Problem is the Suspicious Activities Report regulations were created in 1992, and $10,000 then is equal to $22,471 today.
Another way to put it is that a $10,000 threshold today would have been $4,500 in 1992.
If you are withdrawing $10,000 from your own account, it doesn’t trigger anything. It’s deposits that are tagged.
The real problem isn’t asking for $100 bills, it’s asking for more than $10,000 in cash. That will get you an automatic Suspicious Activities Report from the Bank to the DOJ.
The reporting requirement has been in effect since 1970. Per wiki =>
“The Bank Secrecy Act of 1970 (BSA) ~snip~ Specifically, the act requires financial institutions to keep records of cash purchases of negotiable instruments, file reports if the daily aggregate exceeds $10,000, and report suspicious activity that may signify money laundering, tax evasion, or other criminal activities.[2]
So the $10,000 today would have been about $1,200 in 1970.
