Empty talk in managing assets (3)

I believe the answer is:

gas

'empty talk' is the definition.
(I've seen this before)

'in managing assets' is the wordplay.
'in' says the answer is hidden in the clue.
'GAS' is hidden in the letters of 'managing assets'.

(Other definitions for gas that I've seen before include "chew the fat" , "Wind" , "Nitrogen maybe" , "Eg, oxygen" , "Chatter vapidly" .)

I've seen this clue in The Sun.
