Scott Sumner Agrees that MMT Policy Proposals Are Not Inflationary

By Scott Fullwiler
Scott Sumner sets out to debunk theories of the price level not based on a form of the quantity theory of money, and lumps MMT in with those approaches that “deny open market purchases are inflationary, because you are just exchanging one form of government debt for another.” While this is true, what’s interesting is that from within Sumner’s own paradigm, MMT-related proposals should not be inflationary. This is clear right off the bat when he lists his first “qualifier” or exception to the quantity theory:

  1. If the new base money is interest-bearing reserves, I fully agree that OMOs may not be inflationary.  That’s exchanging one type of debt for another.

And that is about all we need to hear. As we’ve said probably gazillions of times, you can’t have discretionary open market operations beyond that which is consistent with the Fed achieving its federal funds rate target unless an interest-bearing alternative to reserve balances is offered. Traditionally, this has been Treasury securities issued by the Treasury or sold by the Fed. The only way to leave all the reserve balances circulating and achieve a positive interest rate target at the same time would be to pay interest on reserve balances.
For instance, later, when Sumner writes, “Now suppose that in 2007 the US monetized the entire net debt, exchanging $6 trillion in non-interest bearing base money for T-securities,” hopefully he realizes that this is not operationally possible without paying interest at the target rate on the excess reserve balances created unless the Fed wanted to have a zero-rate target.
