As the tenth anniversary of the Brexit vote approaches, a comprehensive analysis reveals that the decision to leave the European Union has had profound negative implications for the UK economy. While initial fears of an immediate recession did not materialise, a range of factors has contributed to a significant decline in economic performance, leaving households and businesses feeling the pressure. Experts agree that the long-term consequences of Brexit have resulted in a smaller economy, reduced trade, stagnant business investment, and increased financial strain on families.
The Pound’s Plummet: A Currency in Decline
The value of the pound has been a rollercoaster ride since the Brexit referendum on 23 June 2016. Initially, as Nigel Farage appeared to concede defeat, the pound briefly strengthened. However, as the results began to favour the Leave campaign, the currency experienced its largest one-day drop, plummeting by 10%. This decline has persisted, with the pound now trading at approximately $1.34 and €1.15, well below its pre-referendum values of around $1.50 and €1.31, respectively.
The depreciation of the pound has led to increased costs for imported goods, triggering inflation that has weighed heavily on public finances and household budgets. Exporters, who would typically benefit from a weaker currency, have struggled to capitalise on this situation due to ongoing uncertainty in trade relations.
Slowing Growth: The Economic Impact of Brexit
Despite early predictions of a Brexit-induced recession, the UK economy has not faced an immediate downturn. The Treasury’s forecasts, which suggested a swift exit without a deal, were overly pessimistic. Nevertheless, the Office for Budget Responsibility (OBR) estimates that the UK economy is set to shrink by around 4% over the next 15 years, largely as a result of Brexit.
Research conducted by Nick Bloom, a noted economist at Stanford University, indicates that UK GDP per capita is currently 6% to 8% lower than it would have been had the country remained in the EU. This slower growth trajectory has resulted in a widening gap between the UK and its peers, with the economic impact of Brexit becoming increasingly evident.
Trade Barriers and Business Investment
The introduction of trade barriers has significantly affected the UK’s goods exports, which remain heavily reliant on the EU—its largest trading partner. In 2025, UK exports to the EU totalled £385 billion, while imports reached £474 billion. Since the end of the transition period in December 2020, UK goods exports have seen slower growth compared to other G7 countries, in part due to the complexities introduced by the UK-EU trade agreement negotiated by Boris Johnson.
The uncertainty surrounding Brexit has also led to a notable decline in business investment. Estimates suggest investment levels are currently around 18% lower than they would have been under a remain scenario, with productivity 4% down. This reluctance to invest has resulted in inadequate resources for workers, exacerbating the economic stagnation.
Employment Challenges and Changing Public Sentiment
While the UK experienced a drop in unemployment rates following the Brexit vote, the pandemic has since reversed this trend. The rise in economic inactivity, particularly among young people, has raised alarms. Over a million individuals aged 16 to 24 are now classified as not in education, employment, or training, the highest figure since 2013.
Public support for Brexit has waned considerably since the referendum, with recent polling indicating that 70% of Britons favour a closer relationship with the EU without rejoining the bloc. Moreover, a majority now believe that rejoining the EU would be beneficial, reflecting a significant shift in sentiment as the realities of Brexit continue to unfold.
Migration Patterns Post-Brexit
Contrary to the promises made during the Leave campaign, net migration to the UK surged to nearly one million in the year leading up to June 2023. This increase has been influenced by various factors, including the war in Ukraine and the relaxation of Covid restrictions, alongside changes in migration rules post-Brexit. However, net migration from the EU has declined, creating staff shortages in key sectors like construction and hospitality.
Why it Matters
The economic landscape in the UK has been irrevocably altered by Brexit, with households and businesses grappling with the fallout. The combination of a weakened currency, sluggish growth, reduced trade, and rising unemployment paints a stark picture of the economic challenges that lie ahead. As public sentiment shifts and businesses adapt to the new reality, the long-term consequences of Brexit will continue to shape the UK’s economic future, highlighting the need for a strategic approach to mitigate these ongoing challenges.
