Many CUs have cut outgoing international wire service this year, so it wouldn't be too surprising to see banks starting to discontinue service, too. Not particularly sure on reasoning. "Due to new Regulations and the inherent risk with International Wires, we will no longer be able to provide this service to our members."
What are CUs?
Do you mean credit unions?
Yes.
ETA: Story is.... allegedly... confirmed.
"UPDATE: Chase Bank confirmed to Infowars that all business account holders were being subjected to these new regulations. Given that even a relatively small grocery store or restaurant is likely to turnover more than $50k a month in cash payments, this appears to be part of a wider move to shut down businesses who mainly deal in cash. Chase told us customers would have to upgrade to much more expensive accounts to avoid the capital controls, meaning larger corporations will not be affected. The bottom line is that banks think your money is their money and will do everything in their power to prevent you from withdrawing it in large quantities."
