Reflecting a trend of both rising real yields and rising inflation expectations, the U.S. Treasury’s reopening auction today of a 10-year Treasury Inflation-Protected Security — CUSIP 91282CBF7 — generated a real yield to maturity of -0.580%, an expected result that was higher than recent yields for this term.
This TIPS was created in an originating auction on Jan. 21, 2021, with a record low real yield to maturity for this term, -0.987%. Today’s auction result was 38 basis points higher, a big move in just two months.
A TIPS is an investment that pays a coupon rate well below that of other Treasury investments of the same term. But with a TIPS, the principal balance adjusts each month (usually up, but sometimes down) to match the current U.S. inflation rate. So, the “real yield to maturity” of a TIPS indicates how much an investor will earn above (or below) inflation.
CUSIP 91282CBF7 carries a coupon rate of 0.125%, the lowest the Treasury will allow on a TIPS. Because the auctioned real yield to maturity was well below the coupon rate, buyers at today’s auction had to pay a premium price — about $107.62 for about $100.73 of value, after accrued inflation and interest is added in. This TIPS will have an inflation index of 1.00473 on the settlement date of March 31.
But today’s price was well below the $111.64 cost of the originating auction, which reflects the big increase in real yields over the last two months.
It looks like the auction went off as expected, in line with the trend of overall increases in both real and nominal yields. At mid-morning, CUSIP 91282CBF7 was trading on the secondary market with a real yield of -0.59%, close to the auction result. So, no surprises. However, the bid-to-cover ratio was 2.42, a middling number that reflects decent, but not strong, demand.
Here is the trend in 10-year real yields over the the last two years, showing the brief bounce higher a year ago during pandemic-related market turmoil, and then a deep decline amid economic gloom, and the gradual rise higher since the beginning of 2021 as COVID vaccines were rolled out and Congress approved economic stimulus packages:

This recent rise in yields is driving prices lower for broad-based TIPS mutual funds and ETFs. The TIP ETF is trading down about 0.6% today at a price of $124.81, indicating higher market yields. But today’s auction had little effect on the price, which indicates the result matched expectations.
Inflation breakeven rate
With a nominal 10-year Treasury trading at the auction close at 1.73%, this 9-year, 10-month TIPS gets an inflation breakeven rate of 2.31%, a big surge higher than numbers from similar auctions over the last year:
- March 19, 2020: 0.43%
- May 21, 2020: 1.14%
- July 23, 2020: 1.52%
- Sept. 17, 2020: 1.65%
- Nov. 19, 2020: 1.72%
- Jan. 21, 2021: 2.09%
- March 18, 2021: 2.31%
Investors are “all-in” in committing to higher future U.S. inflation, given the Federal Reserve’s commitment to continued economic stimulus, combined with the lofty cash payments and credits to individuals included in the newest economic package passed by Congress. But these same forces are driving both nominal and real interest rates higher.
Inflation has been running at 1.7% over the last year, and has averaged 1.7% over the last 10 years. Will inflation move dramatically higher, as the market is predicting? It could happen, but I am thinking the 2.31% inflation breakeven reflected in this auction could be nearing a top, at least until we start to see actual higher inflation in the United States. Future inflation is nearly impossible to predict.
Here is the trend in the 10-year inflation breakeven rate over the last two years, showing the dramatic climb higher from the market depths of March 2020:

What’s ahead?
Today’s auction was the first of two reopenings for CUSIP 91282CBF7. The Treasury will offer another reopening in May, and then offer a new 10-year TIPS in July.
Next month’s offering will be a new 5-year TIPS, with the auction on Thursday, April 22.
