Fourth, I believe we need better
international mechanisms to cushion the adjustment process for
when capital flows abruptly change direction.
Except for a period in the early 1960s,
when Robert Triffin explored what became known as the Triffin Dilemma, in which foreign hoarding of U.S. dollars was linked to persistent U.S. trade deficits, the relationship between the
capital and current accounts seems since then to have mystified most economists, including those specializing in trade, even as U.S. trade deficits and foreign
capital inflows soared, and as the growth in
international capital flows, once consisting largely of trade finance, exploded relative to trade
flows and relegated trade finance to minor importance.
