Asia's emerging economies should consider reining in monetary stimulus to curb the risks of asset bubbles and inflation as policy easing in developed nations, including Japan, spur capital inflows, the World Bank said.

Demand-boosting measures that helped sustain growth "may now be counterproductive," the lender said in its East Asia and Pacific Economic Update released Monday.

"As the global economy recovers, an emerging issue is the risk of overheating in some of the larger economies," it said in a release accompanying the report.
