How Brexit Has Altered the UK’s Economic Landscape Over a Decade

A decade after the Brexit vote, the UK's economic landscape has undergone significant changes, with long-term impacts on growth, trade, and household incomes.

The 10th anniversary of the Brexit referendum has brought into sharp focus the economic consequences of the UK’s decision to leave the European Union. While the immediate recession predicted by some economists did not materialize, the long-term effects have been profound.

The economy is smaller than it would have been, trade has suffered, and households are worse off.

Experts agree that the long-term forecasts were accurate: the UK’s economic growth has slowed, business investment has stalled, and productivity has declined.

The pound has not recovered to its pre-Brexit levels, and trade barriers have created friction for goods exports. These changes have had a ripple effect on the economy and the lives of ordinary people.

The Pound’s Decline and Its Impact

The value of the pound took a significant hit following the Brexit vote. Initially, the currency gained as Nigel Farage appeared ready to concede defeat, but as early leave victories became apparent, the pound plummeted by 10% in its biggest one-day fall. This collapse drove up the cost of importing goods, leading to an inflation shock that affected public finances and household budgets.

Exporters, who typically benefit from a weaker currency, failed to take advantage due to uncertainty in trade. A decade later, the pound has not returned to its pre-Brexit level, standing at $1.34 against the dollar and €1.15 against the euro. This has made holidays abroad more expensive for British travelers.

Slower Growth and Economic Stagnation

The UK’s economic growth has slowed since the Brexit vote. According to the Office for Budget Responsibility, the UK is on track to suffer a 4% hit to national income over a 15-year period. Analysis by Nick Bloom, a leading British economist at Stanford University, shows that UK GDP per head is between 6% and 8% lower than it would have been without Brexit.

The analysis shows that Britain tracked closely with other advanced economies until 2016, before a significant gap in output opened up. Bloom attributes this gap to Brexit, stating that there is no other obvious explanation for the slowdown.

Trade Barriers and Business Investment

Brexit introduced trade barriers that have hit goods exports hard. The EU remains the UK’s largest trading partner, but growth in UK goods exports has slowed relative to the G7. Service exports have performed more strongly, but exporters face more red tape and border delays.

Bloom compared the situation to a shop moving from the center of town to the outskirts, making it harder for customers to access. The uncertainty surrounding Brexit has also sapped business investment. Investment is estimated to be close to 18% lower than it would have been under remain, and productivity up to 4% lower.

John Springford of the Centre for European Reform noted that the investment strike started in 2016 and continued through to 2026-22. This has had an impact on productivity, as workers do not have the best equipment, and existing capital is deteriorating. Springford described Brexit as more a story of stagnation than of recession and rising unemployment.

Employment and Wage Growth

Unemployment in the UK fell after the Brexit referendum to among the lowest rates since the 1970s, before rising sharply during the pandemic. However, experts say this obscured underlying challenges. Wage growth has stagnated, with average real wages barely growing until picking up strength after the pandemic.

Research by the National Institute for Economic and Social Research estimated that UK GDP was reduced by 3.2% in 2026 as a result of Brexit, equating to a reduction in public revenues of about £3.3 billion for Scotland last year. Analysis by the LSE Centre of Economic Performance indicated that post-Brexit barriers on food imports pushed up average household food costs by £250 between December 2019 and March 2026.

The Europe minister Stephen Gethins stressed that Brexit has exacerbated cost-of-living pressures at a time when families can least afford it. He described Brexit as a particular tragedy for young people, removing the freedoms to live, learn, and work across the EU.
