The Nifty PSU Bank index rose 2% to hit a new record high of 8,330.75, as shares of Bank of Baroda, State Bank of India, Indian Bank, Bank of India and Canara Bank hit fresh 52-week highs in today’s trade.

The rise in share prices of these public sector banks is due to two primary reasons: strong Q2 performances, and Sebi’s recent announcement of new rules for the Nifty Bank index.

PSU Banks’ Q2 performance –

Leading the Nifty PSU Bank index was Bank of Baroda, which rose 4.53%, followed by Indian Bank, which was up by 2.52%. A common thread that has boosted investor sentiment in these stocks is the improvement in net asset quality or NPAs.

Bank of Baroda recorded an 8% decline in its net profit, but saw improvement in asset quality. Net interest margin (NIM) declined by 15 basis points to 2.96% in Q2FY26 from 3.11% a year ago. The lender’s net interest income (NII) rose by 2.7% to ₹11,954 crore, versus ₹11,637 crore in Q2FY25.

Indian Bank posted a core income rise of 6% and its net profit also grew by 11.5% on a year-on-year basis. Its standalone revenue also rose by 7.35% to ₹19,076.57 crore YoY, while NII rose by 6%. Improvement in asset quality was also noticed, with reductions in both gross and Net NPAs.

Bank of India also posted positive Q2 results in October, with a rise of 8% YoY in net profits to ₹2,555 crore. Global and Domestic NIM for Q2FY26 stood at 2.41% and 2.66% respectively. BOI also recorded an improvement in NPAs, with gross NPAs improving by 187 bps and net NPA ratio by 29 bps YoY.

Canara Bank also posted its Q2 earnings, with a 19% YoY rise in net profit to ₹4,773.96 crore. The bank’s net interest income (NII) declined 2% to ₹9,141 crore, while other income grew 41.6% on a year-on-year basis. NIM marginally declined to 2.52% in Q2, versus 2.55% in the previous quarter.

State Bank of India will be announcing their Q2 results today.

What are the new rules by Sebi for Nifty Bank?
