London open: Glencore leads fallers early on

- Spain a concern as Catalonia needs aid- Markets await Bernanke- Ex-div Glencore a heavy faller early onEx-div stocks and miners were weighing heavily on the FTSE 100 index in early trading on Wednesday morning with worries about Spain weighing on sentiment.It was revealed yesterday that the recession in Spain was deeper than first thought in the second quarter, with concerns intensifying after reports that the regional government of Catalonia would be requesting around €5bn from Spain's liquidity fund."Catalonia also seems stubborn on political conditions relating to the emergency funds, causing some anxiety for potential future lenders to Spain as a whole. This is pretty big news for the Eurozone as any seemed resistance to conditions relating to any emergency funds could cause a pretty big headache down the line," said trader Simon Furlong from Spreadex.Economists at FxPro said in an e-mailed note this morning that investors are now waiting for Ben Bernanke for a lift: "As the Chairman of the US Federal Reserve gets up to speak on Friday, his words will determine whether markets are imbued with hope or despair ahead of the next US monetary policy meeting in September."FTSE 100: Ex-div stocks, miners down early onEx-dividend stocks were providing a drag this morning, including heavyweights Croda International, Glencore, Legal & General and Xstrata.Nevertheless, Glencore and Xstrata were being pressured lower by reports that Xstrata shareholder Norges Bank Investment Management has raised its stake in the miner in the last few weeks.
