New York - Wall Street stocks tumbled on Monday ahead of the first debate in the tightening US presidential campaign, and as worries about Deutsche Bank hit US financial stocks.
US-traded shares of the embattled German banking giant slumped 7.1% on reports that Berlin has refused state aid to fortify its capital base. US banks also fell sharply.
Investors were also uneasy over the debate Monday night between Republican presidential nominee Donald Trump and Democrat Hillary Clinton, said Peter Cardillo, chief economist at First Standard Financial.
"The market is beginning to realize that it may not be an easy win for Clinton," Cardillo said. "Normally a Republican win would be positive for the stock market, but with Trump it may create a lot of uncertainties."
