/* Document-grade card styling: structural rules only, no decorative treatment.
   Two deliberate constraints, both learned the hard way on this account:
   (1) no background is set anywhere, so the card inherits the Hub's own text colour and stays
       legible in both themes. The previous skin forced a dark ground and a neon palette on every
       heading, rule and table; HF strips @media from card <style> blocks, so a forced palette
       could never adapt to light mode.
   (2) rules use a translucent grey rather than a fixed colour, so a hairlines sits correctly on
       either background. Nothing here computes or restates a figure. */

# Dragon Finance — rates

**stored:** 65.62 MB  ·  **shards:** 21  ·  **class:** rates  ·  **sources:** US + global official

US sovereign rates and public finance — the risk-free curve and federal cash flows.

Part of the **Dragon Finance Corpus** — public financial data from US federal agencies, world
official institutions and public registries. Nothing licensed, paywalled or registration-only.

Front door: [`Dragon-Finance-Corpus`](https://huggingface.co/datasets/dragonlimited/Dragon-Finance-Corpus)
— every card, the chunked corpus and the derived artefacts, all measured from the hub;
[collection](https://huggingface.co/collections/dragonlimited/dragon-finance-corpus-6ae5fbf5e8d41b80f0ca44f0)
— this repo and its siblings.



## Coverage

| | |
|---|---|
| Yield curve | Treasury daily yield curve, all maturities |
| Auctions | auction results via the Treasury fiscal API (auctions_query) |
| Fiscal | Treasury fiscal data: debt to the penny, average interest rates, interest expense |
| Money-market rates | NY Fed reference rates and SOMA holdings |
| Eurozone | ECB yield-curve and bank interest-rate flows |

## Size

| metric | value |
|---|---|
| stored | **65.62 MB** |
| shards | 21 |
| **training-ready tokens** | **0.4 M** (0.01% of the chunked corpus) |

## Training-ready text

Measured 2026-11-04 18:38 UTC over 48 of 48 shard(s). Tokens use the one convention these cards share - `chars / 4` over the chunked text - so each figure is reconcilable against the shards.

| source | chunks | text | tokens | share |
|---|---:|---:|---:|---:|
| `treasury` | 1,500 | 0.001 GB | 0.4 M | 0.00% |
| `treasury_fiscal` | 108 | 0.000 GB | 0.0 M | 0.00% |
| `bankofengland` | 6 | 0.000 GB | 0.0 M | 0.00% |

Class attribution uses the shard path's first segment, so a tier that shares a segment with
another class (`census`, `federalreserve`, `sec`) is attributed to its dominant class.

## Sources present

| source | jurisdiction | data | licence |
|---|---|---|---|
| bankofengland | n/a | n/a | n/a |
| US Treasury | US | daily yield curve | public domain |
| US Treasury Fiscal | US | average interest rates | public domain |
| ECB | EU | official euro reference rates | ECB terms |
| FRED (St. Louis Fed) | US | rates + macro series | CC-BY-4.0 |
| SEC municipal advisers | US | registered municipal advisor registrations | US public record |
| NY Fed | US | reference rates (EFFR/OBFR/SOFR) + SOMA holdings | public |
| progress.png | n/a | n/a | n/a |
| US Treasury | US | daily yield curve | public domain |

## What you can do with it

* Build discount curves
* Track issuance and auction demand
* Monitor federal interest cost

## For engineers

Data is stored as **tar shards** (the hub caps a directory at 10,000 files and these tiers
run to millions). Members keep their original names and relative paths.

```python
import tarfile
with tarfile.open("0000.tar") as tf:
    print(tf.getnames()[:5])
    tf.extractall("out/")
```

| shard | size |
|---|---:|
| `README.md` | 6.8 KB |
| `bankofengland/0000.tar` | 133.1 KB |
| `data/treasury/0000.tar` | 675.8 KB |
| `data/treasury_fiscal/0000.tar` | 174.1 KB |
| `ecb/flows/0000.tar` | 3.38 MB |
| `fred/rates/0000.tar` | 4.63 MB |

_Showing 6 of 21 shards._

Every shard records its **sha256** in the pipeline ledgers; shards are append-only, so a
resumed run re-uploads only what changed. A shard with a failed member is never marked
complete, so missed files are retried rather than dropped.
