Base metals “are popping on policy news out of Europe indicating that the banking crisis might be taking a breather,” Scott Gardner, chief investment officer at Verdmont Capital, told Bloomberg. “The Chinese have also recently hinted at easing monetary policy, which would be a big boost for the industrial-commodity trade.”
