Six years on, we still haven't learned the real lessons from Lehman collapse
Andrew Sheng says regulators fail to understand that the world needs equity, not more debt

On Monday, it will be six years since the collapse of Lehman Brothers. With the US economy still operating below par and Europe struggling to stay above water, the question is whether the right medicine was given after 2008.
The mainstream diagnosis was that the problem lay in excess credit and there was a need to control banks and shadow banks through more regulation and capital. Since politicians were not willing to push fiscal policies to the limit, central bankers opted for massive quantitative easing to stimulate the economy and simultaneously tighten regulation to restrain the naughty bankers.
But who allowed the excess credit in the first place to create asset bubbles at excessively low interest rates before 2007?
