It said it would keep its range of interest rates near zero as long as the unemployment rate remains above 6.5%, near-term inflation stays below 2.5% and longer-term inflation expectations continue to be well anchored."While no doubt the Fed did deliver and lived up to expectations last night [...] markets still turned lower on a combination of profit taking as much of the news from the Fed has already been priced in and investors are now quickly starting to shift their focus to the budget stalemate in Washington where the US going over the 'fiscal cliff' in less than three weeks time is still a real possibility," said Markus Huber, the head of German HNW trading at ETX Capital.In the press conference following the Fed decision, Chairman Ben Bernanke said: "We cannot offset the full impact of the fiscal cliff ? it's just too big." Nevertheless, he did add that he thought the 'cliff' would be averted.FTSE 100: Wood Group hit by mixed updateEnergy services giant Wood Group has said that it expects to deliver good growth this year, with overall conditions in energy markets remaining "favourable".
