It has already been an abysmal day for Germany's biggest lender: overnight Deutsche Bank plunged to fresh all time lows on speculation whether the German government would or wouldn't provide state aid to the bank (if needed), forcing the bank to state it does not need the funds at the same time as the government urged markets that "you can't compare" Deutsche Bank and that "other" bank, Lehman Brothers, although looking at the chart, one may beg to differ.

However, while DB stock closed at session lows, over 7% lower on the day, with its market cap of $16 billion now rapidly approaching the $14 billion litigation settlement demanded by the DOJ, the bad news did not stop there.

In a report issued an hour ago by Citigroup titled "Capital, Litigation & AT1 Coupon Risks", bank analyst Andrew Coombs says that Deutsche reported an end-June CET1 ratio of 11.2% pro-forma for the HXB stake sale, but still only targets c11% by end-2016 as further litigation charges are assumed, with management expecting to resolve four of the five major outstanding litigation cases this year. To this Citi says that it "struggles" to see how Deutsche Bank can reach the fully-loaded SREP requirement of 12.25% in the medium-term.
