Initial snapshot data

World Bank edition of 2 October 2026. Monthly averages transcribed from the Pink Sheet PDF editions (Oct. 2025 to Oct. 2026) by the Commodity Pulse project (MIT code). Spot-checked against the official June 2026 edition (Brent, copper, gold and wheat for May 2026: they match). The connector replaces them with the full official workbook (from 1960). As soon as the connector downloads the official workbook you'll see the full published history.

How to read this data

  • Each point is the monthly average published by the World Bank, in nominal dollars (not adjusted for inflation).
  • Volatility is the standard deviation of monthly returns over the last 36 months, annualised (× √12). It needs at least 12 consecutive months.
  • Maximum drawdown measures the largest fall from a previous peak over the last 5 years.
  • These are historical, descriptive metrics: they don't predict the future price. See the methodology.
