Fed's Yellen says weak fiscal support has slowed global recovery

US Federal Reserve Chair Janet Yellen on Friday called on politicians across the globe to get their fiscal houses in order during good times to prop up economies during times of turmoil.

In remarks to a symposium in Paris, Yellen blamed part of the slow global economic recovery on weak government support.

She took aim at both US political gridlock after the 2007-2009 financial crisis and the austere policies across Europe as the region struggles with persistently low inflation.

The crisis led major central banks to deploy unconventional tools to spur recovery. For its part, the Fed cut interest rates to zero and more than quadrupled its balance sheet to $4.4 trillion through three rounds of bond buying, eliciting howls of protest from some politicians who feared the monetary largesse would spark an unwanted inflation. It announced an end to its latest asset purchase programme just last week.
