In the analysis of potential future paths, we have to distinguish between policy rates and market rates. Market rates, in general, respond faster to changes in the economic situation and outlook than policy rates. The low inflation environment, subdued economic outlook and downside risks that prevail all warrant the continuation of a very accommodative monetary policy with low interest rates. Given the fragile state of the global economy, a premature increase in policy rates would carry the risk of choking off the recovery. In Switzerland, specifically, the subdued inflation outlook (chart 17), the highly valued currency and the fact that a recurrence of financial market tensions cannot be excluded warrant a continuation of the minimum exchange rate policy. In the current situation, the minimum exchange rate remains an essential instrument for preventing an undesirable tightening in monetary conditions should the upward pressure on the Swiss franc intensify again. Market rates are still determined by the current cyclical weakness of the global economy. Once the global economy gets back on a stronger and broader-based growth path and uncertainty wanes, rates should return to more normal levels. For Switzerland, this would mean that safe haven forces would become less relevant, removing some of the additional negative pressures on domestic interest rates. Conclusion In sum, given that we expect a slow, but continued improvement of the world economy, market rates are set to gradually recover to more normal levels over time.
Third, financial stability may be in danger when strong action by central banks during a crisis leads market participants to rely excessively on central banks as a backstop in case of negative shocks. This is the moral hazard problem.9 Taken together, these channels underline the risks the current “low-for-long”-situation presents for financial stability. These risks have to be acknowledged and acted upon. The fact that it is possible for these risks to exist while monetary policy is responding appropriately to the macroeconomic situation perfectly illustrates the Tinbergen principle – the number of instruments must equal the number of policy goals.10 In the current environment, the interest rate cannot be the instrument of choice for addressing financial stability risks. The answer is to give more weight to what are known as macroprudential instruments implemented as a complement to, and along-side a monetary policy that remains firmly focused on price stability. These instruments directly target the risk-taking behaviour underlying financial stability risks. This is exactly the approach chosen in Switzerland with the activation of the countercyclical capital buffer. By forcing banks to build up additional capital in the current phase of strong credit growth, the regulators aim at improving the capacity of the banking system to bear losses in the event that the identified risks materialise, while also limiting the further build-up of these risks. Outlook We are now in a position to derive the implications of our analysis for the interest rate outlook.
