Asean might get heavier hit

In a report released Sunday, the World Bank predicted that the global economy would shrink in 2009 for the first time in more than half a century and forecast that global trade would decline for the first time since the early 1980s.

“Depreciation isn’t enough now to offset the global contraction,” said Mr. Setser, noting that export powers like Japan, Korea, Taiwan and Brazil have had rapid declines in sales in recent months. “Everybody’s looking vulnerable. All commodity exporters are potentially subject to currency crises.”

Fears are growing that a much broader group of countries will plunge into trouble. Mr. Prasad’s list of potential danger zones includes Vietnam, the Philippines, Malaysia and Indonesia, as well as Pakistan and Ecuador.

In the Asian financial crisis, countries at the center of the storm were particularly vulnerable because the values of their currencies were mostly pegged to the dollar. Once central banks ran out of dollars to exchange for their own currencies, they lost their ability to influence the exchange rate. As a result, their currencies fell, turning already large debts into impossible debts.
