Ten years after Britain voted to leave the European Union, Deutsche Bank has released a sweeping assessment of Brexit’s economic toll on the United Kingdom.
Using a synthetic control model, the bank compared the UK’s actual trajectory against a hypothetical “doppelganger” economy that remained inside the EU.
The analysis concluded that Brexit has left the UK economy roughly 4% smaller than it would otherwise have been under continued EU membership.
Employment has also taken a measurable hit, with the report estimating Brexit reduced jobs by around 2%, equivalent to approximately 685,000 positions lost relative to the counterfactual.
Consumer prices were found to be about 0.7% higher than they would have been had Britain remained in the EU, adding modest but persistent pressure on household budgets.
Much of the economic divergence only became visible after the pandemic and the implementation of the UK-EU Trade and Cooperation Agreement in 2021, as earlier years were cushioned by monetary stimulus, a weaker pound, higher immigration, and inventory stockpiling.
Business investment emerged as one of the weakest areas of performance over the decade, with prolonged uncertainty over future trading arrangements consistently weighing on corporate spending decisions.
Goods exports to the EU also underperformed many G7 peers, as newly erected trade barriers increased costs for British exporters competing in European markets.
The Deutsche Bank report did, however, identify meaningful areas where the UK has benefited from its departure, including greater regulatory flexibility, an independent trade policy, and a stronger position in artificial intelligence regulation and financial services.
Improvements in the UK’s current account balance and continued growth in services exports were also cited as positive developments stemming from the post-Brexit arrangement.
Looking ahead, Deutsche Bank estimated that targeted improvements to the existing UK-EU Trade and Cooperation Agreement could increase UK GDP by between 0.4% and 0.8% without requiring a return to deeper political integration with Brussels.
The report concluded that rebuilding closer economic ties with the EU remains politically challenging, with any broader reset likely requiring support from both UK voters and European policymakers before meaningful progress can be achieved.
