[Harry Potter] What happened to all the money in Gingotts while London was under the occupation of Voldemort?

Once Voldemort and the other Death Eaters had occupied  (read: taken over by force) London, and all the magical districts and businesses that came with it  (MoM, Diagon Alley, etc.) what happened to everyone's bank account? 

I couldn't see it being below Voldemort to just say "Congratulations! Your life savings have now been heroically donated to the war effort. You will be handsomely compensated, in that your death will be swift and merciful."

I could particularly see this happening if they found out that a sizable amount of money in the bank belonged to one Mr. Harry Potter, Public Enemy No. 1. 

Was the bank just like it's own sovereign nation, with the goblins as its sole residents? And were they willing to do business with anyone so long as they had the coin for it?

Gringotts operates like Swiss banks. They're sovereign and independent of the wizarding world, because neutrality is the crux of their business operation.
