What Is Commercial Paper?
Commercial paper is an unsecured, short-term debt instrument issued by corporations to meet their immediate funding needs. It is commonly used to cover short-term liabilities such as payroll, accounts payable, and inventory purchases. Typically, commercial paper is issued in denominations of $100,000 or more, with maturities ranging from 1 to 270 days, averaging around 30 days. This instrument is sold at a discount and redeemed at its full face value upon maturity.

- Corporations use it to finance short-term expenses like payroll and inventory.
- Maturity periods vary between 1 and 270 days, commonly around 30 days.

Historical Background of Commercial Paper
Originating during colonial times as bills of exchange, commercial paper evolved in the 1920s when New York merchants started selling short-term obligations to dealers to raise capital for immediate needs. These dealers purchased promissory notes at discounts and resold them to banks and investors. The merchants repaid the investors the full par value upon maturity.
Unlike asset-backed commercial paper (ABCP), commercial paper is unsecured and not backed by collateral, typically resulting in higher yields. Only corporations with strong credit ratings issue commercial paper, allowing them to attract buyers without offering steep discounts.
Large institutions, financial firms, and affluent individuals commonly purchase commercial paper, which is issued in large denominations starting at $100,000.
Interesting Fact
Marcus Goldman, founder of Goldman Sachs, was a pioneering dealer in commercial paper, becoming one of the largest dealers in America post-Civil War.
Various Types of Commercial Paper
Corporations issue different forms of commercial paper based on their financing needs. Key types include:
Promissory Notes
Written commitments to pay a specified sum by a certain date, promissory notes allow companies to borrow without collateral. They are sold at a discount and redeemed at face value, with maturities ranging from a few days to a year.
Drafts
Drafts are written orders from one party to another (usually a bank) to pay a third party a specified amount. Used in trade finance, drafts can be payable on demand (sight drafts) or at a future date (time drafts).
Bankers’ Acceptances
These are time drafts guaranteed by a bank, commonly used in international trade to assure exporters of payment. Bankers' acceptances can be traded on secondary markets before maturity.
Certificates of Deposit (CDs)
Issued by banks, CDs pay fixed interest over a set period and are considered low-risk due to bank backing. Large-denomination CDs are often grouped with commercial paper because of their liquidity and short-term nature.
Repurchase Agreements (Repos)
Repos involve selling securities with an agreement to repurchase them later at a predetermined price. These secured transactions function as short-term loans in money markets.
Key Terms of Commercial Paper
- Issuer: Usually large corporations with strong credit profiles issuing short-term debt to cover immediate cash needs.
- Term/Maturity: Duration the debt is outstanding, typically up to 270 days, often around 30 days.
- Secured/Unsecured: Generally unsecured, meaning no collateral backs the debt, relying on issuer creditworthiness.
- Discount/Face Value: Issued at a discount and redeemed at face value, with the difference representing interest.
- Liquidity: Enhances issuer liquidity for short-term needs; investors hold it as a liquid asset.
Note
While similar to bonds, commercial paper has distinct characteristics, such as shorter maturities and no periodic interest payments.

Commercial Paper vs. Bonds
Although both are debt instruments, commercial paper is short-term (1 to 270 days) and unsecured, with no coupon payments, while bonds are longer-term (1 to 30 years), often secured, and pay periodic interest.
Example of Commercial Paper in Action
