NEW YORK (Reuters) - Oil prices surged 10 percent on Friday, one of the biggest daily rallies ever, as bearish traders who had taken out record short positions scrambled to close them, betting the market's long rout may finally be over.
The onset of a massive snowstorm on the U.S. East Coast sent U.S. heating oil HOc1 up more than 10 percent, helping fuel a 15 percent gain in crude prices over two days that has reversed nearly half of the relentless, fund-driven selloff that had pushed crude below $30 a barrel for the first time in 12 years.
"I think panic took over common sense and now we're starting to get a grip on reality," said Phil Flynn, analyst at Price Futures Group in Chicago.
A large driver of the rebound in prices over the last two days has been short covering, buying back barrels sold previously at a higher price, as investors take advantage of the lowest prices since 2003. Short positions in the U.S. oil futures and options markets had doubled in three months to record highs of more than 200 million barrels in the week to Jan. 12.
Data late on Friday showed that some bearish traders had begun taking profits even before the rebound, with short positions falling in the week to Jan. 19.
"Given the volatility we've seen in the oil price, even intraday, swings of 3 to 4 percent, if you are going to see a rebound, this is the kind of rebound you'd expect," CMC Markets analyst Jasper Lawler said.
Brent LCOc1 rose $2.93, or 10 percent, to settle at $32.18 a barrel. It was the biggest daily rise since a fierce short-covering rally in late August, when prices had just tested post-financial crisis lows around $42 a barrel.
At that time, Brent gained more than 25 percent in three days, the biggest three-day rally since the run-up to the first Gulf War in 1990. Some suggested there could be more gains next week as more shorts rush for the exit.
"Markets seldom repeat themselves with precision, but we see potential for a variation on that theme now," said Tim Evans, energy futures specialist at Citi Futures.
U.S. crude CLc1 rose $2.66 or 9 percent to settle at $32.19 per barrel.
The latest rally is somewhat less impressive on an absolute basis than on a percentage basis. Brent has gained $4 a barrel in two days, a more common occurrence when oil was over $100 a barrel in the years prior to 2014.
Freezing conditions and snowstorms have gripped parts of Europe and the United States, threatening to cripple a broad swath of the U.S. Northeast, the world's largest heating oil market, with about two feet (61 cm) of snow.
In the longer run, however, the cold snap may not be quite the boon oil bulls were hoping for.
Most in the industry maintained that the overwhelming bearishness of investors and oversupply woes persist.
"The big, big themes globally have not changed, but these are short-term positive developments," said Richard Hastings, macro strategist at Seaport Global Securities.
