Beschreibung

Russia, the world’s largest wheat exporter since 2017/18, has repeatedly restricted its grain exports with taxes, quotas or bans. Such policy intervention can induce uncertainty to futures, as well as spot markets, jeopardizing global food security. Building on high-frequency, transaction-specific wheat futures price data from the Chicago Board of Trade (July 2013 through October 2020), we measure contemporaneous, pre- and post-announcement volatility effects of Russian grain trade policy announcements. Computing various realized volatility measures from five-minute intra-day returns, our results suggest increased volatility on days leading up to newswire reports on Russian grain export policy. For comparison, we find similar pre-announcement effects on days preceding pre-scheduled crop reports released by the US Department of Agriculture, corresponding to publications of analyst poll results. We confirm that realized volatility measures are well-equipped to analyze punctual volatility events compared to conditional GARCH volatility, which can only depict longer-lasting volatility effects.
