(Bloomberg) -- Oil rose as investors assessed a patchwork recovery in energy demand, with signs of a rebound from the pandemic in some countries such as the U.S. mixed with setbacks in parts of Asia where the virus is still rampant.West Texas Intermediate gained 0.6% on Friday but remains on course for a weekly drop of around 2%, extending April’s pattern of alternating between weekly gains and losses as investors respond to the complex mosaic of signals. Among the latest were evidence of rising U.S. and U.K. gasoline demand, but also a virus wave in India that’s set a global record for daily infections.Oil remains more than 25% higher in 2021, aided by the roll-out of Covid-19 vaccines and vigilant supply management from the Organization of Petroleum Exporting Countries and its allies.

Southeast Asia’s biggest predominantly Muslim nations, Indonesia and Malaysia, are tightening movement restrictions to avert a possible surge. The month-long fasting period ends in mid-May.At present, OPEC+ is planning to add more than 2 million barrels of oil a day in stages over the three months to July, betting that overall demand will be robust enough to absorb the incremental supply. This week, Russia’s Deputy Prime Minister Alexander Novak said that the market looks balanced.In the Middle East, Yemen’s Houthi rebels said they attacked several targets including a Saudi Aramco facility in Jazan with explosive-laden drones. Saudi Arabia said it had intercepted and destroyed three drones aimed at the site, according to state-run television.
