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