The US Treasury yield curve and CPI, ready to load in one file
Curvewire merges the US Treasury daily par yield curve (1990 to today, with 10y-2y and 10y-3m spreads), the real TIPS curve since 2003 and 15 headline BLS series (CPI, core CPI, payrolls, unemployment, JOLTS, PPI with 1- and 12-month changes) into three tidy Parquet tables. One download, no key, CC0. Want the week's moves on one page instead of a table? The Curvewire Brief does that every Monday.

Why teams pick Curvewire
- The whole history in one download: 1990 to today, not one year per CSV as on treasury.gov.
- Spreads (10y-2y, 10y-3m) and 1- and 12-month changes are already computed.
- Treasury and BLS in one tidy shape; no FRED key and no BLS 25-queries-a-day limit.
- The Monday brief at $19/month is a fraction of a $129.99/month markets letter, and it ships the CSVs and the script behind every number.

Is there a free download of historical Treasury yields?
Yes. Curvewire has every daily par yield curve since 1990 (9,189 curve days in the 24 Sep 2026 build) as one Parquet or CSV file, CC0, no key.
Why not FRED?
FRED is great for browsing and charts. Its API needs a registered key and series come one at a time; Curvewire keeps only public-domain Treasury and BLS series and ships the spreads and changes precomputed in one file.
Why not The Kobeissi Letter?
It is a markets newsletter with commentary at $129.99/month. The Curvewire Brief is $19/month and sticks to the numbers: curve, spreads, real yields and BLS data, with the CSVs.
How fresh is it?
The dataset is a snapshot refreshed when the sources change; the latest build covers the curve to 23 Sep 2026. For a fresh view every week, the brief is rebuilt each Monday.
Do I have to pay to use it?
No. The data keeps its open licence for everyone, at work too. The $49/year licence is for companies that want an invoice, a certificate in their name, named support and service levels; it covers every CyberMax dataset.
Is this investment advice?
No. Public US government data, reformatted. Information only.
