Bloomberg reported the world’s largest banks will have to build up their loss-absorbing liability buffers to see them through a crisis, as regulators tackle too-big-to-fail lenders six years after the collapse of Lehman Brothers Holdings.

Bloomberg notes the biggest banks may be required to have total loss absorbing capacity equivalent to as much as a quarter of their assets weighted for risk, with national regulators able to impose still tougher standards.
