Exclusive: MF Global mixed funds, transferred abroad
MF Global took futures segregated money and put it into the account for customer securities, essentially mixing futures and securities that were both owned by customers, said an official familiar with the matter.
Until now, it was believed that only customer futures accounts were affected.
The source also told Reuters that MF Global had been using customer funds for "several days if not weeks" rather than just a few days before the firm collapsed.
Regulators had previously thought the firm was using customer funds on the Thursday and Friday before it filed for bankruptcy on October 31.
CME Group, the Chicago exchange where MF Global traded, said it had reviewed the company's books a week before the bankruptcy and found no issues with the customer money.
If MF Global started improperly dipping into its customers' accounts long before the firm's collapse, the allegation would raise questions of why the regulators and auditors failed to spot such behavior.
Congress has already started asking questions about potential lapses in regulatory oversight of MF Global. The pressure on regulators would only increase if MF Global turns out to have misused customer funds over an extended period of time.
"Establishing the specifics of what happened is key to figuring out how the system failed and how to fix it going forward," Republican Senator Chuck Grassley of Iowa said in a statement on Thursday. "Congress will need to keep drilling down."
MF Global collapsed in late October after the firm was forced to reveal that it had made a $6.3 billion bet on European sovereign debt.
