Q2 2025 Maritime GPS Jamming Disrupts 13,000 Vessels, Sparks Global Trade Impact

The second quarter of 2025 experienced intensified maritime disruptions largely due to geopolitical tensions, with a significant rise in vessel sanctions and widespread GPS jamming impacting over 13,000 vessels globally, especially in the Arabian Gulf amid the Iran-Israel conflict. This conflict triggered a surge in GPS jamming incidents, peaking on June 22 with over 1,700 affected vessels in a single day, complicating vessel screening and compliance efforts due to false port call signals near Iranian waters. These disruptions adversely affected crude oil exports and caused congestion at strategic ports like Singapore and Busan. The frequency and severity of such events highlight ongoing challenges in maritime safety and security in high-risk regions. Efforts to monitor and respond to these incidents are critical to maintaining operational integrity in global shipping lanes. These findings emphasize the need for enhanced maritime risk management as geopolitical tensions continue to influence ocean affairs.
