* ECB holds rates at 0.75 percent * ECB cuts inflation, growth outlook * Political tension in Italy grows NEW YORK, Dec 6 The euro was on track for its sharpest drop against the dollar in a month on Thursday after comments from the European Central Bank chief and a downgrade to the region's growth and inflation forecasts boosted expectations of an interest rate cut. Political chaos in Italy drove Italian bond yields higher and added to losses in the euro. Silvio Berlusconi's People of Freedom party withdrew its support for Italy's Prime Minister Mario Monti on Thursday, setting up a conflict that could force an early election. ECB President Mario Draghi, speaking at a news conference after the bank's decision to keep its main interest rate at 0.75 percent, said a wide discussion on rates had preceded the consensus decision. "That could be the signal that 2013's first ECB monetary decision could include another cut in interest rates," said Neal Gilbert, market strategist at GFT in Grand Rapids, Michigan. "The underlying reason for euro weakness is still there, and the ECB's warnings of continued weakness over the next year could be the catalyst for a continued euro drop." Draghi's comments came as the ECB predicted the euro zone economy would shrink again in 2013 and sharply lowered its growth and inflation forecasts. It also said risks to growth remained on the downside. The bank forecast gross domestic product in a range of falling by 0.9 percent to growing just 0.3 percent next year, suggesting contraction was far more likely than not. It predicted inflation at 1.1 percent to 2.1 percent next year. "The combination of the ECB's cooler growth and inflation forecasts opened the door to a rate cut in the months ahead," said Joe Manimbo, senior market analyst at Western Union Business Solutions in Washington. Draghi also said policymakers discussed setting a negative rate on the ECB's deposit facility in an attempt to encourage banks not to hoard cash at the ECB but lend it into the real economy instead. The euro fell as low as $1.2948 on Reuters data and was last down 0.8 percent at $1.2959. At current levels, it is on track for the biggest daily percentage fall since Nov. 2. The euro lost 1 percent to 106.68 yen. Italian and Spanish government bond yields rose on tensions in Italy. A disappointing Spanish bond sale on Wednesday also weighed as it revived talk of an official bailout request from the euro zone's fourth-largest economy. "Some analysts are predicting Italy could be contracting by as much as negative 3 percent next year. If that's the case, then they could become another financing crisis for the euro zone," said Boris Schlossberg, managing director of FX Strategy at BK Asset Management in New York. Investors are shifting attention to Friday's closely watched government report on U.S. nonfarm payrolls for November. Payrolls likely rose only 93,000 last month after advancing 171,000 in October, according to a Reuters survey of economists. The unemployment rate is seen holding steady at 7.9 percent. "After selling off as a result of comments coming out of the ECB conference, euro/dollar has found support around the 1.2970s which is very close to key support of 1.2950," said Marc Principato, Director of SMB Forex Trading And Education in New York. "I am looking for price stability around this level as we await the NFP report tomorrow." Some analysts said that while the outlook for the euro zone remained bleak, euro losses against the dollar could be limited. "As we expect the (Federal Reserve) to announce a shift to outright Treasury purchases next week, the U.S. dollar should remain soft," said Vassili Serebriakov, currency strategist at BNP Paribas in New York. The Fed holds its December policy meeting next week. BNP forecasts the euro at $1.33 by the end of the year. The dollar slipped 0.2 percent to 82.33 yen, still not far from the 82.82 touched on Nov. 22 which was the highest since early April. Traders expect the yen to remain under pressure on expectations of further monetary easing by the Bank of Japan following an election on Dec. 16. The Australian dollar rose to a 2-1/2-month high after surprisingly strong Australian jobs data prompted investors to reduce expectations of further policy easing. It was last up 0.2 percent at $1.0477.
