The U.S. Commodity Futures Trading Commission said the bank was unable to report swap data for multiple asset classes for five days after the outage, and that its efforts to restore the services exacerbated existing problems and created new ones.

Some of these problems still persist, affecting market data made available to the public, and impeding the CFTC's ability to evaluate systemic risk in swaps markets, the regulator said.

The German bank's shortfalls reflected its failure to have adequate business continuity and disaster recovery plans in place, and violated a September 2015 CFTC order intended to prevent such shortfalls, the regulator added.

"Deutsche Bank's repeated violations warrant the intervention of a court-appointed monitor," CFTC Enforcement director Aitan Goelman said in a statement. The regulator said Deutsche Bank cooperated in the matter.

In a separate statement, Deutsche Bank said it understood the CFTC's concerns, and is "committed to meeting all regulatory requirements."
