I'm not sure about Kakuzu being a teller. However, if it was to take place you have to remember Kakuzu's nature. He would gladly accept your gold, but don't get upset when you have no interest and your gold is a little bit shorter than when you deposited.

It would only make sense for him to take some of your gold along with the interest. In return you get your gold (Well, the majority of it)

and the safety of knowing that your gold is in a safe and secure place being protected by Kakuzu.

Still want Kakuzu as your banker?
