The US Treasury hasn’t posted the formal announcement yet (it will be coming later this morning), but we know it will auction a new 10-year Treasury Inflation-Protected Security on Thursday, July 24. It will be CUSIP 912828WU0, and because this is a new issue, both the coupon rate and yield to maturity will be set when the auction ends.
Advantage of a new issue. Some TIPS followers don’t like the uncertainty of buying at auction, especially reopening auctions, because the price they pay can vary from what they expect. This happens when the yield to maturity is well above or below the coupon rate. This happens with reopenings, and the price swings can be dramatic (while somewhat predictable for those who follow the market).
But with a new issue, when the yield to maturity is above zero, the Treasury always sets the coupon rate one ‘click’ below the yield to maturity, meaning that buyers should be getting the TIPS at a slight discount, or at least extremely close to par after accrued interest is added in. The last two new-issue 10-year TIPS auctions demonstrate this:

Disadvantage of a new issue. While there is less uncertainty about the dollar amount you will pay, a new issue isn’t currently trading on the secondary market and thus has no set coupon rate. Until the auction ends, you won’t know the coupon rate, or the yield to maturity, and this can be hard to predict for new issues. A new issue creates added ‘inventory’ for the TIPS market, and the pricing at auction can be slightly volatile.
What we know today about CUSIP 912828WU0. It’s possible that this new TIPS will auction with the lowest yield to maturity for any 9-to 10-year TIPS since May 2013, when the yield was -0.225%. Since then – for six consecutive auctions – the lowest yield to maturity has been 0.339%. Next Thursday’s yield could be lower:
- Bloomberg’s Current Yields page is flashing a yield of 0.25% for a less-than 10-year TIPS currently trading on the secondary market.
- The Wall Street Journal’s closing price chart is showing that a TIPS maturing Jan. 15, 2024, closed yesterday at 0.285%.
- The Treasury’s Real Yield Curve chart – which estimates the price of a full-term 10-year TIPS – is showing a yield of 0.32% at the close Wednesday.
A lot can happen in a week, especially with a new issue, but right now we are looking at a yield of maybe 0.285% to 0.325% for this TIPS, and a coupon rate of 0.25%. The last new issue 10-year TIPS – auctioned Jan. 14, 2014 – went off with a yield of 0.661% and a coupon rate of 0.625%.
That’s a drop of more than 30 basis points in half a year, and it makes a big difference in the secondary market value of that TIPS. The January TIPS auctioned with a price of $99.548 per $100 of value, but now is much more expensive – about $103.15 on the secondary market. This price swing will work in reverse if (when?) interest rates begin to rise.
The inflation factor. One factor driving demand for TIPS – which causes yields to decline – is that inflation has been steadily rising this year. On top of the coupon rate, the principal balance of TIPS rises with the Consumer Price Index for all Urban Consumers (CPI-U). I chart recent inflation rates on my I Bonds page.
Inflation is currently running at 2.1% over the last 12 months. However – and this is crucial for buyers at next Thursday’s auction – the June 2014 inflation number will be announced Tuesday at 8:30 a.m. That number could have an effect on TIPS prices. Wait to see that number, and the reaction in TIPS prices, before making a buying decision.
Inflation breakeven rate. With the nominal 10-year Treasury closing yesterday at 2.55% and a 10-year TIPS at 0.32%, this creates a 10-year inflation breakeven rate of 2.23%. This means that if inflation averages more than 2.23% over the next 10 years, a TIPS will outperform at traditional Treasury. Back in January, the last new TIPS auction generated a breakeven rate of 2.12% — more attractive, in my opinion.
In summary, next week’s TIPS auction is not looking like an attractive buying opportunity. If you believe interest rates will be rising in the next few months, you will have an opportunity to get this same TIPS at a discount at reopening auctions in September and November. On the other hand, if you believe inflation will continue to rise without interest rates rising, this issue could be appealing.
Here is a chart of recent 9- to 10-year TIPS auctions showing how yields have risen from negative levels of 2012 to 2013, but remain well below historical norms:
