The effects of interest rate surprises on banks are different when nominal interest rates are very low. This column reveals how, in ‘normal’ times, policy rate announcements that are below market expectations tend to boost banks’ stock prices on average. When interest rates are very low, however, there is a reversal of this effect, with negative rate surprises reducing banks’ stock prices. This negative impact is larger for banks whose funding relies more on retail deposits than on other sources of funding.
