Unilateral US sanctions on Iran are unlikely to have a major impact on the global crude supply and demand balance, say analysts.

“While the US imports no oil from Iran directly, companies with key US assets or headquarters could be affected by unilateral sanctions,” says Cowen & Co analyst Sam Margolin.

“However, the volume of Iranian crude exports to major integrated oil companies (IOCs) is relatively small, and it is likely that renewed US sanctions have a much smaller impact on oil supply than the pre-nuclear deal sanctions.
