Brunei Dollar (BND) Monetary Framework

​​In 2017, BDCB introduced the averaging provision to the banks' reserve requirement, also known as Minimum Cash Balance (MCB) requirement, which provide banks flexibility in their liquidity management. BDCB also conducts monetary operations through the issuance of BDCB ​Islamic Bills (I-Bills) and Overnight Standing Facilities to ensure sufficient liquidity for the smooth functioning of the domestic banking system.

The design of the instruments and operations in relation to the Brunei Dollar (BND) Monetary Framework are strictly consistent with the Currency Board principles to support the monetary policy of the country.

Minimum Cash Balance (MCB)


The MCB requirement is applicable to banks licensed under the Banking Order, 2006 and Islamic Banking Order, 2008.
