LONDON, March 26 (Reuters) - The euro rallied off a 10-month low against the dollar on Friday and core euro zone government bond prices slipped after the region's leaders and the IMF agreed a joint financial safety net for debt-laden Greece.
But the plan did not alleviate longer-term worries about Greece and other fiscally vulnerable economies in Europe such as Portugal and Spain, limiting market moves. [
]The deal offers Athens loans and cash but only as a last resort and can only be disbursed with unanimous euro zone approval.
The euro rose 0.7 percent to $1.3774 <EUR=> by 0849 GMT as the Greece deal eased pressure off the single currency.
"It's a positive that there are now more details on how the financing for Greece will be achieved," said Johan Javeus, currency strategist at SEB in Stockholm.
"The fact that there will be a mechanism in place reduces the risk of the euro zone breaking up. But going forward the market will be focusing more on whether Greece will be able to deliver the austerity measures it has promised."
The euro initially weakened on news of the Greece deal as investors took the view that IMF involvement suggested the 16-country euro zone was unable to handle its problems by itself.
But dealers later began to close out some of the bets they had made against the euro, pushing the currency up against the dollar. Dollar weakness, in turn, helped lift oil prices toward $81 and boosted gold.<XAU=>
Under pressure from the Greek debt crisis, the euro has fallen around 12 percent versus the dollar since early December, when it was trading above $1.51.
The U.S. dollar index <.DXY>, a gauge of the dollar's performance against six other major currencies, slipped 0.4 percent.
FILLING THE CRACKS
Asian share markets advanced but European shares fell <
>, led by banks due to the worries about peripheral economies in Europe."I do not think there will be too much enthusiasm for the agreement with Greece. It is just filling in the cracks rather than solving the problems," said Justin Urquhart Stewart, director at Seven Investment Management.
Greek government bonds outperformed euro zone benchmark Bunds, narrowing the gap between their yields by 12 basis points on the day to 309 bps. The cost of protecting against a Greek government debt default also fell.
Waning demand this week at auctions of U.S. Treasuries were also adding to worries about government bonds.
The benchmark yield on the 10-year U.S. Treasury note <US10YT=RR> hit a nine-month high on Thursday and it has gained 17 basis points on the week after a series of poor debt auctions.
The yield was down 2.5 basis points from late Thursday in New York, at 3.86 percent by 0910 GMT.
Meanwhile, U.S. crude for May delivery <CLc1> rose for the first time in three days, gaining 55 cents to $81.08 a barrel, while ICE Brent <LCOc1> climbed 52 cents to $80.13 in London.
