Oil options volatility was little changed after underlying futures fell for the first time in three days as U.S. inventories rose last week.
Implied volatility for at-the-money options expiring in June, a measure of expected price swings in futures and a gauge of options prices, was 25.53 as of 3:25 p.m. on the New York Mercantile Exchange, versus 25.63 yesterday.
“Yesterday, volatility was down a little because of the rally,” said Fred Rigolini, vice president of Paramount Options Inc. in New York. “Today, crude is down, but it hasn’t been able to break out of the range.”
Crude oil for May delivery fell $1.53, or 1.5 percent, to settle at $102.67 a barrel on the New York Mercantile Exchange, after settling at the highest level since April 2 yesterday. Crude since April 4 has traded in a range of $100.68 to $105.07.
Crude for June delivery lost $1.52 to $103.12. May futures expire April 20.
