In volatile trade, the single currency briefly fell under $1.35 for the first time in a month. At 0720 GMT, the euro slipped to $1.3495 from 1.3543 in New York late Wednesday. It had edged back up to $1.3520 by 0745 GMT. The single currency also slipped to 104.99 yen from 105.38 yen in New York Wednesday. The dollar stood at 77.65 yen, edging down from 77.78 in New York. Renewed selling pressure on the euro came as Italy's 10-year government bond yield shot up to 7.4 percent, a level regarded as unsustainable for the finances of the eurozone's third-largest economy. The surging yields brought back into focus the prospect that Europe's problems could tip the global economy into a double-dip recession amid concerns that Italy is too big to bail out. "The eurozone looks horrible," said RBS head of domestic sales trading and execution, Justin Gallagher in Sydney. "Italy is the elephant in the room and their 10-year bonds going above seven percent is a major shock." Even though Prime Minister Silvio Berlusconi has pledged to resign once credible economic reforms are in place, markets remain spooked. "Investor focus has moved from Greece to Italy, and our sentiment on the euro is even worse," said Osao Iizuka, head of currency trading at Sumitomo Trust & Banking. Asian currencies slipped in favour of the safe-haven greenback as investors abandoned risk in the face of the eurozone crisis. The Australian dollar fetched $1.0128, down from $1.0351 late Wednesday. The greenback rose against its Singapore counterpart to Sg$1.2917 from Sg$1.2730 on Wednesday. The dollar also rose against the Korean won, climbing above 1,135.00 won before standing at 1,133.04 won in the afternoon compared to 1,117.40 the previous day. "In the past cases of Greece, Ireland and Portugal, they have knocked on the door of the European Financial Stability Facility when their 10-year bond yields surpassed eight percent," said Junya Tanase, chief FX strategist for JPMorgan. "We need to monitor whether Italy will follow the same path," he said. The sharp rise of the Italian bond yields drove down global stocks, with Tokyo's Nikkei index ending the morning session down 2.35 percent at 8,549.94 and Hong Kong down 4.34 percent in the afternoon. Against other major Asian currencies, the dollar rose to Tw$30.24 from 30.04 on Wednesday and to 43.27 Philippine pesos from 43.03. The unit also gained to 30.83 Thai baht from 30.65 and to 8,965.00 Indonesian rupiah from 8,922.50.
