- All eyes on Bernanke - Merkel asks Italy to delay bailout request- Redrow Chairman makes takeover approachThe Footsie had moved into positive territory by Friday lunchtime following three straight days in the red, though gains were only mild as investors showed caution ahead of a pivotal speech by Federal Reserve Chairman Ben Bernanke later this evening.The big question on everyone's lips - "will Bernanke hint at another imminent round of quantitative easing (QE3)?" - will be answered tonight as the Fed frontman takes the stage in his keynote speech during the meeting of central bankers at Jackson Hole, Wyoming. "Two years ago at the same symposium, Bernanke dropped hints of QE2 which the Fed then announced a couple of months later. Given the backing in the previous minutes for further stimulus in the US, any hints Bernanke drops are expected to give an indication of how the Fed will act in September," explains analyst Craig Erlam from Alpari. "Because of this, every word he speaks will be over analysed repeatedly. The likely effect of this won't be that we'll be any better informed on how the Fed will act. Instead, it's more likely to simply fill the headlines over the next couple of weeks," he said.In other news, following the meeting between German Chancellor Angela Merkel and Italian Prime Minister Mario Monti in Berlin yesterday, Merkel has requested that Italy delays its request for aid, according to Spanish newspaper El Mundo. The reason being due to heightened tensions with the Bundesbank who is opposed to the European Central Bank's proposal of buying sovereign debt to bring down bond yields.FTSE 100: Miners on the up after recent sell-offMining stocks were making gains this morning, rebounding after bearing the brunt of 'risk-off' trade over the past few days.
