A falling greenback is often good for the creating world. As a result of poor international locations borrow extra within the dollar than wealthy ones, their debt payments change into much less burdensome. On the identical time, imports change into cheaper, offering a balm to overseas reserves which can be typically stretched, and traders change 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 grew to become unexpectedly flush).
