For a special edition of Geoforum on socio-spatial exclusion, credit u
nions unexpectedly have it all-a financial institution currently at th
e margins of both the economy and society generally, rigid demarcation
of boundaries, exclusionary territories and tendencies, power relatio
ns, and most excitingly the possibility for a geography of financial i
nclusion. Whilst most analyses have effectively treated credit unions
as unsocial, uncontested spaces of purely economic considerations, thi
s paper enters into the interrelational, and social space of the credi
t union study group. In so doing, it illustrates two interesting parad
oxes at the heart of credit union operations. Firstly, it suggests a n
umber of potential exclusionary effects recent deregulatory legislatio
n has on the demarcation of common bond boundaries. Secondly, it illus
trates how common bond boundary construction initiates a purification
of financial space, but argues that the act of boundary formation itse
lf is ultimately exclusionary in nature. Awareness of such issues on t
he part of the credit union development community of Kingston Upon Hul
l is-highlighted through recent changes in the city's overall credit u
nion development strategy. (C) 1998 Elsevier Science Ltd. All rights r
