Sweden Strengthens Surveillance Against Russian Shadow Fleet in the Baltic Sea

Sweden tightens controls and surveillance against the Russian shadow fleet in the Baltic Sea starting July 2025.

Key Points

  • • Sweden increases controls over foreign vessels starting July 1, 2025.
  • • New measures allow collection of insurance information from ships in Swedish waters.
  • • Justice Minister emphasizes deterrent effect against Russian shadow fleet.
  • • Related concerns include recent sabotage incidents and heightened military presence in the Baltic.

On May 31, 2025, the Swedish government announced new measures to enhance surveillance and control over foreign vessels, targeting the Russian "shadow fleet" operating in the Baltic Sea. Effective from July 1, 2025, the Coast Guard and Maritime Administration will now be allowed to collect insurance information from ships traversing Swedish territorial waters and economic zones. Previously, these checks only applied to vessels docking at ports.

Justice Minister Gunnar Strömmer stated that the initiative aims to deter vessels associated with the Russian shadow fleet, which often operates without proper insurance. Strömmer described the decision as a significant move to showcase Sweden’s commitment to maritime security amidst rising regional tensions. "This decision serves as a crucial deterrent against the vessels linked to Russia's shadow fleet and underscores our resolve in ensuring safety in our waters," he remarked.

The shadow fleet, utilized by Russia to transport oil to trading partners while circumventing sanctions, presents significant concerns for Sweden and its neighboring countries. Earlier warnings from former Foreign Minister Tobias Billström also underscored the potential dangers posed by these vessels, which often sail under false flags and may be poorly maintained.

In addition to the new regulations, tensions in the region have been highlighted by other recent developments, including the investigation into three individuals suspected of having sabotaged the oil tanker Eagle S, which reportedly damaged several underwater cables in the Baltic Sea in late 2024. Finland has also expressed concerns over increased Russian military presence and recently summoned the Russian ambassador to demand clarification regarding an airspace violation.

Overall, Sweden's tightened regulations are part of a broader strategy to enhance national security and response to unauthorized activities in the Baltic Sea, reflecting an increase in geopolitical friction in the area. The government aims for these measures to facilitate the identification and sanctioning of vessels that operate outside legal norms, thereby enhancing regional stability.
