We evaluate differential effects of the trading activity of two classes of traders: hedgers and general investors, on the volatility of the NYMEX crude oil futures returns. It appears that the rebalancing activity of oil hedgers has a significant and positive effect on the oil futures volatility. On the other hand, non-commercial players (investors) who take positions in the crude oil futures as well as stocks and bonds do not affect the crude oil volatility significantly by rebalancing their positions.
