The yield curve has gone negative - the shorter term bonds are worth more than the longer term ones (and certainly the longer term ones bought back in 2021).
And if you were trying to sell me a 10 year note at 0.6% I'd want a serious discount because even your 7 year note at 3.86%, I can do better with a 3 month note at 4.794% or a 6 month note at 5.086%. https://www.marketwatch.com/investing/bond/tmubmusd03m?count...
But that's if you were trying to sell it now. The amount it will pay at maturity remains unchanged and in 10 years it will be worth exactly the same no matter what the financial history that brought it to that point was.
