The Board of Commissioners of Currency Malaya, came into being in October 1938 following the Blackett Report which recommended that the sole power of issuing currency for the various Malay States, including Brunei, and the Straits Settlements should be entrusted to a pan-Malayan Currency Commission. Sir Basil Phillott Blackett was appointed in 1933 by the Secretary of State for the Colonies to lead a commission to consider the participation of the various Malay States, including Brunei, in the profits and liabilities of the Straits Settlements currency. The Blackett Report was adopted by the Government of the Straits Settlements, the Federated Malay States, Unfederated Malay States and Brunei. Legislation was enacted by the Straits Settlements Currency Ordinance (No. 23) of 1938, and ratified by the various states during 1939. The board started to issue currency in 1939.
In 1952 the board was renamed the Board of Commissioners of Currency, Malaya and British Borneo.
The Currency Ordinance No. 44 of 1952 of the Crown Colony of Singapore, No. 33 of 1951 of the Federation of Malaya, No. 10 of 1951 of North Borneo and No. 1 of 1951 of Sarawak implemented an agreement between those governments and the State of Brunei for the establishment of a Board of Commissioners of Currency to be the sole issuing authority in British Malaya and British Borneo.
On 12 June 1967, the currency union came to an end and Malaysia, Singapore and Brunei each began issuing their own currencies. The currencies of the three countries were interchangeable at par value under the Interchangeability Agreement until 8 May 1973 when the Malaysian government decided to terminate it. Brunei and Singapore continue with the Agreement until the present day.
The Board of Commissioners of Currency Malaya and British Borneo was officially wound up on 30 November 1979.
