A flurry of dealmaking by companies on both sides of the Atlantic has given the year the busiest start for mergers and acquisitions activity for a decade, firming up expectations of a bounce back in volumes as the economy recovers. With deals worth $34bn (£22bn) announced globally on Sunday and Monday, deal volumes so far this year have topped $83bn, up from $67bn last year, report the Financial Times. That puts 2011 ahead of the boom years, says Dealogic, with deal volumes higher than in any year-to-date period since 2000.
