The global financial crisis (GFC) that started in 2007 has had a major negative impact on financial markets and the economy in general. The GFC was blamed partly on OTC derivatives and their counterparty risks and opacity, neither of which was well controlled due to the historic light regulation of this market. A clear example of this is the bankruptcy of Lehman Brothers and the close out of the millions of OTC derivatives contracts traded by Lehman (many of which are still subject to legal wrangling several years later). It was therefore not surprising that much of the post-GFC regulatory reform has focused on OTC derivatives and, in particular, the mitigation of counterpary risk.
