Deutsche Bank pegs its derivatives exposure at about $22 billion — and faces challenges in shedding those assets
Deutsche Bank created over the years a whopping $53.5 trillion (€48 trillion) book of derivatives contracts that it now is seeking to unload, but experts say getting rid of those assets is no easy task.
If all goes as planned, Deutsche Bank pegs its own exposure to its derivatives book at around $22.3 billion (€20 billion), according to recent estimates viewed by MarketWatch.
