This book provides a unique, execution-oriented institutional architecture for banking that unifies hybrid delivery, governance, trust, inclusion, and operational discipline within a single, coherent framework, with application to retail banking systems operating at scale.
Digital transformation, regulatory pressure, shifting customer expectations, and rising inclusion mandates have fundamentally altered how banking financial institutions must be designed, governed, and operated. Yet much of the existing literature treats retail banking as a technology or channel problem, rather than as a complex institutional system that must function reliably at scale. Drawing on decades of real-world banking experience across multiple geographies, this book examines how retail institutions can be deliberately designed to balance execution, trust, inclusion, resilience, and long-term sustainability. Global in perspective and grounded in execution, it serves as a reference work for those responsible for shaping the future design of modern banking institutions.
The Future of Retail Banking provides senior leaders, regulators, policymakers, and practitioners with a practical lens for navigating hybrid operating models, open finance ecosystems, ESG responsibilities, and long-term institutional resilience.
