Wall Street was lower on Tuesday as investors fretted over renewed uncertainties about the Federal Reserve's plan to raise interest rates this year.
International Monetary Fund Managing Director Christine Lagarde on Tuesday warned of increasing risks to global economic growth, unless there were stronger measures by policymakers.
Lagarde's comments come a week after Fed Chair Janet Yellen urged caution on rate hikes, citing a shaky global economy and low oil prices.
However, some Fed officials have supported an aggressive monetary policy, sparking concerns about the timing and the number of rate hikes this year.
While the Fed has projected two hikes in 2016, traders are pricing in only one, with an even chance that the central bank may pull the trigger in June, according to the CME Group's FedWatch program.
Nervous investors pushed up gold, a traditional safe-haven, by more than 1 percent.
"It's looking down just because you have a general environment of uncertainty," said Lisa Kopp, head of traditional investments at U.S. Bank Wealth Management in Minneapolis.
"The recovery is long in the tooth and there has been a lot of market moving news," she said, referring to comments by Lagarde and Fed policymakers, as well as volatility in oil.
