Icelanders will decide Saturday whether the country should resume talks to join the European Union, a vote that critics say could split the nation over its prized fishing waters.

The fish and marine industries account for almost 40% of Iceland’s exports, and support for the EU is driven by promises of a steadier currency, lower inflation and tighter security cooperation. Opponents fear a loss of sovereignty when the EU’s Common Fisheries Policy imposes quotas that threaten the lucrative cod and haddock harvests.1

The referendum has become a flashpoint for wider geopolitical concerns. Russia’s navy has increased activity near Iceland’s exclusive economic zone, and the United States has shown interest in Greenland, which heightens Iceland’s sense that EU membership could provide a more robust defence framework as part of NATO.

Economically, Iceland remains one of the most expensive countries in Europe. Prices are 84% higher than the EU average, and interest rates sit at around 8%. The high cost of living is a primary concern for many voters, with newer generations especially feeling the burden of mortgage rates and housing affordability.2

If the Yes vote prevails, officials say negotiations with Brussels could begin within months, as Iceland already completed 11 of the 35 chapters of accession talks before its 2013 withdrawal. A No vote would postpone any future negotiations, keeping Iceland outside EU fold but possibly weakening its strategic influence in the region.

The outcome will have ripple effects across Europe, with neighboring Norway and the broader European Economic Area eyeing the decision closely as they evaluate their own positions on EU membership and maritime policy.

The referendum underscores how environmental, economic, and security arguments intersect in the Arctic, where sustainable fisheries, climate resilience, and sovereign control are increasingly intertwined.
