Maybe wanting fare controlled by US bank (8)
I believe the answer is:
underfed
'maybe wanting fare' is the definition.
(fare can mean food)
'controlled by us bank' is the wordplay.
I cannot quite see how this works, but
'bank' could be 'fed' (nickname for the US Federal Reserve) and 'fed' is present in the answer.
'controlled by' could be 'under' (as in working 'under' a supervisor or manager) and 'under' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for underfed that I've seen before include "Too thin?" , "in a starved condition" , "Malnourished" , "Not having enough to eat" , "deprived of basic need" .)
