Oil jumped the most in more than six years, caught up in a relief rally that swept the globe as the U.S. economy grew more than predicted.
West Texas Intermediate futures rose 10 percent, the biggest gain since March 2009. U.S. gross domestic product grew at a 3.7 percent annualized rate in the second quarter, exceeding all estimates of economists surveyed by Bloomberg. The Standard & Poor’s 500 Index headed for its biggest two-day gain since 2009 as Chinese shares snapped a five-day losing streak.
Prices extended gains after Royal Dutch Shell Plc issued a force majeure on Bonny Light exports from Nigeria as it worked to repair two crude pipelines shut because of thefts and a leak.
Oil had slumped below $40 this week as concern over slowing demand in China fueled volatility in global markets. Prices are down about 31 percent from this year’s closing peak in June on speculation that a world supply glut will be prolonged. OPEC members are sustaining output while U.S. stockpiles remain more than 90 million barrels above the five-year seasonal average.
“We’re getting whiplash moves,” Matt Sallee, who helps manage $17.7 billion in oil-related assets at Tortoise Capital Advisors in Leawood, Kansas, said by phone. “The shorts are skittish and whenever there’s any positive data they cover very quickly.”
