Leaving Peru trade in confusion (9)
I believe the answer is:
departure
'leaving' is the definition.
(I know that leaving can be written as departure)
'peru trade in confusion' is the wordplay.
'in confusion' indicates an anagram.
'peru'+'trade'='perutrade'
'perutrade' with letters rearranged gives 'DEPARTURE'.
(Other definitions for departure that I've seen before include "Exit" , "change of direction" , "shift" , "Lucky" , "outbound journey?" .)
