A falling greenback is generally good for the creating world. As a result of poor international locations borrow extra within the dollar than wealthy ones, their debt payments develop into much less burdensome. On the similar time, imports develop into cheaper, offering a balm to international reserves which can be typically stretched, and buyers develop into extra optimistic. So it was from 1971 to 1978 (the final time poor international locations actually splurged on infrastructure) and from 2004 to 2008 (when commodity exporters turned unexpectedly flush).
