they no longer have the U.S. government's protection. Companies buying Iranian oil may now be safer, at least for a while. Most of these buyers are in Asia, and they need to figure out their new strategy.

What Comes Next

The Trump administration declared a national emergency about Iran in February. This order is still in effect. Think of it as the legal foundation that lets the U.S. punish Iran. Because it is still active, the U.S. can quickly bring back strict sanctions if the talks fall apart. It does not need Congress to pass a new law or spend months writing new rules.

Sanctions deals like this one are temporary. From 2013 to 2015, countries worked on the Iran nuclear deal and changed the rules many times before reaching a final agreement. What seemed agreed in one version did not always stick in the next one. The Trump administration is probably offering this oil deal for two reasons: to give Iran some money so it keeps talking, and because the administration prefers a deal over endless tension.

The biggest question is what the deal actually says. What exactly can Iran sell? Which companies and ships are allowed? Will foreign companies be protected from U.S. punishment? These details have not been made public yet, but they will decide whether Iran actually sells more oil or whether this is mostly for show.
