Chain banking is a pervasive, but seldom
studied form of banking organization.
Resembling in some respects other forms of
multi-office banking—such as holding company
or branch banking—it is, however,
largely unrestricted by current federal and
state banking regulations. Although a bank
involved in a chain banking situation reports
individually to its primary bank regulatory
authority, there is usually little publicized
recognition of its affiliation with a chain.
