Indian bank stocks experienced a significant downturn on September 28, 2026, with both public and private sector lenders recording sharp declines. The Nifty Bank index fell by 1.99%, while the BSE PSU Bank index dropped 3.25%, reflecting broad market concerns.
Among the hardest hit were private lender YES Bank, which saw its shares fall 6.18% to Rs 21.18. Public sector banks also faced substantial losses, with Bank of India declining 5.44% to Rs 130.45. Other prominent lenders like Bank of Maharashtra, Union Bank of India, Punjab National Bank, Canara Bank, and State Bank of India registered falls ranging from 2.10% to 4.66%. Major private banks such as HDFC Bank, ICICI Bank, RBL Bank, and AU Small Finance Bank also saw declines of up to 2.3%.
Key Factors Behind the Sell-Off
The primary drivers for the market's negative sentiment were the increasing probability of interest rate hikes by the Reserve Bank of India (RBI) and fears that rising bond yields would negatively impact banks' treasury income. Nomura highlighted that the RBI's monetary policy is at a crucial juncture, noting that while India has avoided rate hikes seen in other Asian economies, elevated oil prices, surging food costs, and Federal Reserve rate hikes are pushing the RBI towards an inflection point. Markets are currently anticipating approximately 125 basis points of rate hikes over the next year.
Siddhartha Khemka, Head of Research for Wealth Management at Motilal Oswal Financial Services, underscored concerns about a potential rate hike during the RBI's October policy meeting due to persistent inflation risks. He pointed out that the 10-year Indian government bond yield climbed to 7.12%, its highest level since May 2026, while the US 10-year Treasury yield also rose to around 5.21%, further tightening financial conditions.
Additionally, deficient monsoon rains have hinted at a lower output for both kharif (summer) and rabi (winter) crops, which is expected to dampen rural consumption and further weigh on economic sentiment.
Technical Indicators Signal Continued Weakness
Beyond fundamental factors, technical analysis also indicated a bearish trend for bank stocks. Vatsal Bhuva, Technical Analyst at LKP Securities, observed that the Nifty Bank closed with a long bearish candlestick on the daily chart, slipping decisively below its 100-day Simple Moving Average on the weekly chart, signaling ongoing weakness.
However, Bhuva noted that the Relative Strength Index (RSI) has entered the oversold zone, potentially triggering a short-term bounce in upcoming sessions. He cautioned that any such recovery should be viewed as an an oversold bounce rather than a trend reversal, advising traders to adopt a "sell-on-rise" strategy. Immediate support for the Nifty Bank is placed at 54,000, with 55,200 acting as a crucial resistance level.
Sudeep Shah, Head of Technical and Derivatives Research at SBI Securities, reinforced the bearish outlook, stating that the Nifty Bank continues to trade below its key short and long-term moving averages. Momentum indicators also remain weak, with the daily RSI dropping to 30.22, its lowest reading since April 2026, underscoring strong downside momentum. Shah predicts that the zone of 55,000-55,100 will serve as immediate resistance, and as long as the index stays below 55,100, the bearish bias is expected to persist, potentially pushing the index towards 53,900 and then 53,400 in the short term.
