US Business-Cycle & Core-Inflation Intelligence (FRED, keyless)
Monthly US core-inflation intelligence panel, 1959-01 onward: the Personal Consumption Expenditures price index excluding food and energy (chain-type index, 2017=100, seasonally adjusted; FRED PCEPILFE), the Federal Reserve's preferred inflation gauge. Carries 1-month, 3-month-annualized and 12-month percent changes plus an above_target_flag marking months where 12-month core inflation sits at or above the FOMC's 2% objective. Upstream: U.S. Bureau of Economic Analysis, Personal Income and Outlays release, redistributed keyless via FRED fredgraph.csv (restores the level series purged from the API-key FRED connector on 2026-09-29). Method caveats: chain-type indexes reweight continuously, so index levels are not comparable across distant eras without the percent changes; BEA revises history with annual updates. One row per month x USA; in-window nulls fail loudly, never imputed. Who joins this: online shops join pricing and demand on year_month + country_code; subscription businesses test whether above-target inflation months lead involuntary churn; sales teams weight pipeline by inflation regime.
Inflation Signals (derived)
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).
Statistics Norway (StatBank)
CPI, CPI-AT (adjusted for tax changes) and CPI-ATE (adjusted for tax changes, excluding energy) by 14 goods and services main groups: index (2025=100), monthly change and 12-month rate, monthly from July 2000. Source: StatBank table 14704.
Sticky vs Flexible Inflation Signals (derived)
Monthly signals derived from the Atlanta Fed's sticky-price and flexible-price CPI series (redistributed by FRED, 1968 ->; both series are published as 12-month percent changes): 30-month annualized point-change volatility, 3-month point-change momentum, the 12-month percent change itself, 3-sigma anomaly flags vs a trailing 12-month baseline, naive-drift 1-month forecasts, a per-month cross-series volatility rank, the sticky-minus-flexible spread (pp — the underlying-inflation gauge) and a 10-year sticky-inflation z-score (the persistence-regime gauge). 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); underlying data: Federal Reserve Bank of Atlanta.
