This chapter identifies some of the potential legal and policy issues involved in the future regulation of over-the-counter (OTC) derivatives. First, regulators must be cautious in the regulation and solvency of some mammoth clearing- houses. Second, Singapore and Hong Kong both face challenges in the areas of global regulatory cooperation and extra-territorial regulatory effects. Third, the exact scope of a clearing obligation determines whether there is any regulatory competition or room for regulatory arbitrage in the future. Fourth, there are legal definition problems with the term ‘derivative’ and its sub-categories that must be addressed. Fifth, there are potential privacy and civil liability issues in relation to trade reporting.
