Sentix‘s euro zone breakup index for Greece shot up to 48.3 percent in April from 35.5 percent in March, suggesting one in two investors is sceptical about pledges to keep Athens in the single currency bloc.
Greece is weeks away from running out of cash, but talks with its European Union and International Monetary Fund lenders on more aid have been deadlocked over reform measures including pension cuts and labour market liberalisation that Greece must implement.
The breakup index for the euro zone as a whole climbed to 49.0 percent in April from 36.8 percent in March, driven by the increase in expectations that Athens would quit the bloc.
That put it at about the same level as during the peak of the eurozone debt crisis in 2012.
However, Sentix‘s index measuring the risk of contagion fell to a record low of 26.1 percent, meaning that investors do not generally expect the Greek debt crisis to spread to other parts of the euro zone.
The breakup survey covered 1,023 investors conducted April 23-25. It measures the percentage of investors that expect the eurozone to break up.
