Brexit cost 6% of UK economy, Bank of England company data suggests
New analysis using Bank of England company data suggests Brexit has reduced the UK economy by 6%. The impact stems from post-referendum uncertainty and increased trade barriers.

A comprehensive study leveraging internal Bank of England company data indicates that Brexit has inflicted a 6% reduction on the UK economy. This significant economic blow is attributed to a combination of the initial shock and prolonged uncertainty following the referendum, alongside the subsequent imposition of trade barriers with the EU.
Imagine the UK economy is like a car. After Brexit, it's like the car lost 6% of its power. Some of this happened because everyone was unsure about the future, like a foggy road. The rest happened because it became harder for the car to get gas and parts from its neighbors, like building a fence around the gas station.
Analysis
Quantifying the Brexit Drag
The latest research, which draws upon internal Bank of England data from thousands of British companies, offers a stark quantitative assessment of Brexit's economic toll. By analyzing the Decision Maker Panel data—normally used to inform interest rate decisions—economists sought to model the UK's growth trajectory had it remained within the EU. The findings suggest a cumulative 6% hit to the economy over the decade following the referendum. This figure is derived from tracking firms' exposure to Brexit-related issues, their reported impacts, and changes in financial accounts, providing a granular view of the economic consequences.
The Dual Drivers of Economic Loss
The study identifies two primary drivers for this economic contraction. Approximately half of the estimated 6% loss is linked to the initial period of surprise and pervasive uncertainty that characterized the post-referendum landscape. The remaining half is attributed to the tangible rise in trade barriers that emerged after the UK officially left the EU's customs union and single market in 2021. This suggests a two-pronged impact: an immediate psychological and investment chill, followed by a more structural impediment to trade and economic activity.
Context and Caveats
While the study's methodology, which combines company-level data with five traditional analytical approaches, offers a novel perspective, it is not without its critics. Some economists argue that such models may not fully account for other significant global economic factors, such as the outperformance of US investment and tech sectors, or the European energy crisis. Furthermore, the Bank of England itself has issued a disclaimer stating that the views expressed in the paper do not necessarily represent its official stance. Despite these caveats, the research aligns with recent public statements from Bank of England officials, including Governor Andrew Bailey, who have increasingly acknowledged Brexit's negative impact on UK growth and productivity.
Key points
- Analysis of Bank of England company data suggests Brexit has reduced the UK economy by 6%.
- The economic impact is attributed to post-referendum uncertainty and rising trade barriers.
- The study used the Decision Maker Panel data, normally used for interest rate decisions.
- Critics argue the study may not fully account for other global economic factors.
- Bank of England officials have become more candid about Brexit's economic consequences.
The UK could potentially mitigate some of the negative impacts by forging new trade agreements and streamlining customs processes, as suggested by upcoming meetings between UK and EU officials. A focus on domestic innovation and strategic investment could also help offset the challenges posed by increased trade friction.
The persistent trade barriers and the ongoing uncertainty surrounding the UK's future economic relationships could continue to suppress growth and investment. Without significant policy interventions or a shift in global economic conditions, the UK economy may struggle to regain its pre-Brexit growth trajectory.
