Unauthorised disclosure causing a loss in liquid assets (7)
I believe the answer is:
leakage
'loss in liquid assets' is the definition.
'leakage' can be an answer for 'loss' (I have seen 'Loss of fluid' mean 'leakage' so perhaps 'loss' could also mean 'leakage'). I am not certain of the 'in liquid assets' bit.
'unauthorised disclosure causing a' is the wordplay.
I cannot quite see how this works, but
'disclosure' could be 'leak' (leak is a kind of disclosure) and 'leak' is found in the answer.
'a' is present in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for leakage that I've seen before include "Escape of liquid/gas" , "Liquid lost" , "Unwanted discharge of fluid" , "Something that has escaped, like gas or secret" , "Fluid which escapes" .)
