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.

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.

But he stressed that in the meantime the UK should nevertheless prepare - not only for introduction of the euro on the Continent on 1 January 1999 - which we of course did very effectively - but also for our own eventual participation. The Chancellor’s statement was the first by a British Government to accept the principle of monetary union. It recognised that the single currency will affect us whether we are in fact in or out - and that it is clearly in our own national interest to do all that we can to ensure that the euro is successful.
