Implied volatility for at-the-money options expiring in March, a measure of expected price swings in futures and a gauge of options prices, was 30.9 as of 4 p.m. in New York, up from 30 yesterday.
“There was a little bit more excitement in the market today, and as we come off again volatility is going to increase,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
Crude for April delivery fell $2.02, or 1.9 percent, to settle at $104.70 a barrel on the New York Mercantile Exchange. Preliminary volume in electronic trading for crude oil was 627,715 contracts as of 2:40 p.m. in New York, 1.4 percent above the three-month average through yesterday.
