HSBC is facing potentially explosive allegations that South American drug cartels have used it to launder money, and that it systematically and deliberately failed to install the systems needed to catch illegal transactions.
The scale of United States authorities' investigations into HSBC has so far only been hinted at in
the bank's regulatory filings, but leaked documents show prosecutors are looking into a wide range of alleged failings.
In one instance, the bank allegedly failed to raise any red flags when Drug Enforcement Administration agents posing as drug dealers deposited millions of dollars in Paraguayan banks and then transferred money to accounts in the US through HSBC.
The bank also continues to do business with so-called icasas de cambioi in Mexico, local currency exchanges used to send money abroad, without any of the proper systems for spotting suspicious transactions, it is claimed.
The casas are often used by Mexico's vicious drug gangs, the DEA believes. Documents from an investigation by the US Attorney's office were reported yesterday by Reuters.
