Raise credit in America, a small increase (6)

I believe the answer is:

uptick

'in america a small increase' is the definition.
(US term for an increase)

'raise credit' is the wordplay.
'raise' becomes 'up' (I've seen this in other clues).
'credit' becomes 'tick' (I've seen this before).
'up'+'tick'='UPTICK'

I've seen this clue in The Guardian.
