Ben Bernanke, the chief of US Federal Reserve has warned the country's politicians, who are deliberating over the issue of fiscal cliff, over the risks posed to the fragile economic recovery in the US economy.

Bernanke said that the politicians could bring about a very good 2013 or face risks of a disaster. The U. S. central bank chief said on Tuesday that the uncertainty over the issue of fiscal cliff is putting pressure eon the economic growth as investors are hindered by prospects of $600-billion in tax increases and spending cuts.

President Barack Obama and congressional leaders have both said that they are committed to address the issue by reaching an agreement in time. The discussions on the matter are expected to go on in the month of December. Mr. Bernanke is urging the government and lawmakers to come to an agreement sooner to help boost economic growth and relieve pressure from the economy.

"Such uncertainties will only be increased by discord and delay. In contrast, co-operation and creativity to deliver fiscal clarity, in particular, a plan for resolving the nation's longer term budgetary issues without harming the recovery, could help make the new year a very good one for the American economy." Mr. Bernanke said.
