The U.S. Treasury’s $8 billion reopening auction today of CUSIP 912810SV1 generated a real yield to maturity of -0.292%, the lowest ever for any TIPS auction of this term.
The auction created a 29-year, 6-month Treasury Inflation-Protected Security, carrying a coupon rate of 0.125%, the lowest the Treasury will go for any TIPS. .
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.
Because the auction’s real yield to maturity was so far below the coupon rate of 0.125%, investors at Thursday’s auction had to pay a lofty premium over par for this TIPS. The adjusted price was about $117.72 for about $104.33 of value, after accrued inflation is added in.
This TIPS will carry an inflation index of 1.04326 on the settlement date of Aug. 31. That means investors paid an extra 4.3% above par, but will receive a matching amount of inflation adjustment. The unadjusted price — reflecting just the real yield versus coupon rate — was about $112.84 for $100 of par value.
Here is the trend in 30-year real yields over the last two years, showing the dramatic move lower in the wake of the Federal Reserve intervention beginning after the COVID-19 surge in March 2020 and continuing today:
Inflation breakeven rate
With a 30-year nominal Treasury yielding 1.88% this afternoon, this TIPS gets an inflation breakeven rate of 2.17%, which looks entirely reasonable. U.S. inflation over the last 30 years has averaged 2.3%, the lowest for any 30-year period beginning with 1971. So today’s breakeven number looks pretty attractive by historical standards.
Here is the trend over the last two years in the 30-year inflation breakeven rate, showing that inflation expectations have been leveling off after a surge higher through most of 2020 and into the spring of 2021:
Reaction to the auction
CUSIP 912810SV1 trades on the secondary market, and had been trading with a real yield to maturity of 0.30% through the morning. So the auction result looks just about right. Close enough, anyway. The TIP ETF — which holds the full range of maturities — took a bounce higher after the auction close, which indicates a positive reaction to the auction.
A 30-year TIPS is a unique investment with little appeal to small-scale investors. The Treasury reported that only $2.9 million — that’s million — of the $8 billion offering was sold through TreasuryDirect. In all, only $5.6 million was purchased through non-competitive bids, the only option open to small-scale investors.
The auction’s bid to cover ratio was 2.34, not stellar but acceptable.
For big-scale investors — like foreign central banks, hedge funds and pension funds — the relatively low inflation breakeven rate was enough to make this TIPS appealing, at least versus a 30-year nominal Treasury yielding 1.88%.
This auction closes the books on CUSIP 912810SV1, the only 30-year TIPS in history to get a coupon rate of 0.125%. Here the history of 29- to 30-year TIPS auctions from 2018 to 2021:
