The U.S. Treasury, at 1 p.m. Thursday, will auction $13 billion in a new-issue 10-year Treasury Inflation-Protected Security, Cusip 912820YP6.
Buy it: Yes or no? I say no. Here is Tuesday’s quote for the 10-year TIPS that will mature in January 2021, six months before this new issue will mature:

0.479%, not good enough. Does this real yield, 0.479% above the rate of inflation, look appealing? It does not.
The yield has fallen dramatically in recent weeks. The 10-year TIPS auctioned in May went at a yield of 0.887%, hardly wonderful, but much better than 0.479%. On June 29, three weeks ago, the market yield was at 0.676%. Amazing.
This auction could threaten a record-low yield for a 10-year TIPS. Here are the auction yields for every 10-year TIPS ever issued or reissued:

I highlighted the record low yield, 0.409% in November 2010, and the record high yield, 4.25% in January 2000. It’s worth noting that only three auctions, all recent, have ever gone under 1%.
Of course, we don’t know what kind of appeal Thursday’s issue will have. But I can’t imagine high demand at a time when the Treasury is facing a threat of default (unlikely, I hope) in 12 days. In addition, this is the first recent TIPS auction without the artificial demand of QE2. Maybe the yield will end up substantially higher. But as I have said before … don’t fool yourself into thinking you can predict a TIPS auction.
Still wavering? Thursday morning, recheck that Jan 2021 yield on the Barron’s chart. TIPS had a crummy day Wednesday, with the TIP ETF falling 0.57%. The 10-year yield likely rose nicely. Make the call after seeing the closest market yield.
Update: Wednesday’s yield to maturity for the Jan 2021 TIPS closed at 0.550%, up substantially. This could be an very interesting auction today. The coupon rate would likely be 0.5% and the TIPS could go at a slight discount to par.
This is the last new issue of the year, but you will get several more chances to buy reissues; in fact, there is an auction every month of this year. Ten-year reissues will come up in September and November.
And, of course, your first $5,000 (or $10,000 or $20,000, depending on if you mix paper and electronic purchases) should be in I Bonds, anyway, if you haven’t invested in them this year.
Would this 10-year TIPS be a horrible investment? No, it would be fine. Here’s the thing: Do your thinking about TIPS before you buy. After you buy, forget it. If you are holding to maturity, you will do fine. Buy it and forget it.
I've been rolling over my bonds on a five year cadence, but waiting until the five years are up.
