| I was hoping that the OP would address a related idea that I find rather weird: it’s sometimes said that “this excess liquidity has to go somewhere” and that “the excess liquidity has gone into [housing/stocks/commodities/other asset class]”. But I don’t get this: It might seem plausible that if stock prices go up they absorb liquidity from the system. But (ignoring new stock issues / newly build houses) in every transaction there’s both a buyer and a seller. Sure, the buyer parts ways with cash when they buy a share, but that cash goes to the seller. So there should be just as much liquidity as before, just in different hands. If anything a rising stock or housing market should just put more excess liquidity into the system because it’s possible to borrow against those assets. What am I getting wrong? Or is this just an often repeated falsehood? |
You are correct when taking the view of the financial sector as a whole - every asset purchase merely swaps who has the cash and who has the asset. You're not getting much of anything wrong, merely missing a behavioral trait of many market participants: they desire a fixed ratio between their various financial assets. An extreme example of this is an index fund, which has a formulaic relationship between their book value and how much of what assets they own.
In essence, what happens is that cash gets dumped into the laps of various market participants, who then notice that they have "too much" cash. They then bid on various assets until there no longer is "too much" cash in the system for the total value of assets around.
