There is a failure to see the distinction between a genuine business failure and a scam. There is a need to ensure the safety and integrity of the markets. It is most important to ensure that brokers' liabilities are adequately covered through margins and securities. Once the integrity of the settlement system is ensured, the regulator can investigate whether there were any illegalities in trades and if these are found, the guilty should be suitably punished. Politicians or others not connected with the markets have little role to play in this and should leave the job to the market regulator.
Wild allegations lead to unnecessary rumours that erode the credibility of the markets.
This is surely not what we all want.
