It means selling into the 10 year. Which you would think there would be buying as a move to safety. If there is selling is that people not seeing USDT as safe? Are countries that hold USDT as the reserve currency of the world pissed and they are starting to dump?
You lose USD as the reserve asset then you get high intrest rates that smoke market and could indicate that we are losing the ability to print endless money without the massive ramifications.
It is one day. Could be a blip on the radar and probably is. I see USD as the reserve asset until BTC is. Tether and stable coins have already become and will become an enormous USDT buyer to help maintain that reserve status for another 25 to 50 years. Just because people on the street know usd and want usd not rubles or other FIAT.
Eventually people will stop wanting any fiat and a constant drain on their wealth. That won't be until BTCs NGU technology is entrenched in every humans mind and the volatility drops closer and closer to USD levels.
