To get the agreement of the 27 countries engaged in the talks to set new banking rules, the new Basel III banking rules are being phased in over a protracted period. Some changes go into effect in 2013, but others will be put into effect by 2019. The focus on the new rules is how much capital, or "common equity" banks will be required to hold as a cushion to absorb losses in a crisis like that of 2008. Large banks will be required to hold 7% of their assets in common equity. By 2015, banks will have to begin building a 2.5% buffer of capital, which must be in place fully by 2019. No action was taken on issues such as requirements for banks to have access to ample liquidity, what systemically important banks should hold in capital, and establishing a counter cyclical capital buffer.
