LONDON (AFP) – London equities ended lower on Wednesday, with traders on tenterhooks before the outcome of the US Federal Reserve's latest monetary policy gathering, analysts said.
London's FTSE 100 index of leading shares lost 0.40 percent to close at 6,348.82 points.
Investors have been speculating about when the Fed will start tapering off its $85 billion-a-month bond-buying programme, known as quantitative easing and which is credited with helping push global equities to recent highs.
Global equities and currencies have been sent into turmoil in recent weeks on expectations that Fed chairman Ben Bernanke will start turning off QE.
Investors are therefore anxious to see what Bernanke will say Wednesday at his traditional post-meeting press conference.
"Chairman Bernanke's question-and-answer session is being viewed as a make or break moment for equity market momentum, though whether we will actually garner any clarity on the Fed's timeframe for tapering their stimulus programme remains to be seen," said analyst Matt Basi at traders CMC Markets.
