Source: According to a report on the website of The Economist in Spain on October 23rd, due to not using the euro, it is officially stated that Sweden has been in a controversial legal dilemma in Europe for 20 years. The Nordic country belonging to the '27 country club' has been using its own currency for decades and is a controversial issue in both Brussels and Stockholm.
The reason for this strange situation can be traced back to 2003. That year, the country prepared a referendum on whether to adopt the euro. However, the results poured cold water on the efforts of pro European factions in Sweden, with only 42% of voters supporting the euro and 56% demanding the retention of the Swedish krona. Since then, Sweden has been in the same position, within the European Union, and has been officially required to use the euro, but the country has "postponed" the adoption of the euro. Due to the willingness of the Swedish people to maintain their monetary sovereignty, this delay lasted for 20 years.
More specifically, currently all political parties in the Swedish parliament, except the Liberal Party, are in favor of maintaining their currency, and the reasons have not changed since the beginning. Politicians who have expressed support for maintaining their own currency say they hope to maintain effective control over monetary policy so that they can make decisions different from those in Europe in the event of a crisis. In addition, these representatives believe that they have achieved good economic performance under the current model, especially during turbulent times, and therefore believe that changing this model is risky.
The report states that Sweden is not the only country in the European Union that does not use the euro, and Denmark also does not use the euro.
