Crude oil options volatility sank to the lowest level since April 10 as the underlying futures jumped 1.2 percent.
Implied volatility for at-the-money options expiring in August, a measure of expected price swings in futures and a gauge of options prices, was 18.88 percent on the New York Mercantile Exchange as of 3:10 p.m., compared with 19.74 percent yesterday.
“We’ve had a little bit of a bull run here but we’re still in a big trading range,” said Phil Flynn, senior market analyst at Price Futures Group in Chicago. “If the market gets above $100 or below $87, the vols will go off the map.”
West Texas Intermediate crude for August delivery rose $1.15, or 1.2 percent, to settle at $98.07 a barrel on the Nymex. July futures gained $1.16 to $97.85.
The most-active options in electronic trading today were July $100 calls, which rose 1 cent to 5 cents a barrel on 4,912 lots at 3:47 p.m. on the Nymex. July $98 calls were the second-most active, rising 17 cents to 40 cents a barrel on volume of 3,410 contracts.
