The debate about stablecoin regulation is at bottom part of a broader debate about regulatory classification of fintech payment service providers (PSPs). But it is, IMHO, wrong to reduce this debate to the question, "Is it a 'bank' or not?"


Posing the question that way implies that there are only two options: (1) Fintech PSPs aren't banks, and therefore shouldn't have to get stnd. bank charters or abide by the reg's that go w/ such to gain access to public settlement facilities. That's what many stablecoin fans say.

(2) fintech PSPs are banks; and therefore must be get bank charters and be subject to the same regulations ordinary banks must abide by. That's the answer offered by the STABLE Act

The second answer relies, not unreasonably, on the standard regulatory definition of a bank as a "deposit taking" institution. But IMHO it's that definition that's problematic, and that renders the conventional bank-nonbank dichotomy so.

For conventional banks aren't just "deposit taking institutions." They combine deposit taking with lending. It's this combined set of activities, not deposit taking per se, that (rightly or wrongly) supplies the rationale for many bank regulations, including deposit insurance.
Thread: This brief @PilkingtonPhil note on Gunnar Myrdal's _Monetary Equilibrium_ is indeed very good. That work (which helped earn Myrdal the Nobel he shared w/ Hayek) Some follow-up remarks here.


As Phil notes, Myrdal was a member of the Stockholm School, whose contributions to monetary theory built upon the work of Knut Wicksell, the school's founder. In By 1931, when _Monetary Equilibrium_ appeared, a (polite) rift had separated the school in two.

The rift began with a debate between Wicksell and David Davidson concerning the sort of price stability implied by a policy of keeping interest rates at their "natural" levels. Wicksell of course claimed that this would result in stable _output_ prices.

Davidson instead argued for a "productivity norm," with the stable factor prices, which would have the output price index move inversely with factor productivity.

Eli Heckscher and Gustav Cassel were among the more well-known Swedes who sided with Wicksell. Myrdal, in contrast, was , as did many those who sided with Davidson. (Hayek, by the way, also shared Davidson's opinion, as did many non-Swedes. See
