Deutsche Bank has banned text messages on company-issued phones in an effort to improve compliance standards.
The functionality will be switched off this quarter, chief regulatory officer Sylvie Matherat and chief operating officer Kim Hammonds told staff in a memo on Friday, according to a person with knowledge of the matter.
Unlike emails, text messages can't be archived by the bank, said the person, who asked not to be identified discussing internal matters.
Deutsche Bank is working to improve compliance and clean up a reputation dented by a series of probes into its role in the sale of toxic debt, manipulation of interest-rate benchmarks and failure to prevent possible money laundering in Russia.
Chief Executive Officer John Cryan, who has made changing the culture at the bank a key pillar of his revamp, last month reached a US$7.2 billion (NZ$10b) agreement in principle with the Department of Justice to settle an investigation into the bank's sales of mortgage securities before the financial crisis.
Deutsche Bank has been slapped with more than $13.9 billion in fines and legal settlements since the start of 2008, according to data compiled by Bloomberg.
That includes a $3.1 billion penalty it agreed to pay in the preliminary settlement with the DOJ. It doesn't include $4.1 billion in relief to borrowers that the bank agreed to provide over at least five years.
In July 2012, the bank accidentally destroyed 482 tapes of telephone calls that were among recordings the UK Financial Conduct Authority had ordered the company to preserve, according to the regulator.
The bank's foot-dragging and evasions increased the fine it paid to the FCA by 101 million pounds (US$122 million) to a total of 227 million pounds, the FCA said in April 2015.
Deutsche Bank spokesman Tim-Oliver Ambrosius confirmed the decision and declined to comment further.
