Crude-oil options volatility fell as the underlying futures advanced for a second day.
Implied volatility for at-the-money options expiring in July, a measure of expected price swings in futures and a gauge of options prices, was 26.7 percent at 3 p.m. on the New York Mercantile Exchange, down from 26.9 percent yesterday.
“We held ahead of the weekend, but we’re just slightly down because we’re kind of in a tight range today,” said Fred Rigolini, vice president of Paramount Options Inc. in New York.
Floor trading is closed on May 28, the U.S. Memorial Day holiday.
Crude oil for July delivery rose 20 cents to settle at $90.86 a barrel on the Nymex, below $91 for the third straight day. Prices are down 17 percent since their year-to-date high settlement of $109.77 on Feb. 24.
Oil rose on reports that U.S. consumer confidence gained and that the United Nations’ atomic agency found evidence Iran boosted its output of enriched uranium, which could be used for a nuclear weapon.
