Oil prices rose on Thursday as strong German economic data and continued uncertainty about an agreement on Iran's nuclear program provided lift a day after crude futures tumbled 6 percent.
Both benchmarks dropped around $3.50 on Wednesday.
Brent crude jumped more than 2 percent earlier as European equities strengthened on German industrial output and trade data, and as Greece said it will pay a loan tranche to the International Monetary Fund.
Also supportive were comments from Iran suggesting Tehran will only sign a final nuclear accord with six world powers if all sanctions imposed over its disputed nuclear program are lifted on the same day.
"The German data provided some lift early because it comes even before the expected economic boost from central bank quantitative easing and any sign that an agreement with Iran isn't going to get done is bullish," said Phil Flynn, analyst at Price Futures Group in Chicago.
