Bond default explained: Impact on retail investors, risks, and lessons for smarter investments

A bond default occurs when an issuer fails to pay interest or repay principal to the bondholders. Such a default can cause immediate liquidity problems for investors across the country. The recent default by the state-run telecom organisation MTNL on its sovereign debt, i.e., guaranteed bonds, has again brought this issue into sharp focus. It becomes extremely important for retail investors to understand the reasons behind such defaults, even more so if they are looking to expand investments in the fixed income sector.

Bond defaults disrupt investor expectations of potentially safe-looking income. It can cause severe reversal of fortunes and capital loss, especially in corporate bonds without government backing.

Retail investors in such cases may be forced to face illiquidity and uncertainty over recovery timelines. Still, for example, in MTNL’s case, a sovereign guarantee simply means that the government is responsible for honouring bond payments if MTNL defaults.

Such guarantees provide a safety net in government securities, unlike corporate bonds. This feature highlights the risks associated with corporate bonds and emphasises the importance of proper due diligence before going ahead with any particular bond for long-term investments.

MTNL failed to fund the escrow account needed for the August 24, 2025, interest payment on its MTNL Bond Series VIIIB (7.61%), citing cash flow shortages and limitations under a tri-partite agreement with the Department of Telecommunications and trustees.

Given that this bond default signals financial stress and complications, the government guarantee will ensure that the bondholders receive payments through invocation by the debenture trustee. Currently, MTNL’s total debt obligation stands at ₹34,577 crore, with ₹8,659 crore in bank loan defaults and ₹24,071 crore in sovereign-guaranteed bonds.

When a bond default occurs, bondholders may experience loss of expected income and a decline in bond market value. Defaults can result in panic and liquidity issues, thus forcing investors to hold potentially distressed securities longer than planned.

This uncertainty and unpredictability with payments can disrupt portfolio stability, performance, and cash flow planning. Retail investors must be prepared for such risks by ensuring appropriate diversification and maintaining a mix of investment-grade and government bonds for steady performance.

Consistent improvements and initiatives by SEBI and the RBI, including the Retail Direct scheme, improve market access and transparency for retail investors. Still, liquidity issues and credit risks persist in corporate bonds.

Therefore, as a prudent investor, you should clearly understand the pros and cons of bond investments and take appropriate steps to educate yourself. Discussing your doubts with regard to bond performance, defaults, and future return potential with certified financial planners before opting for any particular bond can be the most prudent way to go ahead with your bond investment planning.
