TOKYO, Sept 5 (Reuters) - The yen surged to a 13-month high against the sliding euro on Friday as investors fled risky positions such as leveraged carry trades, spooked by a sharp fall in stock markets.
Escalating worries about global economic growth fed risk aversion among investors and hammered equities, with Japan's Nikkei share average <

Traders cited talk of more hedge funds going under after news earlier this week that Ospraie Management LLC, the world's biggest commodities hedge fund, was forced to close its flagship fund this week.
"This is not a flight to quality, it is simply a flight," said Alan Ruskin, chief international strategist at RBS Greenwich Capital. "Gold for example has failed to benefit, cash is king -- even the greenback, warts and all, or the yen, zero rates and all."
The sudden downgrade in expectations has forced a wide array of market players to unwind bets that favoured the euro, Australian dollar, commodities and emerging countries.
"The fall in equities is a global trend, but the declines in emerging countries, particularly Brazil and Russia, are more pronounced," Tohru Sasaki, chief forex strategist at JP Morgan Chase, said in a research note.
"Selling emerging currencies and buying back the yen is gathering momentum."

The euro dropped 0.3 percent to $1.4279 <EUR=> after sliding to a 10-month low of $1.4212 in frantic late U.S. trade.
Even the resurgent dollar succumbed against the yen, hitting a six-week low of 105.67 yen and down 0.4 percent on the day at 106.72 yen <JPY=>.
"Everyone it seems is closing out positions," said a trader at a Japanese trust bank. "Hedge funds are rapidly unwinding carry trades, and Japanese institutional investors with assets abroad are buying back the yen."
The Australian <AUDJPY=R> and New Zealand dollars <NZDJPY=R -- long the bellwethers of the carry trade -- sank to two-year troughs.
