West Texas Intermediate crude options volatility rose, nearing the highest level since November, as futures fell to a five-week low amid rising supply.
Implied volatility for at-the-money February WTI options, a measure of expected futures movements and a key gauge of value, was 19.62 percent at 4:20 p.m. on the New York Mercantile Exchange, up from 18 percent on Jan. 3, according to data compiled by Bloomberg.
At-the-money volatility sank to 13.02 percent on Dec. 26, the lowest level since at least 2006, amid thin trading and speculation prices would remain range-bound through the Christmas and New Year’s holidays.
“While we believe oil-price risks are substantially skewed to the downside in 2014, further downside in volatility is likely limited,” analysts at Goldman Sachs Group Inc. including Jeffrey Currie said in a note today. “Should inventories begin to build in earnest in 2014, the relationship between volatility and inventories suggests that volatility should begin to rise as inventories build above the 5-year average.”
WTI for February delivery slid 53 cents, or 0.6 percent, to $93.43 a barrel on the New York Mercantile Exchange, the lowest settlement since Nov. 29. The five-day losing streak is the longest since September. The volume of all futures traded was 19 percent below the 100-day average at 2:57 p.m.
