Determined on getting a rise in money supply (5)
I believe the answer is:
notes
'determined on getting a rise in money supply' is the definition.
I can't judge whether this defines the answer.
'determined on getting a rise' is the wordplay.
'determined' becomes 'set' (synonyms).
'getting a rise' is a reversal indicator (in a down clue, letters go up).
'set'+'on'='seton'
'seton' reversed gives 'NOTES'.
Can you help me to learn more?
(Other definitions for notes that I've seen before include "Observes; short comments" , "Marks on a stave" , "output from musicians" , "Short missives" , "fivers?" .)
