Britain is on course to re-enter the world’s economic top tier by 2040. Long-term projections from the Centre for Economics and Business Research (CEBR), a London-based economic consultancy whose forecasts are widely cited by governments, central banks and international media, indicate that the United Kingdom could become the fifth-largest economy globally in nominal GDP terms, overtaking Japan and ranking behind only the United States, China, India and Germany.
“CEBR modelling suggests GDP per head could rise from roughly $55,000 today to around $75,000 by 2040, yet still lag behind EU states such as Germany and the Netherlands”
CEBR estimates that UK GDP could expand from just under $4 trillion in the mid-2020s to approximately $6.8 trillion by 2040. This equates to average annual nominal growth of around 3.5 – 4%, supported by population growth, relatively high employment and modest productivity gains. Britain’s rise in the global rankings is driven not only by domestic expansion, but also by slower growth in other advanced economies. Japan, for instance, is projected to grow at well below 1% annually in nominal terms, constrained by demographic decline and long-standing structural weaknesses.
On the surface, the forecast suggests renewed global economic prominence. The implications for living standards at home, however, are far less clear-cut.
The broader global landscape continues to shift. The United States is expected to remain the world’s largest economy into the 2040s, with China narrowing the gap and potentially overtaking it later in the decade. India’s economy is forecast to more than triple in size, moving into third place by the mid-2030s. By contrast, most large European economies are expected to grow more slowly, reflecting ageing populations and persistent productivity challenges.
“The US is expected to remain the world’s largest economy into the 2040s, with China narrowing the gap and potentially overtaking it later in the decade”
Britain’s difficulty lies not in the scale of its output, but in how that growth translates into individual prosperity. On a per-capita basis, commonly used as a proxy for living standards, the UK is projected to slip down the global rankings over the same period. CEBR modelling suggests GDP per head could rise from roughly $55,000 today to around $75,000 by 2040, yet still lag behind EU states, such as Germany and the Netherlands. As a result, Britain may fall from around 19th place globally to the low 20s.
“By 2040, Britain’s place in the world economy may appear stronger. The question is whether life at home will feel any more prosperous”
Productivity remains a central constraint. UK output per hour worked is estimated to be around 15 – 20% lower than in Germany and the United States, while productivity growth has averaged below 0.5% a year since the global financial crisis. Wage growth has struggled to offset this weakness, particularly following the recent surge in inflation, which eroded real household incomes and purchasing power.
The outcome is a familiar paradox. Britain may be getting larger in economic terms, yet not necessarily richer in ways that are felt by households. Whether a return to the global top five translates into rising living standards will depend less on headline GDP rankings and more on sustained improvements in productivity, investment, skills and real wages.
By 2040, Britain’s place in the world economy may appear stronger. The question is whether life at home will feel any more prosperous.
