A ten-year Treasury pays 5.11%. That is the number everything else has to beat.
The 10-year closed Wednesday at a level it last saw in 2007. When the safe option pays this much, the bar for every other plan moves with it.

The Treasury's daily par yield curve for Wednesday put the 10-year note at 5.11% and the 30-year bond at 5.45%. Three-month bills came in at 4.10%. The last day the 10-year closed at or above 5.11% was July 13, 2007.
Read past the market story, because there is a personal one under it. Every dollar you hold has a safe alternative, and for most of the last twenty years that alternative paid close to nothing. In August 2020 the 10-year got down to 0.52%. At 0.52% you never had to ask whether a plan was worth doing, because almost anything beat it. At 5.11% you do.
The honest version of that number is 2.63%
A 5.11% yield includes whatever the market expects inflation to do for ten years, so it flatters itself. The clean read is the 10-year Treasury Inflation-Protected Security, which is quoted net of inflation. On Tuesday that real yield was 2.63%, and it had not been that high on a single trading day since November 26, 2008. That gap covers the entire 2010s.
Sit with what it means rather than what it is called. A 10-year TIPS bought this week is a contract to beat inflation by roughly 2.6% a year for a decade, whatever inflation turns out to be, backed by the Treasury. Use 5.11% when you are doing arithmetic. Use 2.63% when you want to know whether a plan is actually any good.
A hurdle rate is just the thing you compare against
Write your best safe alternative on a sticky note. That is your hurdle, and every plan you are weighing either clears it or does not. Ten thousand dollars compounding at 5.11% for ten years is $16,460. The same ten thousand at 4.10%, roughly what short bills pay right now, is $14,945. On $25,000 the ten-year gap is about $3,788, and the only thing separating the two numbers is how long you were willing to commit the money.
It does more work on debt. Freddie Mac put the 30-year fixed at 6.95% in the week of September 17, so paying a new mortgage down early is a guaranteed 6.95% and beats buying the note. A 3% mortgage signed in 2021 is the reverse: that dollar earns 3% against the balance and 5.11% in a Treasury. A credit card is not a close call at all. The Fed's G.19 data put the average card APR at 20.94% in the second quarter. Money doubles in about 3.6 years at 20.94% and takes 13.9 years at 5.11%.
One caution before you treat a one-point gap as found money. Treasury interest is taxable federally, though exempt from state and local income tax, and mortgage interest only helps if you itemize. The comparison that counts is after tax, in your bracket.
You get paid to lock money up again
Look at the two ends of Wednesday's curve: 4.10% for three months, 5.11% for ten years. A full point for committing. That sounds ordinary and it is genuinely new.
Through most of the three years from October 2022 to October 2025, the 10-year paid less than a three-month bill. 621 trading days out of 749, with the gap reaching 1.89 points the wrong way in May 2023. Locking money up was punished, staying short was correct, and plenty of us built the habit. Not one trading day since October 16, 2025 has been inverted.
That habit now costs something on money with a real date attached. If the Fed eases, bill and money market yields follow within weeks; a note bought this week pays 5.11% until 2036 either way. The tradeoff is honest: you earn that yield by holding to maturity, and selling early into higher rates means taking a loss on the price. So match the term to the date. Tuition eight years out can be locked. Next spring's roof cannot.
What this is not
It is not a signal to sell stocks. Bonds paying nothing was never the argument for owning equities, and a 5% coupon says nothing about what shares do over a decade. A hurdle rate is for deciding where the next dollar goes, not for rearranging what you already own because of a headline.
It is not your savings rate either. The 10-year is a bond yield. Your bank picks its own number, and most banks pick a low one, so go read the APY on your statement before assuming the good news reached you. Nor is 5.11% purchasing power: August CPI had prices up 3.4% over the year, which is why the 2.63% the TIPS market quotes is the figure to hold onto.
And the best return available to most people is still nowhere near the bond market. A dollar-for-dollar employer match doubles a dollar the moment it lands, before it earns a cent. Clearing a 20.94% balance returns 20.94%, guaranteed, starting this month. Do those first, then come back to 5.11%.
Don't
- 🚫Read a 5% headline as a reason to sell long-term holdings
- 🚫Assume your savings account or money market pays anything close to 5.11%
- 🚫Buy a 10-year note with money you might need in three years
Do
- ✅Write down your hurdle rate and hold every plan up against it
- ✅Clear anything costing more than 5.11% before buying something that pays it
- ✅Lock a rate on money with a date years out, and keep the rest liquid
The takeaway
A safe 5.11% for ten years, or 2.63% above inflation, is the best deal savers have been offered in nearly twenty years. It is also the new bar. Anything you want to call an investment has to clear it, and the two things that clear it comfortably are an employer match and a 20.94% card balance.
