I am looking at the Advisory Opinion from CFPB to go with Reg B about Special Purpose Credit Programs. When it is discussing "for-profit organizations" is it referring to banks and that they must include a written plan that establishes and administers a SPCP under Reg B? I just stumbled upon this and so I am trying to determine applicability and is it something that banks should be doing and I'm behind?

If you have identified a need and have the time, energy, resources and competent legal assistance in developing such a program under the guidance - go for it. There are probably only a handful of such programs.

I just wanted to determine if "for profit organization" meant banks and if "must" meant requirement for all, that is all I wanted to check on. I'm assuming that "must" does not mean "regulatory required" then.

Yes - a bank is a "for profit organization" and the "must" relates to "if" you have a program.
