I think the US admin is pursuing an uncfoifial weak dollar strategy in the hope it will revive the US economy by boosting exports. When the dollar falls against other currencies, it makes US exports less expensive in foreign currencies, leading to more exports to foreign companies than would otherwise be the case. The downside is that such a policy is inflationary, as imports correspondingly become more expensive. Another danger is that this policy will make US exporters complacent, with them relying on the continuation of the weak dollar to keep their prices competitive, leading to them getting a bloody-nose' when the dollar strengthens again in the future, making their exports more expensive and forcing them to restructure to cut costs they should have done earlier. The Eurozone was in this situation some years ago with a shortlived fall in unemployment when the Euro was weak in the first few years, which was largely reversed when the Euro started becoming strong. Thankfully this forced the German govt to introduced economic reforms to help cut costs for businesses, and unemployment has fallen in a more sustained way. I think a strong currency helps force govts to deregulate and cut costs for businessesm while a weak one may be good in the beginning for sectors of the economy but in the longterm can breed complacency, inflation and unemployment when the fall in the exchange-rate is reversed.
