With Greek stocks tumbling to 20-year lows and political turmoil putting the country's austerity measures in jeopardy, analysts fear Greece's problems could spread far beyond its borders.

Two days after Greek voters sent a punishing message to mainstream parties, a fractured landscape of left-wing, anti-austerity groups struggled to form a new government.

Rejecting the austerity measures would likely lead to bankruptcy and Greece's ouster from the European Union.

Alex Tsipras, leader of the Radical Left Coalition party, called the austerity measures "destructive."

"The pro-bailout parties no longer have a majority in parliament to vote in destructive measures for the Greek people," Tsipras said.

Tsipras is the second leader to attempt to form a government, and it's unclear if he'll succeed. Among the minor parties trying to unite are Stalinists and neo-Nazis.

If none of the party leaders manage to form a government, new elections will be held next month.

The uncertainty about Greece's political future, its spiralling economic problems and the impact of its austerity measures has doubled the number of suicides in the past year.

"The economic catastrophe we are experiencing has given rise to the problem of suicide," said psychologist Aris Violatzis.

Last month, 77-year-old Dmitris Christoulas fatally shot himself in front of the Greek Parliament. Cuts to his pension had forced him to sift through garbage for food.

In a suicide note, he said killing himself was his only dignified option.

The European Union says the austerity measures are the only way to save Greece's economy, and prevent it from pulling down other members of the eurozone.

German Chancellor Angela Merkel has taken a hard-line stance, saying there will be no more bailouts for Greece unless the austerity measures continue with the next government.

However, uncertainty is already hitting the global markets. On Tuesday, Canada's S&P/TSX composite index dropped 155.91 points -- 1.3 per cent -- to finish the day at 11,704.74.

In the U.S., the Dow Jones average dropped 76.44 points to 12,932.09, while the Nasdaq composite index slipped 11.49 points to 2,946.27.
