The world's proved oil reserves total 236 billion barrels (last comprehensive global assessment, 2020 vintage, Energy Institute / BP Statistical Review). Divided by current world production, that is a runway of roughly 7.6 years at today's extraction rate — the classic R/P ratio, a mechanical arithmetic rather than a prediction, since reserves grow with discovery, technology and price. The interactive map colors every holder; clicking a country charts its 40-year reserve history, and each country's runway joins the 2020 reserves to CURRENT EIA production.

Why an inflation site tracks reserves: they are the ceiling on the supply side of the oil balance, and a short world runway is the structural argument for a higher long-run oil price — which passes into pump prices, freight and the CPI energy component within weeks.
