Is there a maximum amount that a bank to bank transfer will allow?

That would be up to the individual bank, but there is no rule that covers all bank that sets any sort of limit. Bank to bank transfers are pretty secure, so the receiving bank knows you have enough money in the sending bank to cover the transaction, so there usually isn't any sort of limit.





Keep in mind that if you transfer more than $10,000 in from a foreign country, customs and possibly the tax man are going to want to know about it.
