Unsecured bonds are loans a company issues that are not backed by specific assets or collateral; investors rely on the issuer’s promise to pay rather than a claim on property if the company fails. They matter to investors because they carry higher risk than secured debt—so issuers usually pay higher interest—but also sit behind secured creditors in repayment order, which affects potential recovery if the issuer defaults.
