At least three Indian oil-refining companies and one global energy firm are avoiding tankers listed on a new Iranian blacklist [1], [2].

This shift in logistics highlights the precarious nature of energy transit through the Strait of Hormuz. Companies are weighing the cost of alternative shipping against the risk of Iranian interference with their cargo.

According to a report from Reuters on Aug. 26 [1], the companies plan to stop using vessels that Iran has flagged in its recent blacklist. The move comes as Iran maintains strict control over the narrow waterway, where security tensions frequently disrupt global oil flows.

Industry sources said the decision is driven by security concerns. Companies fear that tankers on the blacklist could face heavy fines, detention, or seizure by Iranian authorities [1], [2]. These risks create significant financial and operational liabilities for the firms managing the shipments.

In total, four companies have already taken steps to distance themselves from the flagged vessels [2]. This includes the three Indian refineries and one major global energy entity. The companies are now seeking alternative transport to ensure their oil supplies are not intercepted in Iranian-controlled waters.

While the specific names of the firms were not provided, the trend suggests a broader effort by Asian energy markets to mitigate geopolitical risks. The Strait of Hormuz remains a critical chokepoint for global energy, and any increase in Iranian enforcement of blacklists can lead to immediate shifts in shipping routes.

The avoidance of blacklisted tankers indicates that private energy firms are prioritizing risk mitigation over shipping efficiency in the Strait of Hormuz. By preemptively steering clear of Iranian-flagged vessels, these companies are attempting to avoid the legal and financial fallout of vessel seizures, which Iran has used as a geopolitical tool. This suggests a growing trend of 'de-risking' in the energy sector to bypass Iranian regulatory or military pressure.
