@bijupsimon , this is just a gross look -- they actually would get detailed info on form 114 ( FBAR form -- which is per individual ). Additionally they get info. from the banks directly ---- but I have no idea if and whom actually looks at these mountains of data --- probably auto search and then human attention when the amounts are large. Note that these regs. are as a reaction to money laundering and funding of terrorists ( not us poor folks.
Glad we were able to help you
