Brexit Nears Its 10th Anniversary: UK Lags Behind Competitors In Growth

Economic analyses reveal that, despite almost 10 years having passed since the Brexit referendum, GDP per capita in the UK has grown up to 10% less than similarly anticipated. According to the "Decision Maker Panel" research initiative conducted by King's College London, the UK economy has deviated significantly from its pre-2016 trajectory following Brexit. Investment, productivity, and global power have increased slowly and steadily. The research report states, "By the beginning of 2025, the UK economy is projected to be approximately 8% larger than Brexit based on macroeconomic data, and 6% larger based on microeconomic data at the firm level."

 Researchers point to a long period in which political events and trade relations have frozen or delayed decisions that normally trigger growth. Instead of investing and hiring, companies have waited for the next announcement or change in trade conditions. Investment plans were suspended nationwide, and executives seized their time on risk assessments and Brexit preparations instead of launching new product rollouts or expanding operations. The study states, “Investment is estimated to be 12–18% lower, employment 3–4% lower, and productivity 3–4% lower; these are the levels the UK would have been if it hadn’t decided to leave the EU.” The damage was not evenly distributed. Businesses most deeply integrated into European supply chains (including many of the UK’s most productive exporters) felt the hardest hit, and sectors historically driving national growth weakened.

Researchers describe the UK’s departure from the EU as a “reverse trade reform,” reversing trade barriers traditionally expected to be removed in a globalized economy. Yet, trade flows did not collapse immediately after the referendum. For several years, the UK operated under existing rules, masking the ongoing, deeper change. The real turning point occurred after the Brexit Trade and Cooperation Agreement came into effect, as there was no significant impact before that. Over time, the UK's performance began to decline compared to its competitors. Growth slowed, living standards stagnated, and the country fell in economic rankings. Currently, it is estimated that the UK's GDP per capita is growing "6–10 percent less than other similar countries" and that the country is "in the top 10 percent" among developed economies.

The report warns that while initial estimates were correct in terms of direction, the period of uncertainty will last and how profoundly it will affect companies' decision-making processes. The researchers argue that what policymakers once saw as a "temporary adjustment" has transformed into a structural change in the economy that is still having an impact. When all the findings are combined, it appears that the UK's situation was shaped not by a single political event, but by years of misguided efforts, declining confidence, and weakening competitiveness. Despite the passage of time, the negative effects of Brexit are still showing no signs of diminishing.
