I attached my link to my original post. I didn't pull it out of thin air. From the link:
"Many experts say that the Libor scandal has eroded public trust in the marketplace. Indeed, securities broker and investment bank Keefe, Bruyette & Woods estimated that the banks being investigated for Libor manipulation could end up paying $35 billion in private legal settlements—separate from any fines to regulators."
Also, from the same link:
"All told, global banks have paid over $9 billion in fines."
Would like to believe your claim of $400 billion. Can you provide a link? The LIBOR case has only been discussed on this board for a couple of weeks since Imbellish posted a video interview. Those with more information are most welcome to share their knowledge about this case.
