I guess next time I should check the news for the current day's events before making an assumption about a dynamic topic.
Anyway, today's issue has passed -- back to trading at the peg. I suspect there were some stops and levered trades (especially at Kraken)hat were negatively impacted.
And I'm not suggesting it is wise to hold funds in USDTs. But for my purposes, transferring funds from one exchange to the next, I'm comfortable with using Tether -- even if there is some movement against the peg, as I don't hold it for more than a short period of time.
