NEW YORK/LONDON, April 19 (Reuters) - Global stocks and commodity prices fell on Monday after Friday's fraud charges against Goldman Sachs rattled markets around the world and sent investors scurrying to such safe havens as the U.S. dollar.
Concerns about a delay in planned talks in Greece with the European Union and International Monetary Fund over a possible 45 billion euro ($62.91 billion) bailout added to widespread risk aversion.
Investors are keen to see Athens activate the deal but the ash cloud caused by the Icelandic volcano disrupted travel in Europe and helped delay Greek debt talks.
Copper fell to three-week lows and crude oil slipped to around $81 a barrel on dampened risk appetite in the wake of the charges against Goldman -- a leading commodities player -- and as European flying restrictions curbed jet fuel use. [

]"This is clearly a risk-averse market," said Omer Esiner, senior market analyst at Travelex Global Business Payments in Washington. "The main triggers are still the SEC's bombshell on Goldman Sachs and the continued uncertainty about the Greek debt situation, specifically as to how any aid package would be applied or whether Germany would veto the package."

"The Goldman news is an isolated episode. It's not a game changer," said Steve Goldman, market strategist at Weeden & Co. in Greenwich, Connecticut.
"It's not going to change the backdrop of strong growth in the economy, it's not going to change lending practices, it's not going to change balance sheets," he said.
