Iran hasn't successfully exported any crude oil by sea over the past 28 days, via Tanker Trackers

To our best knowledge, Iran hasn't successfully exported* any crude oil by sea over the past 28 days.  Some refined products managed to escape because US OFAC did not slap sanctions on those tankers.    In addition, Kharg Island hasn't loaded any tankers since 2026-05-06 as a result of the oil leak which Tehran denied taking place.     That said, there are still plenty of cargo-empty tankers both inside and outside the blockade perimeter; as well as plenty of cargo-laden tankers grouped together not too far away from Pakistan.     *(Our updated definition of an export out of Iran is when a tanker exfiltrates the US Navy blockade line and doesn't return with the oil.)
