It is effects of this type that are referred to in the international debate when arguing that the policy rate is far too blunt an instrument to counter financial imbalances. Sweden's experiences also suggest that the policy rate cannot always be expected to be available for this purpose. Even when a central bank is leaning quite moderately against the wind, such a policy could be in conflict with the task of maintaining confidence in the inflation target. Here too, of course, the question arises of whether it is really so important to maintain confidence in the inflation target. Would it not be possible for monetary 7 [20]  policy instead to just lean against the wind and let inflation develop as it will? Once again, I will return to this shortly. Before continuing, I would like to add that there is a growing amount of research that explicitly attempts to calculate the costs and benefits of using the policy rate to attempt to counteract financial imbalances. The debate is ongoing and the jury is still out. 13 Of course, in this context, the view I present here should only be seen as a country-specific case study. But considering that practical experience of this type of policy is very limited, reflections from someone who has been involved in taking decisions in a country that is ‘ahead in the cycle’ may perhaps be of some value.
Structural factors can push inflation down in a way that can be difficult to counteract for a relatively long time, even if not permanently. It is therefore quite an important discussion that the Borio camp has initiated. 18 How should a central bank act in a situation in which, despite conducting the most expansionary policy it deems possible, it does not expect to be able to reach the target in a foreseeable time frame? As I see it, the reasonable decision in such a situation is to hold fast to the inflation target and continue with the expansionary policy. 19 If the central bank instead were to change its policy in a less expansionary direction, the inflation target would become even more distant and even more  17 Friedman (1963). It should be mentioned that, according to the so-called ‘fiscal theory of the price level’, fiscal policy has crucial influence over inflation, see for example Christiano and Fitzgerald (2000). To achieve low and stable inflation, a well-balanced monetary policy is therefore insufficient. It also requires fiscal policy to be conducted in a way that is compatible with the inflation target. However, this theory is controversial and does not actually question the value of central banks having inflation targets. 18 It should be emphasised that the BIS, where Borio is chief economist, has often been early to bring up issues of fundamental importance for central banks.
