What Is Commercial Paper And Why Did Stablecoins Hold It?
Stablecoin reserves sound like they should be simple: dollars, held safely, ready to redeem on demand. For a period of time, though, a meaningful share of some reserves consisted of a short-term corporate IOU that most holders had never heard of before it became a subject of scrutiny.
The short answer
Commercial paper is short-term, unsecured debt issued by corporations to cover near-term operating needs, typically maturing anywhere from a few days to several months. Some stablecoin issuers historically held it as part of their reserves because it paid more than holding plain cash while still being considered relatively short-dated — though how easily it can actually be sold before maturity, especially during a period of market stress, is a separate question from how short-dated it is on paper.
What commercial paper actually is
Commercial paper is essentially a promise: a corporation borrows money for a short period, usually to cover things like payroll or inventory purchases, and sells that debt to investors at a discount to its face value, paying back the full amount at maturity. It’s unsecured, meaning it isn’t backed by specific collateral, and it relies on the borrowing company’s general creditworthiness. Maturities are typically measured in days or weeks rather than years, which is what puts it in the same general category as other short-term, cash-like instruments.
Why holding it appealed to some issuers
Holding reserves purely in cash generates little to no return, so some stablecoin issuers historically allocated part of their reserves to instruments like commercial paper as a way to earn some yield on the money backing their coins, while still keeping those holdings relatively short-term compared to longer-duration investments. The appeal was straightforward: slightly better return than cash, while nominally staying within a category viewed as safe and liquid under normal conditions.
The liquidity risk this introduces
The catch is that “relatively liquid” and “instantly convertible to cash” aren’t the same thing, a distinction closely tied to the broader idea of market liquidity — how easily an asset can actually be sold without moving its price or requiring a discount. Commercial paper still has to be sold to someone, or held to maturity, to become cash. Under normal market conditions that’s usually straightforward. Under stressed conditions — exactly when a stablecoin issuer might face a surge of redemption requests — selling commercial paper quickly can require accepting a discount, or in extreme cases, finding a buyer at all can become difficult. That mismatch, between reserves that aren’t instantly liquid and redemption demand that can spike suddenly, is a core piece of the mechanics behind a bank-run-style depeg, where the speed of withdrawals outpaces the speed at which backing assets can be converted to cash.
Why this became a bigger part of the conversation
Reserve composition and disclosure moved to the center of stablecoin discussions as regulators and the public began asking more pointed questions about exactly what backs a coin’s peg, and how quickly those backing assets could actually be accessed if needed. This is a separate issue from the mechanism behind an algorithmic stablecoin, which maintains its peg through a coded mechanism rather than through reserve assets at all — but both raise the same underlying question of what actually stands behind a promise of stability, and how that promise holds up under pressure.
What to weigh
None of this means commercial paper is inherently unsafe as an investment category in general, but it illustrates a broader point: reserve quality and reserve liquidity are two different things, and a reserve can be fully backed on paper while still being difficult to convert to cash quickly enough to meet a sudden wave of redemptions. Stablecoin holdings, like other crypto holdings, generally fall outside FDIC protection and the kind of SIPC coverage that can apply to certain brokerage assets, and the rules governing what reserves must consist of, and how they must be disclosed, continue to evolve and vary by jurisdiction.
The bottom line
Commercial paper is an ordinary, common financial instrument in corporate finance — the notable part isn’t the instrument itself, but what its presence in stablecoin reserves revealed about the gap between “backed” and “instantly redeemable,” a distinction that matters most exactly when it’s tested.
