The Indian stock market witnessed a historic milestone as the Bank Nifty soared to an all-time high, breaching the 48,000 mark on December 15, led by a late-hour rally in HDFC Bank shares. Simultaneously, the broader Nifty 50 index also registered a substantial gain of 1.42 percent on the same day.

HDFC Bank's Influence on the Surge

HDFC Bank, accounting for an 11 percent weightage in the Nifty 50 and a significant 30 percent in the Bank Nifty index, exhibited a remarkable surge in its closing price at Rs 1656.55, marking a 0.39 percent increase. This upsurge in HDFC Bank directly reflected on the Nifty 50 and Bank Nifty indices due to its significant weighting in these benchmarks.

FTSE Rebalance: A Catalyst for Inflows

The striking surge in HDFC Bank's stock price was attributed to its prominent role in the FTSE (Financial Times Stock Exchange) rebalance. As a result of this rebalance, passive index mutual funds that track the FTSE indices are mandated to adjust their portfolios, thus leading to substantial capital inflows into the included stocks.

Estimates by Nuvama Research and IIFL anticipate significant inflows into HDFC Bank, projected at around $547 million and $451 million, respectively, owing to the FTSE rebalancing.

Analysts Perspectives and Future Projections

Market experts and analysts are optimistic about the Bank Nifty's future trajectory following this surge:

• Kunal Shah from LKP Securities predicts a potential upward surge for the Bank Nifty, envisioning it reaching the 50,000 mark. He views any pullbacks toward support levels as lucrative buying opportunities.
• Ajit Mishra of Religare Broking advises aligning with the ongoing outperformance of banking and IT majors, suggesting a cautious approach against contrarian positions.
• Chandan Taparia of Motilal Oswal Financial Services points out that Bank Nifty formed a bullish candle on the daily and weekly frames, indicating potential support-based buying and further upward momentum.

Market Resilience Against Prior Challenges

Previously, banking stocks experienced pressure after the Reserve Bank of India (RBI) increased risk weightage on consumer loans, causing a temporary setback. However, the recent surge marks a significant comeback, demonstrating the market's resilience and its ability to overcome transient challenges.

The recent surge in the Bank Nifty, driven by HDFC Bank's late-hour upsurge amidst the FTSE rebalance, signifies a monumental moment for the Indian stock market. Market observers and analysts foresee a promising future trajectory for banking indices, affirming potential growth prospects and sustained market resilience.
