The currency used in Sweden is the Swedish Krona (SEK). The currency symbol is "kr," and it is divided into 100 öre. The Swedish Krona has been in use since 1873, replacing the previous currency known as the riksdaler. In Sweden, both cash and digital payments are commonly used, with a significant shift towards electronic transactions in recent years. The Krona's value fluctuates in the foreign exchange market, making it an important subject for traders and economists who monitor the economic conditions in Sweden and the broader Scandinavian region.
