A floating-rate note resets quarterly against the 13-week bill, so it has no yield to maturity: the cashflow schedule a yield would describe does not exist. What it has instead is a spread, the margin a buyer earns over that reference rate, and a sensitivity to that spread rather than to the level of rates.

Rate duration is almost zero, and that is the instrument rather than a missing number: because the coupon resets, the price barely moves when the level of rates moves. Spread duration is the one that matters here. It says how much the price moves if the market demands a wider margin.
Its current margin is 1.12 standard deviations from its own typical margin.

Prices are per 100 of face, from Treasury's own end-of-day file. A dash in the bid or offer column means none was posted that day.

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.
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.
