Deutsche Bank has tried to curtail the behaviour of its traders in an attempt to clean up its tarnished image.
Germany’s biggest lender has warned its trading and investment bank staff to desist from Wolf of Wall Street type behaviour.
Colin Han, the co-head of Deutsche’s investment bank, issued a video to staff. In it he said: "It's not OK to brag or to be vulgar or indiscreet. That will have severe consequences on your career. I've run out patience on this."
He said "reputation is everything" and some staff were "still a long way from meeting" the bank's standards.
Deutsche Bank has been beset by a series of scandals. Last year it was fined a cool €725m for its involvement in the Libor rigging scandal, a key rate used to fix the cost of borrowing on mortgages, loans and derivatives worth more than £288 trillion globally.
The Wolf of Wall Street film will not have helped build any positive images for any financial institution. It charts the true story of stockbroker Jordan Belfort and cronies who racked in money by illegal means at the expense of many. The true-life background included fast cars and women, drugs and orgies.
“You may not realise it but right now, because of regulatory scrutiny, all your communications may be reviewed,” said Mr Han in the video. “This includes your emails, your conversations and your conduct.”
"Every communication which has the slightest chance of being interpreted as unprofessional must stop. Right now. Think carefully about what you say and how you say it. If you don't, it can have serious personal consequences for you," he said.
A recent investigation into foreign exchange market revealed evidence of the frequent use of inappropriate language and behaviour used in chat rooms, instant messages and emails at international banks.
