Commercial paper is short-term corporate funding issued as promissory notes; learn discount pricing, maturity, ABCP, rollover risk, backup liquidity, and key comparisons.
Commercial paper (CP) is a short-term promissory note issued primarily by corporations to fund working capital and other near-term cash needs. Traditional CP is generally unsecured, matures quickly, and is sold to money-market investors either directly by the issuer or through a dealer.
The Federal Reserve describes U.S. CP as having maturities of up to 270 days, with an average maturity of about 30 days. That U.S. convention should not be treated as a universal legal definition: issuance rules, disclosure, eligible investors, and market practices vary by jurisdiction and program.
An issuer establishes a CP program with maximum outstandings and operating procedures. It then sells individual notes in the maturities and amounts investors will accept. At maturity, the issuer pays the note’s face amount using operating cash, committed bank liquidity, proceeds from long-term financing, or proceeds from newly issued CP.
That final method is called rolling the paper. It works only while investors remain willing to buy the issuer’s new notes. A solvent company can therefore face a liquidity problem if the CP market closes or demands an uneconomic rate.
Many established programs maintain committed bank facilities or other backup liquidity. The analyst should verify the amount, expiry, conditions to draw, competing uses, and whether the facility remains available after a rating downgrade or other stress. A nominal backup line is not useful if it expires before the CP, cannot be drawn when needed, or is already supporting other obligations.
| Feature | Traditional corporate CP | Asset-backed commercial paper (ABCP) |
|---|---|---|
| Issuer | Operating or finance company | Special-purpose conduit or vehicle |
| Credit support | Primarily issuer credit; may also have a guarantee or bank support | Asset cash flows plus program-level liquidity or credit support |
| Common funding purpose | Working capital and short-term corporate liquidity | Financing pools such as receivables or other eligible assets |
| Core analysis | Issuer liquidity, rating, maturities, backup lines | Asset quality, structure, sponsor, liquidity provider, triggers, maturity mismatch |
| Main stress risk | Loss of direct market access | Asset deterioration, support-provider weakness, or inability to refinance maturing paper |
Calling ABCP “asset-backed” does not eliminate risk. Investors must understand the issuing vehicle, asset eligibility, credit enhancement, liquidity support, triggers, and priority of payments. The assets often mature later than the paper, creating a funding mismatch that depends on continued issuance or committed support.
Assume a company issues 90-day CP with a $10 million face amount at a quoted 5.20% bank discount rate using a 360-day convention.
The discount is:
$10,000,000 x 5.20% x (90 / 360) = $130,000
The investor pays:
$10,000,000 - $130,000 = $9,870,000
If the issuer pays face value at maturity, the investor receives a $130,000 dollar return before transaction costs and taxes. The quoted 5.20% discount rate divides the discount by face value. A simple annualized return based on the amount invested is slightly higher:
($130,000 / $9,870,000) x (360 / 90) = approximately 5.27%
Yield conventions are not interchangeable. Analysts should confirm whether a quote is a bank discount yield, money-market yield, bond-equivalent yield, effective annual yield, or actual price.
| Instrument | Borrower or issuer | Typical credit basis | Deposit insurance or government backing | Main distinction |
|---|---|---|---|---|
| Commercial paper | Corporation or issuing vehicle | Corporate or program credit | None merely because it is CP | Short-term market note with rollover risk |
| Treasury bill | National government | Sovereign obligation | Direct government obligation under its terms | Government rather than corporate credit |
| Certificate of deposit | Bank or credit institution | Bank obligation | Coverage depends on institution, product, jurisdiction, and limits | Deposit instrument rather than corporate note |
| Revolving bank facility | Corporate borrower | Borrower plus guarantees and collateral, if any | Not applicable | Contractual availability subject to facility terms |
| Corporate bond | Corporate issuer | Issuer and instrument structure | None merely because it is a bond | Generally longer maturity and less frequent rollover |
For an issuer with market access, CP can provide flexible amounts and maturities and may cost less than drawing a bank facility. It can bridge timing gaps between cash receipts and payments or provide interim funding before a longer-term financing closes.
Those advantages are conditional. Dealer fees, backup facilities, ratings, operational requirements, and market volatility contribute to all-in cost. CP is not automatically available to every company, and a low initial rate does not compensate for an unmanageable refinancing concentration.
