The next high risk customer to consider are money changers and money remitters, collectively known as Money Service Operators or MSOs. They need bank accounts to clear their customer's transactions and have an inherently high risk of being used for financial crime. A bank that clears payments and receipts for an MSO will know very little about the originators and beneficiaries of the transactions and must rely on the due diligence and controls of the MSO to mitigate the risk of transactions in dirty money. MSOs are not as strictly regulated as banks and brokers, and many do business with walk-in customers. Even if they do due diligence on remitters, they rarely do any due diligence on beneficiaries. The enhanced due diligence that a clearing bank conducts on an MSO is the critical factor in determining whether clearing services can be provided despite the risks. This is an expanding area of business for banks as non-bank third party payment processes such as Alipay take an ever larger share of the money transfer business. Don't forget that behind every digital wallet provider there is a clearing bank.
