Bank capital buffers increase, still not high enough

``The superstructure of financial reform may be stalled in Congress, but at least regulators are forcing banks to raise capital. Since the nadir of the financial crisis in the fourth quarter of 2008, the Big Four have more than doubled their common equity, raising another $55 billion just in the fourth quarter. The question is whether they’ve raised enough. With capital only a bit above early ‘08 levels, especially among regional banks, the answer is most likely no.''
