Wealth Bands as Infrastructure: Who Gets to Define What Wealth Is Worth?

fintech Joseph Kaufman

Executive Summary

Having wealth and having wealth that the financial system recognizes are two very different things.

That distinction sits at the foundation of the private wealth management industry.

Financial institutions don't simply serve "the rich." They classify people into wealth bands, establish thresholds for entry, and construct entire business models around the assets they can manage, monetize, and move.

At first glance, this looks like ordinary customer segmentation. Look a little closer, and something more interesting emerges: the industry has effectively built an infrastructure for deciding which forms of wealth matter.

Beaverstock, Hall, and Wainwright explored this phenomenon in Regional Studies, examining 400 UK wealth management providers and how they classified high-net-worth individuals (HNWIs) by investable assets and geography.¹ Their research suggests that wealth classification does more than describe a marketplace. It helps create the very customer categories the industry depends on.

Fast-forward to 2026. Capgemini reports 25.3 million HNWIs worldwide controlling $98.3 trillion in wealth.² Meanwhile, regulatory changes, evolving client expectations, and new financial technologies are challenging the assumptions upon which traditional wealth management was built.

The numbers are impressive. But the more interesting question isn't how many millionaires exist.

It's who decided what counts toward becoming one in the first place.

1. The Million-Dollar Line: A Number That Built an Industry

Somewhere along the way, $1 million became more than a financial milestone. It became an admission ticket.

Merrill Lynch and Capgemini established widely adopted wealth classifications in the mid-1990s, defining an HNWI as someone possessing at least $1 million in investable assets, excluding primary residences, collectables, consumables, and consumer durables.¹

The framework divides individuals into recognizable categories:

Individual firms expanded this framework. PricewaterhouseCoopers, for example, developed five wealth bands beginning with affluent clients holding $100,000 to $500,000 and extending to UHNWIs above $50 million.¹

What fascinates me about this model is that it measures neither the full economic value of a person nor necessarily their ability to generate wealth.

It measures something far more specific: how much of their wealth fits into the institution's existing financial machinery.

Consider two individuals.

One owns $25 million in fine art, a $10 million residence, and $2 million in a brokerage account.

The other owns $6 million in publicly traded securities.

By the standard classification framework, the first individual falls into a lower wealth band than the second, despite controlling substantially greater total assets.

Neither person's actual wealth has changed. Only the portion the institution chooses to count has changed.

This is where classification becomes infrastructure.

Traditional lenders segment customers around creditworthiness and repayment risk. Wealth managers segment customers around the revenue potential of investable assets.¹

Different metrics produce different incentives, different products, and ultimately different definitions of a desirable customer.

The wealth bands weren't designed to measure everything people own. They were designed around what the industry could service.

That distinction becomes increasingly important as technology changes what financial institutions can verify, value, and control.

2. Old Money, New Money, and the Business of Access

The private wealth industry has always understood that how someone acquires wealth can be nearly as important as how much they possess.

Beaverstock and colleagues identified 140 firms serving the HNWI-to-UHNWI market within their 400-provider UK database. Accountancy firms and banks each represented 23% of those providers, followed by law firms at 17% and asset managers at 16%.¹

But the more revealing distinction was between traditional private banking and the wealth management divisions of investment banks.

Established private banks such as Coutts, C. Hoare & Co., and Weatherbys positioned themselves around heritage, preservation, and long-standing relationships.

Only 9.1% of all surveyed providers explicitly marketed traditional values associated with inherited wealth. Nine private banks followed this positioning, compared with just one investment bank wealth management arm.¹

Investment banks took a different approach.

Fourteen of fifteen investment bank wealth arms emphasized asset-based segmentation, targeting clients whose wealth came from business ownership, executive compensation, financial markets, and liquidity events.¹

In practical terms, these institutions were pursuing different financial moments.

Traditional private banks wanted to preserve wealth already inside the system.

Investment banks wanted to capture wealth as it entered.

Consider the financial industry itself. According to the Centre for Economics and Business Research, City firms paid an estimated £10.2 billion in bonuses across approximately 354,000 jobs at year-end 2007, up from £3.9 billion in 2001.¹

The same institutions distributing enormous compensation pools were building businesses to manage that money afterward.

That's not an accident. That's an ecosystem.

J.P. Morgan similarly targeted entrepreneurs approaching IPOs, mergers, and acquisitions—moments when previously illiquid ownership stakes could become substantial pools of investable capital.¹

The liquidity event wasn't merely a change in the client's balance sheet. It was the moment their wealth became commercially accessible to the institution.

This is one of the most revealing aspects of the entire model.

Financial institutions weren't necessarily discovering new wealth. They were positioning themselves at the point where existing wealth became compatible with their services.

