Crude-oil options volatility rose to the highest level in two weeks and underlying futures fell as manufacturing contracted in the U.S. and China and euro-region unemployment rose to a record.
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 34.93 a barrel at 1:35 p.m. on the New York Mercantile Exchange, up from 30.74 percent on June 29.
Crude oil for August delivery dropped $1.81, or 2.1 percent, to $83.15 a barrel at 1:43 p.m. on the Nymex. Today’s loss followed a jump of $7.27 on June 29 as futures surged the most since March 2009.
“Volatility is up quite a bit,” said Fred Rigolini, vice president of Paramount Options Inc. in New York. “We saw end-of-the-quarter buying coming in on Friday and now, coming in after that, you’re seeing profit-taking based on some of the sluggish economic numbers.”
Futures declined today as the Institute for Supply Management’s factory index for the U.S. slid to 49.7 in June from 53.5 in May, the first contraction since July 2009. Chinese manufacturing indexes slipped to seven-month lows, while euro-area unemployment reached the highest level on record, rising to 11.1 percent in May from 11 percent in April, the European Union’s statistics office in Luxembourg said.
