Risk free interest rate

Lendings to stable financial entities such as large companies or governments are often termed “risk free” or “low risk” and made at a so-called “risk-free interest rate”. This is because the debt and interest are highly unlikely to be defaulted. A good example of such risk-free interest is a US Treasury security - it yields the minimum return available in economics, but investors have the comfort of the (almost) certain expectation that the US Treasury will not default on its debt instruments. A risk-free rate is also commonly used in setting floating interest rates, which are usually calculated as the risk-free interest rate plus a bonus to the creditor based on the creditworthiness of the debtor (in other words, the risk of him defaulting and the creditor losing the debt). In reality, no lending is truly risk free, but borrowers at the “risk free” rate are considered the least likely to default.
