PEPIndex (PEPI) is a daily composite index that quantifies U.S. trade policy pressure from public government sources. It tracks the gap between announced tariff policy and actual implementation, combining Federal Register notices, USTR actions, USITC applied rates, BLS price data, and FRED economic indicators into a single scored signal.

Latest reading (as of 2026-09-22): composite index 17.8 · 30-day trend -14.1 · 90-day trend -11.9 · 55 active events, 24 resolved in 30 days. Live JSON →
The index scores each policy event on six behavioural dimensions — reversal magnitude, timeline slippage, rhetorical dilution, scope reduction, framing shift, and repetition pattern — blended into a weighted composite. A score of 0 indicates full implementation; 100 indicates complete reversal or abandonment. The daily index is a recency-weighted roll-up of scored events over a rolling window.
All sources are public. Statements and documents are classified by a language model with human review; non-trade outcomes are reconciled against independent reporting, which is weighted above self-reported posts, and every outcome records its evidence source. No commercial aggregators, licensed market terminals, or third-party scrapers are used. See the full data-source taxonomy.
