Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services. Corporate alliances are intermediaries between credit unions and financial markets.
