There are two reasons for regulating the behavior of international financial dealers and the conduct of international financial markets. One is to moderate and restrain greed and the other is to moderate and restrain fear. Greed and fear are the two human emotions most evident in the day-to-day behavior of the international financial system today. The result is mad money. Dealers are either drawn by greed to take excessive risks with their own – or, more often, with other people’s – money or they are overcome by fear that they will be caught out by the risks they have taken. In their rush to escape the consequence of greed, they may start a chain reaction, an avalanche of panic that carries away the innocent along with the guilty.
