Nov. 18 (Bloomberg) -- Oil options volatility rose as the underlying futures retreated on concern that the planned reversal of the Seaway pipeline won’t be enough to eliminate a glut of crude oil in the U.S. Midwest.
Implied volatility for at-the-money options expiring in January, a measure of expected swings in futures and a gauge of options prices, rose to 38.6 at 1 p.m. in New York, from 37.9 yesterday. Brent’s premium to West Texas Intermediate oil rose after narrowing to an eight-month low Nov. 16 following the announcement by Enbridge Inc. and Enterprise Products Partners LP that they will reverse the direction of the line.
“A bigger pipeline effect is expected when it actually starts influencing the physical market,” Thina Saltvedt, an analyst at Nordea Bank AB in Oslo, said in an e-mail.
