The UK’s long-term economic growth could outpace leading EU countries like Germany, France and Italy, even despite some medium-term drag from Brexit, according to new analysis by PwC. PwC’s The World in 2050 report forecasts that by 2050, the UK will have fallen by just one place from 9th to 10th in global economy rankings, measured by purchasing power parity (PPP) [see Notes for PPP definition].

If measured instead by GDP at market exchange rates, the UK could fall from 5th to 9th place by 2050, but by either measure will remain a top-10 global economy. With potential average annual growth of around 1.9%, the UK is projected to remain the fastest growing economy in the G7 between 2016 and 2050. The UK’s position is sustained by its projected larger working-age share of the population than in most other advanced economies. However, PwC cautions that this strong growth potential depends on the UK continuing to attract and employ talented people from around the world, even after it leaves the EU.

Commenting on the forecast, John Hawksworth, chief economist at PwC, said:

“After a year of major political shocks including the EU referendum and the election of President Trump, it might seem brave to offer economic prospects for 2017, let alone 2050.

“But a long-term view is crucial for planning for issues like pensions, healthcare, energy and climate change, housing, transport and other infrastructure investment. By looking beyond unpredictable short-term economic and political cycles and focusing on fundamentals, long-term growth projections can actually be more reliable than short-term forecasts.

“Our relatively positive long-term growth projection for the UK reflects favourable demographic factors and a relatively flexible economy, even by European standards.

“However, developing successful trade and investment links with faster-growing emerging economies and recruiting workforce talent wherever in the world it can be found, are essential to achieving this growth and to offset probable weaker trade links with the EU after Brexit.”

PwC emphasises the importance of building strong political and trading relationships with new, emerging economies. Regardless of the outcome of the EU referendum, these economies were going to become dominant global economic forces, eclipsing many EU members and therefore essential to the UK’s ultimate long-term economic growth.

China has already overtaken the USA to become the world’s largest economy in PPP terms and will move further ahead by 2050. India currently sits in third place and is projected to overtake the US by 2050.

By 2050, Indonesia is expected to have moved up the rankings to fourth place, overtaking not just Germany and Japan but also Brazil and Russia. Germany and the UK remain in the top-10, but France falls to 12th place and Italy to 21st as it is overtaken by a succession of faster-growing emerging economies like Vietnam.

PwC projects that the world economy will double in size by 2042, growing at an average annual rate of just over 2.5% between 2016 and 2050, with growth expected to be driven largely by emerging market and developing countries. The E7 economies of Brazil, China, India, Indonesia, Mexico, Russia and Turkey are forecast to grow at an annual average rate of 3.5% over the next 34 years, compared to an average of just 1.6% for the advanced G7 nations of the US, Canada, France, Germany, Italy, the UK and Japan.

According to PwC, that means that the E7 could comprise almost 50% of world GDP at PPPs by 2050, while the G7’s share could decline to just over 20%. But emerging economy growth will also slow down over the period, as these economies mature and the scope for relatively easy ‘catch-up growth’ by importing advanced economy technologies is reduced over time.

PwC says these global shifts in economic power provide key policy messages for the UK and its devolved regions. Assuming continued access to EU markets post-Brexit, and ignoring the opportunities - and the challenges - offered by emerging markets would be a mistake. Even if the UK had voted to remain in the EU, it would have been necessary to look to these emerging markets for the next wave of growth.
