Investigators carried out searches at Deutsche Bank and its subsidiary DWS as part of an investigation into investment fraud.
Prosecutors in Frankfurt raided the offices of both Deutsche Bank and its asset management subsidiary DWS on Tuesday as part of an investigation into so-called "greenwashing."
The searches related to allegations of financial institutions marketing investment products as more environmentally friendly than they really were.
What are the investigators looking into?
In a statement, Frankfurt prosecutors said investigators were carrying out raids "on suspicion of investment fraud."
Accusations of greenwashing against DWS have circulated for months, amid allegations that asset managers had overstated DWS's sustainability credentials on issues such as environmental protection and climate change.
Prosecutors say investigators have already found "sufficient indications" that ESG (environmental, social and governance) standards were applied only "in a minority of investments."
This, the prosecutors said, was contrary to information in DWS's "sales prospectus." There were no named suspects.
ESG products are an increasingly important asset class as financial institutions aim to trim portfolios in line with global climate targets.
The prosecutors said it was following accusations based on "statements made by a former DWS employee." The individual was said to have become a whistleblower for US securities regulators in 2021.
What do the businesses say?
Deutsche Bank confirmed that searches had taken place in relation to "greenwashing accusations" at DWS. The bank said in a statement that it would "work together with all relevant regulators and authorities."
It said that "the measures taken by the public prosecutor's office are directed against unknown persons in connection with greenwashing allegations made against DWS."
A spokesperson for DWS said it was "continuously and comprehensively" cooperating with the authorities.
