March 7 (Bloomberg) -- Crude options volatility slid to the lowest level since Feb. 13 as underlying futures rose the most since Feb. 11.
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.
West Texas Intermediate crude for April delivery rose $1.13, or 1.3 percent, to settle at $91.56 a barrel on the Nymex. Prices have declined 7.7 percent from a year-to-date high of $97.94 on Jan. 30.
U.S. crude supplies climbed 3.83 million barrels to 381.4 million last week, the highest level since June, according to data from the Energy Information Administration. Refinery utilization dropped to 82.2 percent of capacity, the least since March 16, 2012.

Calls accounted for 50 percent of electronic trading volume. In the previous session, calls made up 58 percent of the 134,242 contracts traded.
