US Financial Stress Signals (derived)
Value-added financial-stress signals derived from FRED's free Federal Reserve financial-conditions indices: the Chicago Fed National Financial Conditions Index (weekly, 1971 -> present) and the St. Louis Fed Financial Stress Index (weekly, 1993 -> present). Each row carries change volatility, 13-week momentum, year-over-year level change, a trailing-1y stress z-score, a tight-financial-conditions regime flag, 3-sigma anomaly flags, naive-drift 1-month forecasts, a per-week cross-series volatility rank, and the NFCI-STLFSI stress spread. All computation is local pandas/numpy; no paid models or APIs.
US Consumer Credit Stress (FRED, keyless)
Quarterly US consumer credit-stress panel, 2005-Q1 onward: credit-card delinquency rate (SA, all commercial banks), credit-card plan APR, bank prime loan rate (quarterly mean of monthly), and the household debt-service ratio (required debt payments as % of disposable income), plus 4-quarter point changes, the card-APR-over-prime spread, and a documented 0-100 credit_stress_score (mean of full-panel min-max normalizations of delinquency, APR and debt-service; higher = more stressed) with s1..s4 stress tiers. Upstream: FRED keyless fredgraph.csv (DRCCLACBS, TERMCBCCALLNS, MPRIME, TDSP; Board of Governors of the Federal Reserve System). Panel start is set by TDSP's keyless coverage (2005-Q1). One row per quarter x USA; in-window nulls fail loudly, never imputed. Who joins this: subscription businesses join churn on year_quarter; online shops join demand on year_quarter + country_code.
USDA Food and Nutrition Service
Monthly US SNAP participation intelligence from the USDA Food and Nutrition Service monthly state participation and costs workbooks (keyless FNS program-data ZIP, FY2020 to present): participating persons, households and benefit costs for the 50 states, DC, Guam and the Virgin Islands, with MoM and YoY percent changes, each state's share of the national caseload, a documented 0-100 household-budget stress score with per-month ranks and tiers, rising / surge / 12-month-record-high flags, and month-level context (national average benefit per person). Joinable to orders/customers by ISO month + state for demand and churn modelling. FNS material is U.S. federal public domain (commercial reuse allowed); source: USDA Food and Nutrition Service.
