Icelanders head to the polls Saturday for a referendum on whether to resume European Union accession negotiations, a vote that polls suggest is too close to call and that has taken on new urgency amid U.S. President Donald Trump’s push to acquire Greenland.
The advisory question put to the Nordic nation of nearly 400,000 is straightforward: “Should Iceland resume accession negotiations with the European Union?” If a majority says yes, talks would begin, and any resulting deal would go to a second referendum for final approval.
The vote comes as the Arctic emerges as a strategic flashpoint, with melting sea ice opening new shipping routes and the region drawing attention for its critical mineral deposits. Trump has repeatedly voiced interest in Greenland — Iceland’s closest neighbor — citing national security concerns, and at one point during a World Economic Forum address in Davos earlier this year appeared to conflate Greenland with Iceland.
That mix-up underscored a deeper point, according to Eiríkur Bergmann, a politics professor at Bifröst University in Iceland. “All of the arguments put forth by the U.S. president for why it would be necessary for the U.S. to acquire Greenland actually equally applied to Iceland,” he told CNBC. “The only difference is that Iceland is formally an independent country.”
A security calculus in flux
Iceland — a founding NATO member with no standing military of its own — sits astride the GIUK Gap, the naval chokepoint between Greenland, Iceland, and the U.K. that links the Arctic to the Atlantic. Its defense has long rested on the alliance and a bilateral agreement with Washington dating to 1951.
But trust in the U.S. as a security partner is eroding, Bergmann said, and that is feeding into the referendum debate. “Now many people are sort of reconsidering the validity of that defense agreement,” he said.
Icelandic Foreign Minister Thorgerdur Gunnarsdottir signaled the shifting landscape at the start of the year, arguing in an article for Icelandic newspaper Visir that deeper collaboration with the EU would be key to protecting the country’s interests. “It is clear that the international system we have lived in since the end of World War II is in turmoil,” she said, according to a Google translation.
Domestic drivers dominate
Despite the geopolitical backdrop, analysts stress the referendum is being decided largely on domestic concerns — the economy, sovereignty, and above all fisheries.
Supporters of a yes vote point to the Icelandic krona, a free-floating currency prone to sharp swings, as a key argument for joining the eurozone. The current Social Democrat-led government — the same party that initiated Iceland’s original EU application — is “reheating its bid to close this unfinished business,” said Steven Blockmans, deputy director at the International Centre for Defence and Security think tank.
Opponents include former Prime Minister Katrín Jakobsdóttir, who told CNBC in mid-April that she sees little reason to join, citing Iceland’s existing close economic ties with the bloc and its citizens’ high living standards. “If a majority of the people wants to apply, it is very important to listen to that majority, but I haven’t changed my position,” she said.
Iceland is already deeply integrated with Europe through its European Economic Area membership, which grants access to the EU’s single market without full membership, and its participation in the Schengen Area’s passport-free travel zone.
A test case for the EU
For Brussels, the vote offers a potential success story after Britain’s departure in 2020. Bergmann noted that a yes vote could lead to relatively swift negotiations, given Iceland’s coalition government faces a general election no later than August 2028.
“Bigger is better in this day and age, it seems,” Blockmans said. Welcoming a country with one of the world’s highest GDP per capita and a top-tier democratic record would “give extra shine to the European integration project,” he added.
