Commonwealth’s economic momentum grows

A SIGNIFICANT range of business memorandums of understanding were sealed at the Commonwealth Trade and Investment Summit hosted in the City of London in April 2026.

However, momentum is growing for a much bigger economic prize for the 56-member organisation – an ambition that holds substantial strategic value for key Asean nations including Singapore, Malaysia and Brunei.

The potential larger business ambition on the horizon is a pan-Commonwealth trade liberalisation deal. This would build from the wide range of bilateral and plurilateral economic agreements currently in place between member nations.

While the economic potential of the Commonwealth is often overlooked, it is vast and growing. The bloc includes India, which is on track to become the world’s third-largest economy in the coming years.

Commonwealth gross domestic product was estimated at around US$14.2 trillion in 2022, and is projected to reach some US$20 trillion by 2029.

This forecast for speedy growth reflects the fact that so many of the world’s fastest-growing markets are in the Commonwealth, especially across sub-Saharan Africa, South Asia and South-east Asia.

Underpinning this is a demographic dividend: More than 60 per cent of Commonwealth citizens – around 1.5 billion people – are under the age of 30.

Intra-Commonwealth trade was about US$854 billion in 2022 and is forecast to surpass US$1 trillion as soon as 2026.

The intra-Commonwealth stock of foreign direct investment hit US$1.7 trillion, most of which was fuelled by industrialised members, including the UK, Canada and Australia, which have the potential to invest even more in the group’s high-growth markets.

At the heart of the Commonwealth’s core economic proposition is the fact that member countries already trade more and generate 10 per cent more investment with each other than with non-member countries.

Trade between Commonwealth nations comes with a cost advantage in that costs of trade are around 20 per cent lower on average.

This is because the 56 countries of the Commonwealth are a key platform for collaboration, connected by common institutions, shared legal traditions, and a rapidly expanding consumer base.

At the heart of this stands the English language (although French and Portuguese nations are also in the club), which strengthens bonds that can be leveraged to boost wider connectivity.

In the absence of existing tariff and non-tariff barriers between Commonwealth nations, this advantage would be even higher.

The Commonwealth’s scale and diversity create significant opportunities for innovation, investment and economic partnership.

A broader Commonwealth trade deal

Of course, there are significant, practical challenges to the realisation of a genuinely pan-Commonwealth trade bloc, including different levels of enthusiasm across the club.

To bypass these hurdles, the most realistic strategy is for “coalitions of the willing” to lead the way.

One of the Commonwealth’s key assets has long been its flexibility and adaptability.

In time, deeper economic ties could also boost the group’s geopolitical influence, helping small and mid-sized countries strengthen their bargaining power with great powers like China or the US.

The building blocks for this incremental approach already exist within mega-regional trade pacts. In Asia, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership already connects Singapore, New Zealand, Malaysia, Brunei, Australia and the UK.

Moreover, the African Continental Free-Trade Area, a continental market of more than 20 Commonwealth African nations including South Africa, Nigeria and Kenya, paves the way for a customs union.

These opportunities and challenges were aired at the recent summit, which gathered heads of governments, ministers and some 300 business leaders of the Commonwealth.

Under the theme “Commonwealth solutions to global challenges”, the summit raised issues for discussion, not only on the potential for a trade bloc across the club, but also wider topics such as artificial intelligence, sustainable energy transitions, infrastructure investment, health technologies, creative industries and the evolving financial landscape.

Pivotal actors are already moving. As a leader in the Commonwealth, the UK has strong reason to be at the vanguard of pushing for such an enhanced Commonwealth economic bloc.

It is already expanding its trade footprint across the Commonwealth, with exports to the region exceeding £60 billion (S$103 billion) as of 2026.

India also recently picked up the pace of trade liberalisation, striking deals with the UK and New Zealand.

The Commonwealth Heads of Government Meeting in November presents a stronger focus on sustainable and inclusive growth, building on the Singapore Declaration of Commonwealth Principles established 55 years ago, when the group’s leaders came together as equal partners to share challenges and advance cooperation.

Trade and investment are now at the heart of the Commonwealth’s renewal, as the Commonwealth’s secretary-general Shirley Ayorkor Botchwey recently declared.

The association’s business influence is only likely to grow, given its many fast-growing emerging markets, and the demographic dividend.

The most likely path to a bloc-wide trade deal is through coalitions of the willing that build from existing mega-regional trade pacts, leading the way on this agenda for others to join later.
