The 30 year bond was at it's highest point since 2007 right before the global financial crisis exploded.
Just over 2 weeks ago the US treasury had announced their plans and objectives for he next period and part of that included a 2 billion bond buyback. Buybacks started in 2024, the debt was so high that there was a loss of confidence in the markets. The buyback program was put in place to stabilize the markets. then a new POTUS came in and started tariffs and then a war and the bond markets went berserk so Bessent and the treasury significantly increased buyback programs. So beginning of august they announced the new program for the period, and literally just over 2 weeks later per a Yahoo Finance story, Bessent "Cried uncle" on the bond market and doubled the amount to 4 billion. THere's discussion of even increasing that.
It's NOT some trivial thing, the more of this they do the higher the risk of increasing inflation. Kevin Warsh per the article was basically just thrown a grenade by Bessent to try and manage the fed, hold inflation in check and eveythng they had planned just changed because of Bessent and of course Trump.
