FRED documents update notifications, not user-set alerts for a move of a chosen number of basis points.
Track the official daily Treasury curve
Open the Treasury’s Daily Treasury Rates page and select Daily Treasury Par Yield Curve Rates. The table lists rates across published constant maturities, including short-term points and 1-, 2-, 3-, 5-, 7-, 10-, 20- and 30-year maturities. The page also offers CSV and XML downloads.

These constant-maturity Treasury (CMT) rates are points read from an interpolated par yield curve. A 10-year CMT is therefore not necessarily the yield on a particular Treasury bond with exactly 10 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 inputs are not live trade 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.” That describes the quotations used to derive the published rates; it should not be read as an intraday quote.

Get an email when a Treasury series is updated
FRED can notify you when new data are added to a selected series. To set up the notification:
- Find the Treasury series you want on FRED and open its graph.
- Sign in to a free FRED account. An account is required to configure notifications.
- Select Account Tools, then Get email notification.
- To manage or remove a notification later, go to My Account → Notifications.
FRED’s documented trigger is the addition of new data to the selected series—not a threshold you set for a yield move. For example, its notification documentation does not establish an alert that fires only after the 10-year yield rises or falls by a chosen number of basis points.
Choose the series for the maturity you follow
DGS10 is an example for tracking the 10-year constant-maturity rate. FRED describes it as a daily, percent-denominated, not-seasonally-adjusted series sourced from the Board of Governors’ H.15 Selected Interest Rates release. It represents the 10-year maturity, not the entire yield curve. If you want updates on a different maturity, select that maturity’s series rather than treating DGS10 as a proxy for all Treasury rates.

The Federal Reserve Board’s Nominal Yield Curve is a separate way to compare maturities over time. It provides daily estimated curve parameters and smoothed yields on hypothetical Treasury securities, with coverage from 1961 to the present. The Board generally posts updated series once a week, typically on Tuesday for the period through the previous Friday, so it is not the same workflow as a daily Treasury curve page or an email notification when a FRED series changes.

The Board’s curve is model-based and constructed differently from Treasury’s published par curve. Its model uses coupon securities (notes and bonds), but not Treasury bills or floating-rate notes, and excludes on-the-run and first-off-the-run notes and bonds. Treat the two curves as distinct views, not interchangeable readings from identical inputs.
