Earlier quoted context omitted.
Tether is atleast supported with real world assets (USD/bonds etc). The amount and quality of the assets might be debatable but it can't go into a death spiral to zero like Luna and UST.
Only 3.87% of Tether was backed by dollars: https://siliconangle.com/2021/05/13/tether-releases-reserve-... So it could drop pretty far.
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.
