Demand from current, reported growth (6)
I believe the answer is:
insist
'demand' is the definition.
(I've seen this in another clue)
'current reported growth' is the wordplay.
'current' becomes 'in' (I've seen this in other clues).
'reported' shows a homophone (sound like).
'growth' becomes 'cyst' (type of growth).
'cyst' sounds like 'sist'.
'in'+'sist'='INSIST'
'from' acts as a link.
(Other definitions for insist that I've seen before include "Be firm in demands" , "Maintain strongly" , "Demand forcefully" , "Put one's foot down" , "Press" .)
