Newest blog post: Stablecoins, meet 3% interest rates

The global rise in interest rates is finally beginning to percolate into the stablecoin sector. One of the effects of this rise is that centralized stablecoins like USD Coin and Gemini Dollar, which by default pay 0% to holders, are introducing backdoor routes for paying interest to large customers. (See my tweets here and here).

In the case of USD Coin, Coinbase refers to interest as a "reward." Gemini calls it a "marketing incentive." But less face it: they're really just interest payments.

The links I provide are the only public evidence of stablecoins doling out interest, but you can be sure that behind closed doors, large issuers like Circle/Coinbase, Gemini, and others are offering their largest customers -- in particular exchanges like Binance and Kraken -- the same deals.

Stablecoin issuers are offering interest to select customers because of the inexorable pressure of competition. After hovering near 0% for much of the last decade (see chart above), interest rates have ramped up to 3% in just a few months. Issuers hold assets to back the stablecoins that they've put into circulation, and now these previously barren assets are yielding 3%. That means a literal payday for these issuers. In the first quarter of 2022, for instance, Circle (the issuer of USD Coin) collected $19 million in interest income after making just $7 million the quarter before. In the second quarter of 2022, interest income jumped to $81 million. I suspect the third quarter tally will come in well above $150 million.

However, if they don't share at least some of this juicy reward, issuers risk having their customers flee to alternatives that do offer interest, like Treasury bills or corporate deposit accounts. And then the amount of stablecoins in circulation will shrink, eating into issuers' revenues.

And thus, we get to a world where Gemini is promising incentives and Coinbase rewards.

Alas, while large stablecoin holders may be benefiting from this trend, small holders of stablecoins are being ignored. They don't get to share in these sweet flows of interest income. Even folks with old-school U.S. savings accounts are being paid 0.17%!

Small stablecoin holders need to unite. By working together through a StablecoinDAO, their bargaining power vis-a-vis the big stablecoin issuers improves. They may be able to negotiate the same interest payments from Circle and other issuers that large stablecoin customers are getting.

For a good example of strength in numbers, take a look at the phenomenon of high-interest savings ETFs in Canada. Corporate customers of Canadian banks get far better interest rates on chequing deposits than retail customers do. A high-interest savings ETF manager bridges this divide. They collect money from retail customers, invest the proceeds in banks at the corporate rate, and then share the superior return with thousands of retail ETF unit holders.
A StablecoinDAO would work along the same lines as a high-interest savings ETF. People would deposit their stablecoins -- USD Coin, Gemini Dollar, Binance USD, USDP, Tether, Dai -- into a smart contract. In return they'd get a new stablecoin called, say, UniteUSD, which would be redeemable on demand into any of the DAO's underlying stablecoins. UniteUSD itself would be useful. It could be used for purchases, deposited into smart contracts, or traded on decentralized exchanges and whatnot.

StablecoinDAO would have the authority to swap one underlying stablecoin out with a new one. That potential threat would give the DAO the necessary leverage to negotiate interest payments. "Hey Circle, if you don't pay us 1% then we're going to shift the DAO's holdings over to Binance USD, your competitor." As a nuclear option, the DAO could threaten to buy short-term government debt.

The interest that the DAO receives would be funneled back to UniteUSD holders.

In sum, that's how interest rates finally filter through to small stablecoin owners.
