Officials at the US Federal Reserve are working to calm the market sentiment after indications that the US central authority might start rolling back its stimulus package too soon.

The officials are aiming to change the US monetary policy goals in order to keep the interest rates low for longer for calming markets and keep borrowing costs low. There are concerns in the government circles that the investors might push bond yields higher when the central bank introduces cuts in its bond-buying programme.

The Federal Reserve officials are trying to calm the situation by convincing investors that the Federal Reserve will not suddenly withdraw stimulus package that has helped the US economy survive the financial crisis by keeping the borrowing costs low. The reserve will continue to provide stimulus to support the recovery of the economy but has indicated that it will begin a gradual roll back.

Financial markets had recently fallen on concerns that the Federal Reserve might start rolling back its $85 billion a month bond-buying programme within this year. The remarks by Federal Reserve Chairman Ben Bernanke that highly accommodative monetary policy will be needed to boost the economy in the near future, convinced investors to reconsider the risk position of an early roll back of the Fed's programme.
