Remote, small bank? (7)
I believe the answer is:
slender
'remote' is the definition.
(I've seen this before)
'small bank?' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'bank?' becomes 'lender'.
's'+'lender'='SLENDER'
(Other definitions for slender that I've seen before include "Slight, slim" , "Gracefully thin and elegant" , "Ann Page's suitor" , "Barely sufficient (means)" , "Svelte" .)
