I have no idea offhand. But i have another thread where i provided a link to the oecd site where you can select your country and it will tell you with what other countries they have automatic exchange agreements
If that is the case then i am wrong but switzerland has agreements with many countries given the historical nature of swiss bank accounts. As you did it is best to check oecd website for latest
So just for clarification, A Cuban resident can open Swiss account and no problem nor reporting happening seen that they no exchange relationship and isn't even on the list?
