Yep I have been told by multiple sources that the same things will be happening.
I have also seen letters sent out by UK and Commonwealth banks to their clients saying that they will close ALL accounts of any business which is NOT in compliance with the new US law.
Based on this development I believe the Treasury department has ALREADY issued warnings to banks and financial institutions that they must come into compliance immediately if they do not wish to face punitive actions taken against their US operations and subsidiaries.
Thats the only thing that would explain such a swift response from the banks.
