Quite a lot has been written about the backing of stablecoins but Matt Levine uses the Tether use case to pose the question how much it matters for the kinds of activities that Tether is used for …
The point of a stablecoin is not mainly to be a secure claim on $1 of assets in a bank account. The point of a stablecoin is mainly “to grease the rails of the roughly $1 trillion cryptocurrency market,” by being the on-blockchain form of a dollar. We talk somewhat frequently about stablecoins that are openly backed by nothing but overcomplicated confidence in their own value; to be fair, we mostly talk about them when they are crashing to zero, but still. The thing that makes a stablecoin worth a dollar is primarily that big crypto investors treat it as being worth a dollar, that they use it as a medium of exchange and a form of collateral and value it at $1 for those uses. Being backed by $1.003 of dollar-denominated safe assets helps with that, but being backed by $0.98 of dollar-denominated assets might be good enough?
Matt draws no distinctions above but I don’t I think his argument is intended to apply to stablecoins that aim to challenge the traditional payment service providers (“payment stablecoins”) operating in the broader financial system. It does however pose an interesting question about how much stability crypto traders really require.
