Oil options volatility climbed after U.S. crude inventories dropped the most in seven months and on speculation central banks will take steps to support the economic recovery.
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 31.3 percent at 3:05 p.m. on the New York Mercantile Exchange, up from 31.1 yesterday.
Oil for September delivery increased 85 cents to settle at $88.91 a barrel on the Nymex after the Energy Department said U.S. crude inventories dropped 6.5 million barrels, or 1.7 percent, to 373.6 million. The Federal Reserve also said the economy has slowed and foreshadowed new steps to boost the weakening expansion.
“There’s a little bit of excitement anytime the Fed comes out and says anything about rates, even if they say it’s unchanged,” Fred Rigolini, vice president of Paramount Options Inc. in New York, said by telephone. “And there was kind of a surprising inventory draw here today, so that boosted volatility a little bit.”
The most active options in electronic trading today were September $80 puts, which fell 7 cents to 21 cents a barrel at 3:08 p.m. with 2,125 lots trading. September $85 puts were the second-most active options, with 2,010 lots changing hands as they declined 21 cents to 90 cents a barrel.
