NEW YORK, Jan 12 (Reuters) - Global stocks and the euro rallied on Wednesday after healthy demand for Portugal's bond sale eased concern over the debt crisis in Europe, while a surge in corn and soybean futures powered a broad rally in commodity prices.
European stocks hit a 28-month closing high, lifted by speculation the European Union will bolster the region's rescue fund, and government bond prices dropped after the Portuguese bond auction reduced investors' appetite for safety.

"It's a bit of relief from the fear that was running really high some days ago. There was talk that Portugal could be asking for help very soon," said Klaus Wiener, chief economist at Generali Investments in Cologne, Germany.
"Equity markets are rising because we have a fairly decent global macroeconomic backdrop. The fast-growing regions are still powering ahead and we see growth accelerating in the U.S. as well," he added.
The euro jumped more than 1 percent to a session high of $1.3144 and broke above its 200-day moving average of $1.3071 on trading platform EBS. For details see [ID:nN12148673]
Still, the euro's gains could be short-lived as analysts believe the government in Lisbon will continue to struggle and still may turn to the EU and International Monetary Fund for a bailout.
"Markets are far from convinced that the crisis has begun, let alone ended," said Alan Wilde, head of fixed-income and currency at Baring Asset Management in London, which oversees $50 billion in assets.

The S&P is almost 9 percent higher since the start of December, in part on bets U.S. corporate earnings would be strong. While early results have justified that optimism, some analysts say it may be hard for equities to rise much beyond current levels.
"Sentiment has gotten heavily bullish, and eventually that will weigh on us," said Bill Stone, chief investment strategist at PNC Wealth Management in Philadelphia, where he helps oversee $105 billion in assets. "I don't think we'll get a correction, but a pullback or pause seems likely."
Gold rose to a one-week high as the dollar fell sharply against the euro but news that Europe could reach a comprehensive package in the next two months to solve the bloc's debt crisis put a damper on safe-haven demand.

Oil rose on a tighter supply outlook and after Portugal's bond sale soothed concern over the euro zone's finances, with Brent crude, the benchmark for oil trade in Europe, the Middle East and Africa, closing in on the $100 mark.

U.S. Treasury debt prices pared earlier losses from a strong bid on the sale of reopened 10-year notes.
The 3.30 ratio of bids received over those accepted was the highest since the Treasury's 10-year note auction in April, according to Treasury data.
