SEBI raised the annual cap on privately placed debt ISINs per issuer from 14 to 17, giving companies more flexibility to stagger bond maturities and manage cash flows. Separately, SEBI removed the mandatory merchant banker requirement for eligible issuers accessing the private placement debt market. Both changes aim to deepen India's corporate bond market by reducing issuance friction and allowing issuers to spread repayment obligations across a wider range of maturity buckets.

An ISIN (International Securities Identification Number) uniquely identifies each debt security. When SEBI caps the number of ISINs an issuer can create in a year, it effectively limits how many distinct maturity tranches that issuer can float. The old cap of 14 annually constrained large borrowers who needed to raise funds at different maturities to match their asset-liability profiles — forcing bunching of repayments and higher refinancing risk.

By raising the cap to 17, SEBI allows issuers three additional maturity windows per year. This is especially significant for infrastructure companies, NBFCs, and PSUs that routinely access the private placement route and need granular maturity management.

The removal of the merchant banker mandate for eligible issuers is an equally important deregulatory step. Merchant bankers act as intermediaries who conduct due diligence and manage the issuance process. Making their involvement optional for certain issuers reduces compliance costs and speeds up market access — though SEBI likely retains the requirement for issuers below eligibility thresholds to protect investors.

Together, these changes align with SEBI's broader push to develop India's corporate bond market as an alternative to bank credit, a recurring regulatory theme since the 2016 report of the H.R. Khan Committee on corporate bonds. For the exam, understand that privately placed debt (as opposed to publicly issued bonds) is governed by SEBI's regulations on non-convertible securities, and that ISINs are the operational unit through which market infrastructure (depositories, clearing corporations) tracks each instrument.
