So I, again, am less concerned about the debt wall here, because I think you'll be able to push maturities out. You'll be able to refi a bunch of short term obligations into the future... I would be very surprised if 100 year rates, if they priced a bond weren't somewhere sub 1%. So I do think it becomes effectively free money for the United States.View on YouTube
As of now (through November 30, 2025), the U.S. Treasury has not issued any 100-year Treasury bonds.
Public reporting and Treasury documentation show that while ultralong maturities (including 50- and 100-year bonds) have been repeatedly studied or discussed, they’ve never been brought to market in the modern era. The Treasury Borrowing Advisory Committee and Treasury officials have confirmed on multiple occasions that ultralong bonds were evaluated but not issued, with supply focused instead on the existing curve out to 30 years.
Because the prediction is explicitly about the yield level “if and when” 100‑year bonds are issued, and that condition has not occurred yet, there is no market yield to observe and thus no way to test whether the yield would, in fact, come in below 1%.
So the prediction is neither confirmed nor falsified at this time; it depends on a future policy decision and subsequent market pricing that have not happened yet.
