The Monetary Policy–Commodities Nexus: A Survey
Journal of Economic Surveys, Volume 40, Issue 2, Page 1050-1082, April 2026.ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...
