Tankers defy sharp escalation of Iranian attacks to keep crude oil flowing through Strait of Hormuz

By · Published by Everything Blog

In short

To maintain vital maritime traffic, operators have implemented a shuttle system that offloads crude to waiting carriers in the Gulf of Oman, helping total flows rise more than 70% since July. Despite these adjustments, daily passage remains highly volatile and fell to 7.3 million barrels per day during late October. Meanwhile, regional producers have started absorbing soaring freight charges and utilizing their own fleets to prevent Asian refiners from defecting to American crude suppliers.

Iran's campaign was initially successful, with crude exports plunging nearly 90% to 1.8 million barrels a day in March compared with 16 million bpd in February, according to data provided by Kpler.

But crude flows have rebounded over the past eight months as the U.S. military provides protection to tankers transiting Hormuz. Tehran has responded by escalating its attacks in recent weeks.

More commercial ships have come under attack in October than at any other point in the war. Yet in contrast to March when exports cratered, tankers have continued to ferry substantial volumes of crude oil through Hormuz in a sign that the shipping industry has adapted to wartime in the Persian Gulf.

As of Oct. 27, at least 30 vessels, mostly oil tankers, were hit this month leaving at minimum 16 seafarers injured, according to data from the…
