Deutsche Bank's controls that aim to prevent money laundering have caught the attention of regulators on both sides of the Atlantic. "Of course, we will closely cooperate with the Prosecutor's office in Frankfurt, because to us, all of the suspicions to educate", he said.
BaFin said its critics had misunderstood the situation, and that supervisors and prosecutors played different roles.
He pointed a finger at the German financial regulator BaFin, which in January released a report finding no evidence of significant instances of money laundering at the banks identified in the Panama Papers.
On Thursday, as the raids were going on, the vice chairman of supervision for the U.S. Federal Reserve, Randal Quarles, met Deutsche Bank management for an unrelated and previously scheduled appointment at the bank's headquarters, a spokesman for the Fed said.