Coutts attempted to bridge these markets with specialized teams serving landowners, corporate executives, entertainers, and Americans relocating to Britain.¹

Different client histories. Different relationships with money. Different financial needs.

Yet all ultimately encountered the same central question: what assets can the institution manage?

Research limitation: The original study analyzed how providers described themselves on their websites. These findings demonstrate marketing strategies, not independently verified client composition or realized revenue.

3. Geography: Following the Money Until the Money Moves

Wealth management isn't simply about identifying valuable clients.

It's about predicting where those clients will congregate.

In the researchers' UK dataset, 286 of 400 firms—72%—maintained headquarters in London. Another 43 operated from elsewhere in South East England, while 13 were based in Edinburgh.¹

Between 2002 and 2009, the Sunday Times Rich Lists placed an average of 51% of the UK's wealthiest 1,000 individuals in London and the South East.¹

Financial services followed concentrations of wealth, reinforcing the commercial advantages of those locations.

But geographic clustering introduces a dependency that wealth managers can't entirely control.

Government policy.

London's historical attractiveness reflected not only financial-market infrastructure and deregulation after 1986 but also tax treatment that benefited internationally mobile wealthy residents.¹

When those incentives change, the location's competitive position can change with them.

The original researchers recognized a broader geographic transition already emerging in 2008.

China's HNWI population reached approximately 364,000 that year, surpassing the UK's 362,000. India, China, Brazil, and South Korea were among the fastest-growing HNWI markets during the preceding period.¹

Their prediction was straightforward: wealth management firms would increasingly follow capital toward Asia and the Middle East.

That prediction has proved directionally significant.

But I think it also exposes a deeper characteristic of the industry.

A financial center is not simply where wealth exists. It is where legal, regulatory, technological, and commercial systems make that wealth useful.

And those advantages aren't permanent.

4. From 2008 to 2026: The Wealth Has Grown, but the Model Is Under Pressure

Capgemini's World Wealth Report 2026 estimates that the global HNWI population reached 25.3 million in 2025, an increase of 7.9%, with aggregate wealth of $98.3 trillion.²˒⁴

Compare that with approximately 8.6 million HNWIs holding around $33 trillion in the 2008 baseline discussed by the researchers.¹

These are nominal historical comparisons, not inflation-adjusted measures of purchasing power.

The industry has expanded enormously, yet the basic classification architecture remains recognizable.

Capgemini continues to place the UHNWI threshold at $30 million. Its 2026 reporting identifies approximately 250,000 UHNWIs, up 9.4% in 2025.²˒⁵

That relatively small population controls 34.8% of HNWI wealth, while the $1 million to $5 million band holds 42.5%.⁶

The concentration of assets creates obvious incentives for providers to compete aggressively for the wealthiest clients.

Geographically, Asia-Pacific now accounts for approximately 9.3 million HNWIs, compared with 9.2 million in North America and 6.1 million in Europe.⁶

The United States added approximately 736,000 millionaires in 2025, reaching 8.7 million.²

Meanwhile, the United Kingdom's HNWI population grew 2.6%, with wealth increasing 4.1% to more than $2.4 trillion.⁴˒⁷

Yet the UK presents a particularly interesting contradiction.

On April 6, 2025, the government ended the longstanding remittance-basis non-dom tax regime and moved toward residence-based treatment of worldwide income and gains, with related estate-tax changes.³

HMRC projections suggested approximately 14,800 individuals would qualify for the replacement four-year Foreign Income and Gains regime, compared with 73,700 non-dom claimants in 2023–24.³

Some wealth migration consultancies forecast a net UK outflow of 16,500 millionaires during 2025, although those estimates remain disputed.³

What matters here isn't proving that every forecast materialized.

It's recognizing that wealth management businesses built around particular jurisdictions can face structural disruption when the incentives supporting those jurisdictions change.

There is another challenge.

Capgemini reports that 88% of HNWIs now use multiple wealth management firms, seeking, among other benefits, better access to alternative investments.⁴

The era in which one institution could reasonably expect to capture a client's entire financial relationship is under pressure.

Clients have more options, assets are distributed across providers, and access matters as much as traditional loyalty.

Wealth management is gradually becoming less about owning the client relationship exclusively and more about earning a place within a wider financial ecosystem.

That changes the competitive equation considerably.

5. The Assets the System Doesn't Count

This is where the research becomes particularly interesting from a financial technology and infrastructure perspective.

The traditional classification system excludes primary residences, collectables, consumer durables, and various other assets from the investable wealth calculation.¹

It does so for practical reasons.

Traditional wealth management businesses were built around assets that could be valued, held in custody, traded, financed, and charged recurring fees.

