U.S. West Texas Intermediate (WTI) crude futures rose $1, or 1.31%, to $76.19 after climbing 90 cents on Monday. Oil prices have been buoyed by U.S. plans announced last week to buy up to 3 million barrels of oil for the Strategic Petroleum Reserve after this year's record release of 180 million barrels. A weaker dollar has also supported prices, making oil cheaper for those holding other currencies. "The oil demand outlook will be key for how high crude prices can go," he said, adding that clarity on that could prove elusive given mixed signals on the reopening of China's economy. While China has been relaxing pandemic restrictions, a surge in COVID-19 cases has been bearish for oil markets because of uncertainty over the country's economic recovery, said CMC Markets analyst Tina Teng.
