Aditya Puri's Legacy and the HDFC Bank Model the World Is Watching

When Aditya Puri stepped down as Managing Director and Chief Executive of HDFC Bank in October 2020, after nearly twenty-six years at its helm, he left behind something rare in global banking: an institution that had never reported an annual loss, had grown from a startup licence into one of Asia's most valuable financial franchises, and had done so with a consistency of culture and credit discipline that banking professionals across continents still study. Now, six years on from his departure, the architecture he built is being examined with fresh urgency — not as nostalgia, but as a working model for what sustainable retail banking can actually look like in an emerging market.

Building From Nothing

HDFC Bank was incorporated in 1994 and received its banking licence from the Reserve Bank of India, commencing operations in January 1995, during the early flush of India's post-liberalisation era. Puri, who had spent years at Citibank in Malaysia, was recruited to lead the new institution before it had opened a single branch. The challenge was considerable. India's banking sector was dominated by state-owned lenders with entrenched customer relationships, and public trust in private banking was far from assured.

Puri's response was methodical. He prioritised technology infrastructure at a time when most Indian banks were still largely paper-based, insisting that the bank's systems be built to scale rather than merely to function. That early bet on technology as a foundation — not an afterthought — would define HDFC Bank's competitive positioning for the decades that followed. Most rivals didn't see it coming.

The bank expanded steadily, extending its branch network across urban and then semi-urban India, building retail and wholesale banking operations in parallel, and cultivating a risk culture that, by regional standards, was unusually conservative. The result was a lender whose non-performing asset ratios stayed among the lowest in the Indian private sector across multiple credit cycles — including the turbulent years after the global financial crisis of 2008 and the stress in India's infrastructure lending sector in the early 2010s.

The Discipline of Credit

No aspect of Puri's legacy draws more study than his approach to credit risk. Indian banking has periodically cycled through episodes of aggressive lending followed by sharp deterioration in asset quality. HDFC Bank maintained a strikingly different posture throughout. Puri was consistently cautious about sectors where other lenders chased rapid growth, and he was willing to accept lower market share in certain product categories rather than loosen underwriting standards. That is a harder trade-off to make than it sounds, particularly when competitors are booking fees and investors are demanding growth.

This wasn't merely prudential instinct — it was embedded in how the bank hired, trained, and evaluated its people. Credit decisions were treated as a cultural matter, not simply a procedural one. The distinction matters enormously in practice.

That discipline allowed HDFC Bank to stay profitable through periods when peers faced significant provisioning pressures. It also built a reputational asset that translated directly into customer acquisition, particularly among the urban middle class, which came to regard HDFC Bank as synonymous with reliability. That perception has proven durable even after Puri's exit — which is the real test of whether a culture was ever genuine.

Technology as Strategy, Not Decoration

Puri's push on technology investment came long before "digital banking" entered the industry's vocabulary. When the smartphone revolution eventually transformed how Indians interacted with financial services, HDFC Bank was ready to move quickly because its core banking infrastructure had already been built with scale in mind. The bank became a significant player in mobile and internet banking, and its payments and digital product offerings expanded substantially during the latter years of Puri's tenure.

There were setbacks. Around 2020, HDFC Bank experienced a series of technology outages that drew regulatory scrutiny from the Reserve Bank of India, which temporarily restricted the bank from issuing new credit cards and launching certain digital products. It was an uncomfortable moment. The episode showed that even well-resourced institutions carry infrastructure vulnerabilities as transaction volumes scale — a lesson the broader industry should have absorbed more carefully.

What it also showed was something about the culture Puri had built. The bank addressed the issues systematically, engaged regulators constructively, and ultimately restored its product launches after demonstrating remediation. The outages didn't rewrite the story of technological seriousness. They tested it, and the institution held.

Scale, Succession, and the Merger Question

Sashidhar Jagdishan succeeded Puri as Managing Director and Chief Executive in October 2020, inheriting a bank of enormous scale — and then overseeing its expansion into something still larger. The merger of HDFC Limited, the housing finance company that had been the bank's founding parent, with HDFC Bank was completed in 2023, creating one of the largest financial entities in Asia by market capitalisation. Few transactions of this size in financial services go smoothly. Many disappoint spectacularly.

This one didn't — at least not yet. The integration process, while ongoing in various dimensions, has proceeded without the severe disruption that sceptics anticipated. That itself is worth noting, given the complexity involved in stitching together different product lines, regulatory frameworks, and institutional cultures.

For those studying Puri's legacy, the merger raises an interesting analytical question: how much of what makes HDFC Bank distinctive was about one particular man, and how much was genuinely institutionalised into its processes and values? Early evidence suggests the latter may be more robust than critics expected. But the full answer will take several more years to establish. Watch this space.

What the World Is Watching

In boardrooms and business schools from London to Singapore, HDFC Bank's trajectory is examined alongside a short list of institutions — DBS Group, Banco Bradesco, a handful of others — that are seen as proof that banking can be done thoughtfully in markets carrying higher volatility and institutional uncertainty than their developed-world counterparts. The common threads across these cases are not exotic: strong governance, consistent credit culture, early technology commitment, and leadership that resisted the temptation to grow at any cost.

Puri didn't invent those principles. He applied them with unusual rigour over an unusually long period, in a market that offered constant temptation to do otherwise. The bank he built continues to grow, continues to face competitive pressure from traditional rivals and technology-driven challengers alike, and continues to carry the weight of very high investor expectations. That it does so from the foundation he constructed is, by any reasonable measure, an achievement that deserves more attention than it gets outside the region.
