Glitch or quick intervention in US bond market

Notice especially the US 2 year bond yield spike, this move is captured in almost all trading websites and I’m reading that there might have been a quick intervention.

Surprising to see one of the extremely liquid markets showing these kinds of moves.

Will this freak high levels come for real? If yes markets will swing with volatility

I had some analysis of it

some one sold heavy quantities of 2 year bonds making it illiquid resullting lowering prices and greater yealds. it had lasted roughly 4 hours and later what i speculate FED crisis management kicked in and bought.

most probably this guy is BOJ or chinese central bank. and boy they had planned that day there was 4 expiries in USA options.
