Any customer that provides financial services, including check cashing, should be classified as an NBFI (customer subject to expanded examination overview).
Monitoring levels are up to the individual bank, but my opinion is we spend too much time treating MSBs as if they represent greater risks than a garden variety NBFI. Once a customer becomes an MSB what you can expect from them in terms of documentation, etc. becomes very clear and they get a federal regulator (IRS) they did not have before. In my opinion, they are easier to document and no more difficult to monitor than any other NBFI.
