The FTSE 100 jumped higher from the off on reports that European leaders are drawing up a plan to increase the region's firepower against the crisis. The index jumped to 5,611 early on, an intraday level not seen in almost a month (intraday high of 5,616 hit on 9 November).The European Union is preparing a plan that would include the simultaneous running of two independent rescue funds along with larger financial support from the International Monetary Fund, according to a front page article published today in the Financial Times (FT). According to the newspaper, leaders are working on this three-pronged proposal in order "to create a much bigger financial 'bazooka' to present at this week's European Union summit." Official sources cited by the daily say that the proposal would allow the existing €440bn fund to continue running when a new €500bn fund comes into effect in mid-2012.
