Why More Bank Clients Are Asking for Investment Management

For banks and trust companies, the core value proposition has long been clear: stewardship, fiduciary oversight, and the careful administration of assets held across generations. Today, clients are arriving with an additional expectation. They want their institution to manage their investments, too.
That shift isn't accidental. It reflects a broader change in how clients think about their financial relationships — and which institutions they trust to hold the full picture of their wealth.

The Forces Behind the Shift

Two dynamics are rewriting the competitive landscape for banks and trust companies right now. The first is the Great Wealth Transfer. Cerulli anticipates $124 trillion in wealth will transfer through 2048¹. Heirs are generally younger, more digitally fluent, and more demanding about what they expect from a financial relationship. Firms that built deep trust with the parent generation have a window to earn that same relationship with the next — but only if the service offering meets modern expectations. Investment management is typically part of what those heirs want.

The second force is competition. Registered investment advisors have been moving steadily into territory that once belonged almost exclusively to banks. They offer sophisticated portfolio management, tax-efficient rebalancing, and a client experience designed around clarity and responsiveness. The bar has moved, and clients notice.

Datos Insights research shows that the bank trust share of U.S. wealth management fell from 10% in 2016 to 7% in 2023². That decline isn’t evenly distributed. The bank trust groups gaining ground are the ones that have invested in modern investment management capabilities alongside their trust operations. The ones losing share are largely the ones waiting to see how things unfold.

What Clients Are Actually Asking For

When bank clients ask for investment management, they're asking for a few specific things: a coherent view of their assets, active portfolio management that accounts for their goals and tax situation, and reporting that makes sense alongside their trust holdings. What they don't want is to manage two separate relationships — one with their bank for trust services, one with an RIA for investment management — and reconcile the experience themselves. When that gap exists, it creates an opening for a competitor to close it.

The institutions that retain multigenerational relationships tend to be the ones that can hold the full client picture in one place. Trust administration and investment management working together, not in parallel.
 

The Infrastructure Challenge

The issue for most banks and trust companies isn't willingness — it's infrastructure. Many are running separate systems for trust accounting and investment management. Reconciling across those systems takes time, creates operational risk, and limits the ability to deliver the kind of reporting modern clients expect. That's the gap the market has struggled to close. Most platforms are strong on one side of the equation or the other. A system built for trust administration often lacks the trading depth a serious investment management operation requires. A platform built for RIAs often doesn't understand the omnibus custodial model, principal/income distinctions, or the compliance requirements specific to trust accounting.

The result is that banks and trust companies typically face a choice: optimize for trust administration and accept limits on investment management, or build toward investment management and manage the integration burden themselves.

The Path Forward

The banks and trust companies outperforming their peers right now aren't executing full platform replacements. Most start with their highest area of need — whether that's trading infrastructure, performance reporting, or client experience — and build from there.
What makes that approach work is technology that can meet them at each step: scalable trading, portfolio accounting that stays in sync with trust data, and a client portal that shows trust and investment assets together without requiring separate logins or exported PDFs. The next generation of clients treats that as a baseline expectation.

The urgency is real. Clients asking their bank about investment management today are deciding where that relationship lives. Banks with a credible answer keep it. Banks without one are handing an opening to a competitor who does.
