Brexit’s Decade‑Long Economic Toll: How Britain Became Poorer

AI Summary
A decade after the EU referendum, charts show that Brexit has left the UK economy smaller, with a weaker pound, slower growth, and reduced investment. Experts estimate a 4% hit to national income and a 6‑8% lower GDP per head compared with a remain scenario.

Executive Summary of the Brexit Economic Review

The Guardian’s new chart pack confirms that voting to leave the EU has cost British households and businesses billions of pounds. While the immediate recession forecast by the Treasury never materialised, long‑term indicators – a depreciated pound, slower growth, weaker trade and stagnant wages – point to a substantial economic drag.

Charting the Pound’s Collapse and the Inflation Shock

On 23 June 2016 the pound plunged 10% in a single day, falling from around $1.50 and €1.31 to its lowest post‑vote levels. Ten years on the currency sits at roughly $1.34 and €1.15, keeping import costs high and feeding an inflation spike that strained public finances and household budgets.

Quantifying the GDP Gap and Trade Losses

  • Office for Budget Responsibility (OBR) projects a 4% hit to national income over a 15‑year horizon.
  • Research by Nick Bloom and the US National Bureau of Economic Research finds UK GDP per head is 6‑8% lower than it would have been without Brexit.
  • Since the end of the transition period (31 Dec 2020), goods‑export growth has lagged the G7, while services have performed better, reflecting new border frictions.

Broader Consequences for Investment, Employment and Public Sentiment

  • Business investment is estimated to be ~18% lower than in a remain scenario, dragging productivity down by up to 4%.
  • Employment levels are now 3‑4% lower than they would have been, with real wages only £43 a week higher on average after inflation.
  • Young people face the steepest participation decline, with NEET numbers exceeding one million – the highest since 2013.
  • Public support for Brexit has eroded: a recent YouGov poll shows 70% of Britons favour closer ties with the EU, and 56% back re‑joining outright.

Outlook: Persistent Drag and Shifting Political Landscape

Analysts warn that the economic drag will linger as trade frictions remain and investment recovery depends on policy certainty. With a majority now backing closer EU relations, future governments may face pressure to renegotiate aspects of the trade deal or consider a formal re‑entry, which could reshape the long‑term fiscal outlook.
