Stock market meltdown has Republican invested in liquid asset (5)
I believe the answer is:
crash
'stock market meltdown' is the definition.
I can't judge whether this defines the answer.
'republican invested in liquid asset' is the wordplay.
'republican' becomes 'R' (abbreviation in US politics).
'invested in' is an insertion indicator.
'liquid asset' becomes 'cash' (I've seen this in another clue).
'r' placed into 'cash' is 'CRASH'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for crash that I've seen before include "Economic collapse" , "(Of shares) fall suddenly by a great amount" , "Car accident" , "Bang" , "Dramatic fall" .)
