USDN is unpegged and below $0.70 [1] I don't believe they have a chance of recovery.
USDD dipped under $0.97 (the "official peg") both yesterday and today [2]. The reserves are being poured in to keep it propped up till confidence returns. Hmmmmm...
UST (Luna/Terra) is, as is well known, finally stable ;)
In the famous thread that brought down FTX, CZ accused SBF of trying to crash Tether with a paltry $250M. While I don't see how that could be, CZ knows much more than me about what is really propping up Tether, and that is a scary thought.
And now Circle is under pressure. OK, they are big, and somewhat audited, so they probably can hold up unless a LOT of customers wanted out.
Of course, if any of these exchanges or stablecoins were honest, they would have 100% of customer's funds available or close to available, and a run wouldn't be a risk. But, let's not kid ourselves - No one in this space is honest.
I can totally imagine a crash of USDN leading to a run and crash of USDD, than a bigger run on Binance and Tether. I wonder which of those two has a larger hole?
I also wonder whether a crash of a $20bn fund could cause less scrutiny on SBF? And what would happen to BTC without Tether's magical beans to prop it up?
