Crude oil options volatility rose as underlying futures fell the most since December after manufacturing in Europe and China slowed, indicating that fuel demand may drop.
Implied volatility for at-the-money options expiring in May, a measure of expected price swings in futures and a gauge of options prices, was 25.7 percent as of 1:28 p.m. in New York, up from 24.7 percent in the previous session. The measure has declined from 30.8 on March 6.
“Volatility is getting a little bit of a boost from the selloff,” said Fred Rigolini, vice president of Paramount Options Inc. in New York. “The market got a little tired with the rally and there were some bearish headlines.”
Crude for May delivery fell $2.48, or 2.3 percent, to $104.79 a barrel at 1:27 p.m. on the New York Mercantile Exchange, after touching $104.50. Futures have gained 6 percent this year. Since Feb. 21, the front-month crude oil contract has traded in a range of $103.78 to $110.55.
A preliminary measure of Chinese manufacturing was the lowest in four months, according to HSBC Holdings Plc and Markit Economics. The preliminary 48.1 reading is a decline from a final 49.6 in February.
A euro-area composite index based on a survey of purchasing managers in both industries fell to 48.7 from 49.3 in February, London-based Markit Economics said in an initial estimate today. A reading below 50 indicates contraction.
