How IDFC FIRST Bank Tried to Rebuild a Bank Around the Retail Customer

Most banks refine their strategy. IDFC FIRST Bank had to replace one.

The bank traces its roots to IDFC, an institution set up to finance Indian infrastructure — roads, power, ports. That's lending with long tenures, large tickets, and concentrated risk. In 2018, IDFC Bank merged with Capital First, a retail-focused NBFC led by V. Vaidyanathan, who became the combined bank's CEO. The new institution's stated plan was simple to say and hard to do: turn an infrastructure lender into a retail bank.

The Problem It Inherited

An infrastructure book is a poor foundation for a modern bank. The loans are large, so a single default hurts. The tenures are long, so problems surface slowly. And the funding model of the old institution leaned heavily on expensive borrowings rather than cheap customer deposits.

Retail lending is the opposite: many small loans, diversified risk, shorter tenures, and — crucially — a customer relationship that can be deepened over time. Capital First brought exactly that capability, including underwriting for customers traditional banks often overlooked, such as small businesses and first-time borrowers.

Shrinking to Grow

The most interesting part of the strategy is what the bank chose to run down. Rather than keep the infrastructure book and add retail on top, it deliberately let the legacy wholesale portfolio shrink while growing retail, rural and small-business lending.

This is uncomfortable. For several years the bank's headline numbers carried the cost of old legacy assets while the new retail engine was still being built. Investors had to accept a long transition in exchange for a better shape at the end.

On the funding side, the bank did something similar to what Kotak did years earlier: priced savings accounts attractively to pull in retail deposits and reduce its dependence on costly borrowings. It's an expensive way to buy a deposit base — but it's the only way a bank without an inherited liability franchise can get one.

Customer-Facing Choices as Strategy

IDFC FIRST has leaned visibly into customer-friendly positioning: zero-fee savings account services on many common transactions, lifetime-free credit cards, and a public emphasis on transparent pricing.

These aren't just marketing. For a bank that needs to win customers from established incumbents, a clear "no hidden fees" promise is one of the few differentiators that ordinary customers notice and remember. It also sets an expectation the bank must keep meeting, which is a real constraint.

The credit card business, in particular, has been an aggressive growth area — and a double-edged one. Cards are high-yield products that build engagement, but unsecured credit is where losses show up first when the cycle turns.

Where the Model Strains

Cost of transformation. Paying higher deposit rates, building branches, and growing a retail franchise from scratch is expensive. Operating costs relative to income have been high compared with established peers, and the payoff depends on the franchise maturing.

Unsecured credit risk. Growth in cards and microfinance-adjacent lending improves yields, but those segments are the most sensitive to stress. Rising delinquencies in parts of the market in recent years have shown how fast that can bite.

Execution over years. A transformation this long depends on consistent leadership and investor patience. The bank's 2024 merger with its parent holding structure simplified the organisation, but the core test is still the same one: can retail profitability outgrow the cost of building it?

The Actual Lesson

IDFC FIRST Bank is a case study in the difference between adding a strategy and replacing one. Adding retail to an infrastructure lender would have been easier and slower. Deliberately running down the old book was harder and more honest about what the bank needed to become.

For any lender, the takeaway is that the shape of your balance sheet is your strategy. Changing it takes years, it costs money up front, and it only pays off if you're willing to accept looking worse before you look better.
