The rapid spread of COVID-19 has led to unprecedented supply chain disruptions worldwide, as well as significant commodity price volatility. The pandemic first brought China, and now the US, to a grinding halt. Yet backward looking government indicators of economic activity remain woefully inadequate for real time analysis, particularly when the situation changes so dramatically every day. For example, our China agricultural price index anticipates China’s official food CPI by two months. Gro’s agricultural price indices were specifically designed to solve this critical market deficiency. Each index is built on the Gro data platform, which contains hundreds of thousands of unique price series at the national, regional, and local levels (e.g., cities, processing facilities, grain elevators, and ports). We aggregate this local price data for each country, using a basket that represents the food consumption expenditures within the economy.
