How about the trial of UBS rogue trader Kweku Adoboli, the man who racked up $2.3bn in losses before anyone noticed (in fact, no-one appeared to really understand what was going on until Adoboli sent in his explanatory email) ? Nope, it's not that.

Nope, not that either.
Yep, the winner of the 2012 Biggest Banking PR Disaster goes to......
