DP20451 Geoeconomic Fragmentation and Commodity Markets
This paper studies the economic impact of commodity trade fragmentation. Using a novel production and trade dataset of 48 key commodities, we develop a partial equilibrium framework to identify the most vulnerable commodities to trade disruptions and assess the ensuing economic risks. Trade fragmentation can cause large price changes for many commodities, with minerals critical for the clean energy transition and selected agricultural commodities being the most vulnerable. The economic relevance of commodity trade fragmentation, measured by changes in consumer and producer surplus, varies across countries. However, offsetting effects across commodity exporting and importing countries, imply modest global surplus losses.
