Note: I am posting this auction preview early because my I Bond buying guide will be going up Sunday morning. Keep in mind that real yields are currently highly volatile and will change by Thursday’s auction.
The U.S. Treasury on Thursday will offer $22 billion in a new 5-year Treasury Inflation-Protected Security, CUSIP 91282CKL4. The real yield to maturity and coupon rate will be set 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.
As the market stands one week out, it looks like this TIPS will get an attractive result: Potentially both a real yield and coupon rate higher than 2.0%. The Treasury’s 5-year real yield estimate as of the market close Thursday was 2.13%, which would result in a coupon rate at or above 2.0%.
But this market is volatile. Wednesday’s March inflation report reminded everyone that inflationary trends are continuing, and set off a rout in both the stock and bond markets. The 5-year real yield has increased 20 basis points since April 1. That is a huge move higher.
It appears that things are cooling today, with the 5-year TIPS trading at about 2.05%. So a lot can change before Thursday’s auction close at 1 p.m. EDT.
More auction details:
- The Treasury offering of $23 billion is the highest ever for an TIPS auction of this term, up from $21 billion at last April’s auction. The increased supply, however, shouldn’t have much effect on demand.
- The 5-year auction in October 2023 resulted in a real yield to maturity of 2.440% and a coupon rate of 2.375%, both 15-year highs. This auction looks unlikely, at this point, to break those marks.
- If the coupon rate remains above 2.0%, it will be only the 2nd 5-year TIPS in 17 years to reach that mark.
Here is the trend in 5-year real yields over the last nine years:

So there is a lot to like about this TIPS, even in comparison with the U.S. Series I Savings Bond, currently with a real yield of 1.3%. The TIPS will probably have a 70+ basis-point advantage. At that spread, I would prefer the TIPS (but I continue to invest in both.)
Pricing
Because it is a new TIPS, CUSIP 91282CKL4 should auction with a price close to par value. The coupon rate will be set at the 1/8th-percentage-point marker below the auctioned real yield, so the unadjusted price will be below 100. However, this TIPS will have an inflation index of 1.00309 on the settlement date of April 30. Because of that, the price should be close to par, or even slightly above.
Inflation breakeven rate
With the nominal 5-year Treasury note currently trading at 4.54%, this TIPS at this moment would have an inflation breakeven rate of about 2.49%, fairly high by historical standards. A higher breakeven rate indicates that a TIPS is more expensive versus a nominal Treasury.
Is the 5-year note attractive at 4.54%? I’d say it is and it is likely to provide a return above inflation over the next 5 years. But with the TIPS, you get a guaranteed return of about 2.0% above inflation. I’d go with the guarantee.
Here is the trend in the 5-year inflation breakeven rate over the last 9 years, showing that the current level is high-ish, but well under the peak we saw in 2022.

Final thoughts
I just took a look at my 2029 TIPS holdings and I am decently allocated for that year. However … I may take a look at adding a bit at this auction if the real yield is likely to hold above 2.0% (a desirable target by historical standards.)
Things could get crazy in the next week, however, with a potential attack by Iran against Israel looming, oil prices rising, inflation fears growing. In times of fear, Treasury yields generally fall as demand rises. If you want to invest in this TIPS, keep an eye on the Treasury’s Real Yields Curve page (which updates at the close of the market each day) and Bloomberg’s U.S. Yields page (updates secondary-market trends in real time).
This TIPS auction closes Thursday at 1 p.m. EDT. 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 9 years:

It definitely caused at least a small reduction in six-month inflation. What's amazing is if the United States didn't attack…
