Union Bank of India Ratings Reaffirmed at CARE AAA

Infrastructure Bonds: Rs 10,000 crore (Reaffirmed); Tier 2 Bonds: Rs 2,200 crore (Reaffirmed).

Reader Takeaway: Strong capital buffers and government backing support the rating, despite moderate CASA ratios compared to peers.

What just happened

CARE Ratings Limited has officially reaffirmed the 'CARE AAA; Stable' rating for Union Bank of India's long-term infrastructure and Tier 2 bonds. The agency simultaneously withdrew the rating for the bank's perpetual bonds, as no issuance is currently outstanding under that specific instrument.

Why this matters

A 'CARE AAA' rating signifies the highest degree of safety regarding the timely servicing of financial obligations. For retail investors and debt holders, this reaffirmation serves as a signal of institutional stability, reflecting the bank’s ability to manage its balance sheet amid evolving credit conditions.

The backstory

The bank has seen a multi-year improvement in asset quality, a trend that continues to be a central pillar of its credit profile. As of June 30, 2026, the bank reported a robust Capital Adequacy Ratio (CAR) of 18.46%, with a Tier I ratio of 16.38%, positioning it comfortably above regulatory requirements.

Risks to watch

While the outlook is stable, the bank faces pressure regarding its CASA (Current Account Savings Account) ratio, which remains lower than several of its public sector bank peers. Improving this deposit mix is vital for future profitability and cost-of-funds management. Additionally, the bank must remain vigilant against systemic operational risks, including cybersecurity threats.

What to track next

Investors should continue to monitor the bank’s ability to grow its deposit base and maintain its asset quality trajectory. Furthermore, given the majority ownership by the Government of India, any changes in government policy regarding the capital structure of public sector banks remain a primary long-term sensitivity factor.
