LONDON, Feb 11 (Reuters) - World stocks held near a one-week high while the euro rose broadly on Thursday after euro zone leaders flagged that a deal had been reached to help Greece tackle its debt and deficit problems.
The premium investors demand for holding Greek debt rather than safer German bonds fell and the default insurance cost for Greek debt also eased as European Union President Herman Van Rompuy said several key euro zone officials have reached a deal in Brussels to help Greece. [
]Concerns over the crisis in Greece and other highly indebted euro zone nations, along with expectations that U.S. interest rates would rise at some point, had weighed on the euro and global stocks in recent sessions.
"European authorities look to have been backed into a corner to such an extent that they really do need to deliver something, either a concrete plan or a strongly worded statement," said Tom Levinson, currency strategist at ING. MSCI world equity index <.MIWD00000PUS> rose 0.5 percent while the FTSEurofirst 300 index <
> gained 0.7 percent. Rio Tinto <RIO.L> rose more than 4 percent at one point after its second half profits beat analysts' forecasts.U.S. stock futures rose around half a percent <SPc1>, pointing to a firmer open on Wall Street.
The euro rose 0.1 percent to $1.3745 <EUR=> after hitting an 8-1/2 month low last week. The Greek/German 10-year bond yield spread fell 17 basis points to 266 bps. Greek five-year credit default swaps also fell to 332.5 bps from 340.1 bps.

Emerging stocks <.MSCIEF> rose 1.1 percent.
U.S. crude oil <CLc1> rose 1 percent to $75.32 a barrel after the U.S. Energy Information Administration raised forecasts on oil prices and world oil demand in 2010.
German government bond futures <FGBLc1> fell 37 ticks.
The dollar <.DXY> fell 0.2 percent against a basket of major currencies, erasing gains made after Bernanke's speech.
Federal Reserve chairman Ben Bernanke said on Wednesday the Fed would likely begin tightening monetary policy by removing some of the cash from the financial system before it turns to raise benchmark short-term interest rates.
In his most comprehensive description to date of how the Fed aims to dismantle emergency economic support, Bernanke said the central bank could soon raise the discount rate it charges banks for emergency loans, but stressed that would not be akin to a tightening in monetary policy.
"The U.S. is pointing towards normality. Thus it is no longer clear that the dollar is the most obvious funding currency for risky investment," RBS said in a note to clients.
