HONG KONG, Jan 2 (Reuters) - Asian shares rallied on Friday, starting the new year on hopes the worst of the global crisis may be over after a brutal 2008, while safe-havens such as U.S. Treasuries fell as investors showed signs of taking on risk.
Still, data on Friday signalled a tough road ahead for large parts of the world given that major economies from the United States to Japan are stuck in recession after experiencing the worst financial crisis in generations.
The euro and the South Korean won fell on concerns about weakening economic growth, while crude oil prices tumbled more than $2 a barrel, cutting into a rally of about 14 percent on the final trading day of 2008.
European stocks were seen little changed on Friday in their first session of the new year. Euro zone and U.S. manufacturing activity data for December is due later in the day.
A recovery in global markets will hinge on whether investors become willing to wean themselves off assets seen as safer, such as U.S. Treasuries, which have outperformed despite offering the lowest yields in decades.
Policy makers have slashed interest rates and pledged to spend to try to fight off the economic slowdown, which supported sentiment on Friday.
"General hopes about the new year, such as that the real effects of global governments' economic stimulus measures will be felt, are boosting stocks," said Yun Lee, a market analyst at Woori Investment & Securities in Seoul.

ECONOMIC WORRIES REMAIN
The gains in Asian shares came despite a continued raft of bleak economic data, as consumers worldwide pare their spending and companies reduce output, setting off fears about jobs and deflation.
South Korea said on Friday exports tumbled 17.4 percent in the year to December, while data showed a recession in Singapore deepened in the fourth quarter leading the government to cut its growth forecast for 2009. [

Benchmark 10-year notes <US10YT=RR> fell 10/32 to yield 2.251 percent. That meant the yield rose 5 basis points from U.S. trade on Wednesday, and 20 basis points over the past two trading days, recovering after touching five-decade lows last month.
Two-year notes <US2YT=RR> were flat to yield 0.768 percent.
Considerable uncertainty remains in financial markets about how effective stimulus measures and low interest rates will be in stimulating global growth.
U.S. President-elect Barack Obama, who takes office this month, has pledged to deliver a stimulus package that aims to generate 3 million new jobs. It may be worth $775 billion or more.
EURO FALLS
The euro fell on expectations that the euro-zone economy will suffer for longer because of the European Central Bank's reluctance to cut interest rates as aggressively as other central banks.

Concerns over global demand hit oil prices <CLc1>, which slumped $2.06 to $42.54, after crude on Wednesday surged $5.57 when a slowdown in U.S. refinery activity had sparked fears of tightening fuel supply this winter.
Gold gave up some of its early gains on Friday, but analysts said the dollar's recent weakness and expectations of more grim U.S. economic data could still ignite safe-haven buying.
