I tried to process the sentiment in that twitter thread but I'm still none the wiser. It just seems this is an entirely confected and purposeful market manipulation to enable nation states, primarily the US to wipe / restore its debt on more favourable terms when the existing debt bonds and treasury yields appear worthless as a long-term monetary instrument / protection.
I do agree, that the apparent free-market, appears dead if it can be up-ended at a whim by a single person / nation. What a colossal mess.
Too stronger dollar and the triffin dilemma is the issue.
What it's setting up for is rather than QE, which is the central bank have a certain rate and choose what to buy to yield curve control, where the central bank buy everything at a certain rate.
