A monetary policy that “leans against the wind” may contribute to greater stability in the longer term, as the purpose of trying to prevent financial imbalances from building up is that they should not cause problems with financial or macroeconomic stability at some point in the future. Most people agree that monetary policy should not have the main responsibility for preventing financial imbalances, but that this should rest on micro- and macroprudential policy and a well-designed regulatory framework. A central issue is, however, what support to prudential policy and the regulatory framework monetary policy needs to provide so that they can fulfil their tasks. 5 I do not believe it is possible to completely ignore financial stability when conducting monetary policy. Different views in research and among central banks There is on the one hand a growing research-related literature on whether central banks should “lean against the wind” – or conduct “prudential monetary policy”, as it is sometimes called and which perhaps is a more telling term. 6 There is on the other hand a more practical policy discussion.
Concerning the intensive debate about the Riksbank’s policy, my conclusion was that it can be useful to have a system where the monetary policy remit and policy objective are reviewed at regular intervals, as is currently the case in for example Canada. This would create better understanding and legitimacy for the monetary policy conducted and clarify that the central bank actually only performs the remit it has been given. I also believe it can be a way to counteract the forces that seem to exist in many parts of the world to make central banks less independent. As regards the decline in cash use, there are not so many conclusions to draw as yet. What we can say for certain is that an e-krona would affect the conditions for monetary policy quite substantially, more or less regardless of how it is designed. It is wise that many countries are examining the scope for introducing e-money, as one of the lessons that after all can be learnt from developments in Sweden is that cash use in society can decline very rapidly. These were the experiences and reflections I wanted to share with you. Perhaps the conclusions I draw are not that spectacular. But I would like to believe that the observations and experiences that we practitioners and economic policy decisionmakers make in our day jobs, so to speak, slowly but surely help to enhance the level of our collective knowledge. My hope is that this could at least be a small contribution to this development.
