NEW YORK -- U.S. stocks fell hard Monday as a political stalemate in Greece rattled financial markets worldwide.
The Dow Jones industrial average dropped 130 points to 12,690 a half-hour after the opening bell. That's a loss of 1 percent.
Oil dropped below $95 per barrel, and the euro sank against the dollar. Treasury prices jumped as traders shifted money into the safest bonds. The yield on the 10-year note fell to 1.77 percent, the lowest level this year.
Political parties in Athens resumed power-sharing talks Monday as negotiations to create a government drag into a second week. The uncertainty has raised concerns that Greece could miss a debt payment and drop out of the euro currency. The worry is that if Greece leaves the currency union, bond traders may turn on other troubled countries in Europe and demand steeper borrowing rates on the government bond market.
In other trading, the Standard & Poor's 500 index dropped 13 points to 1,340. The Nasdaq composite fell 24 points to 2,909.
