The market for Treasury Inflation-Protected Securities made a bit of history today, with the auction of $9 billion in a new 30-year TIPS getting a real yield of 2.403%, the highest for this term since October 2001.
Of course, we have to recognize that the Treasury stopped issuing 30-year TIPS from October 2001 to February 2010. Since that restart, no 29- to 30-year TIPS auction has received a real yield higher than 2.29%. Until today.
This is CUSIP 912810UH9, and the auction sets its coupon rate at 2.375%, also the highest for this term in 23 years. The auction appears to have come in right on target. The “when-issued” yield prediction — revealed just before the close at 1 p.m. EST — was very close at 2.400%. The bid-to-cover ratio was a solid 2.48.
This is a good result for investors, who will earn 2.403% over official U.S. inflation for the next 30 years. Just a reminder: As recently as March 9, 2022 — less than three years ago — the nominal yield on a 30-year Treasury bond was 2.29%, less than the real yield of today’s result. This is a nice turn for investors seeking safety.
Here is the trend in the 30-year real yield over the last five years, showing the remarkable surge higher after the end of the Federal Reserve’s pandemic-era quantitative easing in March 2022:
Pricing
This is a new TIPS, so investors could be assured that the coupon rate (2.375%) would be set slightly below the real yield of 2.403%. That resulted in a discounted unadjusted price of 99.403433. In addition, this TIPS will have an inflation index of 1.00016 on the settlement date of February 28.
With this information, we can calculate the exact cost of a purchase of $10,000 par value of this TIPS at today’s auction:
- Par value: $10,000.
- Adjusted principal purchased: $10,000 x 1.00016 = $10,001.60
- Cost of investment: $10,001.60 x 0.99403433 =$9,941.93
- + accrued interest of $8.53
In summary, an investor buying $10,000 par of this TIPS at today’s auction paid $9,941.93 for $10,001.60 of principal and will now earn inflation adjustments equal to inflation for 30 years, plus an annual coupon of 2.375% paid on inflation-adjusted principal.
Inflation breakeven rate
At the auction’s close, the 30-year Treasury bond was trading with a nominal yield of 4.74%, meaning this TIPS gets an inflation breakeven rate of 2.34%, a bit high compared to recent trends. This reflects a lack of investor confidence in the Federal Reserve’s ability to put tight controls on future inflation. Inflation over the last 30 years, ending in January, has averaged 2.5%.
Here is the trend in the 30-year inflation breakeven rate over the last five years, showing how inflation expectations have been locked in a narrow pattern (but highish) for the last three years:
Thoughts
This is a very good result for investors who can accept the 30-year time frame and hold to maturity. CUSIP 912810UH9 is the most attractive 30-year TIPS issued in 24 years, in my opinion. But I wasn’t a buyer because the long maturity doesn’t fit into my likely lifespan.
We are heading into uncertain economic times. Both real and nominal yields could be heading higher. Still, getting 2.403% over inflation for 30 years, guaranteed, is attractive and sensible, in my opinion.

I was happy to get the nearly 2% above inflation on this issue. I'm also still nibbling at long-term bonds…
