The Swedish krona is the official currency of Sweden, abbreviated as SEK. It is subdivided into 100 öre, although öre coins are no longer in circulation. The krona has been in use since 1873 and is managed by the Sveriges Riksbank, Sweden's central bank. The symbol for the Swedish krona is "kr." The currency is known for its stability and is often used as a benchmark in the Nordic region. The exchange rate can fluctuate against other currencies, such as the Euro and the US dollar, reflecting economic conditions in Sweden and globally.
