US Treasury Yield Curve Tracker

Daily US Treasury par yield curve straight from treasury.gov: all tenors 1M–30Y, plus 2s10s / 3m10y / 5s30s spreads (bps) and inversion flags. Macro recession indicator. No API key.

---

Why this exists

The 2s10s spread (10Y yield minus 2Y yield) is the single most-watched recession indicator in finance. Every US recession since 1955 has been preceded by a 2s10s inversion.

The data is free and public — but it's published as a PDF and a clunky XML feed. This actor:

• Pulls the raw CSV from treasury.gov
• Computes 2s10s, 3m10y, 5s30s spreads (bps) automatically
• Flags inversion (negative spread) per row
• Configurable lookback (default 60 business days)
• Telegram alerts on inversion or spread threshold
