No. the BoE issues debt so in money terms they have just paid off some debt they owe. It's not what they have done, its why they did it.
- A pension fund will look at the amount of capital in your fund and offer a pension based on that, plus what they can earn with it going forward. Because no one has any faith in Britain, the value of future earnings have dropped to about zero. Assume you retired 5 years ago and your pension was calculated at £5k a month, that is based on the pot in 2017 plus future earnings. If the future earnings drop now to zero, there isn't enough cash to pay you, so the fund is bankrupt. People who retire this month will just get nothing!
- The Government takes out loans to borrow, these are 99% fixed rate. So changes in interest rates don't affect cash payments. But Government loans, like car loans, have a fixed life, usually about 5 years. If the Government has a loan of say £100m due for repayment, it will borrow, (new loan ), a £100m and use the proceeds to pay off the old loan. These new loans skyrocket in interest because again, no one has any faith where Britain will be in 5 years time.
By buying Governmnet loans the BoE forces the price of loans up, the yield goes down (interest/price= yield) and it stabilises those 2 markets. But they had to do it because of the incompetence of the Chancellor, and they've wasted £65bn, money they could have used for the NHS etc
