Stay and use the money going round the States (7)
I believe the answer is:
suspend
'stay' is the definition.
(I've seen this before)
'use the money going round the states' is the wordplay.
'use the money' becomes 'spend' (I can't justify this - if you can you should give a lot more credence to this answer).
'going round' indicates putting letters inside (some letters go around others).
'the states' becomes 'US' (abbreviation for the United States).
'spend' placed around 'us' is 'SUSPEND'.
'and' is the link.
Can you help me to learn more?
(Other definitions for suspend that I've seen before include "Hang, defer" , "Temporarily render inoperative" , "Temporarily debar" , "Bring to a temporary halt" , "Hang freely" .)
