IN ENGLISH for those among us who don't speak finance:
Deutsche Bank, a large multinational that has been in a great deal of trouble, is being fined fourteen billion dollars (more than the GDP of El Salvador as Quartz so colorfully puts it) for being shady as fuck in their dealings around mortgage-backed securities, a variety of "valueless thing banks sell for shit-tons of money" that tanked the economy in 2007 a la The Big Short.
Deutsche Bank, which has already paid out some $11b in fines, doesn't have that kind of money. Their balance sheet says they have about $5.5b to pay fines. BNP Parabas, another big-ass bank, has an analytical department that figures DB only set aside about $2b to deal with these particular fines, which makes things more exciting.
A lot of DB's money is tied up in CoCo Bonds, which pay a great yield because they transfer a lot of risk to the bond-holder. In short, the bank is borrowing your money and paying a really great rate of interest because if they get in trouble, you no longer own a loan, you own stock in a failing bank.
Right now, those bonds are trading like shit because the market sees this as a sign that those bonds are about to hand grenade themselves into nothing.
Devil's Advocacy: Yves Smith over at Naked Capitalism thinks this is all theatre:
...but it does reflect one of the recurrent themes of finance in 2016, namely that the US is fully willing to fuck over foreign institutions in the name of the USA.
