Share in Germany’s biggest bank, Deutsche Bank tumbled after a surprise fourth-quarter loss due to a cluster of issues including restructing, legal issues and a drop in debt trading revenues. <br /><br />The bank has warned of a challenging year ahead, not least because of persistent legal and regulatory wrangles which have dogged the bank for the last year. <br /><br />Deutsche Bank has had to fork out 528 million euros in litigation costs in the quarter, bringing the bill for fines and settlements for the year to 2.5 billion euros. <br /><br />Deutsche was fined $1.9 billion, or 1.4 billion Euros in December by the U.S. Federal Housing Finance Agency. <br /><br />It was also fined 725 million euros by European Union antitrust regulators for rigging benchmark interest rates.
