On a day when real and nominal yields were creeping higher, the Treasury’s auction of $26 billion in a new 5-year Treasury Inflation-Protected Security got a real yield to maturity of 1.367%, a good result for investors.
This is CUSIP 91282CQP9. The auction result set its coupon rate at 1.250%. The real yield of 1.367% was very slightly higher than the when-issued prediction of 1.365%. The bid-to-cover ratio was decent at 2.57. This auction was well supported by investors.
All morning, I had been tracking the nominal 5-year Treasury yield, which had been inching higher from 3.88% around 8 a.m. to 3.95% at the auction’s close. That rise, possibly connected to continued dim news from the Mideast, could have been a factor in today’s auction result by pulling real yields higher.
Definition: The “real yield to maturity” of a TIPS is its yield above future U.S. inflation, over the term of the TIPS. So a real yield of 1.367% means an investment in this TIPS would provide a return that exceeds official U.S. inflation by 1.367% for 5 years.
Here is the trend in the 5-year real yield over the last year, based on Treasury estimates, showing that today’s result is in the mid- to -lower range, but higher than very recent trends.
Pricing
This is a new TIPS, so its coupon rate was set to the 1/8th percentage point below the auctioned real yield. That resulted in an unadjusted price of 99.440535, a slight discount. In addition, this TIPS will carry an inflation index of 1.00235 on the settlement date of April 30. With that information, we can calculate the cost of a $10,000 par value purchase at this auction:
- Par value: $10,000.
- Principal on settlement date: $10,000 x 1.00235 = $10,023.50.
- Cost of investment: $10,023.50 x 0.99440535 = $9,967.42.
- + accrued interest of $5.13 .
In summary, an investor purchasing $10,000 par value of this TIPS paid $9,967.42 for $10,023.50 in principal on the settlement date. From then on, the investor will earn accruals matching future inflation, plus an annual coupon rate of 1.25% on adjusted principal. The accrued interest will be returned at the first coupon payment on October 15.
Inflation breakeven rate
At the auction’s close, the 5-year Treasury note was trading with a nominal yield of 3.95%, which creates an inflation breakeven rate of 2.58% for this TIPS, the highest level at auction for this term since October 2022. Clearly, developments in the Mideast are raising inflation fears, especially in the shorter term.
Here is the trend in the 5-year inflation breakeven rate over the last year:
Thoughts
Even though the real yield was well below the 1.702% generated at last April’s originating auction, this seems like a decent result. Since April 2025, the Federal Reserve has cut short-term interest rates by 75 basis points. But at this point, the Fed looks likely to keep rates stable for several months.
In my preview article for this auction, I noted: “I think a real yield level around 1.30% to 1.35% seems reasonable. The Fed won’t be cutting rates anytime soon.” Market yields change by the minute, especially in the midst of global disruptions.
At mid-morning, I asked three AI bots to predict the result of today’s auction. Here were their predictions:
Claude and ChatGPT used my article to predict a range of 1.30% to 1.35%, which due to today’s market events ended up being a bit too low. Google’s Gemini ignored my input and overshot the yield by a wide margin.
TIPS auction results have always been difficult to predict. I’ve learned to be careful, qualified and modest in my predictions.
