THE 1931 collapse of the Austrian bank Creditanstalt provoked financial panic across Europe and almost single-handedly turned a bad downturn into the Great Depression. Last week, when I read about the brewing European banking crisis, I suddenly began to dread that history might be repeating itself.

You might think that my worries are a bit late. After all, losses on subprime mortgages in the United States have already caused a Depression-like banking collapse. Well, believe it or not, Europe’s current crisis is scarier. For while losses on Eastern European debts may be only a small fraction of those on subprime mortgages, the continent’s problems are politically harder to solve, and their consequences may prove to be much worse.

Much as in our subprime mess, Eastern Europe’s problems began with easy credit. From 2004 to 2008 Eastern Europe had its own bubble, fueled by the ready availability of international credit. In recent years countries like Bulgaria and Latvia borrowed annually the equivalent of more than 20 percent of their gross domestic product from abroad. By 2008, 13 countries that were once part of the Soviet empire had accumulated a collective debt to foreign banks or in foreign currencies of more than $1 trillion. Some of the money went into investment, much of it into consumption or real estate.

When the music stopped last year and banks retrenched, the flow of new capital to Eastern Europe came to an abrupt halt, and then reversed direction. This credit crunch hit the region just as its main export markets in Western Europe were going into free fall. Moreover, with so much of the debt denominated in foreign currencies, everyone in Eastern Europe has been scrambling to get their hands on foreign exchange and local currencies have collapsed.
