Credit constraints, currency depreciation and international trade

•We document an exporters’ heterogeneous responses to home currency depreciation.•Firms export less in financially vulnerable sectors when home currency depreciates.•With RMB depreciation, firms export 23% less in sectors with more financing needs.•The expansionary effects from RMB depreciation are reduced due to credit constraints. We document multi-sector exporters’ heterogeneous responses to home currency depreciation. Following currency depreciation, firms tend to export relatively less in sectors that depend more on external financing, to avoid adverse impacts of potentially binding credit constraints. More specifically, credit-constrained exporters respond to currency depreciation by increasing production first in sectors with less external financing dependence, then in sectors that are more dependent on outside funds, until they exhaust their limited financial resources. These findings are consistent with our prior that exporters’ needs for external financing are greater when their home currencies depreciate. Upon home currency depreciation, exporters react by expanding production or by entering new destination markets, incurring significant upfront costs. The results survive a series of robustness checks, and are stronger for low-performance firms and for firms engaged in ordinary trade. The results have important policy implications for emerging market countries that rely heavily on exports but have weak financial institutions.
