TOKYO, April 23 (Reuters) - Stop-loss selling hammered the euro to a one-year low on Friday on growing speculation that debt-laden Greece could default on its sovereign debt.
Asia stocks mostly drifted lower, but were supported by strong earnings predictions as most companies globally have met or exceeded expectations so far in the first-quarter earnings season.
Korean stocks briefly touched a 22-month high after forecast-beating results from several major firms, including Hyundai Motor, before slipping lower.
The euro <EUR=> dropped as far as $1.3201 on trading platform EBS, its lowest level since April 30 last year, after the European Union said Greece's budget deficit was worse than feared at 13.6 percent of GDP and Moody's Investors Service cut its rating of Greek government debt. [
] [ ]"The euro is getting clobbered as worries about Greece are intensifying and fears of a contagion are rising," said David Scutt, a forex trader at Arab Bank Australia in Sydney.
"There were quite a few stops taken on its way down this morning and we have to see if $1.32 gives way later in the day when flows get better."
Moody's downgraded Greece's sovereign debt rating by a notch to A3 and placed the rating on review for a further possible downgrade, citing the risk that Greece may end up paying a lot more for its borrowing than initially thought.
A Reuters poll of around 50 economists gave a median 80 percent chance that Greece would turn to its euro zone partners in the next two months and activate its aid package.
They gave a roughly one-in-four chance that Greece would default on its debt in the next five years. [
]By mid-morning Asia time, the euro had rebounded to $1.3220. It fell 0.5 percent against the yen to 123.54 yen <EURJPY=R>.
The euro's broad weakness helped the dollar index <.DXY>, a basket of six major currencies, rise 0.5 percent to 88.991. It rose earlier to its highest level since March 25.
The dollar also got a general boost from a fall in U.S. jobless claims and rise in home sales, bolstering the view that the economy is improving. [
