Could there be another crisis in the euro zone, like the one in 2010-2013?
The euro-zone crisis from 2010 to 2013 was a balance of payments crisis (a “sudden stop”): the peripheral countries’ external deficits could no longer be financed; these external deficits therefore had to disappear, which in a currency area is obtained through a contraction in domestic demand caused by the rise in interest rates. As long as a country has an external surplus, i.e. a savings surplus, it is unlikely to suffer a balance of payments crisis or a domestic debt crisis, since the savings surplus at equilibrium must be lent and since there is a preference for domestic financial assets. For a crisis to occur, domestic savers would have to transfer a significant portion of their savings abroad, which is unlikely. A crisis could therefore reappear today in the euro zone if a country had an excessive external deficit that became difficult to finance. Currently, this could only concern France and Greece and, to a lesser degree, Portugal, but not Spain or Italy.
