There is still considerable debate amongst Islamic scholars about the acceptability of the various forms of derivative products from the perspective of Islamic jurisprudence. Hence, there is a need for more investment in intellectual capital in the field of Islamic finance to promote innovation that  BIS Review 11/2004  3  integrates the appropriate Syariah principles within the Islamic financial instruments. Our efforts to keep abreast with such developments will facilitate more rapid development of Islamic financial instruments for the purpose of risk management, using derivatives. It is evident that the derivatives business has global opportunities since risk in today’s financial environment is a product of uncertainties prevailing in the global markets, whether financial or non-financial. The ISDA Master Agreements have been the universal means of bringing order and certainty to the complex and rapidly developing world of OTC derivatives.

We need more surgical instruments, namely an effective macro-prudential policy framework. For example, tools such as loan-to-value ratios or debt-to-income ratios could be used to limit credit misallocation to non-productive sectors, without at the same time harming sectors where capital needs to flow. Conclusion Let me conclude. Real economic convergence supports the cohesion and smooth functioning of monetary union. What I have tried to illustrate today, however, is that there are no shortcuts to achieve it – and least of all by riding the upswing of the financial cycle. As Hyman Minsky demonstrated, what goes up must sadly come down. One way to begin a more sustainable convergence process, in the near term, is through reallocating resources where they are most productive. But the challenge for euro area countries does not stop there. Raising productivity is a complex process that reaches across the economy and into many different policy domains, be they education, judicial systems or administrative capacity.
