Oil options volatility was little changed as futures fell when the dollar gained against the euro on concern that Europe’s debt crisis is worsening.
Implied volatility for at-the-money options expiring in September, a measure of expected price swings in futures and a gauge of options prices, was 30.15 percent at 3:20 p.m. on the New York Mercantile Exchange, down from 30.16 on July 27.
“It’s a lackluster trading environment, no real direction,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
Crude oil for September delivery dropped 35 cents to settle at $89.78 a barrel on the Nymex, the first decline in five days. The dollar rose 0.5 percent against the euro at 3:30 p.m. in New York, the first gain in four days. A stronger dollar reduces the investment appeal of commodities.
The most active options in electronic trading today were September $80 puts, which fell 4 cents to 18 cents a barrel at 3:32 p.m. with 2,014 lots trading. September $95 calls were the second-most active options, with 898 lots changing hands as they declined 21 cents to 63 cents a barrel.
Calls accounted for 52 percent of total electronic trading volume. One contract covers 1,000 barrels of crude.
The exchange distributes real-time data for electronic trading and releases information the next business day on floor trading, where the bulk of options trading occurs.
