>Liquidity is the amount of cash in the system relative the size of the market for assets. All else equal, adding or removing is the same as adding or removing cash.
Citation needed there buddy. Like you're arguing that the Fed is hoovering up too much cash? Wouldn't QE be anti-liquidity since it's net result is more cash goes to the Fed and QT be pro-liquidity since the opposite happens?
On this earth, liquidity is about transaction velocity, and The Fed taking transactions off the table (by being a guaranteed buyer at every auction) makes non-Fed transactions happen at lower prices. The end.
Anyway, enjoy the end of this flamewar.
