Dec. 17 (Bloomberg) -- Crude options volatility fell as the underlying futures rose on optimism that a U.S. budget agreement will be reached.
Implied volatility for at-the-money options expiring in February, a measure of expected price swings in futures and a gauge of options prices, was 25.69 percent on the New York Mercantile Exchange as of 3:45 p.m., down from 26 percent on Dec. 14.
February-delivery crude oil advanced 42 cents, or 0.5 percent, to settle at $87.67 a barrel on the Nymex.
Prices gained as House Speaker John Boehner proposed raising tax rates on household incomes above $1 million a year in exchange for containing entitlement program costs. Boehner previously opposed higher rates for any income level. President Barack Obama, who wants increased rates to start at $250,000, is considering a concession on Social Security cost-of-living advances, according to two people familiar with the talks.
