Just a couple of thoughts. The FCEN is part of the Department of Treasury. It's very possible they have been a do-nothing office for last few years and suddenly because of fear of cancellation by the Doge they are starting to enforce the laws they were meant to do years ago and are becoming proactive. They want to keep their jobs and not have their Department canceled.
Another thought, if Thailand decides to side with BRICS, an organization/monetary initiative that Trump really hates, what is the possibility that he can order Banks, and maybe Social Security payouts, not to deal with countries, Banks, and currencies associated with BRICS. If he can't actually stop them or change who they do business with, he can certainly Step Up controls and security with organizations like FCEN, to make even simple, everyday Financial transactions very cumbersome and nearly impossible. That's something to mull over for the future.
