What Is Commercial Paper?

Updated July 9, 2026 5 min read

Large companies sometimes need cash for a matter of weeks, not years, and issuing a full-scale bond for that would be overkill. There’s a shorter, simpler tool built specifically for that gap.

The short answer

Commercial paper is short-term, unsecured debt that companies issue to cover near-term cash needs, such as payroll, inventory purchases, or other working capital gaps. It’s typically sold at a discount to its face value rather than paying a stated interest rate, and it usually matures within a short window measured in days to a few months, rather than years.

How maturities and pricing typically work

Commercial paper is generally issued with maturities on the shorter end of the spectrum, often just a matter of weeks, though it can extend out further. Rather than paying periodic interest, it’s sold below its face value, and the investor’s return comes from the difference between the discounted purchase price and the full amount received at maturity, similar in spirit to how a zero-coupon municipal bond is priced, though commercial paper is a taxable, short-term instrument rather than a municipal one. It’s also considerably shorter in maturity than a medium-term note, which covers a different stretch of a company’s borrowing needs.

Why it’s unsecured and what that means

Like a debenture, commercial paper isn’t backed by specific collateral; it relies on the issuing company’s general creditworthiness. Because of that, commercial paper is generally issued by larger, well-established companies whose credit standing is strong enough to attract buyers without pledging assets. Its short maturity also reduces the window of risk somewhat, since investors aren’t extending credit for years at a time, but the lack of collateral still means repayment depends entirely on the issuer remaining able to pay.

Why companies rely on it

Where individual investors encounter it

Most individual investors don’t buy commercial paper directly, since it’s typically issued in large denominations aimed at institutional buyers. Instead, individual exposure usually comes indirectly, through a money market account or fund, which often holds commercial paper alongside other very short-term instruments as part of its underlying portfolio. That’s part of why the credit quality of a money market fund’s holdings, including any commercial paper, is worth understanding even for someone who never buys the instrument directly.

What to weigh

Commercial paper plays a narrow but useful role in short-term corporate financing, and by extension, in some of the money market funds that individual savers use for cash they want to keep liquid. Because it’s unsecured and depends on the issuer’s short-term financial health, the same principle applies here as with any credit instrument: the appeal of a discount or a slightly higher yield only makes sense once the underlying issuer’s ability to repay is understood.
