Monetary Cease Fire

It's 2 am, the fear is gone
I'm still sitting here, the gun still warm
Maybe my connection is tired of taking chances
--Golden Earring

Last week the Fed made a final bond purchase before shutting down its fourth round of QE operations. 

During the most recent round of QE, which was instigated during the CV19 panic, the Fed has added an additional $5 trillion to its balance sheet--on top of the roughly $4 trillion from the previous QE junkets.

As shown above, QE programs by the Fed and other central banks around the world have lit a fire under asset prices. Any attempt to unwind QE balance sheet assets has led to lower prices.

This begs questions about the durability of this monetary cease fire. What will the Fed do with those $trillions on its balance sheet? And how long will it be until QE5 fires up?
