The National Bank of Angola establishes the BNA Rate as a monthly-defined basic interest rate to signal monetary policy and serve as the benchmark for interbank rates. Issued by Governor José de Lima Massano in Official Gazette Series I No. 63 on April 2, this Notice takes immediate effect and assigns interpretive authority to the Asset Markets Department. The framework ensures consistent market signaling by mandating monthly rate definitions and providing a clear reference mechanism for interbank lending.
