Financier on cocaine makes a chilly impression (4,5)

I believe the answer is:

snow angel

'a chilly impression' is the definition.
(impression made in snow)

'financier on cocaine' is the wordplay.
'financier' becomes 'angel' (angel can mean an investor).
'on' means one lot of letters go next to another.
'cocaine' becomes 'snow' (synonyms).
'angel' put after 'snow' is 'SNOW ANGEL'.

'makes' acts as a link.

I've seen this clue in The Guardian.
