"We have proven on several occasions that we have been willing to cooperate closely with the authorities when needed — and authorities even have confirmed that. We will now continue in this spirit and as soon as we have new facts we will let you know," he added.
The Panama Papers scandal refers to a leak of millions of documents to the media by Panama-based law firm Mossack Fonseca in 2016. It triggered a global scandal after showing how the rich and powerful allegedly used offshore companies to evade taxes.
The papers accused several banks of breaching money laundering laws, including Swedish lenders Nordea and Handelsbanken. Both of these banks, however, were fined for these violations in 2015 and faced no further punishment after the Panama Papers were leaked to media the following year.
After years of losses, many investors have lost faith with Deutsche Bank.
Since 2015, the lender — which once had ambitions of competing on equal terms with Wall Street's banking giants — has endured a failed stress test in the U.S., several attempts to restructure, a leadership shake-up and a ratings downgrade.
Shares of the bank have tumbled almost 50 percent this year.
Correction: This story has been updated to reflect that Nordea and Handelsbanken received no additional fines as a result of the Panama Papers.
