The cooperation of a former Julius Baer banker with U.S. officials in a money-laundering probe has sparked the Swiss private bank to launch its own probe.

Matthias Krull, Julius Baer's former «onboarding superstar» in Latin America, is accused of helping Venezuelan businessmen launder money.

The private banker helped rinse as much as $1.2 billion of funds from state-backed oil firm PDVSA, as finews.asia reported last week. German-born Krull was snapped up by officials in July in Miami, and agreed to cooperate with U.S. justice officials. 

Julius Baer, for whom Krull worked for 11 years, is starting its own investigation into the alleged dealings, CEO  Bernhard Hodler said at a conference in Zurich. Swiss financial regulator Finma had already been probing the bank over PDVSA.

PEP Clients

In his cooperation, the 44-year-old Krull admitted that he acquired Venezuelan clients including Francisco Convit Guruceaga, who stands accused of money-laundering. Krull, who spent part of his school years in Caracas, enjoyed excellent relationships with Venezuela's economic elite and so-called PEPs, or «politically exposed persons».

The banker and several of his team defected for Genevan private bank Gonet in June. Krull never began at the rival Swiss bank.
