FTSE 100 above 6,600 for first time since 2007 The benchmark index climbed 21 points to 6,614 in early trade today, with moves by central banks around the world to boost stimulus measures in recent weeks contributing to a rally that has seen the FTSE 100 close higher every day this month. The last time it was at 6,600 was in October 2007. Some in the market, however, are sceptical about the strength of the rally, which has taken London's index of leading of shares back to levels last seen before the onset of the financial crisis. The FTSE 100 has now advanced about 12pc so far this year, having finished 2012 at 5,897.81. Central banks, seeking to support the global economy by cutting interest rates, are widely credited for pushing equities higher, as investors hunt for higher yields than those found in the bond markets. In April, the blue-chip index achieved its longest ever monthly winning streak by rising for 11 consecutive months. That beat the 10-month bull runs between 1986 and 1987, and 1996 and 1997.
