Mahanagar Telephone Nigam Limited Defaults on ₹9,574 Crore

Mahanagar Telephone Nigam Limited reported principal and interest payment defaults of ₹9,574.61 crore to seven public-sector banks as of July 31, 2026, with Union Bank of India accounting for ₹4,178.74 crore of the disclosed outstanding amount. The disclosure places the state-run telecom operator's bank liabilities and proposed asset monetisation under close focus.

What did MTNL disclose about its bank payment defaults?

MTNL disclosed that it had defaulted on principal instalments and interest obligations to Union Bank of India, Bank of India, Punjab National Bank, State Bank of India, UCO Bank, Punjab & Sind Bank, and Indian Overseas Bank. The company made the disclosure on July 31, 2026, under the applicable Securities and Exchange Board of India disclosure framework.

The total current default amount was ₹9,574.61 crore. This included ₹7,794.34 crore of principal and ₹1,780.27 crore of overdue interest, based on the lender-wise figures in the disclosure. The reported overdue principal was ₹2,195.72 crore, although no separate overdue-principal figure was stated for Indian Overseas Bank in the lender-wise data.

The defaults span loans that became non-performing assets from August 2024 to February 2025. Union Bank of India classified the account as an NPA on August 12, 2024, while Indian Overseas Bank's NPA date was February 3, 2025. The filings identify missed principal and interest payments, rather than a newly announced borrowing arrangement.

Which banks have the largest exposure to MTNL?

Union Bank of India has the largest disclosed exposure to MTNL at ₹4,178.74 crore, followed by Indian Overseas Bank at ₹2,712.89 crore. Together, these two lenders account for the largest portions of the ₹9,574.61 crore current default amount.

Bank of India reported outstanding dues of ₹1,260.92 crore, while Punjab National Bank's amount stood at ₹524.21 crore. State Bank of India had ₹391.71 crore outstanding, UCO Bank had ₹300.35 crore, and Punjab & Sind Bank had ₹205.79 crore.

The latest amount is higher than figures reported in earlier disclosures and news reports for 2025. MTNL had disclosed total bank and financial-institution borrowings of ₹8,659.09 crore in an August 2025 filing, while reports based on its June 2025 disclosure cited defaults of about ₹8,584.90 crore. The July 2026 disclosure provides the latest lender-wise position supplied in the source material.

What is the proposed ₹1,100 crore MTNL asset sale?

An inter-ministerial panel has recommended monetising MTNL's surplus land and building assets worth ₹1,100 crore. The proposal is awaiting approval from a body delegated by the Cabinet, according to the reported recommendation.

The proposal concerns non-core assets, rather than the company's telecom operations. Land and building monetisation can be relevant to a company with significant financial obligations because it concerns assets outside its primary business, but the available information does not state whether sale proceeds would be earmarked for a specific lender or repayment schedule.

The proposed asset value is substantially below the ₹9,574.61 crore aggregate bank default disclosed as of July 31, 2026. Therefore, the recommendation should be viewed as a distinct asset-monetisation measure within MTNL's wider financial position, not as a disclosed settlement of the listed bank obligations.

Why do MTNL's defaults matter to investors and lenders?

MTNL's disclosure matters because its missed payments involve seven major public-sector banks and a large principal component of ₹7,794.34 crore. The data show that the defaulted obligations are spread across multiple lenders, with the earliest NPA classification occurring in August 2024.

For lenders, the filing identifies the size of their reported outstanding exposure and the dates on which the accounts became NPAs. For investors, it provides a clearer view of the company's debt-servicing position and the concentration of its disclosed liabilities, particularly at Union Bank of India and Indian Overseas Bank.

The development is also relevant to the telecom sector because MTNL is a state-run operator and its financial disclosures are closely tracked alongside government-led measures involving its operations and assets. However, the source material does not disclose a fresh restructuring agreement, a repayment timetable, or lender-specific recovery terms.

How has MTNL's default position developed since 2024?

MTNL's disclosed NPA dates show that the payment stress emerged across the bank group over several months. Union Bank of India's account was classified as an NPA in August 2024, followed by Bank of India and Punjab National Bank in September 2024, State Bank of India and UCO Bank later that month, Punjab & Sind Bank in October 2024, and Indian Overseas Bank in February 2025.

Earlier disclosures had already indicated substantial unpaid principal and interest. The July 2026 filing shows a higher current default amount and a larger overdue-interest component than the 2025 figures cited in the source material. The factual record therefore points to continuing disclosed repayment stress across the same group of lenders.

The Cabinet-delegated body's decision on the recommended ₹1,100 crore sale of non-core land and buildings remains an unresolved item. Until an approval or implementation announcement is made, the asset proposal and the bank-default disclosures remain separate reported developments.

Conclusion

MTNL's July 31, 2026 disclosure records ₹9,574.61 crore of payment defaults across seven public-sector banks, led by ₹4,178.74 crore owed to Union Bank of India and ₹2,712.89 crore to Indian Overseas Bank. The figures underline the scale of principal and interest obligations that have remained unpaid since the accounts began turning into NPAs from August 2024.

The next item to watch is the decision of the Cabinet-delegated body on the inter-ministerial panel's recommendation to monetise ₹1,100 crore of MTNL's surplus land and buildings. Investors will also monitor future exchange disclosures for any changes in lender-wise defaults, repayment arrangements, or stated use of proceeds from asset monetisation.
