repo market?
gpt
when banks dont have anything great to do with cash they can park it with the gov for a short duration and earn interest. Right now the money in that market is 2.2T, that says that banks have a huge amount of money, but do not think theres anywhere good to put it at these prices. As prices decrease, or as economic conditions improve, that money will deplete. 

That money is the 'buffer' against true panic, which is when prices are falling and all available capital is deployed.
