Still priced, no longer analyzed. Risk numbers below are as of Jun 2, 2026, analytics stop about three months before maturity, because a security with one cashflow left does not have a meaningful yield curve exposure.

Where its rate sensitivity sits

All of it in one place. A bill pays a single cashflow at maturity, so its key rate profile is its modified duration of 0.003 years, sitting in the nearest bucket and nothing anywhere else. That is also why its duration equals its remaining term rather than being shorter: there are no coupons to pull the average payment date forward. A twelve-bucket chart of that would be eleven empty bars.

Against the money market curve

Priced 0.01 cents per 100 of face cheap to the curve on that day.

Shown as a price rather than a yield. This bill is 2 days from redemption, and inside a month the difference between its price and the curve annualizes into a number that looks like an enormous mispricing rather than the fraction of a cent it is: worst case across eighteen years, 1,435 basis points on a residual of four cents. Its yield above is unaffected and stands: a bill quotes on an investment-rate basis, which is the market's own convention rather than an annualized stub.

3 auctions

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.

The curve this was priced against →

Index levels before September 30, 2026 are back-tested. They were computed after the fact by applying the rules to historical data, which benefits from hindsight in the choice of rules, and an index cannot be invested in directly. Methodology v1.0 takes effect at that rebalance, when levels begin to be struck on the day; the rulebook is identical either way, and the version is published on every row.

A fitted curve is a fit, not a quote. Daily error averages 3.8 basis points across the history and reaches about 20 on the worst days, in December 2008, when the market was genuinely hard to fit one smooth curve to. Every curve page publishes its own fit error rather than burying it.

Free to benchmark against. Paid only to track. Measuring anything against these curves and indices is free. No license, no fee, no registration, and no permission needed to say that you did, including in a prospectus. A fee applies to one thing: launching a product that tracks an index.
