NEW YORK, April 19 (Reuters) - Global stocks and commodity prices slid on Monday after Friday's fraud charges against Goldman Sachs rattled markets around the world while lifting the U.S. dollar as investors sought safety.

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. Greek bond prices and bank shares both fell.

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 the Greek debt talks. For details see: [ID:nLDE63I1J1]

Copper fell to three-week lows and crude oil slipped about 2.7 percent to around $81 a barrel on heightened risk aversion in the wake of the charges against Goldman -- a leading commodities player -- and as European flying restrictions curbed jet fuel use. [ID:nSGE63I00Y] [ID:nLDE63I0SQ]

The restrictions on European flights, which have stranded passengers around the world and halted freight flights, also took a heavy toll on prices of shares of airliners.

Gold also fell on the Goldman news, although it recovered from two-week lows as some investors sought the metal as a haven. [ID:nLDE63I0TC]

Investors ignored news that a gauge of the U.S. economy's prospects rose to a record high in March, suggesting a steady recovery, the Conference Board, a private research group, said of its index of leading economic indicators.

Some investors said the fraud charges against Goldman, which the bank has called "completely unfounded," were isolated to the bank and did not affect the economic recovery. But the charges may give new life to efforts by the Obama administration and Democrats to reform financial regulation.

"This Goldman Sachs affair is certainly something that is keeping investors a bit wary because it could become a key for more stringent regulations," said Luc Van Hecka, chief economist at KBC Securities.

"This is clearly a risk-averse market," said Omer Esiner, senior market analyst at Travelex Global Business Payments in Washington.
