Iran just pulled off one of the most brazen energy market moves of the year. On July 9, Iranian oil tankers exported approximately 10 million barrels of crude and fuel in what appears to be a single overnight push, according to shipping data from TankerTrackers.com.
The timing is not subtle. Washington revoked Iran’s temporary oil sales waiver just two days earlier, on July 7, effectively tearing up a key provision of the fragile ceasefire agreement that had been holding together since June 2026. Tehran’s response was to flood tankers with as much crude as physically possible before any naval blockade could take shape.
A sanctions squeeze that’s been building for months
Iranian crude exports had already cratered to between 200,000 and 260,000 barrels per day in May 2026, a six-year low driven by stringent US sanctions imposed in April.
The result of those export restrictions: approximately 147 million barrels of Iranian oil sitting in floating storage as of May 2026. All of it parked on tankers with nowhere to go.
