LONDON, April 19 (Reuters) - Worries about the impact of fraud charges against Goldman Sachs <GS.N> rattled stock markets on Monday, sending investors in search of less speculative currencies, which boosted government bonds.
Wall Street also look set to open lower.
The Goldman fears combined, in Europe, with concerns over the economic impact of disruption of commerce due to the cloud of Icelandic volcanic ash.
It has already cost the airline industry hundreds of millions of dollars, left millions of passengers stranded, and hit importers and exporters.
The travel disruption is also delaying talks on Greek debt, pressuring its sovereign debt and sending the spread against German bunds to a lifetime high.
The U.S. Securities and Exchange Commission on Friday charged Goldman with fraud over its handling of a debt product tied to subprime mortgages. [
]The result was a wave of risk aversion across financial markets. Some analysts also have been suggesting that equities in particular are due for a pause after world stocks hit a new year high last week.
"The sell-off is not entirely surprising considering the strong performance for risky assets in March and the first weeks of April," SEB said in a note.
MSCI's all-country world index <.MIWD00000PUS> was down nearly 1 percent, with its more volatile emerging market component <.MSCIEF> off more than 2 percent.
The latter was on track for its biggest one day fall since Feb. 5.
In Europe, where the airline industry has ground to a halt as a result of the volcanic ash cloud from Iceland, the pan-European FTSEurofirst 300 <
> was down 1 percent.Earlier, in Japan, the Nikkei <
> closed down 1.74 percent. Market players said the Nikkei was ripe for profit-taking after surging to an 18-month peak earlier this month, in a rally that spurred worries the market may have risen too far, too fast.
YEN RISES
The low-yielding yen rose broadly in a move that reflect concerns among investors.
"People are buying yen on the back of increasing risk aversion. It's risk-off on the Goldman news and worries over this week's EU/IMF meeting on Greece. That's also hitting the euro," said Michael Hewson, analyst at CMC markets.
Talks between the EU and IMF, expected to start on Monday, have been delayed to later in the week due to the ash cloud. [
]The euro was trading down against both the dollar and the yen. Against the yen, it was down 0.9 percent at 123.40 yen <EURJPY=R> after shedding around 1.5 percent on Friday after the Goldman news. Against the dollar, it was down half a percent to $1.3425 <EUR=>.
On fixed income markets, euro zone government bond yields fell.
The premium investors demand to buy Greek government bonds rather than German benchmarks rose to record levels as uncertainty over the implementation of an aid package for debt-stricken Athens unsettled investors. (Additional reporting by Neal Armstrong, editing by Mike Peacock and Neil Stempleman)
