The news agency's sources say that Deutsche Bank has applied to cooperate with authorities in their investigation under the leniency programmes of the European Union and in Switzerland, but that it did not mean the bank was admitting any guilt.
'The bank last year obtained the status of being a witness for the prosecution in the EU and in Switzerland', one source said.
'As a result of that, the bank could get a lighter penalty if a punishment is imposed', another said.
Reuters also reports that, according to its sources, Barclays plans to pull out of the rate-setting panel for interbank lending in the United Arab Emirates because of its involvement in the Libor scandal in Britain.
Barclays belongs to a panel of 12 banks that quote indicative interbank lending rates in UAE dirhams. The quotes are averaged to arrive at a daily range of Emirates Interbank Offered Rates (Eibor), which are used to price financial instruments in the Gulf's top financial centre.
