All eyes down for Bernanke’s speech on Friday , but there’s a growing element of economists who don’t see a repeat of August 2010

‘Having established a reputation for ‘shock and awe’, economists say that the ammunition the Fed has left to help the economy is running dry. The most likely option at September’s meeting is to tell investors, consumers and companies that interest rates will be held at very low levels for even longer than the 2014 deadline it is already committed to. It may be helpful at the margin in encouraging investment but its effect will be limited.’
