We examine the impact of international monetary policy and professionals' announcements on West Texas Intermediate crude oil futures. Our methodology features an event study and a case study.

The direction, magnitude and significance of impacts are assessed in terms of returns and volatility for both daily and weekly price, volume and open interest series.
