Greece appears to have averted imminent default, but its recovery prospects remain clouded by the severity of its planned austerity measures and the impact cutbacks have already had on its stricken economy.

Philip Stephens discusses two measures necessary to avoid catastrophic economic collapse in Greece and its implications for European solidarity in this Financial Times piece.

Even as Greek leaders agree to new austerity measures, the IMF is calling on Greece's official creditors to take losses on its bond holdings. Analysts and policymakers increasingly question the wisdom of EU-mandated austerity measures at the expense of growth.

Policymakers and market actors are increasingly concerned about a disorderly Greek default, while many analysts question the wisdom of Germany's strict austerity approach to the escalating eurozone sovereign debt crisis.
