【明報專訊】NO SOONER had Alexis Tsipras (habitually tieless) been elected Greek prime minister amid anti-austerity clamours than Europe was plunged into anxiety. The euro once dropped below 1.10, and share prices have kept falling in Greece. In the first three days after Syriza, which Tsipras heads, had taken office, uncertainty sent prices of bank shares down over 40%. The reason why there have been such negative reactions is that Europeans are worried that Tsipras, who has come to power by virtue of anti-austerity sentiment, may flagrantly have Greece repudiate its debts and leave the eurozone. Though it is said that Greece's departure should cause no fear as a firewall has been put in place in Europe, people cannot but be perturbed and thrown into disarray.
