Can a U.S. bank decline to process an international wire transfer?

Interesting questions, so here is what might/might-not be possible.

You bank could refuse to send a wire if...

• International (Banking) Wires is something they just don't do
• The country you wish to send it to, is on the Embargo List
• The name appears on the OFAC list (Sender &/or Receiver)
• They do not have a direct or indirect banking relationship to send a wire to the country you are asking for.
• You (as the account holder) have a Risk &/or Compliance issue with the bank.

Other than these reasons (I'm sure there might be more), your bank cannot refuse you are service if it is being offered.
