* Euro rises 0.6 percent but off early highs

HONG KONG/SYDNEY, May 10 (Reuters) - The euro firmed and stocks rose on Monday after the European Union agreed on a 500 billion euro ($670 billion) emergency fund as it struggles to keep Greece's debt problems from spreading to other countries.
Major global central banks moved swiftly to support Europe, re-establishing dollar swap facilities used during the 2007-2008 financial crisis to help ease strains on financial markets and ensure there was enough liquidity to keep global credit markets from seizing up.
The euro <EUR> rose as high as $1.2950 on news of the deal before slipping back after the European Central Bank said it would buy euro zone government and private debt, abandoning resistance to full-scale bond purchases in light of Greece's debt crisis. [
]By midmorning, the single currency was up 0.6 percent on the day at $1.2828 <EUR=>, and was 1.5 percent higher against the yen at 118.55 yen <EURJPY=R>. [
]The EU plan was a mix of loans and loan guarantees, an EU diplomat said.
Goldman Sachs said in a report before the plan was formally announced that the package was impressive if confirmed.
Financial markets have been punishing heavily indebted euro zone members, threatening to plunge them into the same sort of crisis as Greece and possibly jeopardising the global economic recovery.
The new safety net was meant to protect other countries with bloated budgets, such as Portugal, Spain and Ireland.
Jitters over euro zone finances have battered global markets as investors dump riskier assets for safer ones such as the U.S. dollar, creating fears of dollar shortages in some countries and driving up dollar funding costs.
* The euro <EUR=> climbed as far as $1.2950 before paring gains but remained well off 14-month lows of $1.2520 hit last week as fears of a euro zone sovereign debt crisis escalated.
* The MSCI world stock index <.MIWD00000PUS> rose 0.6 percent, with the MSCI Asia ex-Japan index <.MIAPJ0000PUS> up 1.7 percent.
* Japan's stock market opened higher with the Nikkei benchmark <
> up 1.3 percent. The June S&P futures contract <SPc1> was up 2.3 percent.* Before the European announcement, data from the Commodity Futures Trading Commission showed euro sceptics were not easily won over, with bets against the common currency hitting a record high in the week ending May 4. [
]* Oil <CLc1> was up 1.74 percent at $76.42, off a near-three-month low struck Friday.
* Gold <XAU=> was softer at $1,198.20, pulling back from a near record-high of $1,213.35 hit Friday.
* The U.S. dollar was firmer against the yen at 92.24 <JPY=> and well off Friday's five-month lows of 88.00.
* U.S. Treasuries <0#USBMK=> were broadly weaker amid optimism about the plan adding to Friday's losses after the U.S. Labor Dept reported larger-than-expected employment gains in April, suggesting the economic recovery was well underway.
