The FTSE 100 swung between gains and losses on Wednesday morning as investors kept their eye on developments in the Eurozone. By midday, the blue chip index was slightly in the red, with some disappointing manufacturing data weighing on sentiment.GREECE, EUROZONE MANUFACTURING, US FEDThe decision to hold a referendum on Greece's latest bail-out took the markets by surprise yesterday with major benchmark indices across Europe registering losses of anywhere between 3% and 7%. Despite calls for prime minister George Papandreou to cancel the vote, the cabinet agreed to back the decision early Wednesday morning. The prime minister will meet with French president Nicolas Sarkozy and German Chancellor Angela Merkel in Cannes this afternoon ahead of tomorrow's G-20 summit. Sarkozy said that Papandreou's decision was a surprise for all of Europe and that the rescue plan was the only solution to the Greek debt problems However, attention has moved from the eastern end of the continent to the western end, with reports suggesting that the European Financial Stability Fund (EFSF) has postponed the issue of a €3bn bond to fund Ireland's bail-out, because of volatile market conditions. One of the lead managers of the issue said the bond is expected to be prices over the next two weeks. Meanwhile, a survey measuring conditions in the Eurozone manufacturing sector fell to its lowest level in 27 months in October, as the European economic slowdown continues. The Purchasing Manager's Index (PMI) for the manufacturing sector compiled by Markit Economics showed a reading of 47.1 last month, compared with estimates of 47.3 and September's reading of 48.5. One particularly worrying result was seen in Germany, with the PMI coming in at 49.1, from 50.3 the month before. This was the lowest reading for the nation since July 2009 and its first reading below the 50 mark in some 25 months. The German statistics bureau also revealed today that the jobless rate rose from 6.9% to 7%, the first increase in over two years.Also, the Federal Open Market Committee (FOMC), the policy making committee of the US central bank, is expected in many circles to announce a further loosening of monetary policy this afternoon after its two-day meeting.
