What Asian banks hold from half of factories etc (5)
I believe the answer is:
indus
'half of factories etc' is the definition.
I can't tell whether this definition defines the answer.
'what asian banks hold from' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for indus that I've seen before include "River of India/Pakistan" , "Main river of Pakistan" , "Pakistani river" , "River rising in Tibet" , "Long river of Asia" .)
