Iceland votes on restarting EU membership talks amid Arctic security fears

Iceland goes to the polls on Saturday in a referendum that could reshape the country's place in Europe and the North Atlantic. The question is deceptively simple: should the government reopen accession negotiations with the European Union, thirteen years after a Eurosceptic administration pulled the plug on the previous round? Yet the forces driving the vote, a volatile currency, the highest consumer prices in Europe, and a rapidly militarising Arctic, are anything but simple.

A history of hesitation

Iceland applied for EU membership in July 2009, weeks after the financial crisis exposed the fragility of its oversized banking sector. Negotiations opened the following year and progressed through 27 of 35 policy chapters before the centre-right coalition of Sigmundur Davíð Gunnlaugsson halted them in 2013, arguing the island would thrive outside the bloc. The decision was never put to a public vote. Parliament simply voted to "pause" the process, a phrasing that left the application technically alive but politically dormant.

Since then, Iceland has remained inside the European Economic Area and the Schengen area, giving it access to the single market and passport-free travel without a seat at the table where the rules are written. That arrangement has served the country well in many respects. But the economic and strategic landscape has shifted enough to bring the question back to the electorate.

The economic case: currency and cost of living

The most immediate pressure is domestic. Consumer prices in Iceland exceeded those of every EU member state in 2025, standing 87 percent above the bloc's average. The krona, a currency of just 395,000 users, has swung wildly against the euro and the dollar, raising borrowing costs and deterring long-term investment. Earlier this year the Ministry of Finance and Economic Affairs published a report concluding that the costs of maintaining an independent currency probably outweigh the benefits, and that adopting the euro could reduce both interest rates and transaction costs.

EU membership would bring Iceland into the customs union, eliminating tariffs on goods from member states and applying a common external tariff. It would also open the path to euro adoption, though that would require a separate convergence process. Adam Fishwick, who teaches international relations at the University of Iceland, notes that membership could also unlock dedicated EU regional development funds, a non-trivial consideration for a country where population and economic activity are heavily concentrated in the capital region.

The economic argument is not one-sided. Opponents point out that Iceland already enjoys most single-market benefits through the EEA agreement without contributing to the EU budget or accepting the common fisheries policy. They also warn that the transition costs of alignment, legal, regulatory, administrative, are routinely underestimated by accession aspirants.

Fishing: the industry that defines the debate

No sector looms larger in the Icelandic imagination than fishing. In 2024 it contributed roughly 8 percent of GDP directly and a far larger share indirectly through processing, services and coastal employment. The industry's quota system, built on individual transferable quotas, is regarded internationally as a model of sustainable management. The fear is that the EU's common fisheries policy would impose foreign vessels in Icelandic waters, redistribute quotas, and subordinate Reykjavik's decisions to Brussels.

Valur Ingimundarson, professor of contemporary history at the University of Iceland, put it bluntly: "The fundamental objection to EU membership is that Iceland would not retain full control over its fisheries, the traditional backbone of the economy." He argues that even a "yes" vote on Saturday would not lead to membership unless Iceland secures "ironclad" exemptions, a demand that would test the EU's willingness to accommodate a new member on a policy area where it has historically insisted on uniformity.

Arctic security and the American question

If economics provides the domestic fuel for the referendum, geopolitics supplies the strategic spark. Iceland is a founding member of NATO and hosts a US base at Keflavík under a bilateral defence agreement dating to 1951. It has no standing armed forces of its own. That arrangement worked comfortably for decades. It works less comfortably now.

Russia has expanded its military footprint in the High North, reactivating Soviet-era bases and testing NATO's northern flank with increased submarine and bomber activity. At the same time, President Donald Trump has repeatedly threatened to use force to acquire Greenland, an autonomous territory of Denmark lying just 300 kilometres west of Iceland. The combination has left Reykjavik feeling exposed.

Gabriella Gricius of the Norwegian Military Academy explains the logic: "As the US has grown more unpredictable, and specifically, its rhetoric around Greenland has grown more concerning, it is not surprising that Iceland is seeking additional security guarantees through the EU." Thorgerdur Gunnarsdottir, the foreign minister, told Reuters that Iceland has been "disappointed" with the US "pressure campaign waged against both Greenlanders and Denmark," while also identifying Russia as a threat "in our waters and nearby, in the North Atlantic." She stressed that NATO and the US would remain Iceland's core security partners, but described EU membership as "a valuable addition."

What the polls actually show

Public opinion has been remarkably volatile. A Gallup poll conducted this week found 51.6 percent opposed to restarting talks and 48.4 percent in favour. Days earlier, the Icelandic pollster Maskina recorded a narrow majority, 51.3 percent, backing negotiations. The discrepancy likely reflects sampling differences and the high proportion of undecided voters typical of constitutional questions. What is clear is that neither side commands a comfortable lead.

Prime Minister Kristrun Frostadottir, whose Social Democrats campaigned on a pro-European platform, has said she will honour whatever the public decides. A "yes" vote would see the nation "enter negotiations with our heads held high and stand together in seeking a good agreement," she said. A "no" would mean "all speculation about what [EU membership] might involve will be set aside."

The EU's calculation

For Brussels, Iceland is an unusual candidate. It is wealthy, institutionally advanced, and already aligned with most of the acquis through the EEA. Accession would be technically straightforward in most policy areas. The fisheries chapter would be the exception, and the political price of an exemption could be high, setting a precedent for other coastal states or future candidates.

There is also a strategic dimension. Gricius notes that Icelandic membership would make the EU a four-state Arctic actor alongside Finland, Sweden and Denmark. "It may influence how the EU behaves in the Arctic, as the EU would then include four of the eight Arctic states," she said. The bloc's new Arctic strategy, updated in 2024, emphasises climate security, sustainable development and strategic autonomy, all areas where Iceland's geography and expertise are relevant.

The road from referendum to membership

A "yes" on Saturday would not make Iceland an EU member. It would merely authorise the government to request the reopening of negotiations. The European Council would need to agree a negotiating mandate. The 35 chapters, eight already closed, 27 at various stages, would be revisited. New chapters on justice, fundamental rights and financial services have been added to the framework since 2013. Any resulting treaty would require ratification by all 27 member states and, crucially, a second Icelandic referendum.

The timeline is measured in years. The previous round took four years to reach the pausing point. Accession treaties for recent entrants have taken between six and ten years from application to entry into force. Iceland's EEA alignment shortens the technical work, but the political negotiations, especially on fisheries, could be protracted.
