US inflation signals (CPI/PCE YoY momentum, core gaps, anomalies, forecasts)
Signals derived from FRED's US inflation series: 30-period annualized volatility of monthly changes, 3-month momentum, year-over-year percent change (the headline inflation gauge), 3-sigma anomaly flags, naive-drift 1-month forecasts, a per-month cross-series volatility rank, plus the core-vs-headline CPI gap and the core-PCE-vs-headline spread. Covers CPIAUCSL (headline CPI, seasonally adjusted), CPILFESL (core CPI), PCEPILFE (core PCE price index — the Fed's preferred gauge) and PPIACO (producer prices, all commodities). All rows are normalized to country_code USA so they join cleanly with US macro data. Raw series: Federal Reserve Bank of St. Louis (FRED).
