A Bank rate is the interest rate that is charged by a country’s central or federal bank on loans and advances to control money supply in the economy and the banking sector. This is typically done on a quarterly basis to control inflation and stabilize the country’s exchange rates. A fluctuation in bank rates triggers a ripple-effect as it impacts every sphere of a country’s economy. For instance, the prices in stock markets tend to react to interest rate changes. A change in bank rates affects customers as it influences prime interest rates for personal loans.
