Krugman cites a 2005 speech Ben Bernanke made as the best explanation for the global economic crisis. In his speech, Bernake said in the mid-1990s, the emerging economies of Asia were major importers of capital, borrowing from other countries to finance their development. After their own financial crisis in 1997-98, Asian countries began protecting themselves by acquiring foreign assets, "in effect exporting capital to the rest of the world."
The result was a world awash in cheap money, looking for somewhere to go.
Most of that money went to the United States — hence our giant trade deficit, because a trade deficit is the flip side of capital inflows. But as Mr. Bernanke correctly pointed out, money surged into other nations as well. In particular, a number of smaller European economies experienced capital inflows that, while much smaller in dollar terms than the flows into the United States, were much larger compared with the size of their economies.
Still, much of the global saving glut did end up in America. Why?
Mr. Bernanke cited “the depth and sophistication of the country’s financial markets (which, among other things, have allowed households easy access to housing wealth).” Depth, yes. But sophistication? Well, you could say that American bankers, empowered by a quarter-century of deregulatory zeal, led the world in finding sophisticated ways to enrich themselves by hiding risk and fooling investors.
And wide-open, loosely regulated financial systems characterized many of the other recipients of large capital inflows. This may explain the almost eerie correlation between conservative praise two or three years ago and economic disaster today. “Reforms have made Iceland a Nordic tiger,” declared a paper from the Cato Institute. “How Ireland Became the Celtic Tiger” was the title of one Heritage Foundation article; “The Estonian Economic Miracle” was the title of another. All three nations are in deep crisis now.
For a while, the inrush of capital created the illusion of wealth in these countries, just as it did for American homeowners: asset prices were rising, currencies were strong, and everything looked fine. But bubbles always burst sooner or later, and yesterday’s miracle economies have become today’s basket cases, nations whose assets have evaporated but whose debts remain all too real. And these debts are an especially heavy burden because most of the loans were denominated in other countries’ currencies.
Nor is the damage confined to the original borrowers. In America, the housing bubble mainly took place along the coasts, but when the bubble burst, demand for manufactured goods, especially cars, collapsed — and that has taken a terrible toll on the industrial heartland. Similarly, Europe’s bubbles were mainly around the continent’s periphery, yet industrial production in Germany — which never had a financial bubble but is Europe’s manufacturing core — is falling rapidly, thanks to a plunge in exports.
If you want to know where the global crisis came from, then, think of it this way: we’re looking at the revenge of the glut.
And the saving glut is still out there. In fact, it’s bigger than ever, now that suddenly impoverished consumers have rediscovered the virtues of thrift and the worldwide property boom, which provided an outlet for all those excess savings, has turned into a worldwide bust.
One way to look at the international situation right now is that we’re suffering from a global paradox of thrift: around the world, desired saving exceeds the amount businesses are willing to invest. And the result is a global slump that leaves everyone worse off.
So that’s how we got into this mess. And we’re still looking for the way out.
