Is it really that much different, the Government can borrow money and pay interest via a bond issued currently borrowing is high close to 100% of annual GDP. Those bonds represent security against the value of UK infrastructure, our credit is good so interest rates are low.
I don't think you have noticed that interest rates are not low, they have been steadily increased over the past few months and look set to be increased again. All because the BoE thinks this will control inflation, when in actual fact, inflation is being exacerbated by higher interest rates because it isn't inflation caused by too much money in the economy, it's inflation caused by external price rises (just like the '70s when OPEC price increases caused inflation).
When 14million people in the UK are in poverty there clearly isn't too much money in the economy to be taken out by increasing interest rates. The only result will be to drive more people into poverty as the cost of borrowing (that £1,3 trillion in mortgages) increases inflation.
The alternative is QE where the BoE buys those bonds on the open market and creates money to pay for them, they don’t need to pay interest but the bond has a life, when that ends cash has to be found to pay it back.
Bonds do pay interest, that's a key reason why people and institutions buy them. But they also buy them because they know that they are the safest investment available because the UK will not renege on the 'debt'. It won't renege because it can create the money for interest payments and repayments at term. It all boils down to trust in the currency.
But I'll point out, once again, that at least a third of the UK's 'borrowing' is money owed to itself. QE was achieved not only by the BoE buying bonds from the market, but also by the Treasury creating new bonds which were then 'bought' by the BoE. The BoE is owned by the state. So the 'debt' to GDP figure is misleading as the money the Government 'owes' to the BoE won't ever be repaid. You can't 'lend' to yourself...
Commercial Banking is separate and lends against the value of an asset, a house, or other property, the interest varies according to the risk. As has been pointed out previously it is “new” money, not limited but controlled by the BoE.
Commercial banks create new money under licence from the BoE. The BoE puts that money into the reserve account through which all bank transactions are carried out. For some unfathomable reason, the BoE pays interest on the reserve account, which makes their books look bad and just increases commercial bank profits. I really can't see the rationale behind this. And it certainly doesn't look like 'control' when the amounts transferred to the reserve account appear to be unlimited.
