I cannot remember which agency I was looking at, but FDIC or OCC exam guide had examples of high risk accounts, such as pawn shops, check cashing places.. etc.
Please let me know which agency. Thank you.

oCheck cashing or money transmitting businesses
oAuto, vessels, bus or aircraft dealerships or chartering
oAny businesses that have more than 50% of their revenue from sales of lottery tickets or money orders
oGaming of any kind
oInvestment advisory or investment Banking services
oReal Estate closing, brokerage, or title insurance
oFarm equipment or mobile home businesses
oAccountants, doctors, lawyers, pawn brokers or auctioneers
oTrade Union activities

In the OCC's Comptrollers BSA Handbook they give a listing of high risk entities.

Hope this helps!

How are you determining whether your business customers are in a high risk industry? Do you give them a list and ask them if they're on it? Do you have your new account reps ask them what industry they're in, and then have the new account rep determine whether that's a match to the high risk industry? Do you have a back office/centralized process in lieu of a front-line process?

You should be determining the nature of business conducted by your new customers at the time a relationship is established. Compare type of business to OCC's list (which is comparable to international high risk entity standards) and monitor according to your policy.
