Quote from gnome:
how often have we heard of an FCM going bankrupt or someone embezzling funds to the detriment of segregated funds? I have not heard of any, so perhaps we should not be overly concerned.
Gnome,
Refco, L.L.C., the regulated futures brokerage (not the parent holding company or any other unregulated entity), back in the 1990s, embezzled well in excess of $100 million from segregated customer funds deposited in futures accounts. The CFTC found, in the 1990s, that Refco had repeatedly, on an almost daily basis, misused those funds to pay debts. Refco consented to the CFTC findings, without either admitting or denying wrongdoing, and was fined in excess of a million dollars. Refco was able to return the embezzled funds, because it was also able to cover its debts and to avoid bankruptcy.
So there is a precedent for embezzlement from segregated customer funds deposited with a clearing broker.
Also, it is likely that the only motivation powerful enough to cause such embezzlement was the need to avoid bankruptcy, and that Refco would have gone bankrupt if it had not embezzled those funds and temporarily used them to cover debts until other resources could be procured.
Also, a more recent example of embezzlement is provided by the victim Jim Rogers, who paid hundreds of millions of dollars of other people's money over to Refco, for deposit into segregated customer fund accounts, but instead, Refco effectively embezzled the funds, by depositing them into non-segregated accounts, with the result that the money has disappeared in the bankruptcy of Refco's associated entities.
The main flaw in your thinking is the idea that you can extrapolate from past worst case events, to establish that no substantial future risk exists. This is the type of mistake that led to Victor Neiderhoffer's two spectacular bankruptcies. Nothing has a precedent until it has happened for the first time. If you were never hit by a car, would it be reasonable to say that you will cross the street wearing a blindfold, because past experience indicates no substantial risk that you will be hit? No, you would reason that people get hit by cars all the time, so that you shouldn't act like a fool. You should similarly reason that men wearing expensive clothing suffer huge trading losses, go bankrupt, steal, defraud, and/or embezzle all the time, so that you shouldn't act like a fool.
