I had a few interesting conversations last week. They were with different executives, from different institutions, discussing different topics. Yet one theme kept surfacing – the wealth continuum.

It has been one of wealth management’s most accepted ideas. Build a relationship with a client early, support them as their wealth grows, and eventually move them from affluent banking into private banking.

It is a model that has shaped how retail-lined or universal banks hire bankers, segment clients, allocate resources and, ultimately, measure success.

But is it still fit for purpose?

The question struck me because today’s wealthy clients are behaving very differently from previous generations. They are wealthier, more global and far more comfortable maintaining relationships with multiple institutions. More importantly, they don’t necessarily view banking through the same lens as the banks serving them.

Does accumulating US$5 million or US$10 million automatically mean a client wants to become a private banking client? Not necessarily.

For some wealthy individuals, that sum may simply represent the pool of money they use for everyday banking. Their main investment portfolios may sit elsewhere, while a priority banking relationship serves practical needs and the convenience of a mobile app, credit card or branch network.

Ironically, some of these everyday transactions can be easier through a retail or priority banking relationship. Private banking, by design, often involves additional checks and approvals.

That raises an interesting question. Does crossing a wealth threshold really matter to the client? Or is it a milestone that matters more to the bank than to the client?

One executive illustrated this with an example. A client with around US$80 million remains in a priority banking relationship despite holding substantially larger investment portfolios with two global private banks. The reason? Legacy and convenience. The client uses the account for everyday banking, time deposits, a mortgage, credit cards and branch access, while keeping core investment assets elsewhere. As the executive put it: “Forcing that client to move into the private bank—that’s not my target.”

Perhaps that’s where banks need to rethink how they define success.

Should success be measured by how many clients are “upgraded” into private banking? Or should it be measured by how much of a client’s financial life they actually own?

After all, clients are not necessarily buying a label such as “priority” or “private”. They are buying capabilities.

None of this suggests the wealth continuum is obsolete. It remains an effective way of nurturing relationships and identifying future wealth creators. But as family wealth becomes more global, clients become increasingly multi-banked, and banking needs become more specialised, perhaps the industry’s traditional definition of progression deserves another look.

There is another irony. When clients fall below a private bank’s minimum threshold, they are often encouraged to top up or move elsewhere. Yet moving may offer a better experience. Rather than being one of the smallest clients in a private bank, they may receive greater attention by becoming one of the largest clients in an affluent banking segment.

The private banking ladder may still exist. The difference is that clients may not be climbing it in the way banks expect.
