During the eighties and the beginning of the nineties, several countries experienced serious banking crises. Such proliferation of the problems of the large-scale banking sector has caused widespread concern. Indeed, banking crises undermine the functioning of the financial system and the economy in general. Most countries have tried to underpin the consequences of banking crises through various types of intervention ranging from the pursuit of accommodative monetary policy to the bailout of insolvent financial institutions with public funds. However, even when carefully designed, rescue operations have several disadvantages. The purpose of this paper is to assess the regulatory environment of banks, a decade after the Asian crisis. We will identify the factors relating to banking supervision contributing to the triggering of crises in emerging countries in the years 1990s and see if the countries have improved their regulation in 2007 and which coincided with the subprime crisis. For this, we have studied a sample of 105 developed and emerging countries over two years, 1997 and 2007.
