Crude oil options volatility rose as the underlying futures fell after U.S. industrial production unexpectedly shrank and euro-area exports declined the most in five months.
Implied volatility for at-the-money options expiring in April, a measure of expected price swings in futures and a gauge of options prices, rose to 19.44 percent on the New York Mercantile Exchange from 16.83 percent yesterday.
West Texas Intermediate crude for April delivery fell $1.49, or 1.5 percent, to settle at $96.41 a barrel on the Nymex. Futures pared the week’s gain as January factory output slipped while euro-area exports dropped in December.
