Multinational group set trap in foreign currency derivative (10)
I believe the answer is:
unoriginal
'derivative' is the definition.
(similar in meaning)
'multinational group set trap in foreign currency' is the wordplay.
'multinational group set' becomes 'uno' (I can't justify this - if you can you should give a lot more credence to this answer).
'trap' becomes 'gin' (gin trap is a kind of animal trap).
'in' means one lot of letters goes inside another.
'foreign currency' becomes 'rial' (currency of Iran).
'gin' going inside 'rial' is 'riginal'.
'uno'+'riginal'='UNORIGINAL'
Can you help me to learn more?
(Other definitions for unoriginal that I've seen before include "poorly copied" , "lacking novelty" , "second-hand" , "stock" .)
