HONG KONG, Sept 5 (Reuters) - Investors dumped euros and shares on Friday as U.S. economic troubles made bets on growth elsewhere look too risky, sending stocks to their lowest in two years while triggering a surge in safe-haven government bonds.

The ratcheting up of fear followed a 3 percent sell-off on Wall Street on Thursday, the steepest decline for more than two months, prompted by an unexpected jump in jobless claims and nervousness ahead of monthly employment data on Friday. [ID:nN04295126]

European shares opened lower, adding to Thursday's steep losses. Germany's DAX .GDAXI and France's CAC 40 .FCHI benchmark stock markets both opened more than 0.5 percent lower.

The renewed jitters sent the yen soaring as investors unwound carry trades, ditching bets in which they had borrowed the Japanese currency to buy euros or high-yielding Australian or New Zealand dollars.

"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 euro hit a 13-month low around 150.60 yen before pulling back to 152.75 yen EURJPY=R, having recorded a 3.6 percent drop on Thursday -- its biggest one-day fall since a massive carry-trade unwind in 1998.

"Position unwinding is taking place globally and it is becoming a big wave," said Tokichi Ito, deputy general manager of foreign exchange at the Trust & Custody Services Bank in Japan.

The Australian AUDJPY=R and New Zealand dollars NZDJPY=R -- long the bellwethers of the carry trade -- sank to two-year troughs against the Japanese currency.

The prospect of less competitive exports to Europe, as well as growing gloom about the global economy, hit Japanese shares such as Mizuho Financial Group (8411.T) and Sony Corp (6758.T), which fell 6.6 percent and 4.4 percent, respectively.

Japan's Nikkei average .N225 fell 2.8 percent to a 5-½ month closing low, while stocks elsewhere in the Asia-Pacific, gauged by MSCI's index .MIAPJ0000PUS were down 2.7 percent.

The MSCI All-Country World index .MIWD00000PUS, down 0.6 percent, plumbed its lowest level since August 2006.
