Here’s a strange fact: Despite the surge higher in 10-year real yields over the last 16 months, no new-issue TIPS of this term has received a coupon rate of 1.50% or higher since July 2009. That’s true even though daily 10-year real yields crossed the 1.50% threshold in September 2022 and hit a peak of 2.52% on Oct. 25, 2023.
It is just the way the January and July auctions have turned out for this 10-year term. In January 2023, real yields dipped to about 1.22% (the auction got a coupon rate of 1.125%) and then in July 2023, down to 1.49% (the auction got a coupon rate of 1.375%).
This trend might be broken Thursday, when the Treasury auctions a new 10-year TIPS, CUSIP 91282CJY8. The real yield to maturity and coupon rate will be determined by the auction results.
Definition: 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 inflation each year until maturity.
Some thoughts about CUSIP 91282CJY8:
- This will be the only TIPS — up to this point — maturing in 2034. A second will be created in the July 2024 auction of another new 10-year TIPS.
- The Treasury set the auction size at $18 billion, the largest in the 26-year history of 10-year TIPS. Will the market comfortably soak up that additional supply? The Treasury seems at least a little concerned, based on a recent Reuters report.
- This TIPS will have an inflation index of 0.99896 on the settlement date of Jan. 31 because of slightly negative non-seasonally adjusted inflation in November. Principal balances will also decline 0.1% in February, based on December inflation. Big money investors will be adjusting their bids based on these facts.
Real yields have been volatile over the last week, but at this point the Treasury’s estimate for a full-term 10-year TIPS is a real yield of 1.69%, down 14 basis points in a week. The most recent 10-year TIPS trading on the secondary market closed Friday at 1.66%.
It’s impossible to say where we are heading into next week. Tensions are building yet again in the Middle East. China isn’t happy with Taiwan’s election. The U.S. Congress may sink toward another government shutdown, while deficits continue surging higher. Plus, markets are closed Monday for the Martin Luther King Jr holiday.
The result is volatility, but we are used to that.
So let’s assume that this TIPS gets an auctioned real yield of 1.69%. That would be the 3rd highest real yield for this term since April 2010, but well below recent reopening auctions of this term: 2.094% in September 2023 and 2.180% in November 2023. The coupon rate would be set at 1.625%.
Exciting? Not really. Disappointing? No. It is what it is, a historically attractive real yield for a 10-year TIPS. Here is the trend in the 10-year real yield over the last 15 years:
Pricing
Because this is a new TIPS, the coupon rate will be set to the nearest 1/8th percentage point below the auctioned real yield. That means the TIPS will have an unadjusted price below 100. Add in the fact that the inflation index will be 0.99896 on the settlement date, and you have a near guarantee that this TIPS will auction with an adjusted price below par value of 100. The only unknown factor is a small amount of accrued interest based on the as-yet-undetermined coupon rate.
What does this mean? If you are placing an order for this TIPS at auction, you can be fairly certain your cost will be very close to or below par value. That makes things easy. If you want $10,000 par, the price should be right around $10,000, either at TreasuryDirect or any brokerage that doesn’t charge a commission.
Inflation breakeven rate
With the Treasury estimating the yield on a 10-year nominal Treasury note at 3.96% on Friday, CUSIP 91282CJY8 currently would have an inflation breakeven rate of 2.27%, which aligns closely with recent auctions of this term. This looks very reasonable to me. Here is the trend in the 10-year inflation breakeven rate over the last 15 years:
From this chart, which shows recessions in shading, you can see that the inflation breakeven rate drops drastically when economic distress strikes. Those are opportune times for investing in TIPS, at least versus a nominal Treasury. As those times worsen, the Treasury generally steps in with quantitative easing, and TIPS investments benefit.
Right now we are in more of a neutral zone. The Fed is still doing quantitative tightening, which means it is lowering its $4.7 trillion balance sheet of Treasurys. But there have been indications QT could end this year. If that happens, TIPS yields could decline along with nominal yields.
Is this TIPS a ‘must buy’?
Although I am planning to buy a sizable investment Thursday, I wouldn’t call this auction a must buy. That will depend on something we can’t know: the future. 1) If you think real yields will be heading steadily lower in 2024, then buy at this auction. 2) If you want to fill a 2034 slot on your TIPS ladder for an investment that will be held to maturity, then buy at this auction. (Or soon after on the secondary market.)
But if you think real yields will be in flux through the year, then you will have plenty of opportunities to buy on the secondary market or at two more reopening auctions for this TIPS (in March and May) and then a new TIPS in July and two more reopenings later in the year.
However, keep in mind that finding CUSIP 91282CJY8 on the secondary market in small lot sizes could be difficult for a few weeks, even more than month.
I Bonds vs. TIPS?
The U.S. Series I Savings Bond currently has a permanent fixed rate of 1.3% for purchases through April. It appears CUSIP 91282CJY8 will have about a 39-basis-point advantage, which I think makes this competition a toss up. I Bonds have a lot of advantages over TIPS, but purchases are limited to $10,000 per person per year unless you use your tax return to get paper I Bonds or add to your holdings through the gift-box strategy or trusts.
As things stand, I definitely plan to buy I Bonds up to the limit this year, very probably in April. After that, I will strategically add to my TIPS holdings. The two investments are compatible — I Bonds for future cash needs and TIPS for defined inflation-protected payouts in future years.
What’s next?
This TIPS auction closes Thursday at 1 p.m. EST. 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.
You can track the Treasury’s daily yield estimate after the market close each day on its Real Yields Curve page. But remember that the bond market is closed Monday. I hope to post the results soon after the auction closes on Thursday.
