Brexit impact on business investment leaves UK lagging behind Europe

When Britain voted to leave the EU in 2016, opinions were sharply divided about what it would mean for the economy. Those who voted for Brexit had a firm belief that it would unleash a new era of growth and investment, free from the EU’s constraints. Those who opposed Brexit predicted a bleak economic outlook.

Now, almost 10 years on, the data supports the views of those who wanted to remain in the EU.

A study by economists at Stanford University, the Bank of England, and the National Institute of Economic and Social Research estimates that UK business investment is 12 to 18 per cent lower than it would have been if Britain had stayed in the EU. Researchers used almost a decade of data since the referendum, combining simulations based on macro data with estimates derived from micro data collected through surveys.

The chart above tracks how business investment has changed across advanced economies since 2012. While investment elsewhere continued to climb, the UK’s line breaks away and flattens. By 2024, the red line representing the UK trails clearly below other countries.

The story is not one of a dramatic crash, but of stagnation. After the referendum, UK business investment stopped growing, even as other major economies such as Germany reported steady gains. That gap has only widened over time.

Today, the UK’s productive capacity from factories and digital infrastructure to research facilities is smaller than it might have been.

The road not taken

The yellow “UK synthetic” line in the chart shows what might have happened if Britain’s investment levels had followed the same path as comparable economies and without Brexit. By 2024, that line is about 15 points above today's level. Investment elsewhere rebounded quickly after the pandemic. In Britain, it barely moved.

Before 2016, the UK’s business investment was growing at about 6 per cent a year, one of the strongest rates among G7 states. After the vote, that growth collapsed to almost zero. The Bank of England’s Decision Maker Panel found that companies that were heavily dependent on EU trade cut investment by 16 per cent, and the National Institute of Economic and Social Research estimates that UK business investment is 12 to 18 per cent lower than it would have been if Britain had

Based on the UK’s pre-referendum investment level of about £230 billion ($301.5 billion) a year, the cumulative loss by this year could be £275 billion or £400 billion.

Even after the pandemic, as global investment recovered, UK companies stayed cautious. By early 2024, investment in other advanced economies was up by about 25 per cent compared with 2016 levels. In the UK, it had risen by just 4 per cent.

What’s driving the gap?

The study points to four main reasons for this long-term decline:

  • Uncertainty: The biggest factor. Brexit negotiations created years of unpredictability for businesses and investors. Many companies postponed or cancelled major projects until they understood what trading outside the EU would look like.
  • Trade friction: New customs checks and diverging regulations increased costs, especially for exporters and service providers tied to EU markets.
  • Management distraction: Senior teams in government and finance spent years planning for Brexit, diverting time and resources from innovation and expansion.
  • Misallocated resources: Some companies moved parts of their operations to the EU – opening new subsidiaries or shifting staff – often at the expense of more productive activities at home.

Together, these factors have left a dent. The study estimates that weaker business investment accounts for about a third of the total GDP gap now linked to Brexit.

Torno Subito by Massimo Bottura

When the W Dubai – The Palm hotel opens at the end of this year, one of the highlights will be Massimo Bottura’s new restaurant, Torno Subito, which promises “to take guests on a journey back to 1960s Italy”. It is the three Michelinstarred chef’s first venture in Dubai and should be every bit as ambitious as you would expect from the man whose restaurant in Italy, Osteria Francescana, was crowned number one in this year’s list of the World’s 50 Best Restaurants.

Akira Back Dubai

Another exciting opening at the W Dubai – The Palm hotel is South Korean chef Akira Back’s new restaurant, which will continue to showcase some of the finest Asian food in the world. Back, whose Seoul restaurant, Dosa, won a Michelin star last year, describes his menu as,  “an innovative Japanese cuisine prepared with a Korean accent”.

Dinner by Heston Blumenthal

The highly experimental chef, whose dishes are as much about spectacle as taste, opens his first restaurant in Dubai next year. Housed at The Royal Atlantis Resort & Residences, Dinner by Heston Blumenthal will feature contemporary twists on recipes that date back to the 1300s, including goats’ milk cheesecake. Always remember with a Blumenthal dish: nothing is quite as it seems.
