Hefty charge recalled by banks (5)
I believe the answer is:
beefy
'hefty' is the definition.
(thesaurus)
'charge recalled by banks' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge).
'recalled' says the letters should be written in reverse.
'banks' is an insertion indicator (bank can mean to surround or border).
'fee' reversed gives 'eef'.
'eef' going within 'by' is 'BEEFY'.
(Other definitions for beefy that I've seen before include "Muscularly well-developed" , "Athletic and muscular (non-vegetarian?)" , "Brawny" , "like some bully?" , "Colloquially muscular" .)
