The short version
- Issuers may now have up to seventeen maturing ISINs per financial year.
- An extra six ISINs are allowed for specific capital gains tax bonds.
- Plain vanilla debt is capped at twelve ISINs with volume-based increases.
- Structured debt instruments are limited to five maturing ISINs per year.
- ESG and government-serviced bonds are excluded from these maturity calculations.
In short
This SEBI circular updates the rules for International Securities Identification Numbers (ISINs), which are unique codes used to identify specific debt securities. The change aims to make it easier for companies to raise funds and manage their debt maturity schedules.
What has changed
How it worked before
Previously, issuers were restricted to a lower number of maturing ISINs per financial year, which limited flexibility for companies managing multiple debt issuances.
What has changed
The total limit for maturing ISINs has been raised to seventeen, with specific sub-limits for plain vanilla debt and structured products. Additionally, a mechanism now allows for more ISINs if the total outstanding debt amount exceeds Rs. 15,000 Crore.
Who this affects
Companies that issue listed debt securities on a private placement basis.
An example
A company issues plain vanilla bonds and has Rs. 16,000 Crore maturing in the next financial year. Under the old rules, they might have hit their limit sooner. Now, because they exceed the Rs. 15,000 Crore threshold, they are permitted one additional ISIN beyond the standard twelve, allowing for better management of their debt obligations.
What you should do
Review your current and planned debt issuance schedule to ensure the number of maturing ISINs aligns with these new limits. If you have existing structured debt, check if your legacy ISINs are grandfathered under the new rules.
Deadline · October 07, 2026If you do nothing
Failure to comply with these limits may result in regulatory scrutiny from stock exchanges and depositories, who are tasked with monitoring issuer compliance. You may be blocked from issuing new securities until your maturing ISIN count falls back within the permitted range.
