Rite performed at bank (4)
I believe the answer is:
tier
'bank' is the definition.
(both can mean a row of similar things)
'rite performed' is the wordplay.
'performed' is an anagram indicator.
'rite' with letters rearranged gives 'TIER'.
'at' is the link.
(Other definitions for tier that I've seen before include "Row, level" , "Echelon" , "Wedding cake feature" , "Level within hierarchy" , "One of two or more rows" .)
