Advances behind shortfall - needing banks to negotiate (5)
I believe the answer is:
nears
'advances' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nears that I've seen before include "Moves towards" , "Approaches - snare (anag)" , "Moves closer to" , "Saner (anag.)" , "Draws closer to" .)
