The Trade Costs of Sovereign Default Reconsidered

Abstract

Trade falls sharply after sovereign default, by roughly eight percent a year between a defaulter and its creditors, persisting for about fifteen years. That finding has been read in two incompatible ways. On the punishment reading, creditors and their governments retaliate, and the anticipated loss of trade is part of what makes sovereign debt enforceable in the absence of collateral or courts. On the disruption reading, nothing is being enforced: trade credit evaporates, banks holding defaulted paper contract lending, importers lose access to inputs, and the trade decline is a symptom of a broken financial circuit rather than a sanction. This article reviews the evidence and argues that the disruption reading now commands most of it. Direct trade sanctions are essentially undocumented; the decline concentrates in sectors dependent on external finance and on imported inputs; and the mechanism that reproduces the observed output and trade dynamics in general equilibrium runs through working capital for imported inputs rather than through retaliation. Three consequences follow, and none is minor. First, the enforcement theory of sovereign debt loses one of its principal candidate mechanisms, which matters because the alternatives have known weaknesses. Second, the trade cost of default becomes a remediable friction rather than an equilibrium feature, which changes what restructuring architecture and trade finance backstops can be expected to achieve. Third, the rhetorical use of trade costs in debt negotiations, where the prospect of trade collapse is deployed as an argument for repayment, rests on a mechanism the evidence does not support, and is better understood as an argument for crisis financing. The article specifies the tests that would settle the remaining ambiguity and identifies where the data fall short.
