Crude oil options volatility rose as futures retreated on talks by European finance ministers over aid to Greece.
Implied volatility for at-the-money options expiring in January, a measure of expected price swings in futures and a gauge of options prices, was 29.88 percent on the New York Mercantile Exchange as of 3:10 p.m., up from 29.54 percent on Nov. 9.
January-delivery crude oil declined 48 cents, or 0.6 percent, to settle at $86.07 a barrel on the Nymex.
“There is ongoing concern about Europe,” said Phil Flynn, senior market analyst at Price Futures Group in Chicago.
The most active options in electronic trading today were January $125 calls, which rose 1 cent to 4 cents a barrel on volume of 4,899 lots at 3:14 p.m. December $85 puts were the second-most active, with 3,127 lots exchanged as they declined 20 cents to 32 cents.
Bets that prices would rise, or calls, accounted for 56 percent of the 50,915 lots traded.
The exchange distributes real-time data for electronic trading and releases information the next business day on open- outcry volume, where the bulk of options activity occurs.
In the previous session, puts made up 51 percent of the 134,264 contracts traded.
