In 2019, the Indian government announced the mega-merger of ten public sector banks into four. It was the most ambitious consolidation in Indian banking history, and the stated goal was straightforward: create fewer, stronger, more efficient banks that could compete with the private sector and serve India’s growing economy.

Seven years later, it’s fair to ask: did it work? And are more mergers on the way?

What the Mergers Were Supposed to Achieve

The logic behind consolidation was sound on paper. India had too many small, underperforming public sector banks. Many had overlapping branch networks, duplicated operations, and insufficient scale to invest in technology. NPAs (non-performing assets) were concentrated in smaller banks that lacked the balance sheet strength to absorb losses.

By merging smaller banks into larger ones, the government hoped to achieve economies of scale, reduce operational costs, improve capital adequacy, and create institutions large enough to fund major infrastructure and industrial projects.

The key mergers included the combination of Oriental Bank of Commerce and United Bank of India into Punjab National Bank, the merger of Syndicate Bank into Canara Bank, and the consolidation of Andhra Bank and Corporation Bank into Union Bank of India.

The Results So Far

The picture is mixed. On some metrics, consolidation has worked. The merged banks are larger and better capitalised. Their combined balance sheets are stronger, and they’ve been able to meet Basel III requirements more comfortably.

But on other metrics, the story is less encouraging.

Branch rationalisation has been slow. One of the main efficiency arguments for mergers was eliminating overlapping branches. In practice, closing branches in a democracy is politically fraught. According to a Business Standard analysis from late 2025, fewer than 15% of identified redundant branches had been closed across the merged entities.

Technology integration remains incomplete. Each legacy bank had its own core banking system, its own processes, and its own IT infrastructure. Integrating these systems is enormously complex and expensive. Punjab National Bank, formed from three separate entities, was still running dual systems for some functions as recently as mid-2025.

Staff morale and culture clashes persist. Bank employees from merged entities often retain loyalty to their original institution. Seniority disputes, transfer anxieties, and cultural differences between organisations have created friction that affects service delivery. The All India Bank Employees’ Association has been vocal about staff welfare issues resulting from mergers.

NPA ratios haven’t improved dramatically. While gross NPA ratios have declined across the sector, much of that improvement comes from write-offs and recoveries through the Insolvency and Bankruptcy Code rather than from merger-related efficiencies. The underlying asset quality discipline hasn’t materially changed in most merged banks.

Are More Mergers Coming?

Speculation has been building throughout 2025 and into 2026 about a second round of consolidation. The most commonly discussed possibility is reducing the number of public sector banks from the current twelve to five or six.

Several factors make this likely:

Political will exists. The current government has shown it’s willing to push through banking reforms despite political costs. The 2019 mergers faced significant opposition from unions and were implemented anyway.

Private sector competition is intensifying. HDFC Bank, ICICI Bank, Kotak Mahindra, and Axis Bank continue to gain market share. Public sector banks need greater scale and efficiency to compete, particularly on technology and digital services.

Capital constraints. The government has limited fiscal space to continue recapitalising multiple banks. Fewer, larger banks would require less total capital infusion.

However, there are strong arguments against rushing into further consolidation. The 2019 mergers haven’t fully delivered on their promises yet. Layering additional mergers on top of incomplete integrations risks creating larger problems rather than solving existing ones.

The Reserve Bank of India has been cautious in its public commentary, neither endorsing nor discouraging further mergers. Governor Malhotra’s February 2026 remarks emphasised that any future consolidation should be “driven by strategic fit rather than arithmetic convenience” — a not-so-subtle message that size alone isn’t the answer.

What Would Make Consolidation Work Better?

Looking at successful banking mergers internationally — and the less successful ones in India — a few lessons emerge:

Technology integration must be prioritised. Running dual systems for years after a merger is unacceptable. A clear, funded technology migration plan with realistic timelines should be a prerequisite for any future merger.

Human resources matter. Staff from merged entities need clarity about their roles, career paths, and terms. The uncertainty that followed the 2019 mergers damaged morale and customer service.

Customer experience must improve, not decline. Several merged banks saw service deterioration in the 12-18 months following merger as systems and processes were in flux. Customers don’t care about structural efficiency. They care about whether their branch is open, their app works, and their problems get resolved.

Clean up NPAs first. Merging a bank with 8% gross NPAs into one with 4% doesn’t fix either bank’s asset quality problem. It just creates a larger bank with a 6% NPA ratio.

The Bigger Question

The consolidation debate is really a proxy for a larger question: what role should public sector banks play in India’s future? If they’re primarily instruments of government policy — vehicles for priority sector lending, financial inclusion, and infrastructure financing — then their structure matters less than their mandate.

If they’re supposed to compete with private banks on commercial terms, then consolidation is necessary but not sufficient. They also need governance reforms, technology investment, operational freedom, and the ability to attract and retain talent.

India’s banking system is at a crossroads. The mergers of 2019 were a step, but they weren’t a destination. What happens next will determine whether public sector banks remain relevant players in an increasingly digital, private-sector-driven financial landscape.
