China’s manufacturing grew less than economists estimated in April, a report Thursday showed. WTI surged to a five-month high on March 3 on tension between Russia and Ukraine.
“It’s hard to argue for $100 WTI with oil supplies about as high as they’ve ever been,” said Michael Lynch, the president of Strategic Energy & Economic Research in Winchester, Mass. “Although there’s increasing tension in Eastern Europe, the oil market is moving on the supply-demand balance at the moment. WTI should soon be trading in the mid-$90s.”

“It’s hard to be bullish with oil supplies near records,” said Phil Flynn, senior market analyst at the Price Futures Group in Chicago. “Barring a disruption of supply or a major ratcheting up of tension in Ukraine, we could see a dramatic drop in oil prices. Crude, gasoline and diesel have probably peaked for a long time.”
