Arab country offloading Middle East currency (3)
I believe the answer is:
yen
'currency' is the definition.
(Japanese currency)
'arab country offloading middle east' is the wordplay.
'arab country' becomes 'yemen' (Yemen is a Middle Eastern country).
'offloading' is a deletion indicator.
'middle east' becomes 'me' (abbreviation for Middle East).
'yemen' with 'me' taken away is 'YEN'.
(Other definitions for yen that I've seen before include "Intense desire for Japanese money" , "Have a longing for Japanese money?" , "Currency of Japan" , "Japenese currency" , "Strong desire" .)
