The UK Govt is planning for a recession.
Stopping long term gilt sales means speculators cannot successfully bet against interest rates.
OK, so this blocks speculators from profiting off the nation's incoherent policy since the war. And civil servants are heading off those they are jealous of, by front running an expected or planned recession. Woeful. Very much plandemic style.
But it also means the price of everything will be impossible to discover, making matters worse than any speculator could and a swift recovery impossible.
