LONDON, Jan 8 (Reuters) - Global stocks rose on Friday, anticipating an improvement in U.S. monthly jobs data, while the dollar fell from a four-month high against the yen after Japan's new finance minister backed off his call for a weaker currency. Crude oil prices <CLc1> slipped, extending losses the previous day on worries about tighter Chinese monetary policy. Yields on safe-haven government bonds ticked higher. The latest Reuters poll suggested the U.S. economy stopped shedding jobs in December, as investors were more optimistic about the world's largest economy.
A poll of 84 economists on Thursday forecast non-farm payrolls, due at 1330 GMT, would be flat in December after dropping by 11,000 in November, far fewer than in previous months. [
]U.S. President Barack Obama will make a statement on the economy at 1940 GMT.
The jobs report "is hopefully going to show us a steadily improving trend which will give us a bit more confidence," said Justin Urquhart Stewart, director at Seven Investment Management.
Global equities measured in the MSCI All-Country World Index <.MWID00000PUS> rose 0.2 percent, hovering near a 15-month high.
In Europe, the FTSEurofirst 300 <
> added 0.6 percent and Japan's Nikkei average < > gained 1.1 percent, hitting its highest close in 15 months.U.S. stock index futures <DJc1> <SPc1> <NDc1> were flat to up 0.1 percent.
However, a strong jobs report would raise speculation that the U.S. Federal Reserve could start tightening and even increase interest rates sooner than expected.
James Bullard, president of St. Louis Federal Reserve Bank, said uncertainty about inflation was mounting in the United States, although price pressure remain subdued. [
]Overnight, other senior Fed officials placed different emphasis on inflation risks, with one warning failure to withdraw support policies soon enough could trigger inflation while another played down such risks. [
]Separately, data showed British factory gate inflation rose more than expected in December and at its fastest annual rate in nearly a year, while South Korea's central bank underscored its intention to raise rates as soon as February.
DOLLAR EASES VS YEN
The dollar dipped 0.1 percent against the yen <JPY=> to 93.19 after Naoto Kan, Japan's new finance minister, backed away from his call for a weaker yen and said currency levels should be determined by markets. [
]The greenback was also weaker against the euro <EUR=> at $1.4307, though the dollar <.DXY> was flat versus a basket of major currencies.
"The expectation is for the dollar to continue strengthening on the back of payrolls," said Lee Hardman, currency economist at Bank of Tokyo-Mitsubishi UFJ. "The dollar could see some setback on a weaker reading, but that would just be a good opportunity to buy dollars."
Oil prices were down 0.2 percent at $82.50 a barrel on concerns over tighter Chinese monetary policy.
China's Vice-Governor Yi Gang said in comments posted on Friday that the Chinese central bank will further improve the effectiveness of its monetary policy implementation, making it more targeted, while maintaining its appropriately loose stance.
Gold prices <XAU=>, deemed as a safe asset, also eased.
Yields on benchmark 10-year U.S. Treasuries <US10YT=RR> were up 2 basis points at 3.851 percent, while those on 10-year Bunds <EU10YT=RR> were also up 2 basis points at 3.392 percent. (Additional reporting by Joanne Frearson and Tamawa Desai in London; editing by Ron Askew)
