This paper sets out to investigate the forces and conditions that led to the emergence of global imbalances preceding the worldwide crisis of 2007–09, and both the likelihood and the potential sustainability of reemerging global imbalances as the world economy recovers from that crisis. The “Bretton Woods 2” hypothesis of sustainable global imbalances featuring a quasi-permanent US current account deficit overlooked that the domestic counterpart to the United States’ external deficit—soaring household indebtedness—was based not on safe debts but rather toxic ones. We critique the “global saving glut” hypothesis, and propose the “global dollar glut” hypothesis in its stead. With the US private sector in retrenchment mode, the question arises whether fiscal expansion might not only succeed in filling the gap in US domestic demand but also restart global arrangements along BW2 lines, albeit this time based on public debt—call it “Bretton Woods 3.” This paper explores the chances of a BW3 regime, highlighting the role of “dollar leveraging” in sustaining US trade deficits. Longer-term prospects for a postdollar standard are discussed in the light of John Maynard Keynes’s “bancor” plan.

This paper investigates the United States dollar’s role as the international currency of choice as a key contributing factor in critical global developments that led to the crisis of 2007–09, and considers the future role of the dollar as the global economy emerges from that crisis. It is argued that the dollar is likely to retain its hegemonic status for a few more decades, but that United States spending powered by public rather than private debt would provide a more sustainable motor for global growth. In the process, the “Bretton Woods II” regime depicted by Dooley, Folkerts-Landau, and Garber (2003) as sustainable despite featuring persistent US current account deficits may turn into a “Bretton Woods III” regime that sees US fiscal policy and public debt as “minding the store” in maintaining US and global growth.
