Definition ∞ Treasury bill backing refers to the practice of using short-term debt obligations issued by national governments, known as Treasury bills, as collateral or reserves for another financial instrument. This backing provides a high degree of safety and liquidity due to the government’s creditworthiness. It is a common method for stabilizing asset value.
Context ∞ For stablecoins, treasury bill backing is a prominent method for maintaining their peg to fiat currencies, offering a highly liquid and secure reserve asset. The composition and auditing of these reserves are under intense scrutiny by regulators, who demand transparency to ensure the stablecoin’s stability and protect consumers. This approach seeks to mitigate risks associated with less secure or volatile collateral.
