In 1951, national fervour gained momentum for the establishment of a central bank as a form of economic sovereignty in the Republic of Indonesia. Consequently, the Government decided to establish the DJB Nationalisation Committee.
The nationalisation process was implemented by the Government of the Republic of Indonesia purchasing 97% of DJB shares.
On 1st July 1953, the Government of the Republic of Indonesia issued Act No. 11 (Principal Act on Bank Indonesia), which superseded the DJB Act of 1922. On 1st July 1953, therefore, Bank Indonesia was officially established as the Central Bank of the Republic of Indonesia.
Act No. 11 of 1953 contained the first laws regulating Bank Indonesia as the central bank.
Bank Indonesia’s duties were no longer restricted to circulation activities but were expanded to include commercial banking activities by providing loans.
During this period, the Monetary Board (MB) was established to determine monetary policy. The MB was chaired by the Finance Minister, with the Bank Indonesia Governor and Trade Minister as members. Bank Indonesia was subsequently tasked with implementing the monetary policy set by the MB.
During the Guided Democracy period, President Soekarno introduced the Guided Economy concept. At that time, the Bank Indonesia Governor was a member of the Parliamentary Cabinet, known as the Minister of Central Bank Affairs, and the Monetary Board was disbanded.
In terms of banking, the Bank Berjoang Doctrine sought to unify all state-owned banks as single presence banks under the name Bank Negara Indonesia (BNI) in accordance with Presidential Regulation (Perpres) No. 17 of 1965.
During implementation of the Bank Berjoang Doctrine, Bank Indonesia became BNI Unit I, while the other state-owned banks became BNI Units II-V.
