Banks cannot be everything to everyone anymore

By Tej Patel, Partner at Elixirr

For years, large banks pursued a simple ambition: to be everything to everyone. Offer every product, serve every segment and expand into every market. The assumption was that greater scale, broader reach and more capabilities would naturally lead to stronger performance and deeper client relationships.

That model is now under real strain.

The issue is not just commercial. It is structural. The capital, regulatory and operating burden of supporting a wide range of products and services across multiple geographies is becoming increasingly difficult to justify, particularly when those activities are not core to the bank’s strategy. In a lower-growth, margin-pressured environment, breadth is no longer a strategy in itself. In many cases, it is becoming a drag on returns, resilience and management attention.

Customers are changing too

At the same time, the customer logic behind universal banking is weakening. Many clients, especially younger generations, do not want one institution to meet all of their financial needs. They are more comfortable using different providers for different services, and their expectations are shaped by digital ecosystems, specialist propositions and seamless experiences.

That means banks are being challenged from both directions. The supply side is more expensive, more regulated and more complex. The demand side is more fragmented, more selective and less loyal to the idea of a single financial provider.

In that context, offering more is no longer a guaranteed route to stronger relationships or better returns.

The real cost of accumulated complexity

Most large banks do not suffer from a lack of ambition. They suffer from accumulated ambition. Each leadership team adds new priorities, new capabilities, new platforms and new markets. Each decision may make sense in isolation, but over time they create overlapping portfolios, fragmented operating models, and increasingly entangled technology estates.

What looks like scale on paper often feels like friction in practice. Every additional product, entity and geography brings more capital demands, more regulatory obligations, more governance complexity and more operational interdependencies. Where those activities are subscale or non-core, the burden can quickly outweigh the value they create.

At that point, complexity stops being an inconvenience. It becomes a strategic risk. It raises operating costs, slows down change, makes regulatory expectations harder to meet and weakens resilience. When incidents happen, disruption can travel across the organisation in ways that are difficult to predict and even harder to contain.

A more sustainable path to growth

The answer is not to retreat from growth. It is to pursue growth with more discipline.

That starts with sharper strategic focus. Banks need to be clearer about where they can genuinely lead, and more willing to make active choices about the products, client segments and geographies that are truly at the core. That judgment should be shaped not just by internal capability and economics, but by how customer behaviour is changing.

It also means being more realistic about how new capabilities are built. Not every opportunity needs to be owned outright. Partnerships and joint ventures can give banks access to innovation, specialist capability and new distribution without forcing them to carry the full cost and complexity of building everything in-house.

But partnerships only work if they are part of a deliberate operating model. Without strong architecture, governance and controls, they simply create a different form of complexity.

Growth decisions are now resilience decisions

This is why growth decisions need to be treated as resilience decisions. When a bank considers an acquisition, a new market entry or a major investment, the question is no longer just whether it will grow revenue or reduce costs. The question is whether it will make the organisation stronger, simpler and more resilient over time.

That requires risk, operations and technology leaders to be involved much earlier in strategic decisions. If they are brought in too late, banks often spend years paying for growth through integration effort, added control burden and avoidable operational risk.

Reframing ambition

The banks that will perform best in the next phase will not be the ones trying to do the most. They will be the ones that are clearest about where they can win, most honest about what is non-core and most disciplined about the complexity they are willing to carry.

The era of trying to be everything to everyone is coming to an end. The winning model now is not a universal scale at any cost. It is focused growth, backed by sharper choices, better partnerships and a much clearer view of resilience.

Because in banking today, complexity is not just expensive. It is increasingly unsustainable.
