Criticise a financial centre’s greed (8)
I believe the answer is:
rapacity
'greed' is the definition.
(synonyms)
'criticise a financial centre's' is the wordplay.
'criticise' becomes 'rap' (I've seen this before).
'financial centre' becomes 'city'.
'rap'+'a'+'city'='RAPACITY'
(Other definitions for rapacity that I've seen before include "Predatory nature" , "Great greed and exploitation of others" , "Greed, the plundering of others" , "Voracious greed" , "Extreme greed and predatory quality" .)
