Use the zero rate to discount a cashflow. The par yield is what makes this curve comparable with a published par curve, the forward is instantaneous rather than a period rate, the money market curve is fitted from bills alone below one year, and the real yield is a return above inflation rather than in cash terms.
What is here
Rates
Key rates from one month to thirty years, zero-coupon, par and money market side by side, with the one-session change, plus the current Series I and EE savings bond rates.
Open Indices
Eleven US Treasury indices, monthly since 2008, free to benchmark against, and built from public data so a published level can be reproduced rather than taken on trust.
Securities
Look up any marketable security priced since September 2, 2008 by its CUSIP; 464 are trading today. Price history and auction results for all of them, plus the measures each family has: yield, duration, DV01 and key rate durations on notes and bonds, discount margin and spread duration on floaters, real yield on linkers.
Curves
Four families fitted every trading day since September 2, 2008: the par curve, the zero curve, a level-slope-curvature factor model, and a money market curve for the sub-one-year segment.
Savings bonds
What a Series I or Series EE bond is worth, and what you would actually receive for it, the twelve-month lock, the three-month interest penalty and the twenty-year doubling guarantee included.
On the Run / Off the Run
The current benchmark issue of every type and term, the securities a headline Treasury yield actually refers to, and the off-the-run issues behind each.
Visualization
Eighteen years of the curve as an animation, every month-end since 2008 drawn against the highest and lowest each maturity has reached. Nominal and real.
Market statistics
Measures of the market itself: how much Treasury debt is held as separate principal and interest, the float our indices deliberately do not deduct, published so the decision can be argued with.
On the run, and off it
Every queue →The on-the-run issue is the most recently auctioned security of its kind and term. It is the one dealers quote and the one a headline "10-year Treasury yield" almost always means. The issues behind it are off the run: nearly identical in coupon and maturity, slightly less liquid, and usually yielding a little more for it.
Notes
Floating rate notes
14 benchmarks across 5 instrument types. A reopening returns its CUSIP to the front of the queue, so a bond first sold years ago can be on the run today.
