As always, Matt Levine is shockingly informative: https://www.bloomberg.com/opinion/articles/2021-10-07/matt-l... Key quote: 1. You get a bunch of Bitcoins. 2. You slice them into junior and senior claims. 3. You sell the junior claims to people who want levered Bitcoin: people who want margin loans against their Bitcoins, etc., who want to gamble on Bitcoin without putting up too much cash. 4. You sell the senior cl…
If tranching were all Tether were doing, it would just be fraud. You can't sell a senior tranche on a pool of assets as a fully-backed security and call it a day. But whatever, Tether did that and more, nobody cared, we're on the next tier of the Narcissist's Prayer [1].
The new problem is we have circumstantial evidence that at least some of Tether's assets are Chinese developers' commercial paper. That's a risky asset. Even before Evergrande and Sinic defaulted, it was a speculative asset. (Now it's a distressed one.) If that's what we know they're in, how bad is the rest of their balance sheet? Tether claims to be over-collateralising their crypto-backed loans by 30%. An LTV of 77% will start losing money in a 25% crash. Bitcoin...does that a lot? For an asset they understand, they've set their risk limits woefully low. If that's what we know they're doing, how thin is the rest of their capital?
We're going to see a run on Tether. Not might. Statistically, the assets Tether holds will sometimes go down. Sometimes a lot. Most of the time, that will be fine. Some times, however, Tether will get a redemption at the same time. (Assets going down and investors redeeming things are correlated.) Most of the time, that will work out. Some times, however, Tether will need time to avoid their own selling driving down the asset's price. Most of the time, that will be fine. Some of the time, however, the person making the redemption request won't have that time. They'll blow up, and they'll blame Tether. This will prompt additional redemptions, which will force the aforementioned fire sale until, in all likelihood, Tether kills its domain and steals the money. (The last part is a novelty really only afforded by their setup.)
