Belief in financial standing (6)
I believe the answer is:
credit
'belief' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "Add (an amount) to an account" , "Direct (anag) - tick" , "Positive bank balance" , "Time given to pay for goods" , "entry in cashbook" .)
