The U.S. Treasury will in the future issue sovereign bonds with maturities longer than 30 years, specifically 50-year and 100-year U.S. government bonds.
I think the thing you guys have to be open to is the fact that we've never really tested the ability for the US to borrow durations beyond 30 years... I do think that they'll be able to get durational assets that are that far out on the yield curve... So we'll have 50 year US bonds. We'll have 100 year US bonds.View on YouTube
Explanation

As of November 30, 2025, the U.S. Department of the Treasury has not issued 50‑year or 100‑year nominal Treasury bonds. The longest standard maturity remains the 30‑year Treasury bond.

Evidence:

  • The Treasury’s current marketable securities lineup (bills, notes, bonds, and TIPS) continues to list bonds only out to 30 years as the longest maturity; there is no 50‑year or 100‑year instrument offered as a regular product.
  • Discussions about ultra‑long U.S. Treasuries (50‑ or 100‑year) have occurred repeatedly in policy and market commentary (e.g., around 2016, again in 2019–2020, and after large deficits in the 2020s), but each time the Treasury Borrowing Advisory Committee and Treasury officials have ultimately decided against introducing such maturities, citing concerns about demand depth, market functioning, and overall financing strategy.

Because the prediction was that “we’ll have 50 year US bonds. We’ll have 100 year US bonds” and enough time has passed to check whether such instruments exist (they do not), the forecast is incorrect as of now.
