Paul Krugman: This Age of Bubbles

So, another BRIC hits the wall. Actually, I’ve never much liked the whole “BRIC” — Brazil, Russia, India, and China — concept: Russia, which is basically a petro-economy, doesn’t belong there at all, and there are large differences among the other three. Still, it’s hard to deny that India, Brazil, and a number of other countries are now experiencing similar problems. And those shared problems define the economic crisis du jour.

What’s going on? It’s a variant on the same old story: investors loved these economies not wisely but too well, and have now turned on the objects of their former affection. A couple years back, Western investors — discouraged by low returns both in the United States and in the noncrisis nations of Europe — began pouring large sums into emerging markets. Now they’ve reversed course. As a result, India’s rupee and Brazil’s real are plunging, along with Indonesia’s rupiah, the South African rand, the Turkish lira, and more.
