This market resolves YES if the US federal government has, on or after January 1, 2026 and on or before December 31, 2030, unilaterally restructured previously-issued outstanding marketable US Treasury notes, bonds, or TIPS without bondholder consent.

Statutory cap on Treasury interest payments that materially reduces coupon receipts on outstanding debt
Targeted excise/withholding tax on Treasury coupon income applied retroactively to outstanding debt
NO if none of the above has occurred by December 31, 2030, or if only the following have occurred:
Voluntary exchange offers where holders consent
Maturity-neutral debt buybacks at market prices
Treasury bill restructurings or non-marketable securities restructurings
Technical defaults cured within ordinary administrative timelines
General tax-rate changes affecting after-tax yield
Federal Reserve balance-sheet operations on Treasuries it holds

1,000Yes, the US government has effectively restructured Treasury debt, most notably in 1933.
The 1933 Gold Clause Abrogation
This is the clearest and most significant historical example. During the Great Depression, the US unilaterally altered the terms of existing Treasury securities (and private contracts) by abrogating gold clauses. These clauses, common in bonds issued before 1933, required repayment in gold coin or its equivalent, protecting holders from currency devaluation.
On June 5, 1933, Congress passed a joint resolution voiding gold clauses retroactively.
In January 1934, the dollar was officially devalued by about 41% (gold price raised from $20.67 to $35 per ounce).
Bondholders were paid in the new, depreciated dollars instead of gold-equivalent value.
Economists and researchers, including a 2015 NBER working paper, explicitly describe this as a unilateral debt restructuring that imposed significant losses on investors (roughly a 41% reduction in real value for affected debt). The Supreme Court upheld it in 1935 (in cases like Perry v. United States), ruling that Congress could regulate the value of money, though some justices dissented strongly, calling it a repudiation.
Impacts:
It transferred wealth from creditors to debtors on a massive scale (debts involved were ~1.7x GDP).
Despite a temporary "flight to quality" in markets, the Treasury faced little difficulty issuing new debt or rolling over existing obligations. Borrowing costs rose only marginally.
This is sometimes classified as a sovereign default or restructuring in historical databases (e.g., by Reinhart and Rogoff).
Other Historical Episodes
1814 (War of 1812): The Treasury faced severe cash shortages and failed to make some interest payments on time (e.g., to Boston creditors), leading to dishonored notes. This was a temporary technical default due to wartime disruptions, not a formal restructuring with altered terms. Payments were eventually made after the war, and it did not involve broad changes to debt contracts.
No other major modern-style restructurings (e.g., principal haircuts, maturity extensions negotiated with creditors, or Brady-style bond exchanges) have occurred. The US has an exceptionally strong record of meeting obligations in nominal terms.
Context and Distinctions
US Treasuries are considered among the safest assets globally precisely because outright defaults or coercive restructurings are extremely rare. The 1933 event was tied to abandoning the gold standard amid crisis, not fiscal insolvency. Debt ceiling debates or delays (e.g., 1979 "mini-default" on small payments due to processing issues) have caused short disruptions but not restructurings.
In summary, while the US has never done a conventional emerging-market-style debt restructuring, the 1933 gold clause abrogation qualifies as one under standard economic definitions.
