Address by Dr Chris Stals, Governor of the South African Reserve Bank, at a South African Financial Markets Conference arranged by Standard Bank of South Africa Limited, Cape Town. 1. Challenge number one - to find consensus on what the objective of monetary policy should be in South AfricaIn the international community of central bankers, there is widespread consensus that the primary goal of monetary policy must be domestic price stability. Price stability, however, is only a means to an end, and not a final goal of overall macroeconomic policy. The ultimate goal is determined by governments and is normally linked to the objective of maximum economic growth, development and the creation of more employment opportunities.Contemporary economic theory supports the view, however, that financial stability, as measured by a low rate of inflation, is a precondition for the attainment of optimum economic development. Furthermore, monetary policy, being only one of the sub-elements of overall macroeconomic policy, is tasked with the responsibility to create and maintain such a stable financial environment that will be conducive for sustainable economic growth at an optimum rate in the medium and longer term.In South Africa, however, confusion remains on what the task and the functions of the central bank should be. The most important delusion, supported by certain business people, politicians and even some academics, is linked to the now defunct Phillips curve approach in terms of which the assumption is made that a higher inflation rate can produce a sustained lift in growth and employment. World-wide experience, as long back as in the 1970's, provided sufficient evidence that the assumed trade-off of higher inflation for lower unemployment could only be exploited over the limited period in which inflation expectations did not fully adjust to the new higher rate of inflation. With a more effective implementation of the theory of rational expectations within modern communities, this limited period has indeed become very short.Another reason why the conventional theory of demand management through the application of monetary policy is no longer appropriate, is the major shift that took place in recent years in macroeconomic management, away from conventional Keynesian demand management to contemporary supply side economics. The Phillips-curve approach is based on the theory of demand-driven inflationary or deflationary conditions. The world-wide situation in the 1970's, when there was a simultaneous rise in inflation and in unemployment in many of the industrial countries, refuted the theory of the trade-off and forced new thinking on particularly the implementation of monetary policy.The present universal approach on monetary policy therefore takes account of the new electronic environment of instant communication leading to a more swift dissection of policy actions and immediate reaction by markets, and of the more general need in most countries to raise production capacity, and not to stimulate demand. In this environment, the appropriate role for monetary policy has been redefined as a responsibility for the creation and maintenance of stable financial conditions that will be reflected in low inflation. This is what central banks can do best to support governmental programmes for overall economic growth and development.In South Africa, considering the many attacks made on Reserve Bank policy during this past year, there is still a major lack of consensus on what the prime objective of monetary policy should be. Unless we can get consensus and support for the almost global approach of contemporary central bank policy, and unless we can agree to pursue these policies also in South Africa, the road to the internationalisation of the South African economy will be rough and difficult. 2. Challenge number two - deciding on an appropriate framework for monetary policyGiven the objective of price stability, each central bank must design a framework or a consistent model within which monetary policy can be implemented, taking accoun
