What is Bank Negara Malaysia Overnight Rate (BNM_OPR)?

Bank Negara Malaysia Overnight Rate is a central bank policy rate — the interest rate at which a country's central bank lends money to commercial banks. It is the primary tool used by monetary authorities to control inflation, stabilize the currency, and influence overall economic activity.

Central bank rates serve as the floor for all borrowing costs in an economy. They directly influence mortgage rates, consumer loans, corporate bonds, and the exchange rate. Investors, economists, and financial institutions closely monitor these rates as leading indicators of monetary policy direction.
