Lucrative pacts and trades see wealth explode (10,5)

I believe the answer is:

sweetheart deals

I'm a little stuck... Click here to teach me more about this clue!

'lucrative pacts' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'trades see wealth explode' is the wordplay.
'explode' is an anagram indicator.
'trades'+'see'+'wealth'='tradesseewealth'
'tradesseewealth' with letters rearranged gives 'SWEETHEART DEALS'.

'and' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
