The official currency of Sweden is the Swedish Krona (SEK) . The krona is divided into 100 öre, which is equivalent to pennies or cents. Banknotes are printed in values of 20, 50, 100, 200, 500, and 1,000 kronor, while coins are available in denominations of 1, 2, 5, and 10 kronor. It is important to note that older versions of the 20, 50, and 1,000-kronor banknotes, as well as the majority of older coins, are no longer valid. Therefore, it is recommended to check the validity of the currency before using it. Sweden has yet to ratify the Euro treaty, which means that you cannot pay using euro (€) or other currencies than SEK in cash. However, some tourist shops in Stockholm and some hotels, usually those owned by big international chains, accept euros. It is best to take Swedish Krona to Sweden, but if you cannot buy some before your trip, the next best option is to bring US dollars (USD), Euros (EUR), or Pounds (GBP) .
