Dec. 20 (Bloomberg) -- Crude options volatility slipped to while futures rose as better-than-projected economic growth in the U.S. countered concern that American budget negotiations will fail.
Implied volatility for at-the-money options expiring in February, a measure of expected price swings in futures and a gauge of options prices, settled at 23.62 percent on the New York Mercantile Exchange, down from 24.03 percent yesterday.
February-delivery crude oil advanced 15 cents to settle at $90.13 a barrel on the Nymex, the fourth consecutive increase.
Futures reached a two-month high after the Commerce Department said U.S. gross domestic product grew at a 3.1 percent annual rate in the third quarter, greater than the highest forecast in a Bloomberg survey. Oil fell as much as 0.8 percent in intraday trading on speculation that efforts to avert the so-called fiscal cliff of tax gains and spending cuts are deteriorating.
The most active options in electronic trading today were February $85 puts, which fell 8 cents to 78 cents a barrel on volume of 1,067 contracts at 5:53 p.m. February $95 calls were the second-most active, with 980 lots exchanged as they declined 2 cents to 63 cents a barrel.
Bets that prices would fall, or puts, accounted for 60 percent of electronic trading volume.
