FRANKFURT (Reuters) -The U.S. Securities and Exchange Commission is investigating Deutsche Bank (DE:DBKGn)'s asset manager DWS over how it used sustainable investing criteria to manage its assets, two people with knowledge of the matter said on Thursday.
The news, first reported by the Wall Street Journal, sent DWS shares down sharply as trade opened, and they closed 13.6% lower.
The two people spoke to Reuters on condition of anonymity because they were not authorized to discuss ongoing investigations. DWS and Deutsche Bank declined to comment on the investigation.
If it progresses, the case will be watched closely by the asset management industry.
Fund managers have rapidly amassed billions of dollars of assets that are meant to have an environmental or social profile, but is facing growing scrutiny over how firms define and apply environmental, social and governance (ESG) standards.
The SEC investigation follows a report earlier this month, also by the Journal, citing the former head of sustainability at DWS saying the investment firm overstated how it used sustainable investing criteria to manage investments.
The former manager, who could not immediately be reached for comment, left DWS earlier this year after less than a year in the job.
DWS, in response to the former manager's previous comments, said in a statement Thursday evening that "we firmly reject the allegations".
An SEC spokesperson said: "The SEC does not comment on the existence or nonexistence of a possible investigation."
The Journal, citing unnamed sources, also reported that federal prosecutors in the New York City borough of Brooklyn were looking into the matter.
A spokesperson for the U.S. Department of Justice (DOJ) declined to comment on the Journal's report.
Deutsche Bank, which has been expanding its sustainable financing business, has also been trying to restore its image in Washington amid several investigations into its dealings with former President Donald Trump, a long-standing client.
DWS is the second German fund manager under U.S. regulatory scrutiny.
Allianz (DE:ALVG) is also facing DOJ and SEC investigations over losses last year at its fund division, Allianz Global Investors.
