Peru's new money (5)
I believe the answer is:
purse
'money' is the definition.
(a purse contains money)
'peru's new' is the wordplay.
'new' indicates an anagram.
'perus' with letters rearranged gives 'PURSE'.
(Other definitions for purse that I've seen before include "Small pouch for carrying money, mostly by women" , "Compress (lips)" , "Woman's wallet" , "Prize money - prepare to whistle" , "Winner's prize" .)
