Icelanders will decide on 29 August whether to resume negotiations to join the European Union, in a referendum that's being fought over economics, sovereignty and control of the country's fishing grounds — not US President Donald Trump's expansionist rhetoric or Russian threats in the Arctic.
The vote would restart a process frozen 13 years ago if approved, reopening negotiations with Brussels that were suspended when a Eurosceptic coalition came to power in 2013. But the campaign has centred on blue whiting, mackerel and golden redfish rather than geopolitical drama. For a nation of fewer than 400,000 people, the sea shapes the economy, livelihoods and national identity — and this referendum comes down to fish.
Economics and Sovereignty Collide
Eirikur Bergmann, politics professor at Bifröst University and one of Iceland's best-known political writers, said the referendum is being fought over economics, sovereignty and, above all, control of Iceland's fishing grounds. "Icelanders are split in half," he said, noting that public debate still centres on the benefits of adopting the euro and the risks facing the fishing industry.
Fishing's share of Iceland's GDP is declining, but it still accounted for about 8% in 2024. It remains one of the country's largest export industries and the backbone of many coastal communities. The country successfully defended its maritime claims against the United Kingdom during the three Cod Wars between 1958 and 1976, a history that still resonates.
The main concern for the fishing industry is the EU's Common Fisheries Policy, which manages fishing resources among member states. Shared fish stocks that fall under the jurisdiction of more than one state — with catch quotas divided among them — are the biggest worry for the Icelandic fishing industry, prompting calls for exemptions or special arrangements if the country joins the EU.
Iceland's fishing industry is built around one of the world's most sophisticated quota systems, which sets scientifically based catch limits and allocates fishing rights to each vessel. Quotas can also be traded. For fishermen in coastal towns such as Ísafjörður or Vestmannaeyjar, the question isn't only how much fish Iceland can catch, but also who should have the right to decide who catches it.
Agriculture Faces Similar Fears
Foreign Minister Þorgerður Katrín Gunnarsdóttir said in a recent interview that fisheries and agriculture are likely to become the toughest chapters in any renewed accession talks. Farmers also operate under one of Europe's most protected agricultural systems, supported by public subsidies designed to compensate for Iceland's harsh climate and small domestic market.
The feared acronym for them is CAP, the EU agriculture overhaul that distributes subsidies according to common rules and could disrupt the domestic system. Supporters of EU integration are betting on economic advantages, especially the eventual adoption of the euro, which they say would eliminate exchange-rate volatility caused by the Icelandic krona and bring down inflation, interest rates and the cost of international trade, as highlighted in a recent OECD report.
Geopolitics Takes a Back Seat
The renewed interest in Europe isn't a response to Trump's repeated statements about Greenland and expansion ambitions in the Arctic region. While the United States has long been Iceland's principal security guarantor through NATO and cooperation with the EU becomes more attractive if Washington becomes less predictable, the security issue has neither shaped domestic politics nor dominated the referendum debate.
Bergmann said, "I wouldn't say that has properly filtered into the debate yet." He added that the country decided to hold the referendum after the 2024 election. "This is prior to the second term of Donald Trump and prior to these geopolitical changes. The security defence issue was not a part of that decision," he said.
The referendum is the consequence of a change in government rather than a dramatic shift in public opinion. A Eurosceptic coalition came to power in 2013, suspending negotiations and later withdrawing Iceland's application altogether without consulting the electorate. The pendulum swung back in 2024, and a coalition of pro-European parties pledged to let Icelanders decide whether negotiations should resume.
Bergmann said, "The only reason Iceland is moving ahead now is that we have a change in government. But the EU question had nothing to do with these parties coming to power." He said opinion polls remain finely balanced, with Icelanders revisiting a question that has divided the country since the early 2000s.
Trump and Russian President Vladimir Putin may have reminded Iceland that the international order is changing, but voters entering polling stations are likely to think less about Greenland or Russia's ambitions in the Arctic than about domestic economic concerns.
A Smoother Path Than Most Candidates
Iceland would probably face a smoother accession process than many candidate countries in the Western Balkans or Eastern Europe. It's already deeply integrated into Europe through the European Economic Area and enjoys free movement of people, goods, services and capital within the Schengen area.
Negotiations wouldn't start from scratch. By the time Iceland withdrew its application in 2013, 27 negotiating chapters had been opened and 11 had been provisionally closed. If negotiations resume, the European Commission will first need to assess the legislative changes that have taken place in Iceland over the past decade before discussions can formally restart.
An EU official told Euronews, "Beyond the technicalities, it is clear that Iceland would be going into the negotiations one step ahead, compared to another candidate country." Valérie Hayer, leader of the liberal Renew Europe group in the European Parliament and one of the staunchest supporters of Iceland's accession, said the Nordic country is already largely aligned with the EU on democratic standards. "It is already a highly capable democratic partner (which) shares common values and (which) already plays a pivotal role in North Atlantic security," she said, claiming that adding Reykjavík would reinforce the EU's geopolitical reach.
European politicians and EU officials stressed that Iceland has nothing to lose in EU membership talks and that joining the Union poses no threat to the Icelandic language, which would enjoy the same official status as other EU languages despite being spoken by fewer than 400,000 people. Even so, for many Icelanders, the referendum raises deeper questions of identity. Some fear joining a supranational institution would result in a gradual erosion of Iceland's political autonomy, a particularly sensitive issue for a country that achieved full independence from Denmark in the 20th century.
The future of Iceland's relationship with Europe may ultimately depend on emotional considerations, another EU official familiar with the matter told Euronews. "Voting will take place on the mainland, but people will vote looking at the sea."
Why This Matters:
Iceland's referendum reveals the tension between economic integration and local autonomy that defines EU enlargement in the 21st century. For a small nation with a sophisticated fishing quota system and a fiercely protected agricultural sector, joining the EU means navigating the Common Fisheries Policy and CAP — frameworks designed for continental economies, not island nations with unique resource management traditions. The outcome will test whether the EU can offer flexible arrangements that respect national systems while delivering the economic stability that euro adoption promises. It's also a reminder that geopolitical drama doesn't always drive European politics — domestic concerns about livelihoods, subsidies and who controls natural resources often matter more to voters than security threats or great power posturing. If Iceland votes yes, it would strengthen the EU's presence in the North Atlantic and add a highly aligned democratic partner. If it votes no, it will be because fishermen in coastal towns decided Brussels can't be trusted with their quotas.
