Iceland votes on restarting EU accession talks as Arctic security shifts

On Saturday, Iceland's 400,000 residents go to the polls for a referendum that could restart the country's long-dormant bid to join the European Union. The question is narrow: whether to unfreeze accession talks that have been on ice since 2013. But the context has shifted dramatically since Iceland first applied in 2009, in the wake of a financial crisis that wiped out household savings and brought the banking system to its knees. Back then the debate was almost purely economic. Today it is overlaid with Arctic security, great-power competition and a European Union eager to prove it can still grow.

A referendum on optionality

The centre-left coalition led by the Social Democratic Alliance campaigned on holding this vote no later than 2027. Prime Minister Kristrún Frostadóttir has framed a yes vote as a low-stakes step: "It's preserving optionality to see what an agreement looks like. You can be a 'maybe' person on the EU and still say 'yes' because you want to see what this looks like." If the referendum passes, a second national vote, likely more than a year away, would decide whether to accept any final accession deal. The foreign minister has said negotiations could take 18 months.

Polling from Gallup shows the outcome is genuinely uncertain. Among those with a position, 51.5% favour resuming talks and 48.5% oppose it, with a small undecided remainder. That margin is well within the margin of error. The result will turn on whether voters see the EU as a source of stability or a threat to the control of natural resources that has underpinned Iceland's prosperity.

The Arctic security backdrop

Since Donald Trump returned to the White House, his repeated demands for control over Greenland, and his occasional confusion of Greenland with Iceland, have concentrated minds in Reykjavík. "The brazenness of it caused angst in Iceland," said Ragnar Hjálmarsson, senior adviser at the Icelandic think tank Varda. "It also made Icelanders aware of the strategic importance of Iceland." The country has no army or defence ministry, only a coast guard, but it is a NATO member and hosts critical North Atlantic infrastructure. US forces left in 2006 as the perceived threat faded; they have returned since Russia's invasion of Ukraine, and NATO investment has followed.

In June, Iceland signed a maritime security pact with four other NATO allies to bolster surveillance in the Arctic and North Atlantic, a direct response to increased Russian naval activity. For the EU, this changes the accession calculus. "For the European Union, Iceland will be in the security environment a much more relevant partner compared to, say, 10 years ago," said Almut Möller, director for European and global affairs at the European Policy Centre in Brussels. "This is a very different context." The bloc also sees political value in welcoming a wealthy, stable democracy after the shock of Brexit. "There is an appetite within the 27-nation bloc to show the union is alive and ticking," Möller added.

Economic arguments: the krona versus the euro

Domestically, the debate still centres on the economy. Iceland ranks in the top ten globally for GDP per capita, at $98,300, slightly above the United States, and enjoys universal healthcare, preschool and equal paid family leave. Unemployment is low. But the 2008 crisis left deep scars, and the small national currency remains a source of volatility. The krona's swings fuel inflation spirals and make long-term planning difficult for businesses. Frostadóttir has argued that eurozone membership would bring investment, stability and an end to the cost of maintaining large currency reserves, which she says is "costing us a ton."

Proponents also point to concentrated domestic markets. Oil import and distribution is controlled by three or four companies, a pattern repeated across major sectors. EU membership would bring competition law enforcement and access to structural funds for Arctic agriculture, infrastructure and research. Opponents counter that Iceland's prosperity was built on sovereign control of its resources, particularly fish. The fishing industry accounts for 6.5% of GDP, according to Nordic Council data, and the memory of the Cod Wars with Britain in the 1970s remains potent.

Fishing sovereignty and the no campaign

The Independence Party leads the opposition. Its leader, Gudrún Hafsteinsdóttir, put the argument bluntly: "What's a seat at the table worth if we don't have the final word?" Since 2009, some labour unions and industrialists have switched to the anti-EU camp, convinced that national control over quotas and territorial waters is the foundation of Iceland's wealth. The fear is that accession would open Icelandic waters to EU fleets under the Common Fisheries Policy, a system that has been contentious in other member states.

Analysts in Brussels suggest the EU may be willing to accommodate Iceland's specificities. "I believe there would be a willingness to accommodate Iceland's special context, that includes also natural resources," Möller said. Iceland would be a net contributor to the EU budget given its wealth, and would require far fewer reforms than the Western Balkan candidates. That leverage could secure transitional arrangements or permanent exemptions on fisheries and agriculture, though nothing is guaranteed until negotiations begin.

What the EU gets from Iceland

From the EU's perspective, Iceland is an unusually easy candidate. It already applies most single-market rules through the European Economic Area, participates in Schengen, and aligns its foreign policy closely with the bloc. Accession would formalise influence over a strategic North Atlantic gateway without the years of institution-building required elsewhere. The European Commission has signalled openness to a swift process, though the final say rests with member states, several of which have their own fishing interests to protect.

The EU enlargement policy has stalled in recent years, with Western Balkan candidates stuck in long negotiations and Turkey's process frozen. Adding a high-income, rule-of-law-compliant member would be a political signal that the union can still expand. But the Commission will be wary of setting precedents for sectoral opt-outs that other candidates, or existing members, might demand.

The two-step process ahead

A yes vote on Saturday does not mean Iceland joins the EU. It triggers a negotiating mandate. The government would then seek a formal accession treaty, covering 35 policy chapters, which must be ratified by all 27 member states and the European Parliament. Only then would a second referendum be held on the final deal. The foreign minister has estimated 18 months for negotiations, though past enlargements have taken far longer. The krona would remain until euro adoption criteria are met, a separate process that could take years.
