Public finances and public spending

The financial crisis and associated recession led to tax revenues falling as a share of national income and, to a greater extent, public spending rising as a share of national income. The extent to which spending exceeds revenues is the deficit, which in 2009–10 peaked at its largest level as a share of national income since at least the Second World War.

Since then the deficit has been reduced. In part this has been due to increases in tax revenues as a share of national income. But more significant have been the reductions in total spending. As a result the deficit in 2016–17 was at a similar level, relative to the size of the economy, to that recorded prior to the crisis in 2007–08, with both spending and receipts both slightly above their levels of a decade ago.

The latest forecasts imply revenues continuing to rise as a share of national income so that they reach their highest level since 1986–87. Current spending – that is public spending excluding investment spending – is forecast to continue to be reduced as a share of national income. If correct this implies revenues slightly exceeding current spending in 2018–19 (implying a current budget surplus), which would be the first time this had been achieved since 2001–02.

Investment spending (which represents the difference between total spending and current spending in the figure) is forecast to increase as a share of national income over the next five years, having been cut significantly during the first half of the 2010s.

By the end of the forecast horizon in 2021–22 total spending is forecast to be still running ahead of total receipts by 0.7% of national income (or £15 billion in 2017–18 terms). This suggests that further tax rises or spending cuts would need to be implemented if the deficit is to be eliminated by the end of the next parliament.
