Iceland votes on restarting EU accession talks this weekend

Iceland goes to the polls on 29 August for a referendum that could restart the country's path toward European Union membership, thirteen years after a centre-right government pulled the plug on negotiations. The question on the ballot is narrow: "Should Iceland resume accession negotiations with the European Union?" But the implications stretch from Reykjavik's harbour to the Western Balkans, where candidate countries have waited decades for tangible progress.

What the referendum actually decides

A yes vote would not make Iceland an EU member. It would merely authorise the government to reopen talks with Brussels. If those negotiations produced an accession treaty, Icelanders would vote again on whether to ratify it. Prime Minister Kristrún Frostadóttir, who leads the Social Democratic Alliance, has been careful to frame the referendum as an opportunity to discover what terms Iceland could secure, not as a vote on membership itself. Her argument is that the public should be able to judge a concrete treaty text before committing.

This two-step design mirrors the process used for the original application. Iceland applied in July 2009, weeks after the financial crisis exposed the vulnerability of its banking sector and the krona. Negotiations opened in 2010 and proceeded across 35 policy chapters. Then, in 2013, Sigmundur Davíð Gunnlaugsson's government halted them, citing sovereignty concerns over the EU's Common Fisheries Policy. No treaty was ever put to a vote.

Why fisheries remain the sticking point

Fishing is not just an industry in Iceland; it is a pillar of national identity and economic security. In 2023, the fish sector accounted for one third of the country's total goods exports by value. The EU's Common Fisheries Policy, which manages stocks collectively and allocates quotas among member states, is seen in Reykjavik as a threat to that control. The 2013 pause was driven almost entirely by this issue.

Brussels now signals willingness to bend. In April, Costas Kadis, the European Commissioner for Fisheries and Oceans, said there was "definitely room for flexibility" on fisheries policy and confirmed that possible exemptions would be part of any renewed negotiations. The shift reflects Iceland's strategic value in the North Atlantic and Arctic, where great-power competition is intensifying. The EU wants a reliable partner on its northern flank; Iceland wants access to the eurozone to tame the volatile krona, which has kept inflation and interest rates elevated.

How far the previous negotiations got

Iceland would not be starting from zero. Before talks were suspended, negotiators had opened 27 of the EU's 35 thematic chapters and provisionally closed 11. Because Iceland has been in the European Economic Area since 1994, and in the European Free Trade Association since 1970, its laws already align with large swathes of the acquis communautaire, the body of EU treaties, regulations and court rulings that candidates must adopt. That alignment could make the technical phase of renewed talks unusually swift.

The difficult chapters remain. Agriculture and fisheries management, particularly catch quotas, are likely to be contentious and time-consuming. Marta Kos, the European Commissioner for Enlargement, has described Iceland as a "strong and strategic partner," but the Commission will still demand full compliance on the chapters that remain open. The speed of progress will depend as much on political will in EU capitals as on technical readiness in Reykjavik.

The geopolitical calculation on both sides

For the EU, Iceland's bid arrives at a moment when enlargement has returned to the agenda after years of stagnation. Russia's full-scale invasion of Ukraine in 2022 forced a rethink: a Europe "whole and free" is no longer a slogan but a security imperative. Montenegro is now targeting membership by 2028, and the Commission is engaging more seriously with other Western Balkan candidates. Iceland's application, if it moves forward, would be the first from a wealthy, fully integrated EFTA state in decades, a test of whether the enlargement machinery can still deliver results.

For Iceland, the calculation mixes economics and security. The krona's volatility has been a persistent headache; euro adoption would eliminate exchange-rate risk and likely lower borrowing costs. But joining the eurozone requires EU membership first. Meanwhile, Arctic geopolitics, new shipping routes, resource competition, military presence, make a formal EU anchor attractive. The government's challenge is to convince a sceptical electorate that the trade-offs are worth it.

What enlargement momentum means for the Western Balkans

Western Balkan countries, Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, Serbia, have been told for years that their future lies in the EU. Progress has been glacial. Montenegro, the furthest advanced, only recently regained momentum toward a 2028 target. The European Council's 2023 decision to open negotiations with Ukraine and Moldova, and to grant candidate status to Georgia, shifted the political atmosphere. But the mechanics of enlargement, unanimous member-state approval at every stage, chapter-by-chapter benchmarks, the threat of bilateral vetoes, remain cumbersome.

Amanda Thorpe of the Atlantic Council argues that Iceland's bid could prove the system works. Each candidate rises or falls on its own reforms, but a successful Icelandic accession would demonstrate that the EU can still admit new members. That matters for credibility in the Balkans, where frustration with the process has fuelled democratic backsliding and opened space for external influence from Russia, China and Turkey.

Political risks that could still derail the process

Even if Iceland votes yes, the path is littered with tripwires. Accession requires unanimous assent from all 27 EU member states. Some capitals want to tie further enlargement to internal EU reforms, changes to voting rules, budget contributions, institutional architecture, that are themselves fiercely contested. That debate could stall any Icelandic treaty for years.

Domestic politics in Europe add another layer of uncertainty. Marine Le Pen, a frontrunner in France's 2027 presidential election, opposes further enlargement. A Le Pen presidency could block or slow the process at the European Council. In Iceland, opposition parties could campaign against a future treaty, or a future government could hit pause again, as happened in 2013. James Batchik of the Atlantic Council notes that political considerations on both sides of the negotiation table may ultimately determine the pace more than technical readiness.
