INTRODUCTION

One of the motivations for Basel II had been the fact that the lack of risk-sensitivity in the capital-adequacy rules under Basel I has prompted many banks to do “regulatory arbitrage” mainly through securitisations. Regulatory arbitrage is the avoidance of minimum capital charge through sale or securitisation of a bank’s (high-quality or highly diversified) assets, for which the true risk and the capital requirement imposed by the financial markets is much less than the regulatory capital requirement. From this perspective, developing the right capital rules under Basel II for securitisation tranches becomes all the more important.

The Basel Committee on Banking Supervision (BCBS) had been in a consultation period with regulators, banking practitioners and academics for several years before the actual finalisation of the Basel II Accord. These deliberations were through a series of consultative papers and working papers. There is hardly any aspect of Basel II that has undergone more changes and evoked more active discussions than the capital-adequacy rules for securitisations.
