The Treasury’s auction of a new 5-year TIPS, CUSIP 91282CNB3, was a hard one to predict. Real yields have been sliding all over the place in the last week.
You might have seen real yield predictions as low as 1.53%, where the most recent 5-year TIPS was trading this morning. Or as high as 1.62%, the Treasury’s estimate at market close Wednesday. I expected a yield a bit higher than that.
The end result was a real yield of 1.702%, which I would consider a nice result for investors. The “when-issued” yield prediction, revealed just before the auction’s close, was 1.68%. The bid-to-cover ratio was a low-to-middling 2.28. All of this indicates weak investor demand for this auction.
In my preview article, I noted that the Treasury’s 5-year real yield estimate closed at 1.82% on Friday. But I expected volatility this week. And so it goes.
Here is the trend in the 5-year real yield over the last two years. The chart closes with the yield estimate on Tuesday. Note the higher auction result:

Pricing
The auction set the coupon rate for CUSIP 91282CNB3 at 1.625%, same as the October auction of a new 5-year TIPS, issued just days before the November presidential election. That auction got a real yield of 1.670%, lower than today’s result.
Because the coupon rate for this new TIPS was below the real yield of 1.702%, buyers got it at a discounted price of 99.634784. In addition, it will carry an inflation index of 1.00222 on the settlement date of April 30. With that information, we can calculate the exact cost of $10,000 par value at this auction:
- Par value: $10,000
- Principal purchased as of April 30: $10, 022.20
- Cost of investment: $10, 022.20 x 0.99634784 = $9,985.60
- + accrued interest of $6.67
In summary, an investor buying $10,000 par value at this auction paid $9,985.60 and will receive $10,022.20 in principal on the settlement date of April 30.
Inflation breakeven rate
With the 5-year Treasury note trading with a nominal yield of 3.93% at the auction’s close, this TIPS gets a 5-year inflation breakeven rate of 2.23%, a rather low number given our uncertain inflation future. This partly reflects weak demand at this auction, with the real yield rising while the 5-year nominal yield was stable this morning.
Here is the trend in the 5-year inflation breakeven rate over the last 2 years, showing the strong dip in inflation expectations since February:

Thoughts
I knew this 5-year TIPS auction was going to be hard to predict — this is the case with all 5-year TIPS auctions. The October new issue tends to get a real yield lower than “market,” and the April auction in turn tends to get a higher real yield than expected. The reason is the way the non-seasonal inflation affects the final months to maturity of the April issue. Investors expect some deflationary months in the October to December quarter and want a higher real yield as compensation.
So today’s real yield of 1.702% looks good for investors, in my opinion. I was expecting something more in the 1.65% to 1.68% range. It could be that the holiday week and the early auction time contributed to weak demand, resulting in a higher yield.
This TIPS will be reopened at auction on June 17 and then another new 5-year TIPS will be auctioned in October. Here is a history of 4- to 5-year TIPS auctions over the last five years, showing that we’ve come a long way from the -1.685% real yield of the October 2021 auction:

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