Deposits blocked by current accounts (7)
I believe the answer is:
stories
'accounts' is the definition.
('story' can be a synonym of 'account')
'deposits blocked by current' is the wordplay.
'deposits' becomes 'stores' (store is a kind of deposit).
'blocked by' means one lot of letters goes inside another (I've seen this in other clues).
'current' becomes 'i' (symbol for electric current).
'stores' placed around 'i' is 'STORIES'.
(Other definitions for stories that I've seen before include "See 12" , "Tales" , "House sections" , "See 21" , "Accounts" .)
