Public sector banks have been in the market spotlight for the past two years. The Nifty PSU Bank Index has jumped nearly 500% over the past five years, an exceptional surge for any sectoral index.
Investors are now questioning whether this rally is driven by fundamental strength in the banking sector or by the government’s potential new merger plans. Finance Minister Nirmala Sitharaman recently stated that India needs large, world-class banks, and the next phase of consolidation among PSU banks is already underway.
Let us understand whether mergers can keep the PSU bank rally going.
What’s Happening?
India’s public sector banking structure is once again moving toward a major transformation. In an interview with CNBC-TV18, Finance Minister Nirmala Sitharaman confirmed that the next phase of PSU bank consolidation has begun.
This time, the expectation is that the government will go beyond mergers and undertake a deeper review of ownership, governance, and operational efficiency, ensuring the long-term strength and sustainability of public sector banks.
Since 2017, India has witnessed six major phases of banking mergers. Between 2017 and 2020, the government merged 10 banks into 4 large entities, reducing the total number of PSU banks from 27 to 12. A significant milestone was achieved when the country’s largest public sector lender, the State Bank of India (SBI), merged six of its associate banks, including State Bank of Bikaner & Jaipur, State Bank of Hyderabad, State Bank of Patiala, State Bank of Mysore, State Bank of Travancore, and Bharatiya Mahila Bank.
Data-Driven Growth and the Changing Face of India’s Banking Sector
According to Mint, PSU banks collectively reported losses of around Rs 26,000 crore in FY20, but by FY24, their consolidated profit surged to Rs 1.4 lakh crore, and is expected to reach Rs 1.7 lakh crore in FY25. The NPA (Non-Performing Assets) ratio, which was once in double digits, has now sharply declined to 2.8%. In FY25, loan growth for PSU banks stood at 12%, outpacing private banks’ 10% growth.
Public sector banks have recaptured nearly 58% of the total credit share. Reports further highlight that PSU banks’ Return on Equity (ROE) now stands at an impressive 18–19%, narrowing the gap with private peers.
The turnaround has been supported by government and RBI initiatives, including liquidity support measures, relaxation in lending norms, and credit line access to NBFCs. The RBI’s CRR cut, which released Rs 2.5 lakh crore into the system, along with 22 other policy reforms, has further boosted the sector’s strong growth momentum.
Not Just Mergers, Deep Transformation is Essential
There is growing discussion around the next wave of PSU bank consolidation, but the first and most important question is: how will this process move forward?
One possible approach is that the government could merge the remaining unamalgamated banks, such as UCO Bank, Central Bank of India, Indian Overseas Bank (IOB), and Bank of Maharashtra (BoM), with Bank of India (BoI). Bank of India already has a book size of over Rs 6 trillion, while the other four banks have a deposit base between Rs 3 and 3.6 trillion. However, this move is not as simple as it sounds.
The biggest challenge in any banking merger is technological integration. Aligning core banking systems operating on different platforms significantly increases time, cost, and operational risk.
Another approach could be to merge smaller banks with larger PSU banks in a way that ensures both scale and technological or regional compatibility. For example, UCO Bank and Central Bank could merge with PNB, Bank of India with Union Bank, and IOB with Indian Bank.
What’s in it for Investors?
PSU bank stocks have surged nearly 500% over the past three years, but investing merely by chasing the rally can be risky. Investment decisions should be based on financial health, asset quality, ROE, and progress in digital and governance transformation. The government’s merger decisions have a direct impact on these banks’ stock performance. Meanwhile, policy changes by the RBI and the government, such as potential CRR cuts, loan growth initiatives, and a possible hike in FDI limit, continue to strengthen investor confidence.
If we analyse the YTD returns, the Nifty PSU Bank Index has delivered a 26.94% return, while the Nifty and Sensex have returned only 9.45% and 8.11%, respectively. This makes the Nifty PSU Bank Index one of the top-performing indices of 2025 so far.
What’s Next?
The government’s new consolidation focus on PSU banks is not merely a domestic reform but a strategic move to position Indian banking in the league of global competitors. This step aligns with the country’s long-term vision of ‘Viksit Bharat 2047’.
India aims to have at least two Indian banks among the world’s top 20 global banks in the coming years. This ambition is not just about prestige; it is about capability. Over the next two decades, India will require massive financing for projects like green energy corridors, smart city networks, high-tech manufacturing, and digital infrastructure. To meet these needs, the banking system must scale up enough to finance this transformation from its own resources. Hence, the consolidation of PSU banks marks a decisive step toward preparing them for the economy of the future.
