PARIS, Jan 15 (Reuters) - European stocks are set to dip on Tuesday, with a blue-chip index hovering around a major resistance level, as comments from U.S. Federal Reserve Chairman Ben Bernanke failed to reassure investors on the outlook for the U.S. economy and the country's debt ceiling talks. At 0727 GMT, futures for Euro STOXX 50, for Germany's DAX and for France's CAC were down around 0.2 percent. Bernanke gave a cautiously optimistic outlook for the U.S. economy but fell short of giving clear hints about when the central bank would start to curb its aggressive bond purchases, despite speculation that the programme will be halted this year. Growing worries about the U.S. debt ceiling negotiations also kept investors on edge, with Bernanke urging lawmakers to lift the country's borrowing limit to avoid a potentially disastrous debt default. The United States scraped up against its $16.4 trillion debt ceiling on December 31 and is now employing special measures to meet its financial obligations. The Treasury Department said those steps could be exhausted by mid-February. "The dawning realisation that we are in for a re-run of the recent 'down to the wire' fiscal cliff showdown is once again set to keep traders in a bipolar mental state regarding the U.S., and thus global, economy," London Capital Group dealer Jonathan Sudaria wrote in a note. The euro zone's blue chip Euro STOXX 50 index has gained about 3 percent since the start of the year, but has failed to break above a key resistance zone at 2,710-2,720, which represents the starting point of the index's 30 percent plunge in mid-2011 during the heat of the euro zone debt crisis. Despite the pause of the past few days, Aurel BGC chartist Gerard Sagnier sees more potential on the upside for equities. "Volumes are low, there's no selling pressure, and the market is awaiting a catalyst to start rallying again. The potential is clearly on the upside, and we recommend buying all the dips," he said.

On the macro front, investors awaited Germany's GDP numbers for 2012, due at 0800 GMT, looking for insight on the extent of the damage on the German economy from the recession in most of Europe. -------------------------------------------------------------------------------- MARKET SNAPSHOT AT 0728 GMT LAST PCT CHG NET CHG S&P 500 1,470.68 -0.09 % -1.37 NIKKEI 10,879.08 0.72 % 77.51 MSCI ASIA EX-JP 558.16 -0.53 % -2.99 EUR/USD 1.3345 -0.28 % -0.0037 USD/JPY 88.79 -0.75 % -0.6700 10-YR US TSY YLD 1.832 -- -0.02 10-YR BUND YLD 1.537 -- -0.02 SPOT GOLD $1,674.80 0.48 % $8.00 US CRUDE $93.77 -0.39 % -0.37 > GLOBAL MARKETS-Nikkei up on yen weakness, Asian shares cautious > Apple drags on S&P, Nasdaq; Dell jumps after report > Nikkei hits 32-month high on weak yen; Sharp down on Apple report > TREASURIES-U.S. bonds firmer, seen supported by Fed purchases > Yen rebounds on Japan Amari's comments, dlr struggles after Fed > Platinum hits 3-mth high on supply worry; Tokyo gold at record > METALS-Copper climbs as Fed comments erode dollar > Brent holds above $111; US debt, forecast oil stocks gain weigh COMPANY NEWS: RIO TINTO, MINING SECTOR Rio Tinto said it aims to boost iron ore output by 15 percent this year after production in 2012 climbed to 253 million tonnes, beating its own target, as resurgent Chinese demand drives a price recovery.
