What Actually Changed in the Trade After Fremantle Highway
By Vignesh D. · March 25, 2026 · 6 min read
The 2023 casualty was the inflection. Two years on, the changes you can attribute to it are not where the press coverage suggested they would be.
In the months after Fremantle Highway in 2023, the narrative was that the trade would respond with a wave of EV bans, public manifests, and new IMO action. Two years on, the actual changes are quieter, slower, and more commercial than the headlines predicted.
What changed
- Underwriter behaviour, not regulation, drove the early response.
- EV-percentage limits became an internal operator metric, never a public one.
- Classification societies issued guidance, not rules — leaving operators to interpret.
- IMO sub-committee work began but at the standard pace, not an emergency one.
What did not change
No new global rule on vehicle-deck detection has entered force. No carrier has publicly disclosed a route-level EV cap. The trade has continued to move EVs at increasing percentages without a regulatory floor for monitoring. The slack has been absorbed by insurers and operator-internal policy — both invisible from outside.
The lesson is that the system reacts through pricing and procurement, not through regulation, on a timescale measured in years. Anyone waiting for a rule is waiting in the wrong queue.
