4:42From your perspective, why is it important to document India's digital payment journey not merely as a technology success but as a story of institution building?
7:49Now I get to the question on leadership, regulators and founding institutions, right?
14:16You know what lessons does it offer other sectors or even other countries?
17:16In your view, what should leaders and institutions be most mindful of as they grow at scale?
21:23Across industries and sectors, how should leaders balance scale, efficiency and innovation with a broader societal good rather than serving only the shareholders?
27:57For the students and young professionals here today, what are one or two lessons from your journey would you emphasize as they seek to build institutions or organizations that truly serve the society?
Good evening. Thank you everyone for being here for this book launch event. It is actually not even about writing a book but also about being able to translate what has been asked to shorter videos to be able to communicate to an audience which values that. So those are things that Badu has done in the last one year and I think this book will serve as a reference point for coming back and realizing what we have done in the past. Not only about the history, we look back at the rearview mirror not so much to drive backwards, we look at the rearview mirror to be able to drive forward better. So the rearview mirror that Badu brings about is also about helping us drive better as we move forward. So it's a great rearview mirror for India's digital banking and payment systems and I wish this book serves as a good reference point for not only academics but also policy. Thank you very much.
This is not a book about one product or one service. It is not a book about UPI alone, not about a single institution. Rather, it is a book about India's digital payments transformation as a whole. At its core, it is a book about how India built digital payments as public infrastructure through institutional design, governance and careful sequencing rather than through any one technology or product. Therefore, especially meaningful to have our chief guest with us today. Someone who has spent a lifetime building institutions that endure, who served as chairman of NPCI during his formative years and who has graciously written the foreword to the book. The vision and the foundation laid during his early years have had a lasting influence and have played a significant role in shaping NPCI to what it is today. Thank you sir. I look forward to the conversations. Sir, you have graciously written the foreword to this book and I have seen this journey closely over many years. Before I move into the conversation, may I invite you to share your opening reflections on the book. Thank you.
Well, this is a very important book because there is enough value in it and it is even more important because India has become the leader in the digital world today. As I was reading somewhere, India's digital transactions are something like four times that of the US and Europe combined and that is extraordinary. And also to be able to handle 20 plus billion transactions in a month. I mean that is extraordinary to build technology that has the resilience to handle that volume, to do it in a very smart way thanks to extraordinary people like Shri Gandhi and other leaders of RBI and thanks to the extraordinary wisdom of Shri Balachandran from which all of us benefited. I was very lucky to have worked with him for several years. So I think there is a lot of value in the book both for learning about a very important paradigm of the current century which is digital payment systems and at the same time how every one of us through smartness, hard work and discipline can indeed reach the pinnacle of our aspirations. That's what I would say.
Thank you sir. Thank you so much for that. The first question is about the book and the institutional memory. Sir, you were kind enough to write the foreword for the book. From your perspective, why is it important to document India's digital payment journey not merely as a technology success but as a story of institution building?
Well, technology in some way is a perishable commodity. Particularly in the era that we live in, things change rapidly, technology changes rapidly. For example, all of you know that one of the challenges that people have today is buying which Nvidia chip that you want to buy because by the time you get it installed and all of that a new version would have come up. So in such an era, the only constant for us is change. Fortunately for us in the West there are a lot of books that have been written on various technologies that are available, we can all benefit from that. However, for various reasons, India has not been a written tradition or an oral tradition. So therefore, this brings out the complexity of working in teams, the kind of encouragement that an institution like RBI provided, how RBI was such a fantastic catalytic enabler because I was the first chairman and I benefited a lot on the one hand from the wisdom of the governor and the deputy governor and all of that. These are all things that have to be documented and that's what therefore I do believe that documenting institutional memories, documenting the interaction of personalities, documenting the strengths and fibers of leaders, documenting the constraints posed by the context. All these are as important as technology. So I do believe that we need books like this so that the foundation of India's progress even further will rest on such wonderful knowledge.
Thank you sir. That's wonderful. Thank you. Now I get to the question on leadership, regulators and founding institutions, right? Looking back at the creation of an institution like NPCI sir and the broader digital payment ecosystem, what were the most important leadership choices and how did regulators like RBI, the promoter banks and Indian Bank Association and the founding teams together contribute to building an institution that earned trust and endured over time.
Well, you know, continuing from what I said earlier, this book in some way describes the organizational choreography of this wonderful dance played by RBI, NPCI, the wonderful banks of which several chairpersons are here and of course individuals. If I'm not wrong there are somewhere around 500 banks which are members of the entire platform. And what is very important is the role of the Reserve Bank of India as a catalytic and very paternal and kind enabler. Since I was the chairman and since Mr. Balachandran and I were in some way interfacing with the RBI, we can say very confidently that the role of RBI was extremely important in this and they encouraged us very very positively. The second thing that I am most impressed with, the masterstroke that RBI played in this game was making it a public good. The entire core of the UPI was made a public good. It was made an open, it was really an open system. And by doing this, what they did was they made it least expensive for every user. I don't know if there's any other nation in the world where access to banking, access to the devices of UPI is as inexpensive as it is in India and that credit must go to RBI. There is absolutely no doubt. But the characteristic of a confident leader which he has been is to be able to listen to cogent arguments from the followers and then accept when they have merit. That's another thing. The third thing is they decided that this core cannot be used for rent seeking. Therefore, they made the core an open system. They made the core a technology that is least expensive, a technology that the poorest Indian can indeed aspire to use. All of that has happened thanks to this and thereby what they did was they earned the trust of the common man. You know a couple of years ago I had taken a friend of mine Montek Singh Ahluwalia to Mysore and as we were climbing the Chamundi hill there was a coconut vendor and we bought some coconut water and all and we used UPI and Montek was very very impressed. You know this guy is just selling coconuts and the whole transaction was cashless. And that I think is, I don't know, particularly the youngsters assembled here must understand that when you have leaders who have a broad vision, who have high aspirations, who are well-intentioned, how such leaders can indeed transform the aspirations of the nation and become leaders in the progress. And this is a classical example to me. And of course there have been many other players, my own colleague Nandan Nilekani has played a very important role by bringing in Aadhaar and all of that. So I think RBI's role was being a catalytic, kind, gentle and wise enabler rather than just being a regulator. I think that to me is the most important thing.
Wonderful. You talked about frugality, you know, the way in which we do NPCI. You talked about cost of transactions and I had the opportunity to look at the 24-25 balance sheet of NPCI. NPCI does 230 billion transactions for a 2,300 crores expense which means they're able to do a transaction at 10 paise per transaction. Of this 10 paise, if you remove the marketing expenses, actually the operating cost of transaction is only 5 paise per transaction. I have reflected that in the book so I think if other countries can learn one lesson it is this lesson: how do you build a frugal system for the benefit of the nation. And you hit that point very rightly sir. Absolutely. Now let me go to the next question sir. You know this about public infrastructure versus private innovation, right? I think we talked a little bit about that. India's digital payment success rests on a distinctive balance between public infrastructure combined with private innovation at the edges, right? How do you view this balance? You know what lessons does it offer other sectors or even other countries?
