Growing Iran Oil Exports Challenge U.S. Nuclear Sanctions

Iran’s oil exports have risen this year, according to Bloomberg calculations, a trend that threatens to violate U.S. sanctions on the Islamic Republic’s main source of revenue.

Shipments of Iranian crude oil and condensate have increased about 28 percent on average this year, according to an analysis of customs data from importing nations and figures from the International Energy Agency in Paris. If crude sales are up by the end of July, that would break an international accord to hold Iran’s oil exports at the same level in the first half of this year that they were at in the previous six months.
