Implied volatility for at-the-money options expiring in January, a measure of expected price swings in futures and a gauge of options prices, was 29.96 percent on the New York Mercantile Exchange as of 2:35 p.m., down from 30.5 percent yesterday.
“You’re seeing a little slippage in volatility because of the higher price,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
January-delivery crude oil rose 91 cents, or 1.1 percent, to settle at $86.75 a barrel on the Nymex.
Prices rose after Israeli jets struck the Gaza Strip today, killing the leader of Hamas’s military wing, as the army pledged the use of ground troops if required to end attacks on Israel’s citizens.
