2025 has been quite the rollercoaster of a year for the Nifty Bank index. It started with a slide at the beginning of the year, followed by a recovery in March-April. Thus began a rally till June, after which there was a period of consolidation. But since the start of October, the index has seen upward movement of nearly 7%.

But what has been the cause of all this movement? Let’s find out.

Which Stocks Led the March Recovery and Spring Rally?

The short answer is HDFC Bank and ICICI Bank.

HDFC Bank regained much of its lost ground all through April and May, gaining more than 12% by the end of July and reaching a lifetime high. This was on the back of a good Q4 showing for FY25. It reported a rise in standalone net profit, interest income, and an improvement in asset quality.

Similarly, ICICI Bank also reported a healthy Q4, helping it record a new 52-week high in April. India’s second-largest private lender saw its profit jump more than 15% year-on-year, while net interest income also increased.

With both the market heavyweights leading the way, the Nifty Bank share price rose approximately 18% from mid-March to mid-July. It’s clear that when these names move together, the index follows.

Which names fuelled the mid-year momentum?

RBL Bank is another name, gaining more than 100% year-to-date as of November 2025. From a position of prolonged underperformance, it produced a staggering turnaround and earned its multibagger status. While it’s still significantly lower than its lifetime high, RBL Bank share price is at its highest since March 2020 at Rs. 328+. There’s been a rapid improvement in asset quality, while news of a potential takeover from the Dubai-based Emirates NBD has further reinforced the rally.

May also saw a remarkable spike from Yes Bank. Sumitomo Mitsui Banking Corporation (SMBC) acquired a 20% stake in the company, buying out SBI’s share in the process. They increased their stake further to 24.99% - the maximum permissible limit- and are open to increasing their stake if they get regulatory approval. Yes Bank’s Q2FY26 result showed an increase in standalone net profit and reduced interest expenses. However, the net interest income fell 3%, while total income for the quarter was also down, indicating a competitive landscape.

The high-profile stake sale to a foreign entity not only lifted Yes Bank’s share price but also showed optimism towards the sector.

How did these moves play into the September pullback?

September witnessed some profit booking, but the index largely hovered around 53,000-54,500. Foreign portfolio investors (FPIs) went on a selling spree, bringing even the benchmark indexes down. Upbeat U.S. GDP data saw chances of rate cuts disappear. And considering the earnings season was just around the corner, investors remained on the sidelines.

But the banking leaders buffeted the sideways movement of the index, and with good reason.

So which banks truly drove the index?

HDFC Bank – reported a 10.8% increase in standalone net profit, while net interest income (NII) also grew nearly 5% on their Q2FY26 report card. On the announcement, HDFC Bank’s share price rose about 12% YTD, having risen 5% in the previous 6 months.

ICICI Bank – Strong heavyweight momentum in the year continued towards the end of the second quarter. It reported a 5% YoY rise in standalone net profit for Q2, while provisions for bad loans and other losses fell 26%, helping the bottom line. NII grew above 7%, and deposits rose as well. However, because of single-digit growth and less than anticipated income, the stock has seen profit booking, with significant selloff amongst FPIs in October.

RBL Bank – RBL Bank’s momentum has continued despite poorer Q2 results. Net profit and NII were down 20% and 4%, respectively. However, confirmation of the stake sale to Emirates NBD has kept buyers interested.

Kotak Mahindra – The biggest laggard in the Nifty 50 and Bank indexes-in the first quarter-Kotak Mahindra missed quarterly profit estimates while asset quality pains continued. Its NPA ratio worsened, and NII contracted too.

Axis Bank – Another major bank responsible for the first quarter slump in Nifty Bank, with disappointing results and concerns of declining asset quality.

Yes Bank – Good quarterly results, coupled with the sector’s largest cross-border acquisition, have marked a significant turnaround for the beleaguered bank.

The positive financial performance of the heavyweights, coupled with investments from overseas in other private banks, has led to the upward movement of Nifty Bank. GST reforms have boosted lending growth.

Meanwhile, in the short-term, AU Small Finance Bank, Indus Ind, Canara Bank, PNB, Federal Bank, and IDFC Bank have all contributed significantly to the rally in Nifty Bank. Buoyed by positive earnings outcomes and valuation comfort, the sluggishness of H1 is truly over.

The price-to-book ratio is still below its 5-year average, suggesting there’s more ground to cover. Government proposals to merge several PSUs into a larger entity have also resonated positively with investors.

Conclusion

With steady earnings from the leaders and mergers and acquisitions of stressed units, Nifty Bank has reached its lifetime high, with room on the runway. The trend is firmly bullish as we head into the next year. Investors should keep an eye on the news and conduct fundamental research before investing.
