or the us dollar becomes worthless?
It's not a tether problem and it's hard to describe it as a risk from tether exposure because in this case they will do their job exemplarily - they will maintain a 1:1 ratio to the dollar - what they promise. But in the event that the dollar falls to zero, the question arises - who owns the tether reserves and the profits from their investment. The risk of losses is on our side, so at least part of the profits should be on our side too, but this is probably not the case. I am writing about this because Tether's balance sheet apparently contains around 2% of bitcoin and >5% of non debt assets that will not go to zero with dollar.
But here we are talking about unlikely cases in which tether "behaviour' will be the least of our problems.
About
their investment portfolio (
if its not faked). It is set relatively safely, as according to their report, 85% is cash or cash substitutes (which in my opinion is enough to never have problems with liquidity.) Why? it is said that 30% of bitcoins are lost. someone died and didn't hand over the keys, someone lost the keys, someone regularly leaves dust on various wallets. I think it's the same with tether. Great proof of this is the busd marketcap, which needed as much as 10 months to drop by 90% after it was announced that busd was going out of business. Tether is twice as old, so the number of lost tokens is probably twice as high. I know it sounds strange, but even if the rest of investments goes to zero, i think 80% in cash is enough to be 100% backed, because during the 8 years of tether's existence, people have been "burning tokens" on a daily basis.
But looking deeper, what "Cash Equivalents" is. They are mostly U.S. Treasury Bills that expire after 4 weeks, 8 weeks, 13 weeks, 17 weeks, 26 weeks, or 52 weeks. So because they have a short expiry period, they are not that susceptible to rate changes. Its not a 20 year bond that can dump 50% in price due to rising interest rates creating temporary paper losses
if they don't lie in their reports, their wallet seems to be safe enough that tether will never have problems maintaining the $1 exchange rate. And here's the big if and the biggest risk. If they don't lie...
Another big risk may be a massive attack by regulators and freezing of funds or them running with our money.
