When the cost of ten year borrowing for the government hit 4,38% for a very brief spike in September 2022 Rachel Reeves claimed Liz Truss had crashed the economy as this would put up interest rates. At the same time as a budget which announced a bigger deficit the Bank of England was putting up base rate, threatening more rate rises, announced a huge sales programme of government bonds and watched as the pension funds geared bond investment plunged causing another big wave of selling. The Bank quickly reversed the bond market fall by buying up some bonds, The ten year rate was down to 3.1% by November. A change of Chancellor cut the deficit a bit.The Bank after the event agreed its actions were mainly responsible for a lower the bond market
The ten year rate is now 4.68%.No hint from the Chancellor she has crashed the economy or upped the mortgage rate. This time you cannot blame the Bank for much of the fall as it is easing short rates down and is not going to up its sales.Nor can you blame pension funds and LDI as those have been reined in. This is about the impact of the budget which increased borrowing, hit confidence and undermined the growth rate.
Now the Chancellor is in a bind. Interest charges will now be higher on state debt, so her leeway in hitting spending and borrowing targets has gone.If the economy stays slow growing the government will need more tax rises and or spending cuts. More austerity will keep growth low.
