The Cost of Complexity: Why Simplification Is Back on the CEO Agenda

Complexity is the silent tax on banking performance. Legacy systems, product proliferation, organisational layers, and fragmented processes accumulate over years - each individually justifiable, collectively crippling. Global Banking Monitor's 58-page report investigates why simplification has returned to the CEO agenda and what successful programmes look like in practice.

Key findings

• Complexity costs are significantly underestimated. Most banks cannot accurately quantify the financial and productivity impact of their complexity, making it difficult to build a business case for simplification - even when the drag is obvious.
• Technology complexity is the largest single contributor. Fragmented architectures, thousands of applications, and integration layers built over decades create operational fragility and consume disproportionate IT budgets on maintenance.
• Product proliferation erodes margins invisibly. Banks that have allowed product catalogues to grow unchecked find that long-tail products generate minimal revenue but significant operational and compliance cost.
• Simplification programmes often fail because they add complexity. Transformation initiatives that layer new capabilities on top of existing systems without decommissioning the old create more complexity, not less.
• Cultural resistance is the primary execution barrier. Simplification requires retiring things people built and are attached to. Without executive sponsorship and a clear mandate, programmes stall under the weight of internal politics.

Who should read this

This report is designed for CEOs, COOs, CIOs, and transformation leaders tasked with reducing operational complexity. It is equally valuable for board members seeking to understand why cost programmes deliver diminishing returns without addressing underlying structural complexity.
