Crude options volatility fell as futures were little changed, trading in a range of less than $4 a barrel the past five days.
Implied volatility for at-the-money options expiring in February, a measure of expected price swings in futures and a gauge of options prices, was 23.11 percent on the New York Mercantile Exchange as of 3:16 p.m., down from 24.41 percent yesterday.
“This is mostly due to the fact we’re range trading here at the higher price,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
February-delivery crude oil fell 20 cents to $92.92 a barrel on the Nymex after settling yesterday at the highest level since Sept. 18. Since Dec. 27, crude has traded in an intraday range from $90 to $93.87.
