I'm firmly in the camp that says, "The bank does not issue Phase II exemptions from currency transaction reporting" is a perfectly adequate and acceptable policy. (If your bank does not make loans on deepwater ships your loan policy probably does not address how such a loan should be structured. It's probable that no one even expects your policy to say you don't make loans on deepwater ships if you don't do actually do it.)
"Policies" that merely recite the requirements of a regulation are not policies...
