Field Notes, Volume Zero
This is a public data journal. The idea is simple enough: I spend time downloading, parsing, and analyzing financial datasets, and instead of letting those notebooks sit in a folder on my laptop, I put them here.
What you’ll find here
Mostly credit markets. The kind of data that shows up in analyst reports as a single chart with a footnote that says “Source: Federal Reserve.” I’m interested in where those numbers come from and what the raw data actually shows when you look at it directly.
The main datasets right now:
- ABS-EE — loan-level auto credit data from SEC EDGAR securitization filings
- SLOOS — the Federal Reserve’s survey of bank lending standards
More as the pipelines get built.
What this isn’t
Not financial advice. Not a trading signal service. Not trying to have takes. The analysis here is descriptive — here’s what the data shows, here’s the methodology, here’s where it’s incomplete. Conclusions are, per the tagline, questionable.
How the charts work
The dashboards on this site are built from pre-aggregated Parquet snapshots. Data lives in a private Cloudflare R2 bucket; aggregation scripts run at deploy time and embed the results directly into each page. Interactive charts run in your browser via Observable Plot — no backend server, no live queries.
The ingestion pipeline that powers this site is private. If you’re interested in the data or the pipeline, get in touch: [email protected]
That’s it. More notes when there’s something worth writing.
