...borrowing more money and minting new bonds, and committing to do that indefinitely in the future, while your central bank is literally trying to QT at the same time, is not "financial tightening". they've had to go back to QE temporarily to stop a liquidity crunch because the midwit running fiscal policy decided to run literally the opposite direction. and worse, he didn't just do it for a year, he committed indefinitely into the future to keep doing it and keep printing more bonds. so yeah the gilt got hella whipsawed but there's a reason it happened in england when all the other countries are tightening as well.
