Crude oil broke through the $80 a barrel ceiling repeatedly during the week but kept falling back as hedge funds placed big bets on the Euro's decline.
The fiscal drama in Greece held global markets hostage much of the week as worries about the impact of the Greek crisis on the euro outweighed comments from Federal Reserve chairman Ben Bernanke about continued low interest rates in the U.S., pushing the euro down against the dollar and damping crude prices.
The euro recovered some ground on Friday amid new reports of European aid for Greece after falling to a nine-month low of $1.3440 on Thursday. Germany's state-owned bank KfW may take part in a planned Greek bond offering next week, according to market reports.
The Journal compared the situation to the hedge fund attack on the dollar in 2008. However, the trades are not expected to lead to a collapse of the currency as the attacks of George Soros on the British pound did in 1992, the paper said.
Positive U.S. economic data on Friday, including a revised fourth-quarter GDP annual growth rate of 5.9%, help crude oil futures claw back some of Thursday's losses and near the $80 threshold again. Nymex's benchmark West Texas Intermediate settled at $79.66 on Friday, after topping $80 earlier in the week.
Other analysts, too, looked for fundamental supply and demand considerations to reassert themselves amid the currency turmoil and lift crude oil futures into a higher trading range. Oil futures prices gained more than 9% in February but remained below January's highs.
