The Basel III framework developed in the aftermath of the financial crisis has made fundamental changes in regulatory capital requirements applicable to banks and other financial institutions. Risk weightings of securitization have come into particular focus as part of this exercise, with the Basel Committee finalizing its securitization framework at the end of 2014 which comes into effect in 2018. Both the EU and the US have also finalized their approach to securitization risk retention with a somewhat different approach between the two regimes. There have also been recent efforts, including as part of the EU’s Capital Markets Union initiative to seek to reinvigorate the securitization market, including a more favorable capital framework for simple and transparent securitizations. This seminar will consider all these developments and the effect of the differences in approach between the EU and the US.
