U.S. 2-year Treasury yield

Reading the latest movement

For Sep 28, 2026, this snapshot reports 4.92 percent per year in the published level view. The difference from the preceding available period is 0.11 percentage points. This comparison uses the prior value contained in the same acquired file. A difference between periods describes economic change; it is separate from a later revision of either observation.

Definition and limitations

Published reference observation, not an executable quote or a rate offered to individual borrowers. Nonbusiness days and unpublished values remain gaps. Constant-maturity yields are interpolated from the Treasury yield curve.

Percentage growth is calculated from matching series levels. Both endpoints retain the same adjustment basis. Growth computed from rounded source inputs can differ from the agency’s published headline rounding.

Transformations and related measures

Published level retains the source unit. Year-over-year change compares with the same reference period one year earlier. Weekly series compare with 52 weeks earlier (364 days) to retain the weekday. Previous-period percentage change measures the relative change; absolute change subtracts the preceding level. For a rate already expressed in percent, absolute change is in percentage points. Invalid or missing denominators produce an unavailable result. No frequency conversion or hidden rescaling is applied.

Revisions and archived snapshots

Two site acquisitions are archived. Matching unchanged series identities can be compared between versions; this is not a complete agency vintage history. Previous-period readings above come from the same acquired snapshot. The revision comparison separates changes to matching historical observations from new coverage and corrected series identities. Earlier agency vintages remain outside this archive. Read the revision policy and download this frozen snapshot.
