Crude options volatility slid as oil rose after German investor confidence jumped to a seven-month high in December and OPEC members gathered in Vienna to discuss production levels.
Implied volatility for at-the-money options expiring in February, a measure of expected price swings in futures and a gauge of options prices, was 27.37 percent on the New York Mercantile Exchange as of 3:40 p.m. local time, down from 27.87 percent yesterday.
Crude for January delivery advanced 0.3 percent to $85.79 a barrel on the Nymex after five days of declines.
An index by the ZEW Center for European Economic Research of investor confidence in Germany rose more than expected on speculation the economy will gather momentum next year. The Organization of Petroleum Exporting Countries will probably leave its production quota unchanged when oil ministers meet tomorrow, a Bloomberg survey showed.
