'paris zone' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'correct financier' is the wordplay.
'correct' becomes 'right' (right can mean correct).
'financier' becomes 'bank' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'right'+'bank'='RIGHT-BANK'

'provides' is the link.
