Credit Rating and Commercial Paper

Commercial paper is a short-term, unsecured money market instrument used by companies to meet working capital and other short-term funding needs directly from investors, and a minimum credit rating from a recognised agency is a firm regulatory precondition for issuance under the applicable RBI framework.

What Commercial Paper Is and Why Companies Use It

Commercial paper, commonly abbreviated CP, is a short-term, typically unsecured promissory note issued by eligible companies to raise funds directly from investors for periods generally ranging from a few days up to one year, used most commonly to meet working capital requirements as an alternative or supplement to bank-financed working capital facilities discussed in the previous pillar of this content series. Companies with strong, well-established credit profiles often use commercial paper because it can offer more competitive short-term funding costs than equivalent bank facilities, while also diversifying their funding sources away from exclusive reliance on their banking relationships.

The Minimum Rating Requirement

RBI's regulatory framework governing commercial paper issuance requires issuers to obtain a rating from a SEBI-registered credit rating agency, and historically has specified a minimum short-term rating threshold — commonly referenced in the market as an A3 rating or its equivalent, though companies should verify the current minimum threshold directly with RBI's applicable guidelines or a qualified advisor, since these requirements are periodically reviewed and can be revised. Companies whose short-term rating falls below the applicable minimum threshold are generally not eligible to issue commercial paper at all, making this one of the more clearly binary, rating-dependent capital market access points a company can encounter.

How the Rating Level Affects Pricing and Investor Demand

Within the pool of companies that clear the minimum eligibility threshold, the specific short-term rating achieved continues to matter significantly for pricing and investor demand — commercial paper from issuers with the highest short-term rating categories generally commands the most competitive pricing and the broadest investor interest, including strong demand from mutual fund debt schemes and other institutional investors for whom commercial paper is a common, liquid short-term investment instrument, while commercial paper closer to the minimum eligible threshold typically prices at a meaningfully wider spread and attracts a narrower investor base willing to accept the correspondingly higher perceived risk.

The Rollover Risk Dimension Specific to Commercial Paper

Because commercial paper is a short-term instrument, issuers typically need to roll over — that is, issue fresh commercial paper to repay maturing paper — repeatedly over time if they intend to use it as an ongoing funding source rather than a one-time transaction, a dynamic discussed in more depth in the dedicated rollover-risk article elsewhere in this pillar. This creates a particular sensitivity to the issuer's rating remaining stable or improving over time, since a rating downgrade partway through a programme of repeated commercial paper issuance can materially affect the issuer's ability to roll over maturing paper on comparable terms, or in a sufficiently severe downgrade scenario, its ability to roll over the paper at all — a risk companies relying heavily on commercial paper should plan for explicitly rather than assuming continuous market access.

How Commercial Paper Rating Differs From Long-Term Instrument Rating

Commercial paper is assessed and rated on a distinct short-term rating scale, different from the long-term rating scale used for instruments such as term loans, bonds, and NCDs discussed elsewhere in this pillar and this content series, reflecting the different analytical emphasis appropriate to a short-tenure instrument — near-term liquidity and cash flow adequacy typically carry proportionately more weight in a short-term rating assessment than the longer-horizon business and financial risk factors more central to a long-term rating. A company can, and often does, carry both a long-term rating for its other debt instruments and a distinct short-term rating specifically for its commercial paper programme, and the two, while related, are not simply interchangeable.

Illustrative Example

Consider a hypothetical large, well-established consumer durables company with a strong long-term rating that decides to establish a commercial paper programme to fund a portion of its seasonal working capital requirement more cost-effectively than through its existing bank facilities. The company achieves the highest short-term rating category, supporting competitive pricing and strong demand from mutual fund debt schemes that regularly invest in high-quality commercial paper as part of their liquid fund portfolios. Two years later, when the company experiences a period of weaker performance and a corresponding downgrade in both its long-term and short-term ratings, it finds that rolling over its outstanding commercial paper becomes noticeably more difficult, with several previously regular investors declining to participate at the next rollover and the company needing to offer a meaningfully higher rate to attract sufficient replacement demand — illustrating the rollover-risk dynamic specific to this instrument in a way a longer-tenure bond investor would not experience in the same acute, near-term form.

Frequently Asked Questions

What is the minimum rating needed to issue commercial paper?

RBI's framework specifies a minimum short-term rating threshold that issuers must meet, commonly referenced as an A3 rating or its equivalent in the market, though the current exact requirement should be confirmed directly with RBI's applicable guidelines since it is periodically reviewed.

Can a company with only a long-term rating issue commercial paper without a separate short-term rating?

No, commercial paper specifically requires its own short-term rating from a SEBI-registered agency; a long-term rating alone does not satisfy this requirement even for a company with a strong long-term credit profile.

How often is a commercial paper programme's rating reviewed?

Commercial paper ratings are subject to ongoing surveillance similar to other rated instruments, and given the short tenure and repeated rollover nature of the instrument, issuers and investors alike generally expect the rating to be kept current and reviewed at least as frequently as the applicable surveillance framework requires.

Is commercial paper riskier for investors than bank fixed deposits or NCDs?

Commercial paper is generally unsecured, which is a meaningful difference from many secured instruments, though its short tenure and the minimum rating requirement are both features designed to manage the risk; investors should evaluate any specific instrument on its own rating and terms rather than assuming a fixed risk comparison across instrument types.
