Dec. 2 (Bloomberg) --Brent crude put options rose as the international benchmark’s premium over West Texas Intermediate crude widened.
Implied volatility for puts protecting against a 10 percent decline in February Brent futures was 23.13 percent at 2:30 p.m. on the ICE Futures Europe exchange, up from 22.69 percent on Nov. 29. Calls protecting against a 10 percent gain slipped to 16.95 percent from 17.87 percent.
Brent for February settlement gained $1.72, or 1.6 percent, to $111.05 a barrel. The February contract’s premium to WTI increased 63 cents to $16.95.
“Because the Brent-WTI spread is extended so much, people playing that spread might want to buy some options,” said Phil Flynn, senior market analyst at Price Futures Group in Chicago. “If you’re long Brent, you buy puts in case there’s a correction.”
At-the-money volatility for February Brent options, a measure of expected futures swings and a key gauge of value, was 18.03 percent, down from 18.2 percent in the prior session.
The three most-active Brent options today were puts, which accounted for 65 percent of the volume. March $90 puts slipped 21 cents to 20 cents a barrel and the March $100 puts dropped $1 to 84 cents. Each traded 4,000 lots. The seven options with the highest open interest as of Nov. 29 were puts.
Implied volatility for at-the-money February WTI options was 18.82 percent, down from 19.04 percent on Nov. 29.
