As the nation prepares to mark the tenth anniversary of the Brexit referendum, a comprehensive review of the economic landscape reveals a stark reality: the decision to leave the European Union has inflicted significant financial damage on both households and businesses. While forecasters may have misjudged the immediacy of a recession, the long-term repercussions are undeniable, with the UK economy now notably smaller than it would have been had it remained within the EU.
The Economic Reality Post-Brexit
Contrary to initial Treasury forecasts, which predicted an immediate recession following Brexit, the economy did not collapse as some had feared. Instead, unforeseen global challenges such as the Covid-19 pandemic and geopolitical conflicts have obscured the true economic impact of leaving the EU. Nevertheless, experts assert that the long-term forecasts were correct; the UK is now facing a significant economic downturn characterised by reduced trade, stagnating business investment, and lower productivity growth.
Charlie Bean, a former deputy governor of the Bank of England, reflects on the misleading nature of the Treasury’s early warnings, stating, “Osborne has a lot to answer for… In hindsight, we had the vote and the world didn’t fall off the cliff immediately.” Yet, he acknowledges that the broader economic assessments were more accurate, concluding, “We’re poorer than we otherwise would have been.”
Currency Fluctuations and Trade Impacts
The immediate aftermath of the referendum saw the pound plummet, with a historic drop of approximately 10% on the morning after the vote. This depreciation has persisted, with the pound currently trading at $1.34 and €1.15, far below its pre-referendum values of around $1.50 and €1.31, respectively. The weaker currency was anticipated to benefit exporters by making UK goods cheaper abroad; however, uncertainty surrounding trade has hindered this potential advantage.
Despite the EU remaining the UK’s largest trading partner, with exports valued at £385 billion in 2025, the imposition of trade barriers has led to a decline in goods exports compared to other G7 nations. Service exports, however, have fared better, largely due to the nature of the UK-EU Trade and Cooperation Agreement, which imposes more friction on goods than on services.
Investment Stagnation and Productivity Challenges
One of the most significant consequences of Brexit has been a notable decrease in business investment, estimated to be around 18% lower than it would have been had the UK remained in the EU. This investment freeze can be attributed to prolonged political uncertainty and a lack of clarity regarding the future trading relationship. John Springford from the Centre for European Reform notes that the investment strike initiated in 2016 persisted until 2021-22, causing a detrimental impact on productivity.
As businesses hesitated to invest in equipment and infrastructure, productivity has suffered, with estimates suggesting it is now up to 4% lower than it would have been under a remain scenario. This stagnation points to a broader issue of economic malaise rather than a straightforward recession.
Employment Trends and Public Sentiment
While the unemployment rate in the UK initially dipped following the Brexit vote, this trend masked deeper underlying issues. Real wage growth has stagnated, and the country experienced the slowest recovery in workforce participation among G7 nations following the lifting of pandemic restrictions, with rising economic inactivity due to health issues.
The demographic most affected by these changes has been young people, with over a million 16- to 24-year-olds now classified as NEET (not in education, employment, or training), the highest level since 2013.
Public support for the Brexit decision has waned significantly, with recent YouGov polling indicating that 70% of Britons favour a closer relationship with the EU. Furthermore, a majority now believes that rejoining the EU would be beneficial, particularly among Labour and Green voters.
Migration Patterns and Economic Implications
In the wake of Brexit, net migration levels surged, reaching nearly one million in the year leading up to June 2023. This influx, driven by various factors including the war in Ukraine and changes to migration rules, has resulted in a shift in the composition of migrants, with nearly 90% arriving from outside the EU.
However, net migration from EU countries has decreased, exacerbating labour shortages in key sectors such as construction, hospitality, and manufacturing. Recent data indicates a further decline in net migration to 171,000, as stricter controls implemented by both Conservative and Labour governments take effect.
Why it Matters
The economic ramifications of Brexit are profound and far-reaching, impacting not only the nation’s financial health but also the livelihoods of millions. As the UK grapples with the consequences of its decision, the data paints a troubling picture of stagnation, diminished growth, and a population increasingly disillusioned with the promise of sovereignty and prosperity. Understanding these trends is vital for policymakers as they navigate the complex landscape of post-Brexit Britain, where the challenge now lies in reversing the economic damage and fostering a more robust, inclusive economy for the future.
