Answers Stablecoins & yield

Where does stablecoin yield come from?

Answer

Not from the stablecoin itself. A fiat-reserve stablecoin is a claim on reserves, and the return those reserves earn accrues to the issuer — under the GENIUS Act, no permitted payment stablecoin issuer "shall pay the holder of any payment stablecoin any form of interest or yield (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention of such payment stablecoin". So any advertised yield is being generated by something a third party does with the coins once you hand them over — lending them, market-making with them, or deploying them into a protocol. That activity, and the counterparty doing it, is what carries the risk. The stablecoin is not paying you.

Nuances and considerations

  • Follow the sentence “you earn X% on your stablecoins” to its subject. Someone is earning something, and the question is who, on what, and at whose risk. The reserve return belongs to the issuer. If a platform is passing you a return, the platform is generating it somewhere else and taking a spread.
  • The three usual mechanisms carry three different risks. Lending the coins exposes you to the borrower and to whatever collateral arrangement backs the loan. Market-making exposes you to inventory and venue risk. Deploying into a protocol exposes you to smart-contract failure and to the protocol’s own economics. “Yield” is the same word for all three and tells you nothing about which one you bought.
  • Retail lending programmes have been treated as securities offerings. In February 2022 the SEC charged a large retail crypto lending product with failing to register its offers and sales, found the interest-bearing accounts to be securities, and — in a first-of-its-kind action — also charged violations of the Investment Company Act; it settled for $100 million across the SEC and 32 states. A yield product is a product with a legal character, not a feature of the coin.
  • The prohibition is on the issuer, and the regime is not fully in force. Section 4(a)(11) binds permitted payment stablecoin issuers; the Act takes effect on the earlier of 18 January 2027 or 120 days after final implementing rules, which had not been issued a year after enactment. Expect the market’s structures to keep moving until then, and check the position on the date you are reading.
  • Custody is the question underneath the rate. While the coins are earning, who is holding them, under what terms, and where do you stand if that party fails? That is answered by the agreement, not by the yield figure.
  • Yield received is income. Income from digital assets is taxable for US federal purposes even where nothing was sold. This is general information rather than tax advice.

Deliberately no rate is quoted here. A rate is a marketing number that changes weekly; the mechanism generating it is the part worth understanding.
