WTI crude oil surged on Tuesday morning in Asia amid concerns that intensifying airstrikes in Russia and Ukraine could lead to supply disruptions. Ukrainian President Volodymyr Zelenskiy on Sunday reportedly vowed to retaliate against Russian drone strikes on power facilities in his country's north and south and ordered more attacks deep inside Russia. Besides, rising bets of a Federal Reserve (Fed) rate cut this month is also keeping the commodity supported. Investors brace for the American Petroleum Institute (API) weekly crude oil stock, which will be published later today. Crude oil futures are currently hovering around $65 per barrel mark at $64.91, up 1.4% on the day.
