This lesson opens with The New York Attorney General settlement with Tether and Bitfinex, February 2021.

What happened
Tether issued the largest dollar stablecoin, USDT, on the public representation that every token was backed one for one by dollars in reserve. In February 2021 the New York Attorney General concluded, after an investigation, that this had not been true at all times: reserves had at points fallen short, and Tether had lent reserves to its affiliated exchange Bitfinex to help cover a roughly 850 million dollar loss the exchange had suffered when funds at a payment processor were seized. The parties settled, paying an 18.5 million dollar penalty, agreeing to stop serving New York, and agreeing to publish reserve breakdowns for a period. The stablecoin did not collapse and holders were not directly wiped out, which is why the recorded loss is the penalty rather than a holder loss, but the case exposed the central problem of a stablecoin: the backing is a claim the issuer makes about itself, and for years there was no way for a holder to verify it. The claim said fully backed; the reality, the investigation found, was that at times it was not, and no one outside could tell the difference.
The decision point
A stablecoin's promise, that each token is backed and redeemable, is a claim the issuer makes about its own reserves, and a claim is only worth what can be verified. The Tether case exposed the gap: for years the representation was full backing, and there was no independent, timely way for a holder to check it, so the claim and the reality could diverge, and the investigation found they had. A compliance regime for stablecoins, of which the GENIUS Act is the US example, exists precisely to close that gap: not to manufacture trust by decree, but to convert the issuer's promise into a verifiable obligation, reserves of a defined quality, held in a defined way, disclosed and attested on a defined schedule, redemption on defined terms. The point of such a regime is that it makes the claim checkable, so that fully backed is not a marketing line but a legally required, independently verifiable state. So the way to read GENIUS, or any stablecoin rule, is to ask what it makes checkable that was previously only claimed, because the Tether case is what an unverifiable claim looks like when it turns out to be wrong, and the value of the regime is that it would not have stayed unverifiable.

What you will be able to answer

  • What did the NYAG find about Tether (2021)?
  • What is a stablecoin's backing before a regime makes it verifiable?
  • What does a stablecoin regime like GENIUS fundamentally do?
  • How to read any stablecoin rule?

Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.

Contested

The recorded loss is the 18.5 million dollar settlement penalty; holders were not directly wiped out and USDT did not collapse, so this is not a holder-loss figure. The roughly 850 million dollar affiliate loss that reserves were used to cover is a separate figure from the case. The lesson turns on the claim-versus-verifiable-reality gap, not on a holder loss.

This is one facet of Tether's regulatory history, distinct from the 2020 academic study and the October 2021 CFTC order; the lesson uses the New York finding that the full-backing claim was not true at all times. Tether has since changed its reserve composition and disclosures; the GENIUS Act's specific requirements should be read against its current text.
