SEBI lifts ISIN ceiling to 17, easing bond repayment pressure for NBFCs

What Happened

The Securities and Exchange Board of India (SEBI) raised the ceiling on the number of ISINs that can mature in a financial year from 14 to 17 in a circular issued on 7 October. The change also adds six extra ISINs for capital‑gains‑tax bonds issued under Section 54EC.

Impact on NBFCs

Under the new rules, up to 12 ISINs may be used for plain‑vanilla debt securities, an increase from the earlier nine. Issuers receive one additional ISIN for every further ₹3,000 crore of outstanding debt beyond ₹15,000 crore. Five ISINs are reserved for structured, market‑linked, floating‑rate, zero‑coupon and Tier II bonds; if only these are issued, the overall limit stays at 12. The previous cap forced many borrowers, especially non‑banking financial companies, to concentrate repayments in a few windows, creating liquidity strain when large amounts came due together. By spreading maturity dates, NBFCs can better match debt servicing with the monthly cash flows from their loan books, lowering refinancing risk. Investor preferences also shift with the new flexibility. Fresh issuances can be timed to current market rates, avoiding the need to refinance a 6.5 % coupon bond when prevailing rates have risen to around 8 %.

Context

ISINs are unique 12‑character codes that identify each bond for trading and settlement. Excluding government‑serviced, Extra Budgetary Resources and ESG bonds from the limit acknowledges their distinct policy roles and prevents them from crowding out corporate financing capacity.
