18 USC 8
The U.S. government’s ability to meet obligations is governed by the Constitution (e.g., Article I powers to tax and borrow), statutes authorizing borrowing and appropriations, and the Treasury’s operations.
The federal government is not subject to the Bankruptcy Code in the same way private parties are; sovereign immunity and the distinct status of the United States mean you cannot force the federal corporation into a Chapter 11 bankruptcy proceeding. That practical reality, plus Congress’s power to borrow and tax, is why arguments that the U.S. is “bankrupt” in a way that voids federal obligations are legally unsupported.
18 U.S.C. § 8 helps identify what instruments are government obligations (so misuse or counterfeiting of those instruments can be prosecuted), but it does not declare that the U.S. always has unlimited ability to pay or nullify bankruptcy law.
Short legal takeaway: § 8 is a definitional rule used for criminal and related statutes; it supports treating certain instruments as official U.S. obligations. It does not, however, by itself create the legal basis to claim the U.S. cannot be obligated to pay or that claimed “bankruptcy” by the U.S. nullifies those obligations. So the United States is not bankrupt or in bankruptcy the codes, the statute of bankruptcy were created by the United States therefore the United States is ?
