How should HDFC Bank turn merged HDFC Ltd home-loan customers into digital, multi-product banking customers?

Introduction

On 1 July 2023 HDFC Ltd, India's largest housing finance company, merged into HDFC Bank. The bank gained a large mortgage book and lakhs of home-loan customers, many of whom had never held an HDFC Bank savings account, card or investment. Management has repeatedly said that a key benefit of the merger is the ability to offer these customers the bank's full product range. Yet mortgage customers are historically low-engagement: they interact once a month through an EMI. The prompt asks: how should HDFC Bank's digital product strategy turn the legacy HDFC Ltd home-loan base into multi-product banking customers?

Key business objectives:

1. Grow low-cost deposits, since the merger left the bank with a high credit-deposit ratio that management has been working to bring down
2. Cross-sell cards, insurance, investments and personal loans to a creditworthy base
3. Increase digital engagement of home-loan customers
4. Do this without mis-selling or damaging trust

Steps:

1. Clarify strategic goals
2. Analyse market and competition
3. Define vision and roadmap
4. Prioritise initiatives
5. Plan execution
6. Set KPIs
7. Manage risks

Step 1

Clarify the Strategic Goals (3-4 minutes)

• Which outcome matters most: deposits, fee income, or product-per-customer?

Why it matters: Deposit mobilisation suggests salary and savings account moves; fee income suggests insurance and cards. Expected answer: Deposits are the priority, followed by product depth. Impact on approach: The first product to sell is a savings account that the EMI is paid from.

• What share of home-loan customers already hold an HDFC Bank account?

Why it matters: Defines the size of the white space. Expected answer: Roughly 30–40% of legacy HDFC Ltd borrowers had no bank relationship at the time of the merger (illustrative). Impact on approach: The "no account yet" segment is the main target.

• What channels reach these customers today?

Why it matters: Mortgage customers rarely use banking apps. Expected answer: EMI reminders, annual interest certificates, a separate home-loan portal and branches that were HDFC Ltd offices. Impact on approach: We need to bring them into the HDFC Bank App journey.

Key strategic assumptions:

1. Home-loan borrowers are prime customers: verified income, assets and long tenures.
2. Trust and relevance, not product availability, are the barriers.
3. The first moment of value must be tied to their home loan.
