Yen -- yen! Making money (8)

I believe the answer is:

yearning

'yen' is the definition.
(I've seen this before)

'yen making money' is the wordplay.
'yen' becomes 'y'.
'making money' becomes 'earning' (I've seen this before).
'y'+'earning'='YEARNING'

(Other definitions for yearning that I've seen before include "Longing - desire" , "Intense longing" , "Feeing great desire" , "Unfulfilled desire or need" , "Hankering, longing" .)

I've seen this clue in The Telegraph.
