Crude-oil options volatility slipped as underlying futures surged the most in 16 months after a European accord relieved concern that banks would fail and the region would sink further into debt.
Implied volatility for at-the-money options expiring in August, a measure of expected price swings in futures and a gauge of options prices, was 30.97 percent at 1:25 p.m. on the New York Mercantile Exchange, down from 32 percent yesterday.
“You have the higher price, volatility is coming off and we’re back up in the range we were before,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
Crude oil for August delivery rose $6.15, or 7.9 percent, to $83.84 a barrel at 1:28 p.m. on the Nymex.
Leaders of the 17 euro countries dropped requirements that taxpayers get preferred creditor status on aid to Spain’s banks and opened the way to recapitalize lenders directly. The region’s debt crisis has erased more than $4.9 trillion from global equity values this quarter amid concern Europe’s sovereign debt crisis would slow the global recovery.
Rigolini said traders were buying August $70 puts and August $90 calls and August and December straddles, where they bought a put and a call at the same price, betting on a large movement in either direction.
“You’re long a call and a put because you believe things are not going to be at this price very long and will either go a lot higher or a lot lower,” Rigolini said.
The most active oil options in electronic trading today were August $70 puts, which fell 27 cents to 5 cents a barrel at 1:30 p.m. with 4,963 lots trading. August $90 calls were the second-most active options, with 3,802 lots changing hands as they rose 40 cents to 46 cents.
Calls accounted for 60 percent of electronic trading volume. One contract covers 1,000 barrels of crude.
