As the 10th anniversary of the Brexit referendum approaches, a comprehensive analysis illustrates that the decision to leave the European Union has led to significant economic repercussions for the UK. While the immediate recession many anticipated did not materialise, the long-term effects have left households and businesses worse off. Experts agree that the UK’s economic landscape has been reshaped, resulting in reduced growth, rising costs, and a decline in trade.
The Pound’s Decline: A Lingering Impact
Following the Brexit vote on 23 June 2016, the value of the pound experienced dramatic fluctuations. Initially, the currency rallied as it appeared that the Leave campaign would concede defeat. However, as results began to favour leaving the EU, the pound plunged by 10%, marking its largest single-day fall ever. This depreciation has driven up import costs, contributing to a significant inflation shock that has affected public finances and household budgets across the nation.
Despite the potential advantages of a weaker pound for exporters—making UK goods more affordable for foreign buyers—uncertainty surrounding trade regulations has hampered this sector. A decade later, the pound remains below its pre-referendum value, now trading at approximately $1.34 and €1.15, compared to around $1.50 and €1.31, respectively. This situation has particularly strained British holidaymakers, who now face higher costs abroad.
Slower Growth and Investment Stagnation
The anticipated recession following the Brexit vote did not occur, primarily because the Treasury’s forecasts were based on a potential immediate no-deal departure, which did not take place. Instead, the UK endured a prolonged transition period that obscured some of the immediate impacts. However, the Office for Budget Responsibility estimates that the economy is set to face a 4% reduction in national income over a 15-year span.
Research from Stanford University’s Nick Bloom reveals that, as of now, UK GDP per capita is 6% to 8% lower than it would have been had the country remained in the EU. This is evident when comparing economic progress relative to 33 other advanced economies, where a clear divergence emerged post-2016. “The statistics are really clear: the UK has grown more slowly after Brexit than before,” Bloom noted, implying a direct correlation between the decision to leave and economic slowdown.
Trade Barriers and Their Consequences
Brexit has imposed new trade barriers that have negatively impacted goods exports, with the EU remaining the UK’s largest trading partner. In 2025, UK exports to the EU were valued at £385 billion, while imports totalled £474 billion. Since the conclusion of the EU transition period on 31 December 2020, UK goods exports have lagged behind those of other G7 nations.
Interestingly, service exports have fared better, largely due to the trade agreement negotiated under Boris Johnson, which introduced greater friction for goods than services. Businesses face more red tape and border delays, leading to reduced demand. Bloom likens this to a shop relocating to the outskirts of town: “You make it harder to get there and back, and not surprisingly there is less demand.”
Employment and Public Sentiment
Although unemployment initially fell to its lowest levels since the 1970s after the referendum, it later spiked due to the pandemic, masking deeper economic challenges. Wage growth has been lacklustre, with real wages showing minimal increases until recently. The UK has also lagged behind G7 counterparts in workforce recovery post-pandemic, with rising ill-health contributing to increased economic inactivity.
The youth demographic, particularly those aged 16 to 24, has suffered the most, with over a million classified as not in education, employment, or training—marking the highest levels since 2013. Bloom estimates that employment levels are 3% to 4% lower than they would have been under a remain scenario.
Public support for Brexit has diminished significantly since the narrow 52%-48% vote, with recent polls indicating that 70% of Britons favour closer ties with the EU without full re-entry into the bloc. Furthermore, more than half of respondents express support for rejoining the EU altogether.
Migration Trends Shift
Following Brexit, net migration to the UK surged to a record high of nearly one million in the year leading to June 2023, despite promises from the Leave campaign that migration would decrease. A considerable portion of these new arrivals has come from outside the EU, while net migration from EU countries has declined. Employers have struggled with staff shortages, particularly in sectors formerly reliant on EU workers, such as construction and hospitality.
However, recent measures have tightened migration controls, resulting in a drop to 171,000 last year. This shift has sparked debates about the balance between maintaining a robust economy and controlling immigration levels.
Why it Matters
The long-term economic implications of Brexit are profound, highlighting the challenges of navigating a new trading landscape and the uncertainties that have stifled growth and investment. As households grapple with higher costs of living and businesses contend with increased operational hurdles, the need for a clear and coherent strategy becomes crucial. The lessons from this decade of economic turbulence are essential for shaping future policies that can restore confidence and drive sustainable growth in the UK economy.
