As Raguram Rajan summarized in his book “Fault Lines”: “The financial sector is, in many ways, the brain of a modern economy. When it functions well, it allocates resources and risk effectively and thereby boosts economic growth. [...] It works for all of us. Of course, when it works poorly, as has done recently, it can do enormous damage while befitting a very few.”12 Part of the failures was certainly attributable to deficiencies in financial regulation and supervision. The regulatory overhaul of the financial sector is intending to correct this and thus help the financial sector to refocus on its servicing role. 10  See Schumpeter, J.A.

We acted swiftly to defeat the manipulators at their own game with a series of measures that threw them off their guard, drove them out of the market, and raised the defences against future attacks. First, drawing on the official reserves, we went into the stock and futures markets. In the second half of August we accumulated $ billion worth of shares: I am happy to say they are now worth $ billion, but our aim was not to make money; it was simply to deter manipulation by making sure that it did not pay off. That objective was achieved. The manipulators were forced to close out their short positions, in many cases with heavy losses. And we followed through with a package of technical measures to strengthen our currency board arrangement to make our money market less susceptible to manipulation. These measures are working well. Further reforms are being introduced in the securities and futures markets to reduce the possibility of market dislocation. Our actions served their purpose of deterring market manipulation. We could not passively sit through the speculative attack and see our markets overshoot to produce profits for the manipulators, and our entire financial system brought to the brink of collapse. We do not pretend that our intervention in the markets was not a controversial act. This was not a decision that we enjoyed taking. It involved many risks, not least among them the risk of being misunderstood.
