Key interest rate

The Central Bank conducts monetary policy largely by affecting money market interest rates, mainly through the interest rates on the facilities it offers to credit institutions, which then affect other market rates. The Bank’s key interest rate (sometimes called the policy rate) is the rate on these facilities that is the primary determinant of short-term market rates and therefore of the monetary stance. At present, the Bank’s key rate is its seven-day term deposit rate.

Key interest rate (policy rate) of different type from time to time

The interest rate that has the strongest effect on short-term market rates and is therefore considered the Central Bank’s key rate may change from time to time. Prior to the financial crisis of autumn 2008, the Bank’s key rate was the rate on its collateralised loans to financial institutions. In the wake of the crisis, however, demand for Central Bank loans has been limited, and credit institutions have increased their deposits with the Bank. As a result, the interest rate on the Bank’s deposits has had greater influence on money market rates since 2009.
