The U.S. financial markets have had an interesting two weeks, to say the least. An active war in the Mideast has sent oil prices soaring, the stock market tumbling, and the U.S. bond market into turmoil.

U.S. inflation is very likely to rise in the short term, and possibly for the longer term. Billions of new borrowed money is flowing into attacks on Iran, causing longer-term Treasury yields to rise. Then, add in the cost of billions of upcoming tariff refunds to corporations. At the same time, the U.S. economy appears to be slowing and the Fed’s favorite inflation measure — core PCE — has risen to a too-high 3.1% as of January. The markets have a new fear: “stagflation.”

That’s the backdrop for Thursday’s Treasury auction of $19 billion in a reopened 10-year TIPS — CUSIP 91282CPU9 — creating a 9-year, 10-month TIPS. This TIPS had its originating auction Jan. 22, 2026, which generated a real yield to maturity of 1.940% and set its coupon rate at 1.875%.

For a while, that January auction looked like a big win for investors, as the 10-year real yield dipped to as low as 1.72% on February 27, one day before the U.S./Israel attack on Iran. Now two weeks later, CUSIP 91282CPU9 is trading on the secondary market with a real yield of 1.90%.

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 1.90% means an investment in this TIPS would provide a return that exceeds official U.S. inflation by 1.90% for 9 years, 10 months.

In times of international strife, you would expect to see a “flight to safety” causing investors to pour into U.S. Treasurys. In addition, we could expect TIPS to be in higher demand because of the fear of future inflation. So far, that is not happening.

You can track CUSIP 91282CPU9’s real yield and price on Bloomberg’s Current Yields page, which updates in real time when the bond market is open. It closed Friday with a real yield of 1.90% and a price of 99.82. I would expect to see a lot of volatility leading up to Thursday’s auction.

Here is the trend in the 10-year real yield over the last 16 years:

I start this chart in 2010 for a reason: It is a year before the Federal Reserve began aggressive quantitative easing in mid 2011 and then again in 2020 in the aftermath of the COVID shock. Today’s 10-year real yield of about 1.92% (the current Treasury estimate for a full-term TIPS) is attractive from this longer-view perspective. But investors should be aware that real yields could certainly rise from this point.

Pricing

If we assume the auction’s real yield will be 1.90% (things will change by Thursday) this TIPS is likely to auction at or near par value, since that yield is a bit above the coupon rate of 1.875%. The Bloomberg yields page shows a Friday closing price of 99.82. Plus, this TIPS will carry a minimal inflation index of 1.00086 on the settlement date of March 31. Let’s look at how that works out for a $10,000 par value investment:

• Par value: $10,000.
• Principal purchased on settlement date: $10,000 x 1.00086 = $10,008.60
• Cost of investment: $10,008.60 x 0.9982 = $9,990.58
• + accrued interest of about $33.88.

Things will change by the auction, but this one is likely to cost near par value. The accrued interest will be returned at the first coupon payment on July 15.

Inflation breakeven rate

I have been assuming that inflation expectations would rise because of the current oil shock, but possibly not so much for 10 years out. This chart shows the 10-year inflation breakeven rate has increased 11 basis points since the outbreak of war.

An inflation breakeven rate of 2.36% is high by historical standards, meaning that the TIPS is getting expensive versus a nominal 10-year Treasury note. However, it seems in line with current conditions. Inflation has averaged 3.3% over the last 10 years, ending in February.

Here is the trend in the 10-year inflation breakeven rate over the last 16 years, showing the relative stability of expectations since fall of 2022:

Thoughts

I was a buyer of this TIPS in January, purchasing my entire 2036 allocation at that auction. So I won’t be a buyer this week. For investors, a real yield hanging in the 1.90% range looks attractive, in my opinion. But this week will be volatile, and any investor would be wise to watch the Current Yields page for updates.

This TIPS can be purchased at any time on the secondary market, which gives investors the option to target a desired yield.

The advantage of buying at auction, especially through TreasuryDirect, is that even small-lot purchases will get the auction’s high yield. The advantage of the secondary market is that you can see exactly the price and real yield you will be receiving. The negative is that you may face a small bid-ask spread. Most of the time, it doesn’t make a huge difference, but if you see a real yield you like, know that you can probably get it on the secondary market without dealing with the auction’s uncertainty.

This TIPS auction closes Thursday at 1 p.m. ET. 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 will be posting the auction results soon after the close on Thursday. Here is a history of auction results for this term over the last 5 years:
