US President George Bush attempted to reassure investors on Monday.
"We are in challenging times," Mr Bush said at a press conference.
But he added that the US authorities were "on top of the situation" but "when need be, will act decisively, in a way that continues to bring order to the financial markets."
"In the long run, our economy is going to be fine".
Under scrutiny after the steep fall in its share price, Lehman Brothers also attempted to reassure investors on Monday about its financial situation.
"Our liquidity position has been and continues to be very strong," Lehman Brothers said in a statement.
Asian stocks also fell, with Tokyo's Nikkei average closing 3.7% lower and Hong Kong's Hang Seng slumping 5.2%.
