The Ninety-Year Client and the Twenty-Year System

A few months ago, I met the head of retail wealth at a bank preparing to launch a retirement proposition. He had customers, capital, and a board mandate. What he lacked was a platform built to sustain a client relationship for forty years.

His core banking system could tell him what a customer owned that morning. It could not tell him what that customer might need at seventy-eight. Risk tolerance had been captured once, at onboarding, and never revisited. Reporting produced statements rather than trajectories. Like most wealth platforms I have encountered across three continents, the advisory workflow rested on a single assumption: the most important phase of a client's financial life is accumulation.

That assumption may now be the industry's most expensive legacy conundrum.

The arithmetic nobody priced in

U.S. life expectancy at birth reached 79.0 years in 2024, the highest level ever recorded, with women at 81.4 and men at 76.5 (CDC National Center for Health Statistics). Averages, though, understate the planning problem. A meaningful share of clients who reach sixty-five today will fund three decades of retirement, and neither they nor their advisors know in advance which ones. Meanwhile Cerulli Associates projects $124 trillion will change hands through 2048 (Cerulli Associates), most of it passing through households whose members will live long enough to spend, restructure and gift it again; several times over.

Longer lives do not simply extend the existing service model. They invert it. Accumulation is primarily a return problem. Decumulation is a systems problem. Sequence-of-returns risk, healthcare inflation, cognitive decline, care transitions, tax location, beneficiary changes and withdrawal strategy all interact over decades. The challenge is no longer optimizing a portfolio. It is orchestrating a financial life. They cannot be optimized independently. Actuaries have called managing lifetime income the hardest challenge in the field, one requiring adequacy, flexibility and sustainability to be solved simultaneously rather than sequentially (American Academy of Actuaries).

Most institutions have responded by buying products. Annuities, longevity funds, hybrid care policies, to name a few. These solve components of the problem, not the problem itself. A product is a component. Longevity is an operating requirement.

A market that had to start at the hard end

I did not learn this from a whitepaper. I learned it because the market I largely service never had the luxury of the easy phase.

In the GCC, roughly 35 million foreign nationals now live and work, and in the UAE expats make up close to 85% of the population (Al Jazeera). For decades, the retirement provision for that entire cohort was a lump-sum end-of-service gratuity—a single payment, unindexed, uninvested, handed over on the way to the airport. Surveys have consistently found the majority of expatriates hold no pension or guaranteed savings arrangement at all (Gulf News).

That gap forced faster institutional design than any mature market has attempted. Dubai International Financial Centre (DIFC) replaced gratuity accrual with a funded, invested workplace savings plan; the DEWS scheme crossed $1 billion in assets under administration by October 2025, having paid out a further $340 million to savers (DIFC). At federal level, Cabinet Resolution No. 96 of 2023 introduced a voluntary alternative end-of-service benefits system, letting private-sector employers direct gratuity contributions into regulator-approved investment funds (UAE Ministry of Human Resources and Emiratisation).

Interestingly, even though the country has a young population today, it is aging faster than we realize. The UAE's elderly dependency ratio sits at about 1.6 older people per 100 working-age residents today and is projected to reach 18.5 by 2050—a twelve-fold shift inside one generation (Healthcare Middle East).

When your client is a 52-year-old engineer from Kerala who has worked in the country for 20 years, holds assets in three currencies, and will likely retire in a fourth jurisdiction, with no pension anywhere, and then expects to support a parent and a child simultaneously, you cannot solve for that with a glidepath. You have to solve for it structurally and with an architecture.

Three things longevity-ready infrastructure actually requires

Building for that client taught my team three design principles that I think travel well to any U.S. RIA, broker-dealer, bank or insurer now confronting the same horizon.

First, time has to be a field in the data model, not a slide in the review deck. Most platforms store a client's risk profile as a static attribute. FTS treats horizon, liquidity need and obligation structure as living variables that re-evaluate against the portfolio on a periodic basis. Longevity risk compounds quietly; only continuous recalibration and constant rebalancing catches it early enough to be cheap to fix.

Second, decumulation needs to be a seamless workflow and not a reporting view. Withdrawal sequencing and beneficiary logic need to be modelled objects with their own governance, audit trail and approval path. This needs the same rigour that institutions already apply to trade execution. Where we deploy an advisory layer, guarded automation operates strictly inside the institution's approved product shelf, investment-committee views and risk rules. In a longevity context that discipline is not a compliance overhead; we believe it is the mechanism that protects clients whose capacity to self-advocate may decline over the very period the plan matters most or for the period that they plan for.

Third, continuity is a platform feature. Just as health records are easily transferable, succession and estate plans should be cross-border portable too. The data, document custody, and continuity of client servicing all belong in the core, not in a folder on someone's desktop. The client owns the data, the advisor retains the fiduciary responsibility and the platform ensures that continuity survives changes in people, firms or jurisdictions. This matters for firms as much as for households. More than one in seven U.S. advisors is now over the age of 60, concentrating succession risk in exactly the practices serving the oldest clients (AdvisorPro, via Wealth Solutions Report). The industry is aging alongside the people it serves. A plan designed to outlive its beneficiary must certainly be designed to outlive its advisor.

The window

There is an uncomfortable advantage in building from a market with no legacy to protect. We were never able to bolt longevity onto an accumulation engine, because there was no accumulation engine to bolt it onto. We had to assume, from the first architectural decision, that a client relationship might span half a century, several jurisdictions and at least one generational handover.

U.S. institutions have deeper capital, better data and far more sophisticated products than most firms. What they often do not have is permission to start over. That is a real constraint, but it is not an excuse. Modernization is a spectrum, and the highest-return moves are usually the least dramatic: decoupling the client-data layer from the product layer, making horizon a computed variable, and giving decumulation the same operational status as onboarding and accumulating.

The great wealth transfer will not be a single event. It will be a 30-year process, administered largely by systems designed for 20. The firms that recognise longevity as an infrastructure question rather than a product-shelf question will spend the next decade compounding advantage. The rest will spend it reconciling spreadsheets.

My Gulf banker eventually asked me the right question. Not "which retirement product should we launch?" but "what does our platform need to be true about a client in 2056?" That is the question I would put to every board in this industry.
