Several central banks implemented negative policy rates in response to the financial crisis, but there is little consensus on the overall effect of this policy. This column examines the transmission of policy rates to bank lending rates, focusing on the case of Sweden. While the first two cuts in negative territory by the Riksbank appear to have been transmitted to lending rates, transmission seems to have broken down for the second two cuts. The findings suggest diminishing returns on interest rate cuts at negative rates.
