Dec. 6 (Bloomberg) -- Crude options volatility rose after oil fell when European Central Bank President Mario Draghi said the region’s slump will linger until the second half of 2013.
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 28.71 percent on the New York Mercantile Exchange as of 2:15 p.m., up from 26.73 yesterday.
January-delivery crude oil slid $1.62, or 1.8 percent, to $86.26 a barrel at 2:19 p.m. on the Nymex.
The ECB cut its growth and inflation forecasts and Draghi left the door open for further interest rate reductions, saying that ECB policy makers considered a rate cut today.
The most active options in electronic trading today were February $100 calls, which slipped 5 cents to 27 cents a barrel on volume of 6,576 lots at 2:20 p.m. January $85 puts were the second-most active, with 3,737 lots exchanged as they gained 40 cents to 97 cents.
