Bound to be short of cash? (8)
I believe the answer is:
strapped
I believe this clue is a double definition.
'bound' is the first definition.
(strapping is a kind of binding)
'be short of cash?' is the second definition.
(I've seen this before)
'to' acts as a link.
(Other definitions for strapped that I've seen before include "Without, or very short of, money" , "Needy - secured" , "Without, or very short of, cash" , "affected by shortage" , "beaten" .)
