The plight of U.S. automakers highlighted the increasing damage which the world's financial crisis is inflicting on the real economy.

"We have contracting economic growth, falling corporate profits, and increasing unemployment which is filtering through to every part of the economy," said Henk Potts, investment manager at Barclays Stockbrokers.

The MSCI world equity index <.MIWD00000PUS> fell 2.3 percent to 197.90, its lowest since May 2003, driven lower in Asia after data showing Japan's exports to Asia fell for the first time in six years.

Oil fell by more than $1 a barrel to 22-month lows at $52.49 , as the slumping global economy hit demand.

The two-year U.S. Treasury yield hit a record low of 1.06 percent on expectations of a 50 basis point U.S. rate cut to 0.50 percent next month.

Euro zone government bond futures rose more than half a point to their highest since March 2006 at 120.36 .

The dollar dropped 0.77 percent to 95.20 against the safe-haven yen , but edged up against the euro to $1.2504 .
