Implied volatility for at-the-money options expiring in April, a measure of expected price swings in futures and a gauge of options prices, was 17.52 percent at 4 p.m. on the New York Mercantile Exchange, down from 19.81 yesterday.
“People aren’t as worried about a disruption in supply for oil because supplies are rising, and there’s expectation demand isn’t going to be so strong in the short term because we’re in the shoulder season between winter and summer,” said Phil Flynn, senior market analyst at Price Futures Group in Chicago.
