"Traders are now being forced to cover their shorts as the market is reassessing the Fed's level of participation following lackluster response to Operation Twist in September," says commodities trader John Netto of M3 Capital.
"This coupled with a lot of hedge funds positioned short ahead of the EU summit has exacerbated the buying."
Another factor: WTI oil futures are now in "backwardation"—meaning the front month price is higher than future months—for the first time since November 2008.
"This means means index investors (mainly in the USO ETF) whose returns have been compromised since late 2008 despite oil's rise from $30 to $90 a barrel, are finally making money on the 'roll yield,' as they sell the front month and buy later months," says Tradition Energy analyst Addison Armstrong.
And, traders say this renewed backwardation of WTI crude oil prices may be encouraging more buyers to come in.
The Great Unwind
Also, the front-month premium of Brent crude to WTI oil futures has decreased by about $8 since last Thursday. The spread is now under $20. WTI oil prices plummeted last week on the announcement that Brent crude would be added to the DJ UBS Commodities Index next year, exacerbating the Brent premium to WTI futures.
The compression of this spread today may be more due to short-covering as some institutions speculate that Libyan oil may return to the market sooner rather than later, Armstrong says.
