Barry Eichengreen

Barry Eichengreen is the American economist and economic historian, at the University of California, Berkeley, whose histories of reserve currencies define the structural terms of the dollar-weaponisation debate: how international monies rise, why they fall, and how much abuse an incumbent can absorb. When the field asks whether sanctions will cost the dollar its throne, it argues with Eichengreen's evidence.

The work

Golden Fetters (1992) established him as the historian of monetary systems under stress, showing how the interwar gold standard transmitted and deepened the Depression and why loyalty to a monetary orthodoxy can become strategically ruinous. Exorbitant Privilege (2011), taking its title from the French complaint about dollar primacy, analysed the sources of the dollar's advantages, scale, liquidity, credible institutions, and network effects, and the conditions of their erosion. Its central historical corrective, developed further in How Global Currencies Work (2017, with Arnaud Mehl and Livia Chitu), is that reserve-currency incumbency is less winner-take-all than assumed: several international currencies have coexisted before and can again, and sterling's displacement by the dollar happened faster than the old story allowed. Decline, when it comes, is driven mainly by the incumbent's own mismanagement rather than by challengers.

Significance

Eichengreen's framework disciplines the de-dollarisation debate: alternatives to the dollar are structurally possible, but no current challenger offers comparable scale, openness, and legal credibility, so backlash shows up as gradual diversification, including central bank gold accumulation, rather than displacement. The corollary cuts both ways and is contested: incumbency buys room for financial warfare, yet the privilege is self-liquidating if abused, since the credibility that underpins exorbitant privilege is precisely what weaponisation spends. His interwar work also underlies the field's understanding of monetary systems as conflict terrain, background to Currency warfare and the Bretton Woods and Nixon shock entries.
