Oil Options Volatility Rises as Futures Gain on Stimulus Bets

Crude oil options volatility increased as the underlying futures rose the most in four weeks.

West Texas Intermediate crude for July delivery gained $1.48, or 1.6 percent, to settle at $93.45 a barrel on the Nymex. The Dollar Index, a weighing of the U.S. greenback against a basket of major currencies, fell 0.9 percent, fueling bets that the Federal Reserve will maintain its pace of stimulus.

The most-active options in electronic trading today were July $87 puts, which declined 20 cents to 20 cents a barrel on volume of 3,072 contracts on the Nymex. July $100 calls were the second-most active, rising 4 cents to 9 cents on 2,995 lots.

Puts accounted for 51 percent of electronic trading volume today and 56 percent of the prior trading day’s volume of 93,143 contracts.
