Bloomberg reports that Zubrow was Chief Risk Officer from November 2007 until January, as bank personnel were evaluating changes to the computer-based mathematical models used to measure the potential for trading losses. The changes, which took effect in mid-January, made risks in the firm’s chief investment office look smaller than they were, fueling losses that reached $5.8bn as of June.
In the meantime, The New York Times reports that Irene Tse — who headed up the North American arm of the chief investment office, the powerful but previously little known unit at the center of the trading mishap — is leaving to start her own hedge fund.
Ms. Tse, meanwhile, joined the bank in early 2011 from hedge fund Duquesne Capital Management to take over as head of the North American trading desk.
And The Wall Street Journal speculates that former JPMorgan investment banking head Jes Staley will probably move on soon. He is thought to have come close to becoming CEO over at Barclays, but came up short over fears that investors might not take too kindly to another investment banker taking the helm.

'As a former regulator I think we do need to slow down a little bit instead of rushing up to all those fancy derivatives'.
