Stocks, Euro Sink on Concern Over Greek Rescue, Slowing Economy

U.S. stocks sank the most in two weeks, almost erasing the 2011 gain for the Standard & Poor’s 500 Index, and the euro slid the most in more than a month amid rising concern that Greece will default and evidence that the American economy is slowing. Treasuries rallied.

The S&P 500 fell 1.7 percent to a three-month low of 1,265.42 at 4 p.m. in New York, trimming its year-to-date gain to 0.6 percent, and the Stoxx Europe 600 Index closed down 1.1 percent. The euro lost 1.9 percent to $1.4166 and the cost of insuring Greek and Portuguese debt climbed to records. Oil sank to the lowest price since February as the S&P GSCI Index of commodities plunged 3.4 percent. The Dollar Index surged the most in 10 months, 10-year Treasury yields fell below 3 percent and two-year rates dropped the most since April.
