Yes sterling is a sovereign currency but it’s value related to other currency’s varies, in 2008 before the crash it was 1.60 euros, before Brexit 1.30. Dropped as low as 1.09, now around 1.18 euros per £1 that’s how confidence in the UK affects sterling.
In the 2008 crash the Bank of England printed a lot of cash which caused the drop in Sterling, now that we have a Brexit deal (in theory) it will continue to recover somewhat. After that the market will judge the benefits or otherwise of any trade deals.
Maizie commented that the Tories have borrowed a lot in recent years, as an alternative to raising taxes - despite so called austerity.
NO
The demand for better services has caused them to borrow more, it’s easy to say it has been spent badly, would any one like to suggest who should get less. Raising taxes means there is less to spend on goods and services, those with most cash spend most and with so many indirect taxes ( VAT, Rates, Insurance, Cars, Fuel ) the net gain is very small. A lot has also been spent on infrastructure, renewables, railways and other large projects
Our current borrowing of around 90% of GDP is manageable.
Total U.K. assets are around £7 trillion we are borrowing £2 trillion, less than 30% of assets. We need to work harder but it’s not a problem the U.K. is solvent.
