US Cross-Asset Implied-Volatility Intelligence (FRED, keyless)
Daily US cross-asset implied-volatility panel, 2008-06-03 onward: the CBOE Volatility Index (VIX, S&P 500), Nasdaq-100 vol (VXN), gold vol (GVZ) and crude-oil vol (OVX) — 30-day expected volatility in index points (annualized %), redistributed keyless via FRED fredgraph.csv. Carries the VXN-VIX tech premium and OVX-VIX energy premium, VIX day-over-day changes, a trailing-63-day VIX z-score, a look-ahead-free trailing-252-day VIX percentile, documented calm/elevated/high regimes, a fear-spike flag (VIX up >= 20% in one day) and a 0-100 cross-asset volatility score (mean of the four trailing-252-day percentiles). One row per day all four indexes published; any null fails loudly. Who joins this: risk teams gate portfolio hedges on spike_flag and vol_regime; macro models condition on cross_asset_vol_score as the fear gauge; energy traders watch ovx_vix_spread for oil-specific stress; consumer-spending models use the VIX percentile as a confidence proxy.
US Natural-Gas Market Signals (derived)
Daily US natural-gas market signals from the EIA Henry Hub spot price (FRED DHHNGSP, 1997 ->, $/MMBtu): 90-day momentum, year-on-year change, 30-day change volatility, 3-sigma anomaly flags, naive-drift forecasts, price-spike day flags, an elevated-price ($5+) flag, a 5-year z-score, and a heating-season flag. The natural-gas companion to us-fuel-price-signals (pump prices) — gas moves on weather, storage, and LNG exports, with some of the sharpest spikes of any commodity. All rows normalized to country_code USA. Raw series: U.S. Energy Information Administration via FRED.
