Most self-satisfied to suggest around a grand (8)

I believe the answer is:

smuggest

'most self-satisfied' is the definition.
('smug' can be a synonym of 'self-satisfied')

'suggest around a grand' is the wordplay.
'around' is an insertion indicator.
'a grand' becomes 'M' (synonyms).
'suggest' placed around 'm' is 'SMUGGEST'.

'to' is the link.

(Another definition for smuggest that I've seen is " Most superior".)

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