Treasury Yield Curve

About this dataset

Treasury Yield Curve is a Public dataset in the Rate Environment group of the BankRegReports Data API. The response carries 4 documented fields, sourced from US Treasury.

The Treasury yield curve in long form; pivot client-side for any tenor slice or curve animation. Pass `?latest=1` for just the most recent curve (≈12 tenor rows). Pass `?tenor_code=Y10` to get a daily single-tenor series. `since`/`until` filter on `rate_date`.

When to use it

Treasury Yield Curve sits in the Rate Environment group of the Data API. Reach for it when your work needs this data straight from the API: it comes back as JSON you can load into a notebook, a spreadsheet or a scheduled pipeline, with the dataset key yield_curve naming it the same way in the REST path, the Python SDK and the OpenAPI document.

Access and authentication

This dataset is in the Public tier. Send your API token in the Authorization header as a Bearer token, using a GET request to the endpoint above. The Free plan is the first plan that includes it.
