Amount outstanding: $10.86bn
Held stripped: $1.17bn
Share stripped: 10.74%

Stripped par is held as separate interest and principal components rather than as whole securities. The Safe Rate indices deliberately do not deduct it, and the whole-market figure is published so that decision can be argued with. Market statistics.

Amount outstanding as reported by Treasury, in its Monthly Statement of the Public Debt. The Safe Rate indices weight on a different figure, float-adjusted original par, and the two are not comparable security by security. The index figures are published per holding.

Risk, November 10, 2026

Yield to maturity: withheld
Modified duration: 0.008 yr
DV01: 0.0001
Convexity: 0.00000132
Dirty price: 103.041

Yield and duration are withheld this close to maturity, not missing. Inside a month a Treasury trades on settlement mechanics rather than on yield, and its price is a rounding of par, annualizing a two-day stub produces a number in the tens of percent that would be arithmetically correct and completely misleading. The price, the residual and the key rate durations below are unaffected.

Sensitivity to a one basis point move at each point on the curve, in years. All of it sits at 3M. For a security with a single remaining cashflow that is the true shape, not missing data.

Against the fitted curve

Priced 17.37 cents per 100 of face cheap to the curve on that day.

Shown as a price rather than a yield. This security was close enough to maturity that annualizing is meaningless, the same reason it carries no yield to maturity above, and the same difference quoted in basis points would read as an enormous mispricing rather than the few cents it is.

Prices are per 100 of face, from Treasury's own end-of-day file. A dash means that side was not quoted that day, which is almost always the offer and almost always near maturity: a holder of a bill days from paying par has little reason to sell it.

Auction

A CUSIP can be auctioned more than once: Treasury reopens an existing security rather than issuing a new one, so the same bond is sold again at whatever yield the market then wants.
