-Greek forms new coalition government-MPC divided on more QE-Markets await the Fed decision later today News of the formation of a Greek coalition and hopes of further stimulus measures in the UK and the US gave stocks a lift on Wednesday afternoon.New Democracy leader Antonis Samaras was sworn in as Greece's new Prime Minister today. After winning Sunday's elections and meeting with other parties, Samarias met with President Karolos Papoulias at the presidential palace to announce the composition of the coalition government with the support of Pasok and Democratic Left. Pasok leader Evangelos Venizelos pointed to the upcoming European Summit as the place to debate the renegotiation of the Greek bailout conditions. Minutes from the latest Monetary Policy Committee (MPC) meeting in the UK were released this morning, showing that June's vote to leave the asset purchase programme unchanged was a contentious issue for policy makers, who were split five against four in maintaining the status quo. The previous month the MPC had voted seven-to-one in favour of leaving the QE pot at £325bn."Most members judged that some further economic stimulus was either warranted immediately or would probably become warranted in order to meet the inflation target," the minutes said. Meanwhile, investors await the outcome of the latest two-day meeting of the US Federal Open Market Committee (FOMC). Markets are hoping that members will vote on further easing measures in light of recent mixed economic data and Eurozone concerns. The latest Group of 20 (G20) meeting in Mexico over the last few days saw leaders promise to do what they can to support global growth without actually outlining any of the specific steps they plan to take. However, European officials promised to take "all necessary policy measures' to combat the current sovereign debt crisis".
