We explore the impact of low and negative monetary policy rates in core world economies on bank lending in four small open economies – Canada, Chile, the Czech Republic and Norway – using confidential bank-level data. Our results show that the impact on lending in these small open economies depends on the interest rate level in the core. When interest rates are high, monetary policy cuts in core economies can reduce credit supply in small open economies. In contrast, when interest rates in core economies are low, further expansionary monetary policy increases lending in small open economies, consistent with an international bank lending channel. These results have important policy implications, suggesting that central banks in small open economies should watch for the impact of potential regime switches in core economies’ monetary policy when rates shift to and from the very low end of the distribution.

To shed light on the interaction between macroprudential and monetary policies, we study the inward transmission of foreign monetary policy in conjunction with domestic macroprudential and monetary policies in Norway and Sweden. Using detailed bank-level data we show how Norwegian and Swedish banks' lending reacts to monetary policy surprises arising abroad, controlling for the domestic macroprudential stance and the interaction between monetary and macroprudential policies. In both countries, the domestic macroprudential policy helps mitigate the effects arising after foreign monetary surprises.

Several countries face the choice between targeting inflation independently or entering a monetary union that targets inflation. The present paper extends the theory of optimum currency areas to deal with this choice. In contrast to the conventional theory, countries are shown to form more of an optimum currency area the more asymmetric supply shocks are.
