The Commodity Futures Trading Commission (CFTC) staked a claim on Friday as a potential creditor of failed commodities brokerage MF Global Inc, in a sign that it may charge the bankrupt firm and seek monetary sanctions, Reuters reported on Friday. The CFTC said that it filed a claim as a "general creditor" in order to "preserve all possible options" to recover funds related to its investigation. The CFTC and other government agencies have been examining whether MF Global misused customer funds in its final, chaotic days. The commission said that it took action so that if its investigation results in an enforcement action, it could pursue a restitution award.
