Bankers were fined roughly $110b for their misdeeds in the mortgage market during the run up to the financial crisis. You may not approve of the bank's actions during the run up, but I'm sure you wouldn't be happy to know that some $1.2b of the fines are could not be tracked down or are unaccounted for.
A huge chunk $49 billion of the funds are with the Treasury Department. The agency initially received $14.5 billion from settlements, though other government agencies, including $34 billion from Fannie Mae, Freddie Mac and other government-charted housing associations, later funneled money to the department. $45 billion was put aside for consumer relief. $10 billion was set aside to be used for housing-related federal agencies and to whistleblowers who called banks out. Some of the funds were also go back to the Treasury. $5.3 billion went to states, which appeared to use the money as they saw fit, including directing the money to pension plans which were hit hard by the fallout from mortgage-back securities. $447 million was given to the Justice Department, which had a role negotiating with banks. Some $1.2 billion could not be tracked down or is unaccounted.
