Federal Reserve chairman Ben Bernanke has given his strongest signal yet that he will begin another round of quantative easing in the US, to try to acheive the economic "benefits" of the UK programme.
Speaking at the Federal Reserve Bank of Boston, Bernanke suggested the country should have an inflation target of around 2%. Currently it is 1.1%.
To reach this figure a new round of economic stimulus through asset purchases could be on the way, he said, citing success in the UK.
Bernanke said: "A means of providing additional monetary stimulus, if warranted, would be to expand the Federal Reserve's holdings of longer-term securities.
"Empirical evidence suggests our previous program of securities purchases was successful in bringing down longer-term interest rates and thereby supporting the economic recovery.
"A similar program conducted by the Bank of England also appears to have had benefits."
However, Bernanke stressed the challenges faced by the Federal Reserve when deciding on whether to go ahead with more quantitative easing.
He said with asset purchases, relative to conventional monetary policy, he is working with much less experience in judging the economic effects.
"Substantial further expansion of the balance sheet" could reduce public confidence in the Fed's ability to execute a smooth exit from its recessionary measures, he said.
