Why commercial paper matters
The market is an important source of low-cost wholesale funding for strong issuers. For investors, it can provide short-duration income, but repayment depends primarily on issuer credit and access to liquidity because the paper is generally unsecured.
How it is applied
Credit analysts review issuer quality, maturity, liquidity facilities, cash needs, refinancing capacity, program size, currency, and dealer access. Money-market investors also monitor concentration, eligible maturity, valuation, and regulatory requirements. Credit analysis focuses on issuer liquidity, short-term ratings, bank backstops, maturity concentration, and access to replacement funding. Treasury teams stagger maturities and compare yields with deposits and government bills. Asset-backed programs additionally require review of collateral, conduits, liquidity facilities, and sponsor support.
Portfolio example
A company issues 90-day paper for $9.90 million and repays $10 million at maturity. The $100,000 difference is the investor’s gross discount income before transaction, tax, and day-count effects. A company sells 10 million face value of 90-day paper for 9.88 million and repays 10 million at maturity. The 120,000 discount is the investor’s gross income before day-count conversion, fees, and tax. The issuer must have cash or refinancing available on the exact maturity date.
How to interpret it
A slightly higher yield than government bills may compensate for credit and liquidity risk. Very short maturity reduces rate sensitivity but does not eliminate the possibility of default or a funding-market freeze. A small yield premium over government bills can compensate for credit and liquidity risk, but it should be judged against the issuer’s financial strength and backup facilities. Widening commercial-paper spreads may indicate market-wide funding stress rather than deterioration in one borrower.
Limitations and common misconceptions
Commercial paper often relies on repeated refinancing, creating rollover risk. Secondary trading can be limited, ratings can lag deterioration, and bank backup lines may have conditions. Asset-backed commercial paper adds collateral and structural risks. Paper is generally unsecured and exposes investors to rollover and event risk despite its short maturity. Markets can close abruptly, forcing issuers onto bank lines or asset sales. Ratings can change after adverse news, and secondary-market liquidity may be limited before maturity.
