IDFC First Bank has made an impressive mark by entering the list of India's 10 most valuable listed banks, with a valuation of approximately Rs 65,325 crore as of September 4. This achievement comes as the bank's shares hit a record high of Rs 98.99 each, continuing a four-day trading session rally. In the banking sector, it leads the pack with a remarkable 67 per cent surge in its stock price this year, surpassing all other listed banks, whether private or state-run. This impressive performance can be attributed to the impending merger with IDFC and its inclusion in the MSCI Global Standard Index on September 1, which is expected to attract $170-180 million in investments.

However, while many investors are enthusiastic about this achievement, some analysts are closely monitoring the bank's performance. Despite a strong showing in various financial metrics, there is curiosity about the sustainability of this momentum. CEO Vaidyanathan, who has previously emphasized growth, appears to be shifting towards a more balanced approach between growth and profitability.

IDFC First Bank exhibits strong financial indicators, including a robust net interest margin (NIM) and a solid growth profile. Despite market challenges, the bank has maintained healthy asset quality. However, its Return on Assets (RoA) and Return on Equity (RoE) have been impacted by a high cost-to-income ratio. The bank reported an impressive nearly 36 per cent year-on-year increase in net interest income for the June quarter, with other income also surging by 49 per cent. Its net profit advanced over 61 per cent, while provisions increased by 55 per cent compared to the previous year. Operating expenses were up 37 per cent. The bank's RoA and RoE improved to 1.25 per cent and 11.78 per cent from 0.97 per cent and 8.96 per cent, respectively, but its cost-to-income ratio remained elevated at 71 per cent during the June quarter for more than two years.

This rise in operating expenses and provisioning has raised concerns among investors about the bank's ability to reward them. The positive outlook for the bank depends on anticipated improvements in return on equity and return on assets. Analysts expect the bank's cost-to-income ratio to begin moderating to 55 per cent in the next quarter.

The bank's management remains optimistic about its ability to achieve enhanced growth in its loan book while continually improving asset quality. Analysts anticipate the bank's cost-to-income ratio will begin to moderate to 55 per cent next quarter.

IDFC First Bank reported a 25 per cent increase in advances from the previous year, while deposits surged by 44 per cent. The bank's advance growth ranked third highest among all listed banks, while its deposit growth was the most significant among them. The bank's CASA ratio stood at 46.47 per cent, higher than larger lenders like State Bank of India, Axis Bank, HDFC Bank, and ICICI Bank.

Analysts have noted significant improvements in the lender's retail business, with a positive RoA of approximately 1.15 per cent for FY23, compared to negative figures for FY22 and FY21. They have also observed improved asset quality in terms of customer quality at onboarding and across vintage, enhancing confidence in the sustainable low credit cost trend.

The future looks promising for the bank, especially in the public sector, where there is increasing momentum. With a track record of profitability, the bank is well-positioned to capitalize on these opportunities.

In conclusion, IDFC First Bank's entry into the top 10 most valuable listed banks in India is a significant milestone, driven by strong financial performance and strategic moves. While challenges persist, the bank's management and analysts remain optimistic about its future growth and profitability prospects.
