It’s almost hard to believe, but this new age of higher interest rates is only about seven months old. A lot has changed in the last year.
Back on Jan. 14, 2022, a 10-year Treasury Inflation-Protected Security had a real yield of -0.66%. In other words, an investor was accepting a return that would trail official U.S. inflation by 0.66% for 10 years. By April 1, that yield had “increased” to -0.41%. By June 1, it was 0.29%. And now, in mid-January 2023, the 10-year TIPS has a real yield of 1.31%, 197 basis points higher than a year ago.
And weirdly, that is a bit disappointing. According to Treasury estimates, the 10-year real yield peaked last year on Oct. 20 at 1.73%. Since then, a series of rather mild inflation reports has the bond market gambling on a Fed pivot, weaker economy and lower mid- to long-term interest rates. So real yields have been sliding lower, bit by bit, in recent weeks.
At the end of last week, we got a little reprieve, following a day of bond market turmoil Thursday triggered by a deflationary December inflation report. As of Friday’s market close, the Treasury was estimating the real yield of a full-term 10-year TIPS at 1.31%, down 22 basis points since the beginning of the year.
All of this points toward Thursday’s Treasury offering of $17 billion in a new 10-year TIPS — CUSIP 91282CGK1. The coupon rate and real yield to maturity will be set by results of the auction, which closes at 1 p.m ET Thursday. This is going to be the first new 10-year TIPS to be auctioned in this new era of higher real yields, and the results will be significant:
- Real yield. If current trends hold (not a sure thing with our current volatility) this TIPS should get a real yield to maturity of about 1.31%. Only two auctions of this term — both late last year — have had a real yield higher than 1% since November 2018, at the very end of the Federal Reserve’s last tightening cycle.
- Coupon rate. A real yield of 1.31% would result in a coupon rate of 1.25%, the highest for any 10-year TIPS since a new issue in January 2011. There have been 72 opening and reopening auctions of this 10-year term since 2011. That is a long time and a lot of auctions. So Thursday’s auction will mark a milestone.
- Inflation index. CUSIP 91282CGK1 will have an inflation index of 0.99948 on the settlement date of Jan. 31. That is because non-seasonally adjusted inflation ran at -0.1% in November. And then … the inflation index will continue to go lower in February, based on -0.31% inflation in December. The big-money investors are going to price this in, trust me. Will that result in a slightly higher real yield than expected? It’s possible.
Definition: The “real yield” of a TIPS is its yield above official future U.S. inflation, over the term of the TIPS. So a real yield of 1.31% means an investment in this TIPS will exceed U.S. inflation by 1.31% for 10 years. If inflation averages 2.2%, you’d get a nominal return of 3.51%, on par with a nominal 10-year U.S. Treasury, currently 3.49%. But if inflation averages 4.5%, you’d get a nominal return of 5.81%.
Here is the trend in the 10-year real yield over the last 15 years. I am showing the “big picture” here because this span includes two recessionary periods, which resulted in Federal Reserve intervention and eventually deeply lower real yields. Are we at the brink of another recession? If so, how will the Federal Reserve react? How long can real yields sustain at relatively high levels? Lots of questions:

As this graph shows, today’s real yields remain close to a 14-year high. Yes, real yields have fallen off a bit, but remain attractive, in my opinion.
Pricing
Because this will be a new TIPS with a positive real yield, the auction is going to result in an unadjusted price that is less than $100 for $100 of par value. That is because the Treasury will set the coupon rate at 1/8-percentage-point below the auctioned real yield. As I noted above, a real yield of 1.31% would result in a coupon rate of 1.25%. A real yield of 1.4% would result in a coupon rate of 1.375%.
Plus, because the inflation index will be less than 1.0, the adjusted price should also be slightly below $100, but there will also be a small amount of accrued interest, probably about 5 cents per $100.
Add it all together and an investor might pay about $99.60 for about $100 of par value, but will end up with about $99.95 of actual principal at the settlement date. That’s a rough estimate, and things will change by Thursday. The key thing for investors is that the cost of the par value you purchase should be very close to par value. No surprises.

Inflation breakeven rate
With a 10-year Treasury note closing Friday at 3.49%, this TIPS would have an inflation breakeven rate of 2.18% if the real yield holds at 1.31%. That seems perfectly reasonable. Inflation over the last 10 years has averaged about 2.6%. I would be more willing to gamble on a 10-year TIPS with a real yield of 1.31% versus a 10-year nominal at 3.49%.
Inflation protection at this point in the cycle isn’t very expensive because the market seems to believe the recent surge in inflation has been tamed. But even if that is so — and I doubt it in the medium-term — projecting future inflation at 2.18% seems like an easy target.
Here is the trend in the 10-year inflation breakeven rate over the last 15 years, showing the surge higher in March 2020 in response to post-Covid stimulus and the gradual move lower beginning in March 2022, as the Fed began to respond to surging inflation:

Final thoughts
I have been targeting this TIPS for purchase for several months because I want to fill a 2033 spot in my TIPS ladder. So I will probably be a buyer, even if real yields decline a bit. But how big a purchase? Should I space out my purchases throughout 2023?
There will be six 10-year TIPS opening and reopening auctions in 2023 — this one in January, and then every other month through November. So investors will have many opportunities. But the key concern is how long real yields can remain at historically high levels. They could certainly go higher, but they certainly could move lower if recession looms.
Let’s look back at January 2019, when the Treasury offered a new 10-year TIPS, CUSIP 9128285W6. At the time, just like now, 10-year real yields had been drifting lower as the auction approached. Using all the wisdom I could muster, I wrote:
“A few months ago, I had targeted this new 10-year TIPS as a purchase, in the hopes of a real yield and coupon rate of at least 1.00%. … Yet, I am committed to adding a 10-year TIPS to my bond ladder sometime during 2019. Hopefully, I can find a higher real yield through the year.”
That January 2019 auction ended up getting a real yield of 0.919% and it was the last “great” auction of 2019, as the Fed began cutting interest rates. I didn’t buy in January and ended up buying no other 10-year TIPS in 2019. Here is how 10-year real yields trended through the rest of that year:

Reality check: I don’t think 2023 is likely follow the pattern of 2019, for several reasons: 1) the Fed is much more committed to holding interest rates at high levels, 2) quantitative tightening will continue throughout the year, and 3) global interest rates are also higher, providing competition to U.S. Treasurys. But toss all that out if the economy moves strongly toward recession.
Conclusion. I will be a buyer Thursday, but I’ll be watching conditions before I make the purchase. That’s my view. If you are considering this TIPS, you can track the Treasury estimates of real yield here, updated daily. Reminder: Anything can happen in the days and hours before a TIPS auction, sometimes good, sometimes bad. The bond market is volatile.
Non-competitive bids at TreasuryDirect must be placed by noon Thursday. If you are putting an order in through a brokerage, make sure to place your order Wednesday or very early Thursday, because brokers cut off auction orders before the noon deadline. I’ll be posting results soon after the auction closes at 1 p.m. ET Thursday.
Here’s a history of 9- to 10-year TIPS auctions going back to 2017, a span that includes the end of the Fed’s last tightening cycle in early 2019. I have highlighted the three auctions with real yields above 1%:
