Resists American money (5)
I believe the answer is:
bucks
This clue is a double definition.
'resists' is the first definition.
(as in bucking a trend)
'american money' is the second definition.
(informal term for US dollars)
(Other definitions for bucks that I've seen before include "Goes against" , "English county (abbr) - deer" , "Male antelopes" , "overseas money" , "young men" .)
