The main problem is Spain, where private and public-sector foreign debt is larger than that of Greece, Portugal, Ireland, and Italy combined, and, as in Greece, is in the neighborhood of 100% of GDP (93% to be precise). A quarter of the labor force and half of Spain’s youth are unemployed, reflecting the country’s loss of competitiveness in the wake of the real-estate bubble inflated by cheap euro credit in the pre-crisis period.
