Money expert (9)
I believe the answer is:
economist
'money expert' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for economist that I've seen before include "Money supply expert" , "Comes into (anag)" , "Expert in the management of a country's material resources" , "One versed in the management of a country's material resources" , "Financial expert" .)
