"The Southwest border region is a high-risk area for money laundering activity, in part, because of a high volume of cash and cross-border transactions, according to bank representatives and others," the report said on Monday.
"These types of transactions may create challenges for Southwest border banks in complying with Bank Secrecy Act/anti-money laundering (BSA/AML) requirements because they can lead to more intensive account monitoring and investigation of suspicious activity," the report said.
The GAO found that, in 2016, bank branches in the Southwest border region filed two and a half times as many reports identifying potential money laundering or other suspicious activity, on average, as bank branches in other high-risk counties outside the region — 273 compared to 110.
