If forceful measures are not taken to deal with the financial crisis and maintain financial stability, there is a risk of the crisis also having major effects on inflation and growth. The fall in output and employment can then be both deep and prolonged and that in turn can worsen the financial crisis. An efficient fixed-income market is a prerequisite for an effective monetary policy In other words, the monetary policy machinery I have described consists of two components. The first thing is to ensure that the repo rate does in fact affect the overnight market. Effects on this shortest rate must then spread to longer rates that are more important for economic activity. An effective monetary policy steering system is not enough by itself. We also need a fixed-income market that functions properly. So what are the fixed-income market’s functions? The fixed-income market caters both for those who need funds for their operations and for those with funds they need to invest for a certain period of time. As investment in the market is not risk-free, one of the market’s primary tasks is to price risk correctly. That in turn leads to an optimal distribution of risks between the markets’ participants. In this way the market contributes to an efficient distribution of economic resources. What a central bank requires of the fixed-income market is therefore not all that different from what society in general requires.
Memorandums of Understandings or information-sharing protocols would then be used to ensure the free sharing of information between agencies. The analytical skills and tools required for macroprudential policy are likely to draw on those used for macroeconomic analysis and, to a lesser degree, microprudential analysis. But the  7  This argument is developed by Martin Cihák in a speech “Price stability, financial stability and central bank independence”, 38th Economics Conference of the Oesterreichische Nationalbank, 2010. A number of case studies illustrating how inadequate independence arrangements for financial sector regulators and supervisors have contributed to the emergence and scale of financial crises are presented by Marc Quinton and Michael W. Taylor in “Regulatory and supervisory independence and financial stability” IMF Working Paper, WP/0246, 2002. 6  BIS central bankers’ speeches  macroprudential agency will need to build new analytical techniques. Before the crisis, many central banks had already begun to develop the type of system analysis that will be required for macroprudential supervision (for example, in the assessment of interdependencies and systemic risks included in financial stability reports) – but the analytical techniques remain in their infancy. Control over a sufficient set of tools As well as the information and knowledge necessary for effective analysis, the macroprudential agency must have access to suitable instruments in order to achieve its mandate. Otherwise there will be unreasonable expectations of what the macroprudential agency can achieve, as it may be unable to address the system-wide risks that it identifies.
