it is a "false negative hit" on the assumption you are really not that person on the adverse list. they have the right to suspend your TA but they would have reached out to you to seek clarification and for you to provide corrobrative evidence to prove you are not that person.
they suspend your TA is highly likely you did not respond to their outreach.
check with your trader who will definitely know what's going on.
I only know about it when i see my trading limit becomes $0 so i called my broker to find out then he says the credit department suspended my account becos they found my NAME on world wide search list
KNS la.. just becos my name same as some criminal then suspect me ???? sibei suay...
They search by name, they shd try to match the the NRIC too ma.. same name as criminal = kana suspected as criminal???
Next time some rapist name same as mine, dun tell me they going to suspect me again ?
