Like-minded collection of moneylenders? (8,5)

I believe the answer is:

interest group

'of moneylenders?' is the definition.
The definition suggests a singular noun which matches the answer.

'like-minded collection' is the wordplay.
'like-minded' becomes 'interest' (I am not sure about this - if you are sure you should believe this answer much more).
'collection' becomes 'group' (I've seen this in another clue).
'interest'+'group'='INTEREST GROUP'

(Another definition for interest group that I've seen is " Set working with a common aim".)

I've seen this clue in The Guardian.
