The UK's blue chip index has climbed to a five-year high above 6,400, surpassing the peak of 6,376 seen before the financial crisis.
The FTSE 100 ended yesterday's session at 6,379 points, higher than the previous five-year peak set in May 2008, and has continued to rise this morning, driven up by banks, tech companies and engineers.
By 10:06am the index had climbed above 6,400 to a high of 6,403.
Leading the index higher was beverage can giant Rexam, up 5.4% after a pleasing set of results which revealed its underlying profits had risen.
Other winners included Royal Bank of Scotland and tech company Sage Group, up 2.2% and 2.1% respectively.
The gains helped push the index to a new high despite disappointing news from non-life insurer RSA Insurance.
The group slashed its dividend amid a fall in operating profits, with shares tumbling 13% in reaction.
While the gains have taken the FTSE 100 to a new multi-year peak, it still has some way to go before it nears its all time high of 6,930 hit in December 1999.
