Sveriges Riksbank, or simply the Riksbank, is the central bank of Sweden. Founded in 1668, it is the world's oldest surviving central bank, and the third oldest bank in continuous operation. Until the 20th century, it was also the only state-owned central bank outside of the Russian Empire.

A central bank, reserve bank, national bank, or monetary authority is an institution that manages the currency and monetary policy of a country or monetary union. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Many central banks also have supervisory or regulatory powers to ensure the stability of commercial banks in their jurisdiction, to prevent bank runs, and in some cases also to enforce policies on financial consumer protection and against bank fraud, money laundering, or terrorism financing.
