In this episode, Paolo Sironi speaks with Dr. Balakrishnan Mahadevan (Balu), author of Designing Change: My Journey Through India’s Digital Payments Transformation. India’s digital payments have grown from under one billion transactions annually around 2010 to over 225 billion by March 2025—a more than 200-fold increase. Through his unique lens as a former banking technology leader, COO of NPCI during its critical scaling years, and World Bank advisor, Balu offers a rare insider’s account of how this transformation actually happened. The conversation explores the book’s core message: that payments innovation is rarely about a single breakthrough. Instead, it emerges through decades of institutional development, regulatory leadership, collaborative ecosystem building, and combinatorial innovation—integrating real-time rails, mobile interfaces, APIs, and interoperable frameworks. Balu discusses the long journey from early electronic systems to real-time networks like UPI, the critical role of institutional design, overcoming early skepticism, and lessons for both developing and developed markets. The discussion highlights broader implications for digital public infrastructure, financial inclusion, and the evolving role of banks. This episode provides deep, practitioner-led insights into building scalable, inclusive financial systems.
