West Texas Intermediate crude options volatility rose above 14 percent for the first time in five days as West Texas Intermediate futures slipped below $100 a barrel.
Implied volatility for at-the-money February WTI options, a measure of expected futures movements and a key gauge of value, was 14.35 percent at 3:05 p.m. on the New York Mercantile Exchange, up from 13.72 on Dec. 27.
Volatility sank to 13.02 percent on Dec. 26, the lowest since at least 2006 amid low year-end volume and speculation prices won’t change significantly through the Christmas and New Year’s holidays.
“We were so low on Friday,” said Phil Flynn, senior market analyst at Price Futures Group in Chicago. “There was a little bit of a pullback when people realized they were scraping the bottom of the basement last week.”
February futures fell $1.03, or 1 percent, to $99.29 a barrel on the Nymex, after settling above $100 on Dec. 27 for the first time since Oct. 18. Prices have fluctuated between $96.21 and $100.75 since Dec. 4. Trading volume was 48 percent below 100-day average as of 3:09 p.m.
