Quote from mokwit:
That could be the case, but if that is consumed then other clients funds would be used. the point I was making is that Clearing firm directors are not required to auction off their homes before they use your money o pay someone elses debt.
My guess is that the origin of it is that big locals wanted an option payoff profile so they devised this structure because it allowed them to solicit client funds to the amount of what they thought their worst possible losses would be and they would thus be covereed by someone elses money. A cursory inspection of the BS the exchange puts out might lead you to believe that client funds are protected by the full faith and credit of the whatever, and your funds are safe, NO my firend.
