As a result, many poorer Eurozone members had their credit downgraded and responded by imposing aggressive austerity measures, further stagnating their economies and fomenting political unrest. Bailout programs arranged for Italy, Ireland, Portugal, Greece, and Cyprus lasted until 2014–18, by which time economic revival and improved structural deficits in these countries had resolved the crisis.in wikipedia
