The United States said it would extend a reprieve that permits China’s Huawei Technologies to buy components from U.S. companies, signaling a slight softening of the trade conflict between the world’s two largest economies

A rally in equity markets around the world on growing expectations that global economies will take action against slowing growth also supported crude prices

China’s new lending reference rate was set slightly lower on Tuesday after the central bank announced interest rate reforms designed to reduce corporate borrowing costs, while Germany’s right-left coalition government said it would be prepared to ditch its balanced budget rule and take on new debt to counter a possible recession

“China’s announcement of key interest rate reforms over the weekend has driven expectations of an imminent reduction in corporate borrowing costs,” financial services firm Cantor Fitzgerald said in a note

Traders were also watching for signs of tension in the Middle East after the United States called the release of an Iranian tanker at the center of a confrontation between Iran and Washington unfortunate, warning Greece and Mediterranean ports against helping the vessel
