NEW YORK Global stocks slid on Monday on worries Greece could leave the euro zone, while oil prices fell after a move by economic powerhouse China to boost lending sparked fears its economy was weaker than thought.
Data pointing to a deeper European recession, along with growing unease over the Greek debt crisis, pushed shares down nearly 2 percent to a 4-1/2-month closing low in Europe, while the euro hit a near four-month low against the dollar.
Stocks on Wall Street fell about 1 percent to a three-month low and government debt gained, pushing German and British yields to record lows, after coalition talks in Greece on Sunday faltered and increased the chance of mid-June election.

"It is all about the safe-haven trade - the flight to safety and the rush from fear," said David Dietze, investment strategist at Point View Wealth Management in Summit, New Jersey.
"We are looking at the highest risk since the euro sovereign debt crisis started, that one of their member countries, Greece, is going to break away from the euro," Dietze said. "Since a member has never left, the exact repercussions for the euro economy or even the euro currency are just unknown."
The benchmark 10-year U.S. Treasury note was up 18/32 in price to yield 1.78 percent.
German 10-year yields plumbed a record low of 1.434 percent, and yields on 10-year British gilts fell to a record low of 1.86 percent.

Compounding the picture for investors was data that showed output at factories in the euro zone unexpectedly fell in March, the latest in a series of disappointing numbers signaling the bloc's recession may not be as mild as policymakers hope.
Industrial production in the 17 countries sharing the euro fell 0.3 percent from February, the EU's Eurostat statistics office said. Economists polled by Reuters had expected a 0.4 percent increase in March.
Signs of a struggling Chinese economy also chilled investor sentiment. China, the world's second-biggest economy, cut bank reserve requirements on Saturday to free up an estimated 400 billion yuan for lending in a bid to avert a sudden slowdown.
