Use the U.S. Treasury’s Daily Treasury Rates page to follow its official daily par yield curve, and use FRED email notifications to hear when a selected Treasury-yield series gets a new observation. FRED’s documented notification is an update alert—not a verified alert for a user-set move such as a 10-year yield changing by a chosen number of basis points.
Track the official daily Treasury yield curve
Open the U.S. Treasury’s Daily Treasury Rates page and select Daily Treasury Par Yield Curve Rates. The page presents rates at published constant maturities, including short-term points and 1-, 2-, 3-, 5-, 7-, 10-, 20-, and 30-year maturities. It also provides CSV and XML downloads.
These constant-maturity Treasury (CMT) rates are points read from an interpolated par yield curve. A 10-year CMT rate is therefore not necessarily the yield on a specific Treasury bond with exactly ten years remaining. Treasury describes the curve as based on closing market bid prices for the most recently auctioned Treasury securities in the over-the-counter market.
The quotations behind the curve are not live transaction prices. Treasury says: “These par yields are derived from indicative, bid-side market price quotations (not actual transactions) obtained by the Federal Reserve Bank of New York at or near 3:30 PM each trading day.” Use the published rate as a daily curve observation, not as an intraday quote or the yield of a particular bond.

Set a FRED email notification for a yield series
FRED can email you when new data are added to a series. You need a free FRED account to configure the notification.
- Find the Treasury-yield series you want to monitor in FRED and open its graph.
- Sign in to your FRED account.
- Choose Account Tools, then Get email notification.
- To manage or remove alerts later, go to My Account → Notifications.
FRED’s notification help page describes an email when new observations are added to the selected series. It does not document a configurable threshold trigger for a move of a chosen number of basis points or percentage. If you need that kind of alert, verify the feature and its current settings with a service that explicitly supports threshold-based yield alerts.

Example: follow the 10-year constant-maturity rate
DGS10 is FRED’s daily, percent-denominated, not-seasonally-adjusted 10-year constant-maturity series. Its metadata identifies the Board of Governors’ H.15 Selected Interest Rates release as its source. It tracks the 10-year point, not the entire Treasury curve. For another maturity, select the corresponding series instead of treating DGS10 as a proxy for all maturities.

The Federal Reserve Board’s Nominal Yield Curve offers a different view: daily estimated curve parameters and smoothed yields on hypothetical Treasury securities, with coverage from 1961 to the present. The Board says it generally posts updates once per week, typically on Tuesday for the period through the previous Friday. That makes it useful for model-based historical comparisons, but it is not the same as the Treasury’s daily par curve or FRED’s email notification workflow.
The Board’s model uses coupon securities—notes and bonds—but not Treasury bills or floating-rate notes. It also excludes on-the-run and first-off-the-run notes and bonds. Because the Board’s smoothed model curve and Treasury’s published par curve are constructed differently, treat them as distinct measures rather than interchangeable readings of identical inputs.
