The next wealth boom: Emerging markets to add $12 trillion by 2030

The official story of 2025 was a banner year for the world's fortunes.

Global financial wealth rose 10.7% to a record $333 trillion, the fastest expansion since 2021, according to Boston Consulting Group's latest Global Wealth Report.

North America and Western Europe still hold the bulk of that money, and the year's defining headline was a status contest between two established hubs: Hong Kong overtook Switzerland as the world's largest cross-border booking centre, each holding around $2.9 trillion in international assets.

Yet, the fastest-growing sources of new wealth are no longer New York, London or Zurich. They are increasingly found in Mumbai, Jakarta, Riyadh, Ho Chi Minh City and São Paulo.

According to BCG, emerging markets, including China, are on track to generate approximately $12 trillion in additional financial wealth by 2030.

The affluent-and-above segment — households holding more than $250,000 in financial assets — is projected to expand by roughly 8% annually, creating more than one million new dollar millionaires before the decade ends.

A new geography of wealth

Unlike previous wealth booms, this one is not confined to a single country or region.

India is expected to account for the largest share of new wealth creation, adding more than $2 trillion by 2030. Brazil is forecast to generate roughly $1 trillion, while Mexico could add another $600 billion.

Yet the story stretches well beyond the largest economies.

Vietnam, Indonesia, Saudi Arabia and several Gulf states are all generating wealth at rates that rival or exceed many developed nations. What makes the trend remarkable is not simply its scale but its breadth.

The world's rich are no longer being created overwhelmingly in a handful of Western financial centres. New fortunes are emerging simultaneously across South Asia, Southeast Asia, Latin America and the Middle East.

For investors, private banks and luxury brands, the implication is straightforward: future clients will increasingly come from places that historically sat outside the traditional centres of global finance.

The rise of the ultra-wealthy

Knight Frank's 2026 Wealth Report offers a glimpse of how quickly the shift is unfolding at the very top of the wealth ladder.

India's population of ultra-high-net-worth individuals — those with assets exceeding $30 million — surged 63% between 2021 and 2026, and is projected to surpass 25,000 by 2031.

The consultancy describes India as an economy evolving from entrepreneurial dynamism into a market supported by deeper capital pools, more sophisticated financial markets and a growing class of globally connected founders and investors.

Yet India is not the fastest-growing market.

Indonesia is projected to record the world's strongest expansion in ultra-wealthy individuals over the next five years, with an 82% increase. Saudi Arabia and Poland are forecast to grow by more than 60%, while Vietnam is expected to post growth approaching 60%.

The Gulf region is becoming an increasingly important wealth hub in its own right.

The Middle East's share of the global ultra-wealthy population has risen from 2.4% to 3.1% over the past five years, while Saudi Arabia is forecast to record the world's fastest growth in billionaires through 2031.

Billionaires, in particular, are dispersing. Asia-Pacific now hosts more of them than any other region, ahead of North America, a quiet reversal of the old hierarchy.

For Knight Frank, the generational shift is part of the appeal.

Asia's younger wealthy, says Christine Li, the firm's head of research for Asia-Pacific, are "more attuned to innovation, technology and demographics" and that is steering where they invest.

Mumbai shows what the boom looks like

Few cities illustrate the transformation better than Mumbai.

Knight Frank describes India's financial capital as a "domestic giant" whose growth is driven primarily by home-grown wealth rather than foreign capital.

Prime residential property prices rose 8.7% in 2025, supported by an economy that has expanded by nearly 40% over the past five years. Demand for luxury homes has accelerated, with dozens of transactions above the $5 million mark recorded during the year.

Unlike many global luxury property markets, Mumbai's boom is being fuelled by local entrepreneurs, technology founders, industrialists and investors.

"Mumbai has enormous growth potential ahead," said Ankita Sood, national director of research at Knight Frank India, pointing to a steady climb in super-prime sales.

The city increasingly resembles what New York, London and Hong Kong represented during earlier phases of wealth creation: a magnet for domestic capital and ambition.

The question for the decade ahead

The numbers point in one direction: the centre of gravity in global wealth creation is drifting away from the markets that have long defined it.

Yet whether this becomes a lasting reordering of global wealth remains uncertain.

Geopolitical tensions, trade fragmentation, energy shocks and growing political backlash against wealth concentration could all alter the trajectory.

The conflict in the Middle East has already reminded investors how quickly economic assumptions can change.

For now, however, the trend is unmistakable.

The world's wealthiest nations may still hold most of today's money. But a growing share of tomorrow's fortunes will be made elsewhere.
