LONDON — Iran’s crude exports fell further in the first week of October, according to tanker data and an industry source, taking a major hit from US sanctions.

Iran exported 1.1 million barrels per day (bpd) of crude in that seven-day period, Refinitiv Eikon data showed. An industry source who also tracks exports said October shipments were so far below 1 million bpd.

That’s down from at least 2.5 million bpd in April, before President Donald Trump in May withdrew the United States from a 2015 nuclear deal with Iran and reimposed sanctions. The figure also marks a further fall from 1.6 million bpd in September.

Tanker schedules are often adjusted and exports can vary week by week. The early October figures add to signs, however, that Iranian exports are falling more steeply than expected.

“The US government’s tough stance raised the stakes for a more significant Iran export loss than previously foreseen,” said Norbert Ruecker, head of macro and commodity research at Swiss bank Julius Baer.

None of the Iranian crude exported in the first week of October is heading for Europe, according to the Refinitiv data.

The Trump administration is considering waivers on sanctions for countries that are reducing their imports.

India, a major buyer, has ordered Iranian oil for November, although New Delhi does not yet know whether it will receive such a waiver. — Reuters
