Europe struggles with rescue fund, may turn to IMF

Euro zone ministers struggled to ramp up the firepower of their rescue fund and raised the possibility of asking the IMF for more help on Tuesday after Italy's borrowing costs hit a euro lifetime high of nearly 8 percent.

Two years into Europe's sovereign debt crisis, investors are fleeing the euro zone bond market, European banks are dumping government debt, deposits are draining from south European banks and a looming recession is aggravating the pain, fuelling doubts about the survival of the single currency.

Italy had to offer a record 7.89 percent yield to sell 3-year bonds, a stunning leap from the 4.93 percent it paid in late October, and 7.56 percent for 10-year bonds, compared with 6.06 percent at that time.

The yields were above levels at which Greece, Ireland and Portugal were forced to apply for international bailouts, but European stocks and bonds rallied in apparent relief at the strong demand, with the maximum 7.5 billion euros sold.

"In an ideal world, these yields ... would serve to give the Ecofin/Eurogroup a sense of added urgency, but this is a far from ideal world," said Peter Chatwell, rate strategist at Credit Agricole in London.

The euro had earlier dipped on a report in business daily La Tribune that ratings agency Standard & Poor's would lower its outlook on France's AAA credit rating to negative within 10 days, dealing a potential body blow to the euro zone's ability to rescue heavily indebted countries.
