These charts are in the Office for Budget Responsibility forecasts that support the budget:
Interesting that bank rate is going up by much less than the sum Sunak referred to in the speech, and maybe later.
But the really interesting figure is on unwinding quantitative easing. Apparently, the economy is going to grow so much that it will be able to absorb more than £200 billion of quantitative easing reversal, which we know will take money out of the economy, reduce share prices, reduce confidence, force up interest rates and reduce real demand in the economy. none of which is reflected anywhere else in the forecasts made.
If you can believe that you will believe anything. I do not. This is yet more magical thinking.
