I believe part of the monitoring system of which you speak, is mainly cheques cashed over $10,000 is recorded. Also, some banks have been slack in this department ever since implementation and continue today whereas it is common for some companies to operate in this way. There is always a way to get around everything and it is not a compliance department of a banks responsibility to act on any transactions, they only inform, and sometimes they don,t inform, depnding on competence any other things.

There could be cheques cashed everyday for $9000 and it would never show up on the banking system. That could amount to millions in a year.
