Too wrapped up in financial solvency (4)
I believe the answer is:
also
'too' is the definition.
('also' can be a synonym of 'too')
'wrapped up in financial solvency' is the wordplay.
'wrapped up in' says the answer is hidden in the clue.
'ALSO' can be found hidden inside 'financial solvency'.
(Other definitions for also that I've seen before include "As well, in addition" , "To boot" , "into the bargain" , "Likewise" , "Furthermore" .)
