Oil options volatility was little- changed as the underlying futures rose amid speculation that euro-area leaders will do more to fight the debt crisis.
Implied volatility for at-the-money options expiring in January, a measure of expected swings in futures and a gauge of options prices, advanced to 40.8 at 2 p.m. in New York from 40.6 on Nov. 23.
“We look for the euro zone to be the primary driver of oil pricing through the balance of this month and well into the next,” Jim Ritterbusch, president of Ritterbusch & Associates, a Galena, Illinois-based consulting company, said in a report.
