The effects of Brexit will reduce workers' real wages in the years ahead, according to new research.

A study, which came from the Resolution Foundation, said leaving the EU has reduced how open and competitive Britain’s economy is.

The report, in collaboration with the LSE, said the immediate impact of the referendum result has been clear, with a “depreciation-driven inflation spike” increasing the cost of living for households, and seeing business investment falling.

It is estimated that labour productivity will be reduced by 1.3% by the end of the decade by the changes in trading rules alone, contributing to weaker wage growth, with real pay set to be £470 per worker lower each year, on average, than it would otherwise have been.

The report added that the North East is expected to be hit hardest by Brexit as its firms are particularly reliant on exports to the EU.

Sophie Hale, principal economist at the Resolution Foundation, said: “Brexit represents the biggest change to Britain’s economic relationship with the rest of the world in half a century.

“This has led many to predict that it would cause a particularly big fall in exports to the EU, and fundamentally reshape Britain’s economy towards more manufacturing.

“The first of these has not come to pass, and the second looks unlikely to do so. Instead, Brexit has had a more diffuse impact by reducing the UK’s competitiveness and openness to trade with a wider range of countries. This will ultimately reduce productivity, and workers’ real wages too.

“Some sectors – including fisheries – still face significant change to come in the years ahead, but the overall services-led nature of the UK economy will remain largely unaffected.”

The UK has not seen a large relative decline in its exports to the EU that many predicted, although imports from the EU have fallen more swiftly than those from the rest of the world.

The report said Britain has experienced a decline of 8% in trade openness – trade as a share of economic output – since 2019, losing market share across three of its largest non-EU goods import markets in 2021, the US, Canada and Japan.
