Bank holding little cash of late (8)
I believe the answer is:
recently
'of late' is the definition.
(synonyms)
'bank holding little cash' is the wordplay.
'bank' becomes 'rely' (to bank on something is to rely on it).
'holding' indicates putting letters inside.
'little cash' becomes 'cent' (eg small amount of cash in US coinage).
'rely' placed around 'cent' is 'RECENTLY'.
(Other definitions for recently that I've seen before include "In the near past" , "Of late" , "Lately" , "Adverb meaning not long ago" , "Not so long since" .)
