MTNL bank defaults hit ₹9,263 crore; debt ₹36,314 crore

What MTNL disclosed and why it matters

Mahanagar Telephone Nigam Limited (MTNL) has reported continued defaults on principal instalments and interest payments to a consortium of seven public sector banks, as per disclosures made under SEBI’s default reporting requirements. Across different filings and reference dates cited in the disclosures, the reported default amounts have varied, reflecting updates in outstanding balances, overdue components, and reporting cut-offs. One disclosure cited defaults amounting to ₹9,263 crore, with Union Bank of India (UBI) the single largest creditor. Separately, the information provided also states MTNL’s total debt has reached ₹36,314 crore. The updates are important for investors because they document persistent non-payment status, the lenders involved, and the dates when facilities were classified as non-performing assets (NPAs).

SEBI framework behind the default reporting

MTNL’s filings refer to SEBI/HO/CFD/CMD1/CIR/P/2019/140 dated 21 November 2019, which requires listed entities to disclose loan defaults. In the disclosures described here, MTNL reported defaults related to both principal and interest obligations. The company named seven lenders: Union Bank of India, Bank of India, Punjab National Bank, State Bank of India, UCO Bank, Punjab and Sind Bank, and Indian Overseas Bank. The filings also specify the date of disclosure, and separately list the dates when the accounts were classified as NPAs by respective lenders. These disclosures do not, by themselves, describe a resolution plan, but they formally record the default status and the composition of overdue amounts.

Bank-wise defaults as of March 31, 2026

MTNL reported total outstanding obligations of ₹9,263 crore to these seven banks as of March 31, 2026, along with a split between principal, overdue interest, and overdue principal. The same dataset shows UBI as the largest exposure, followed by Indian Overseas Bank (IOB). The NPA dates for the facilities range from August 12, 2024 to February 3, 2025. The table below captures the bank-wise figures provided.

How the reported totals shifted across filings

The information provided includes multiple snapshots of MTNL’s reported bank defaults across different dates. One set of numbers said MTNL disclosed defaults of ₹9,115.65 crore as of January 31, 2026. Another filing described a “current default amount” of ₹8,881.48 crore, comprising ₹7,794.34 crore of overdue principal and ₹1,087.14 crore of overdue interest. There is also a separate statement that the bank loan default stood at ₹8,659 crore at the end of July, with bank-wise default amounts listed for the same set of lenders. In addition, one disclosure refers to defaults amounting to ₹8,585 crore from these seven public sector banks.

July 31, 2026 disclosure in rupee-million terms

One disclosure explicitly states that MTNL defaulted on principal and interest payments amounting to INR 95,746.1 million as of July 31, 2026. Converting this to a single unit for easier comparison, INR 95,746.1 million equals ₹9,574.61 crore. In that disclosure, UBI’s figures were stated as outstanding INR 41,787.4 million (₹4,178.74 crore), principal INR 33,345.7 million (₹3,334.57 crore), and overdue interest INR 8,441.7 million (₹844.17 crore). Similar rupee-million figures were provided for Bank of India, Punjab National Bank, and State Bank of India in the same section. These figures are separate from the March 31, 2026 table and indicate that the company has continued to report defaults over time.

Timeline of key default snapshots cited

The following table summarises the different default totals and reference dates included in the provided information. These are not presented as a single reconciled series, but as distinct disclosures or news summaries tied to specific reporting cut-offs.

Total debt at ₹36,314 crore in the latest context

Alongside bank-default disclosures, the information provided also states MTNL’s total debt has reached ₹36,314 crore. The data shared here does not break this total debt into components for the ₹36,314 crore figure, but it is presented as the broader leverage context in which the bank defaults are being reported. In another section of the provided material, MTNL’s debt composition at an earlier date was described with categories such as bank loans, sovereign guarantee bonds, and a Department of Telecommunications (DoT) loan for paying sovereign guarantee bond interest. While that earlier breakdown is not the same as the ₹36,314 crore figure, it signals that MTNL’s obligations extend beyond only bank facilities.

Market impact: what the disclosures change for investors

From a market perspective, the most concrete takeaway is the persistence of default status across the same lender group, and the fact that NPA classification dates are already in place for each bank exposure. The disclosures quantify overdue principal and overdue interest, which matters when investors evaluate the extent of past-due obligations rather than only total outstanding. The repeated updates also indicate that the company continues to make SEBI-mandated default filings as the numbers change over time. For bank stakeholders, the NPA dates spanning August 2024 to February 2025 establish the timeline of stress, while the outstanding amounts show where exposures are concentrated, especially with UBI and IOB.

Analysis: why the UBI exposure stands out

UBI being the largest creditor is a consistent feature across the data provided, including the March 31, 2026 table and the rupee-million disclosure where UBI’s outstanding is the highest among named lenders. The bank-wise split into principal and interest also shows that the overdue interest component, while smaller than principal, is still material in absolute terms. The presence of multiple filings with different totals highlights a reporting reality investors should track carefully: totals may shift with time, but the underlying issue is continuous default reporting across several periods. The data also shows that the default narrative is not limited to one lender, but spread across seven public-sector banks.

What to watch next

The next concrete datapoints to monitor are MTNL’s subsequent exchange disclosures for updated default totals, any changes in lender classification or overdue composition, and any further SEBI-compliant default statements tied to new cut-off dates. Investors will also track whether MTNL provides additional clarity on how its reported total debt of ₹36,314 crore relates to bank borrowings versus other liabilities. For now, the filings cited here document ongoing non-payment of principal and interest obligations and provide bank-wise exposure details and NPA dates across the consortium.
