World stocks fell toward the previous week's 14-month low on Monday and the euro hit a 10-year low against the yen as doubts grew over how effective Europe's latest crisis-battling steps would be in containing the continent's sovereign debt problems.
European policymakers began working on new ways to stop fallout from Greece's near default, focusing on ways to beef up their existing 440-billion-euro rescue fund.
But deep differences remained over whether the European Central Bank should commit more of its massive resources to shoring up Europe's banks and help struggling euro zone member countries.
Concerns over the potential effect from Greece's possible default, especially on the banking sector, and worries over a U.S. economic slowdown have been weighing on world stocks, fanning safety-seeking flows into top-rated government bonds.

European stocks lost 0.8 percent while emerging stocks hit their weakest since September 2009.
The lurch lower in risk appetite can only reflect a growing fear that policymakers will be incapable of acting in time or with sufficient potency to turn things around, said Herv Goulletquer, analyst at Credit Agricole.
