Worries about Cypriot finances increased after the European Union gave Cyprus until Monday to raise the billions of euros it needs to get an international bailout, or face the collapse of its financial system and likely exit from the euro bloc.
Investors fear a collapse of the banking system in Cyprus will tighten credit across Europe and become yet another hurdle in the region's bumpy road out of economic crisis.
The ultimatum to Cyprus intensified the risk level in markets and increased investors' uncertainty, according to Chad Morganlander, portfolio manager at Stifel, Nicolaus & Co in Florham Park, New Jersey.
"The uncertainty within Cyprus has investors cycling into the risk-off trade," Morganlander said.

A downward trend in jobless claims, an increase in factory activity and a rise in sales of existing homes pointed to growing momentum in the U.S. economy during the first quarter of the year. Initial claims for U.S. unemployment benefits inched higher in the latest week, but the four-week average of new claims - a measure of labor market trends - fell to its lowest level in five years.
But the weak data from Europe drove down oil and copper prices. The S&P basic materials sector index fell 1.2 percent, making it the biggest drag on the S&P 500.
