* Analysts say injection of 500 bln euros priced in

LONDON, Feb 28 (Reuters) - The euro rose broadly on Tuesday, moving within sight of a near three-month high against the U.S. dollar ahead of an injection of cheap cash by the European Central Bank that could boost risk appetite and the common currency in the near term.
It also advanced against the yen, although it stayed well below a four-month peak. The yen pulled away from a 9-month low against the dollar reached the day before on month-end buying by Japanese exporters, although short-covering by hedge funds saw it relinquish most of those gains.
Currency investors sidestepped news that Standard & Poor's cut its ratings on Greece to "selective default" as Athens' efforts to lighten its debt burden was largely expected to trigger the downgrade.
Still, many were cautious about pushing the euro too much higher ahead of an ISDA ruling on Wednesday. The derivatives body will rule whether a Greek credit event has taken place after the country began a bond swap process.
The euro stood at $1.3455, up 0.4 percent on the day, trading not far from a near three-month peak of $1.3487 set on Friday. Immediate support for the common currency is seen in the $1.3357-66 area around recent lows, with $1.3291 marking the 38.2 percent retracement of the Feb. 16-24 rise.
"The euro has priced in a cash injection of 500 billion euros and anything above 600 billion will be risk positive and push the euro higher," said Ankita Dudani, G-10 currency strategist at RBS Global Banking.
On the other hand, a take up of less than 400 billion will hurt risk appetite and could drag the euro lower, she added.
A Reuters poll of money traders showed banks will take up half a trillion euros of ECB funds, roughly the same as the previous offering last year. This is seen as buying more time for authorities to sort out the sovereign debt crisis.
Beyond the ECB's long term refinancing operation, prospects for the euro look rather dim, given chances of further rating downgrades, worries that peripheral countries will continue to struggle to meet fiscal targets and the tough austerity measures will hurt growth.
All of which could see the European Central Bank maintain an accommodative monetary policy and push it to lower interest rates in coming months, a factor that could drag the euro lower.
In contrast to the euro zone, U.S. economic activity is showing signs of a more sustained recovery, pushing yields higher, although that move seems to be running out of steam.
Higher U.S. yields and better prospects for the economy have been supporting the dollar against the yen. Also weighing on the yen and putting it on course for its sharpest monthly drop in two years is a record trade deficit, shrinking current account surplus and surprise policy easing by the Bank of Japan.
The dollar was last up 0.2 percent at 80.74 yen, having hit a nine-month high of 81.66 yen the day before. It briefly fell as low as 80.01 yen, but managed to bounce back, supported by dollar-buying by Japanese investors unwinding their currency hedges.
"The pullback is rather moderate right now and if we manage to stick above 80 yen for the rest of the day, we could see some more yen easing in the coming weeks," said Sumino Kamei, senior analyst at Bank of Tokyo-Mitsubishi UFJ in Tokyo.
The dollar's rally on Monday stalled a little above a strong technical resistance at 81.62 yen, marked by the 61.8 percent retracement of the slide from its 2011 high to that year's low. Chart supports for the dollar are seen near 80.10 yen area, including Monday's low of 80.13.
Short-covering by leveraged accounts and yen selling by Japanese importers pushed the euro up to 108.58 yen, 0.6 pct higher compared to late New York levels, but it was still well off the four-month peak of 109.95 yen hit on Monday.
The Australian dollar rose 0.2 percent to $1.0780, from Monday's low of around $1.0650, rising in line with most stock markets, but remained within its recent range of $1.0600-1.0845.
