Hi Duke
That's a great video. The illustrations were brilliant. I only vaguely understand QE, and like, you I don't know how it gets reversed.

It's easy to explain how conventional QE gets reversed.
With QE, the CB buys lots of financial assets.
They could buy shares, but they tend to buy bonds.
They need to buy a lot, so they need to buy in a large, deep, liquid market.
Typically, then, they buy Govt bonds, as there is a very large market for these assets.
Sometimes, they buy high-grade corporate bonds, or bank bonds, or mortgage-backed bonds.
In the US, the Fed bought lots of Treasury bonds, but also Mortgage Backed Securities MBS issued by wholesale banks.
To reverse QE, simple sell the bonds back into the market.
