There has definitely been a wall of silence around Gilts rising…
Whose 'wall of silence?'. It's on the BBC news and in the FT.
It's not the interest on gilts that has gone up, it's the 'yield', which is different. The government won't have to pay any extra interest on bonds currently in existence, just the interest rate they sold them with. So its costs won't be any more than usual unless the Treasury issues more gilts at a higher interest rate. Which, frankly, it would be very stupid to do.
The 'yield' is calculated on the bond prices on the secondary market. A £100 bond sold for £100 with a 4% interest rate will have a yield of £4 in interest, i.e 4%. If the bond sells at a lower price on the secondary market, say for £90, then the £4 interest received will represent a (slightly) higher return on your £90 than it would have done had you bought the bond at full price, £100. This will be a higher percentage of £90 than it would have been of £100.
It's taken me a long time to get my head round this.
The alarmist stories are being told because it is assumed that the government must get revenue from bond sales or tax. The third and obvious option isn't considered.
If there is no option but to issue more bonds the theory is that they must offer a higher interest rate on them to make them attractive to investors. That's where an increase in the cost of 'borrowing' would come from.
If the government needs more money it can 'borrow' directly from its own bank, the Bank of England. It doesn't have to 'borrow' via bonds and gilts.
BTW one of the reasons that bond prices are low on the secondary market is that the Bank of England, for some completely unfathomable reason, has been selling off the bonds that it b'ought' for QE. They've been flooding the market a bit. It was that, incidentally, that did for Liz Truss. Not her budget plans.
