Former money manager Ann Barnhardt, who in November of 2011 made the decision to cease operations of her brokerage firm and return funds to her customers citing “systemic” problems within the entire financial industry, has issued a new warning about the stability of US banks and the safety of individual deposit accounts.

The warning, stemming from a recent federal appeals court ruling surrounding customer funds lost during the 2007 collapse of Chicago futures broker Sentinel, indicates that individuals who lose deposited funds because a financial institution improperly manages that money, even if those funds are supposed to be “segregated” from other operations of the firm, are essentially left with no recourse if the firm goes belly-up. According to the court, a misallocation of those customer funds, “is not, on its own, sufficient to rule as a matter of law that Sentinel acted ‘with actual intent to hinder, delay, or defraud’ its customers.”
