The United States will call on G20 countries to use all monetary and fiscal tools at their disposal in order to boost global demand, a senior U.S. Treasury official said on Monday, according to Reuters. "We will urge greater use of policy space, including fiscal space, to bolster global demand. That would lead to strengthened confidence and I would suspect reduce volatility," the Treasury official said in a preview call with reporters ahead of a G20 meeting later this week in Shanghai, China. G20 finance ministers, including U.S. Treasury Secretary Jack Lew, and central bank governors will meet on Feb. 26-27, with sagging global growth, divergent monetary policies and currency devaluations set to dominate the agenda.
