MFGlobal has signed today chapter 11, which means: Bankruptcy. It is about 43 Milliard USD in total. Not much compare to Lehman Brothers, but still enough if you hang in it with some little money.
One of the big players for derivatives on Wall street.
They speculated with Greek Bonds and hounder'ts of millions of USD are missing in there accountings.
As it is a company, which does also the transaction between different market participants, they gave the guarantee that they not will use money from accounts of there customers. So far, this seems to be truth until at the moment ( Tuesday Morning 01.11.11 )
Even than: If you have an account with MFG, think about what you do with that account.
Update: They traded with customers accounts :

Update: All client accounts are frozen. Means, you not can transfer any money to an other broker until the liquidators give them free. What can be done is to request a payout of your funds to your private account or to your company account. Even than, this can take a while until the case is settled.
So what do we learn with that or what confirmation do we have again: Never ever give all your trading money to just one broker, even if he is very big.
