US regulators have sought explanation from Deutsche Bank AG about its “bad bank” proposal and its impact on US operations at the loss-making German lender, the Financial Times reported on Monday.

Officials at the US Federal Reserve are concerned on learning about Deutsche Bank’s strategy and have sought further details of the plan, which is part of the lender’s move away from investment banking, FT reported, citing sources.

The Fed did not immediately respond to a Reuters request for comment on the matter. Deutsche Bank reiterated an earlier statement without directly commenting on the FT report.

“As we said at the AGM on May 23, Deutsche Bank is working on measures to accelerate its transformation so as to improve its sustainable profitability. We will update all stakeholders if and when required,” Deutsche Bank said in a statement.

Reuters reported earlier this month that Deutsche Bank was planning to overhaul its trading operations by creating a so-called “bad bank” to hold tens of billions of euros of non-core assets.

The overhaul would also include shrinking or shutting equity and rates trading businesses outside of Europe, a source had told Reuters.

The bank also reportedly faces probe over its alleged failure to comply with laws meant to stop money laundering and other matters. The investigation involves problematic transactions, some of which are linked to US President Donald Trump’s son-in-law and senior adviser, Jared Kushner.

A Deutsche Bank spokesperson said last week: “We remain committed to cooperating with authorised investigations.”
