But why did the regulators, knowingly, tempt the bankers?
Where Tett falls short though is in the reconstructing of the scene of the crime, since nowhere does she ask herself why the regulators exposed the bankers to these types of temptations, especially when they must have known they would fall for them.
My personal answer is that the regulators were so obsessed with fighting their own demons, “the default risks”, so that they did not care for anything else; and neither did they want or listen to other opinions, since they wanted to show themselves to be independent.
If there is one single lesson that stands out from the current turmoil it is that the regulation of the financial sector cannot be left solely in the hands of the regulators, since single-mindedness is not a good enough reason to award anyone independence.
