Icelanders are set to vote on Saturday in a referendum that could restart accession negotiations with the European Union. The decision comes amid heightened geopolitical instability, with some citizens expressing concerns about the reliability of international partners following recent actions by the United States.

The vote will ask voters a simple yes-or-no question: Should Iceland resume accession negotiations with the European Union? A 'yes' vote would initiate a lengthy negotiation process with the European Commission, involving assessments across 35 criteria, including financial systems, fisheries, and freedoms. Any eventual agreement would require approval from all EU member states and a final vote by Icelanders.

This referendum follows a complex history with the EU. Iceland did not hold a vote on its 2009 application for membership, which was submitted after the 2008 financial crisis. Accession talks were suspended in 2013 and formally ended in 2015. The current center-left government, elected in 2024, included a pledge for a vote on EU membership in its platform.

Central to the debate is the issue of sovereignty, particularly concerning Iceland's lucrative fishing industry. Opponents of EU membership argue that Iceland already enjoys the benefits of European integration through the European Economic Area and the Schengen free-travel zone without surrendering its independence. They emphasize the importance of maintaining control over national laws and resources.

Proponents of joining the EU highlight the security benefits of alignment with a bloc of nations in an increasingly volatile world. They point to smaller EU member states that have found increased strength and security through membership. The potential for economic advantages, such as a more stable euro currency and lower interest rates, is also a factor.

Recent events have amplified concerns about geopolitical stability. U.S. President Donald Trump's repeated, albeit erroneous, remarks about acquiring Greenland, Iceland's neighbor, fueled fears among some Icelanders. The U.S. State Department clarified that Trump was referring to Greenland, but the incidents, along with a remark by the new U.S. ambassador to Reykjavik about Iceland becoming the 52nd U.S. state, have led some to question the predictability of U.S. foreign policy.

Foreign and Defense Minister Thorgerdur Katrín Gunnarsdóttir stated that Trump's actions underscored the importance of like-minded nations standing together, a principle she sees embodied in the European Union.

The Icelandic fisheries, a cornerstone of the nation's economy and cultural identity, remain a significant point of contention. Concerns exist about potentially having to adhere to the EU's Common Fisheries Policy, which could allow other European trawlers access to Icelandic waters. However, proponents are confident that any agreement would include an exemption to protect Iceland's fishing rights, asserting that the country will not sign a deal that compromises its control over this key resource. Skepticism persists, however, regarding the long-term protection of fishing rights, particularly for migratory species.