A publicly traded security fits that operating model.

A rare painting, privately held business interest, or unusual physical asset presents far more complications.

The original researchers observed that wealth managers nevertheless offered art advice, jewellery advice, and insurance services for luxury assets including yachts and private aircraft.¹

These assets were economically relevant to clients, but they occupied a different place inside the provider's commercial framework.

The institution could advise around them without necessarily treating them as investable assets under management.

That is an important distinction.

An asset doesn't become less valuable simply because an institution hasn't developed the infrastructure to recognize it.

This raises a question that I believe deserves much more attention:

What happens when technology begins removing the operational reasons those assets were excluded?

Consider the capabilities required to bring an unconventional asset into a more sophisticated financial system:

  1. Ownership verification: Establishing who legally controls the underlying asset.
  2. Reliable valuation: Producing defensible pricing supported by evidence and market conditions.
  3. Transferability: Creating legally enforceable mechanisms for transferring ownership or defined economic rights.
  4. Risk monitoring: Understanding changing values, encumbrances, counterparty exposure, and potential threats.
  5. Control and recovery: Establishing safeguards and enforceable procedures when assets, counterparties, or transactions fall out of compliance.

This is where emerging digital asset infrastructure, tokenization, automated compliance, and programmable financial controls enter the discussion.

However, tokenization alone doesn't solve these problems.

Putting a digital representation of an asset on a blockchain doesn't automatically establish legal ownership, improve liquidity, validate pricing, or make a bank willing to accept it as collateral.

Those capabilities require an integrated combination of legal agreements, trusted data, market infrastructure, and enforceable controls.

In other words, the breakthrough isn't turning every asset into a token. It's making more assets verifiable, governable, and financially actionable.

That is a far more consequential infrastructure opportunity.

There is also a major difference between giving an institution the ability to service an asset and persuading an established wealth-reporting provider to count it inside an existing classification band.

The latter requires changes in methodology and institutional acceptance.

The research does not demonstrate that such reclassification has already occurred, and its timing remains uncertain.

But the underlying opportunity is worth examining.

6. The Next Wealth Management Opportunity May Be Redefining the Addressable Market

Most discussions about the growth of private wealth management begin with demographics.

How many new millionaires are being created?

Where are they located?

Which firms are best positioned to capture their assets?

Those are legitimate business questions, but they operate within the industry's existing definition of investable wealth.

I think a more interesting question sits one layer below them.

What happens to the size of the addressable market when previously difficult-to-service assets become accessible to financial institutions?

Imagine an entrepreneur with substantial ownership in a private company, an investor holding interests in specialized real-world assets, or a collector whose portfolio carries significant economic value.

Historically, portions of that wealth may have existed outside traditional wealth management workflows.

Not because the value was imaginary, but because the operational requirements for managing it were difficult, expensive, or poorly standardized.

If emerging infrastructure can make certain assets more transparent, transferable, and controllable, financial institutions may eventually develop services around assets they previously treated as peripheral.

That could expand the range of assets eligible for custody, financing, risk management, and investment services.

But it would not happen uniformly. Asset quality, enforceable rights, liquidity, counterparty risk, and regulatory requirements would still determine what financial institutions could reasonably support.

The opportunity isn't to pretend every asset is interchangeable.

It's to build the infrastructure that makes more categories of assets usable without ignoring their differences.

This shifts the conversation from wealth classification to financial system architecture.

And it exposes a subtle but important possibility:

The next meaningful expansion of wealth management may come not only from the creation of new wealth, but from better infrastructure for recognizing and servicing wealth that already exists.

7. Final Thoughts: Classification Is a Business Model, Not a Law of Nature

The private wealth industry spent decades refining a framework that tells institutions which clients to pursue, where to find them, what products to offer, and how much revenue to expect.

That framework helped create a highly specialized, globally distributed financial services ecosystem.

Its success is undeniable.

But the research also reveals that classifications reflect the capabilities, incentives, and limitations of the institutions creating them.

The $1 million HNWI threshold is useful.

The distinction between traditional and newly created wealth is commercially meaningful.

Geographic concentrations influence where firms build operations.

Yet none of those conventions should be mistaken for a permanent boundary around economic value.

As financial infrastructure evolves, institutions may discover that some of their assumptions about serviceable assets were reflections of yesterday's operational constraints rather than tomorrow's possibilities.

The winners won't necessarily be the firms with the most elaborate definitions of wealth.

They may be the firms capable of safely and reliably working with a broader range of it.

Wealth doesn't begin when a financial institution recognizes it. But the financial opportunities available to that wealth often do.

And to me, that's the real story behind the wealth bands.
