Oil tanker traffic through Hormuz at near standstill as attacks strain Iran truce
Context
By Jonathan Saul LONDON, July 9 (Reuters) - Oil tanker traffic through the Strait of Hormuz was at a near standstill on Thursday, according to data and sources, as shipping risks escalated after the U.S. renewed airstrikes on Iran, triggering retaliation by Tehran in the Gulf. Just two tankers had so far sailed through the strait in the early hours of Thursday. They included the crude supertanker Berg 1, which had loaded at Iran's Kharg Island and is subject to U.S. sanctions, according to analysis from Kpler.
What it means
A near-complete halt to tanker traffic through the Strait of Hormuz — driven by active U.S. airstrikes and Iranian retaliation — represents a genuine escalation beyond prior signals and has historically been associated with sharp crude oil spikes, pressure on airlines via fuel costs, and gains in defense stocks. While Brent and energy broadly have already been flagged in this ongoing situation, the move from 'threat' to 'operational standstill' is new information that markets have not yet fully priced. This is informational analysis, not investment advice.
