The point of the tax cuts is to stimulate growth. If you want to stimulate growth then you put more money into the pocket of the greatest number of people, not more money into a small number of people, especially as they will not spend the money to stimulate the economy.
The tax cuts were to be funded by Govt borrowing, yet Friday’s statement has increased the cost of Govt borrowing. The run on the pound has to be stabilised by higher interest rates which means higher mortgage product costs, and for those ending their fixed terms, much higher mortgage payments wiping out any marginal tax benefits. The markets have factored in the higher interest rates and the BoE will be obliged to meet those expectations or create another run on the pound. None of this will stimulate growth. Indeed higher interests rates mean more costs to consumers which is the opposite of stimulating growth.
Not bad for Kwarteng’s first day in office, where the markets where obliged to put the new Chancellor on notice.
It also means Kwarteng will end up having to resign.
