Top 5 Geopolitical Disruptions – Q1 2025

Q1 2025 featured the highest number of sanctioned vessels since 2022 and the largest number of both new and alignment designations of maritime companies by global regulators since early 2023.

There was also a major change in how vessels experiencing GPS jamming started appearing on tracking maps and three new GPS jamming hotspots emerged.

This report delves into the volatile landscape of geopolitical tensions and sanctions regimes, offering Maritime AI-generated insights so you can better understand and quantify the scope of disruption and new trends…
