Earlier quoted context omitted.
Only 3.87% of Tether was backed by dollars: https://siliconangle.com/2021/05/13/tether-releases-reserve-... So it could drop pretty far.
> Only 3.87% of Tether was backed by dollars For comparison: Citibank had only 11.73% Tier 1 capital in their 2021 report: https://www.citigroup.com/citi/investor/quarterly/2021/ar20_... Couldn't find a breakout of their Tier 1, but it includes high-quality credit items as well, so actual dollars is well below 11.73%. So in other words: SiliconAngle.com is writing clickbait and doesn't understand modern banking.
Tether does not claim to be a fractional-reserve bank. They claim that 100% of the assets are backed by US dollar cash deposits. It's their entire raison d'etre. Except no one is enforcing it. It's not even remotely the same thing as a fractional-reserve bank.
