The European Union is nearing a breakthrough on a long-standing barrier to Montenegro's EU membership — the country's use of the euro without formal eurozone status. Officials familiar with the matter say negotiators are close to resolving this unique obstacle that has complicated accession talks. Montenegro's de-facto euro adoption since 2002 has created a complex situation where the Balkan nation uses the currency without being part of the eurozone or having a say in monetary policy.

This currency arrangement has been a sticking point in EU accession negotiations, as it raises questions about monetary sovereignty and economic alignment with EU standards. The euro's use in Montenegro began after the dissolution of Yugoslavia and the subsequent replacement of the German mark. While the arrangement has provided monetary stability, it has also limited Montenegro's control over its own monetary policy and created a unique economic relationship with the EU.

A potential solution would mark significant progress in Montenegro's decade-long EU accession process. The development comes as the EU seeks to expand its influence in the Western Balkans amid growing concerns about Russian and Chinese economic presence in the region. Resolving the euro issue could pave the way for Montenegro to become the EU's 28th member state, strengthening European integration in Southeast Europe.
