Assessing tight global wheat stocks and their role in price volatility

The Russia-Ukraine war has caused significant price volatility in agricultural markets over the past year — for wheat, in particular, price levels and price volatility reached the highest levels since the 2007/08 marketing year. Both have fallen back to pre-war levels over the past six months, but volatility remains high relative to historical levels (Figure 1), indicating that significant market uncertainty remains, creating ongoing vulnerability for global food security. Before 2022, volatility (measured by the implied volatility in the wheat futures market) spiked and remained high three times since 2006 — in 2007/08 and then again in 2010/11 and 2012/13 (as indicated in the gray bands in the figure). Markets then remained relatively quiet until the recent spike following Russia’s invasion of Ukraine in February 2022. High volatility persists due to market uncertainty over the war and the relative tightness in stock levels, which provide little cushion against unforeseen production shortfalls.Non-PRIFPRI4; Food Security PortalMarkets, Trade, and Institutions (MTI); Food and Nutrition Polic
