Oil options volatility was little changed as underlying futures rose to the highest since May 15.
Implied volatility for at-the-money options expiring in September, a measure of expected price swings in futures and a gauge of options prices, was 29.06 percent at 3:20 p.m. on the New York Mercantile Exchange, down from 29.48 yesterday.
“Crude is starting to break out of the range and that’s going to be a little volatile for prices, so volatility came off the lows a little toward the end,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
Crude oil for September delivery rose $1.47, or 1.6 percent, to settle at $93.67 a barrel on the Nymex. Prices touched $94.42, the highest intraday level since May 17.
Futures climbed as the Standard & Poor’s 500 Index touched the highest level since May 1, led by commodity and industrial shares, on speculation that central banks will add stimulus measures to boost growth. Rebels in Syria said Prime Minister Riad Hijab defected in the highest-ranking departure since an uprising began last year.

Calls accounted for 51 percent of total electronic trading volume. One contract covers 1,000 barrels of crude.
