The Swedish Krona — Currency, History & the Euro Question
The krona (crown) (plural: kronor (crowns), abbreviated SEK) has been Sweden's currency since 1873. It is one of the oldest currencies still in circulation and remains a point of national pride — so much so that Swedes voted decisively to keep it when given the chance to adopt the euro in 2003.
The 2003 Euro Referendum
Sweden joined the European Union in 1995 and technically committed to adopting the euro — there is no formal opt-out (unlike Denmark). However, a referendum on 14 September 2003 saw Swedes reject euro adoption by a decisive 55.9% to 42.0%.
The campaign was marked by tragedy. Just three days before the vote, Foreign Minister Anna Lindh was fatally stabbed in a Stockholm department store. The referendum proceeded as planned, and the result was a clear "no."
Opponents argued that the krona gave Sweden monetary policy independence — the ability to set interest rates appropriate to Swedish conditions rather than those of the eurozone as a whole. Supporters countered that euro adoption would reduce transaction costs and integrate Sweden more deeply with its largest trading partners.
Since 2003, no government has moved to revisit the question. Public opinion has fluctuated but has generally remained sceptical of euro adoption, particularly after the eurozone debt crisis of 2010–2012. The Riksbank continues to set its own monetary policy, targeting 2% inflation.
The Riksbank — World's Oldest Central Bank
The Sveriges Riksbank (The Riksbank of Sweden) is the world's oldest central bank, founded in 1668 — predating the Bank of England by 26 years. Originally established by parliament to restrain the crown's tendency to debase the currency, the Riksbank has evolved into a modern, independent central bank with a mandate focused on price stability.
The Riksbank sets the repo rate (its key policy rate), manages foreign currency reserves, oversees the payments system, and is responsible for the issuance of banknotes and coins. It has also been at the forefront of research into central bank digital currencies, with its e-krona pilot project exploring a potential digital complement to physical cash.

Exchange Rates and Purchasing Power
For UK visitors and business travellers, the krona's exchange rate is a practical consideration. In recent years, the rate has fluctuated between SEK 10 and SEK 13 per pound sterling. The krona weakened significantly in 2022–2023 before partially recovering.
Sweden is generally more expensive than the UK for day-to-day living. The Big Mac Index — The Economist's informal purchasing power comparison — typically shows Sweden 15–20% above the UK. Dining out, accommodation, and alcohol (purchased through the state monopoly Systembolaget) are notably pricier. However, many cultural attractions and nature experiences are free, and the quality of public services is high.

Banknotes and Coins
Sweden's current banknote series, introduced in 2015–2016, features prominent Swedes:
- 20 kr: Astrid Lindgren (author of Pippi Longstocking)
- 50 kr: Evert Taube (troubadour and poet)
- 100 kr: Greta Garbo (film star)
- 200 kr: Ingmar Bergman (film director)
- 500 kr: Birgit Nilsson (opera singer)
- 1,000 kr: Dag Hammarskjöld (UN Secretary-General)
The previous series featured Carl Linnaeus (100 kr) and King Gustav Vasa (1,000 kr). The shift from royalty and scientists to cultural figures reflected a deliberate choice to celebrate Sweden's creative heritage.
Coins remain in circulation in denominations of 1, 2, 5, and 10 kronor. The smaller öre (a hundredth of a krona) subdivisions were phased out — 50 öre coins were the last to go, withdrawn in 2010. All transactions are now rounded to the nearest krona.
The Declining Role of Cash
Perhaps the most striking aspect of the krona's modern story is how rarely Swedes actually handle it in physical form. Sweden is the world's most cashless society — in 2024, cash was used in fewer than 8% of retail transactions. Many shops, restaurants, and even churches display signs reading "Vi tar inte kontanter" ("We don't take cash").
The Riksbank has expressed concern about this trend, not because it opposes digital payments, but because it raises questions about financial inclusion, resilience in crisis scenarios, and the role of the central bank itself. The e-krona project is, in part, a response to this challenge.
Investment and Markets
The Stockholm Stock Exchange (Nasdaq Stockholm) is one of Europe's most active markets, home to major corporations including Volvo, Ericsson, H&M, AstraZeneca, and Atlas Copco. The OMX Stockholm 30 (OMXS30) index tracks the 30 most-traded stocks.
Swedish household investment culture is notably active. The investeringssparkonto (investment savings account) (ISK), introduced in 2012, provides a tax-efficient wrapper for equity investments and has been widely adopted, contributing to one of the highest rates of retail equity ownership in Europe.
Looking Ahead
The krona's future is likely to remain independent. Euro adoption is off the political agenda for the foreseeable future. The more interesting question is what role the physical krona will play as Sweden moves ever deeper into digital payments — and whether the e-krona will become the world's first operational central bank digital currency from a major Western economy.
For now, the crown endures — a small currency with an outsized story.
