Exactly how Tether is backed, or if it’s truly backed at all, has always been a mystery. For years a persistent group of critics has argued that, despite the company’s assurances, Tether Holdings doesn’t have enough assets to maintain the 1-to-1 exchange rate, meaning its coin is essentially a fraud. But in the crypto world, where joke coins with pictures of dogs can be worth billions of dollars and scammers periodically make fortunes with preposterous-sounding schemes, Tether seemed like just another curiosity.
Then, this year, Tether Holdings started putting out a huge amount of digital coins. There are now 69 billion Tethers in circulation, 48 billion of them issued this year. That means the company supposedly holds a corresponding $69 billion in real money to back the coins—an amount that would make it one of the 50 largest banks in the U.S., if it were a U.S. bank and not an unregulated offshore company.
