Global banks faced a fresh scandal about dirty money on Monday as they sought to limit the fallout from a cache of leaked documents showing they transferred more than $2 trillion in suspect funds over nearly two decades. Britain-based HSBC Holdings Plc, Standard Chartered Plc and Barclays Plc, Germany's Deutsche Bank AG and Commerzbank AG, and U.S.-headquartered JPMorgan Chase & Co and Bank of New York Mellon Corp were among the lenders named in the report by the International Consortium of Investigative Journalists and based on leaked documents. The report was based on 2,100 leaked suspicious activity reports (SARs), covering transactions between 1999 and 2017, filed by banks and other financial firms with the U.S. Department of Treasury's Financial Crimes Enforcement Network (FinCEN). Banks are required to file an SAR whenever handling funds that cause grounds for suspicion of criminal activity. The reports revealed broader problems with the monitoring system at the heart of global policing of money laundering and other criminal activity. Investors worried about the potential fallout for global banks, many of which have faced hefty fines in the past for lapses in controls and spent billions of dollars to bolster compliance. It confirms what we already knew: that there are huge amounts of SARs being filed with relatively low numbers of cases brought through to prosecution," said Etelka Bogardi, a Hong Kong-based financial services partner at Norton Rose Fulbright. "It also brings out the point that managing financial crime risk goes beyond making SARs," Bogardi said.
