I am wondering what MMTers here think about this article on removing money from the economy, and what it means for our previous notions of debt, and the role of government.
Can the Fed Unprint Money? - US News
I think too much is made of what the Fed has done since 2008. It was not a straightforward addition of dollars to the economy.
First, banks needed to recapitalize when their assets went down in value. So the Fed came in and bought up a bunch of weak assets at face value, exchanging dollars for MBSs and other such assets, a fairly even exchange of value. (In the Fed's hands, because they were able to hold them, those assets have been paying off.) Banks were then able to meet their capital requirements and keep on operating. It was an even exchange of value, but now the Fed held securities and the banks held dollars. Those transactions also increased the level of total reserves in the system; any net government spending increases total reserves.
As these securities mature, dollars flow back to the Fed, which not only takes dollars out of the economy, it also lowers total reserves. So some of this is already undoing itself. When the Fed sells those securities back in exchange for dollars, the same things happen; fewer dollars, and fewer reserves. If the Fed held all of these securities to maturity, all the dollars they spent (and a few more) would come back to them, extinguishing all of those liabilities. The net effect would be zero.
The increased deficit spending
did put net dollars into the economy, and of course it increased reserves, too. But, you (hopefully) get increased economic activity, which means taxes (and reserves) are going to flow back to the government.
Any flow of dollars back to the government "unprints" money. Most of this is taxation, and some of it is coming from securities held by the Fed. Nothing is permanent, but it's hard to claw back dollars once they get saved. You can't really tax China and Japan to claw back all of the dollars (bonds) they hold. On the other hand, they aren't doing any harm, sitting around unspent.
******************
We used to worry about the level of reserves in the system, drawing out the excess by exchanging reserves for interest-bearing bonds. QE showed that excess reserves weren't really a problem. They don't lead to more bank loans, so the money supply didn't "explode" like some economists worried about. MB grew a ton; M1 didn't follow. So really, not a heck of a lot happened. We bailed out the banks by moving some things around, we had some too-small stimulus spending, and that's it. Much of the "money printing" that everybody was worried about is sitting around as excess reserves, which are pretty harmless.
