On July 7, 2026, the U.S. Treasury's sanctions office, known as OFAC, wiped out a rule that had allowed companies to buy and sell Iranian oil. It replaced that rule with a new one the same day. OFAC

The rule that got canceled—called General License X—had been alive for only two weeks. Reuters It was supposed to last for 60 days. Nobody outside Treasury knew what the new rule would say or how different it would be.

Why does this matter to ordinary people? Sanctions rules control whether banks, oil traders, shipping companies, and insurers can do business with Iran. When those rules flip fast and without warning, it makes banks nervous. Nervous banks charge more for loans, or they avoid the business altogether. That can ripple through global oil prices and financial markets.

The real puzzle is the pattern. In March 2026, the U.S. announced it might let companies buy Iranian oil that was stuck on ships at sea. Reuters A day later, it issued a 30-day permit to do exactly that, saying it wanted to calm oil prices. Reuters Then, in mid-April, the U.S. let that permit expire without renewing it. Reuters Two months later came the 60-day License X. Then, two weeks after that, it was dead.

Think of it like this: imagine a store manager keeps changing which items customers can buy—opening it, closing it, opening again—without telling anyone the new rules until the moment they take effect. That's stressful for shopkeepers trying to plan their business.

At the same time, the U.S. has been cracking down hard on Iran's shadow fleet—a network of tankers that ferry Iranian oil around the world in ways that dodge official tracking. Treasury So the government is both tightening rules and loosening them, sometimes within weeks.

This pattern suggests the U.S. is using these rules as a lever in talks with Iran, turning them on and off to signal willingness to negotiate while keeping the option to reverse course fast if talks stall. That flexibility helps diplomats. But it makes life much harder for the banks, traders, insurers, and shipping companies that have to follow the rules—they can't build reliable procedures when the ground shifts beneath them every few weeks.

The new rule, License X1, has not been explained publicly. It may permit the same activities as License X, or it may be narrower or wider. Companies with Iranian oil exposure will need to read the full X1 text to know what's allowed.
