(Updates prices, adds comment)

NEW YORK, Jan 29 (Reuters) - The dollar and yen rose broadly on Thursday as bleak U.S. economic data and falling share prices kept investors wary of risk even as countries embraced more monetary and fiscal stimulus to boost growth.
The euro shed more than 1 percent to fall below $1.30 <EUR=> and plunged against the yen after billionaire investor George Soros, cited by Bloomberg, told an Austrian newspaper that the currency may not survive without a European Union plan to deal with toxic debt.
A warning from European Central Bank President Jean-Claude Trichet that the ECB could push interest rates below 2 percent and use other measures to boost growth hit the euro, as did data showing the biggest monthly jump in German unemployment in four years.
"The euro is getting pounded because it is not so clear that officials will be able to coordinate effective policy in this crisis," said Boris Schlossberg, chief currency strategist at GFT Forex in New York. "You see flows into the dollar because there's a greater sense of confidence that the United States will persevere."
The euro was down 1.2 percent at $1.2975 <EUR=> after earlier falling to $1.2934. Against the yen, it was off 1.9 percent at 116.46 <EURJPY=>. The dollar fell 0.7 percent to 89.74 yen <JPY=>.
The yen tends to advance when risk appetite fades because investors unwind trades financed with cheaply borrowed yen.
The dollar attracted buyers despite another batch of grim U.S. data that underscored the weakness of the U.S. economy.
Reports showed jobless rolls hitting a record high, orders for big-ticket items such as appliances falling for a fifth straight month in December and sales of new homes plunging 14.2 percent to a record low.
But plans for robust U.S. fiscal spending and the Federal Reserve's move to bring interest rates down near zero last month have spurred hopes of a second-half U.S. recovery.
The Fed said this week it is ready to buy long-dated Treasury debt but did not offer details on timing.
"The market must clear before we can have a recovery and the plans are in place by the Fed to lower rates and provide liquidity," said Brian Taylor, head currency trader at M&T Bank in Buffalo, New York. "What the U.S. is doing is far ahead of other countries right now."
That contrasts with the ECB approach, which has been slower to reduce rates. Trichet has indicated that the next rate move would not come until March, though in remarks to CNN on Thursday, he said rates may still fall below the current 2 percent and said officials could use unconventional means to boost growth.
"A lot of people thought that the ECB was ruling out quantitative easing, but Trichet's comments suggest otherwise," said Adarsh Sinha, currency strategist at Barclays in London.
Sterling rose 0.7 percent to $1.4310 <GBP=>, boosted by currency flows that outweighed weak UK data. The euro fell 1.8 percent to 90.75 pence <EURGBP=>.
The New Zealand dollar fell to $0.5127, the lowest since December 2002, according to Reuters data, after the central bank cut interest rates by 150 basis points to 3.5 percent and hinted at more cuts. (Additional reporting by Nick Olivari and Gertrude Chavez-Dreyfuss; Editing by Dan Grebler)
