The Bank of Java was a note-issuing bank in the Dutch East Indies, founded in 1828, and nationalized in 1951 by the government of Indonesia to become the newly independent country’s central bank, later renamed Bank Indonesia. For more than a century, the Bank of Java was the central institution of the Dutch East Indies’ financial system, alongside the “big three” commercial banks. It was both a note-issuing bank and a commercial bank.

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.
