Bond Payment Details
| Parameter: | Details |
|---|---|
| Bond Series: | VI (INE153A08097) |
| Interest Rate: | 6.85% |
| Payment Due Date: | December 21, 2025 |
| Payment Type: | 10th Semi-Annual Interest |
| Escrow Account: | Bank of India |
| Funding Deadline: | 10 days before due date |
Structured Payment Framework
MTNL operates under a comprehensive Tri-Partite Agreement (TPA) framework involving multiple stakeholders. The structured payment mechanism requires MTNL to fund the semi-annual interest into the escrow account maintained with Bank of India at least 10 days before the payment due date.
| TPA Participants: | Role |
|---|---|
| MTNL: | Bond Issuer |
| Department of Telecommunications (DoT): | Government Representative |
| SBI CAP Trustee Company Limited: | Debenture Trustee |
| Bank of India: | Escrow Account Maintainer |
Sovereign Guarantee Protection
All bonds issued by MTNL carry sovereign guarantee from the Government of India, providing crucial protection for bondholders. Under this arrangement, if MTNL defaults on principal or interest payments, the debenture trustee can invoke the sovereign guarantee, obligating the Government of India to make the payment to MTNL.
Official Communication
In its regulatory filing dated December 11, 2025, MTNL informed the stock exchanges: "Due to insufficient funds MTNL could not fund the ESCROW Account maintained in Bank of India with the adequate amount." The company emphasized that the invocation of sovereign guarantee is based on Tripartite Agreements filed with BSE when the bonds were originally listed.
Financial Implications
This development highlights MTNL's ongoing financial challenges and its continued reliance on government support mechanisms. While the sovereign guarantee ensures bondholders will receive their payments, it underscores concerns about the company's operational cash flow generation and debt servicing capabilities. The situation may prompt closer scrutiny of MTNL's financial restructuring efforts and long-term viability in the competitive telecommunications sector.
