Key findings

The analysis finds that:

The OBR has handed the Chancellor the biggest downgrade to productivity forecasts since its creation in 2010.

On a ten-year rolling basis, productivity growth is set to fall to 0.1 per cent by the end of 2017, marking this as the worst decade for productivity growth since 1812 – when Napoleon was busy invading Russia.

As a result the economy is on course to be £42bn smaller in 2022, compared to the March 2017 forecast.

Faced with these grim economic forecasts driving projections for an extra £30bn of borrowing by 2021-22, the Chancellor has chosen to accept that public finance deterioration and increase it by a further £15bn. In doing so, he has all but abandoned his main fiscal objective (and manifesto aim) of reaching an absolute surplus by the middle of the decade.

The Foundation notes that:

If the Chancellor did decide to meet the Conservative Manifesto aim it would require a doubling of the pace of deficit reduction in the three years running up to 2025-26.

A slight pause in cuts to day to day departmental spending (per person) is set to take place in 2018-19. However, budgets are still set to be 16 per cent lower in 2022-23 than in 2010-11. In contrast, capital spending per person is set to exceed pre-crisis levels by the start of the next decade.

Looking at how the revised economic forecasts affect household incomes, the analysis finds that:

The current income squeeze is set to be longer (though shallower) than the post-crash squeeze, with real household disposable incomes set to fall for an unprecedented 19 successive quarters between 2015 and 2020.

Despite welcome but relatively small shifts on Universal Credit, tax and benefit policies announced since Summer Budget 2015 are set to put downward pressure on living standards and upward pressure on inequality. The poorest third of households are set for an average loss of £715 a year by the end of the parliament, while the richest third gain an average of £185.

The Foundation’s analysis of the measures making up the Chancellor’s welcome focus on housing finds that:
