Donald Trump wants a weaker dollar. What are his options?

Despite the seeming success of the “Plaza Accords”, currency intervention fell out of favour. Desire for control over monetary policy, as a way to keep inflation low, took precedence. It is infeasible for a country to have an independent monetary policy, an open capital account and a fixed exchange rate; even going for two of the three, and influence over the third, is not much easier. Currency markets are vast, deep and liquid. Time and again foreign-exchange traders have beaten into submission policymakers who have dared try to push them around, in either direction.
