Key Takeaways
- • Dollar risk transmission extends beyond direct foreign-currency borrowers to domestic firms with no dollar debt, traveling through supplier-financed trade credit relationships in corporate supply chains.
- • Large upstream firms that borrow cheaply in dollars and extend trade credit to domestic customers function as intermediaries between global dollar funding markets and local economies, creating indirect currency exposure downstream.
- • Exchange-rate shocks affect firms indirectly through their financing relationships with suppliers, meaning currency risk allocation across firms depends on balance-sheet strength, contractual flexibility, and supply-chain structure rather than debt composition alone.
- • Trade credit represents a material source of corporate financing—not a marginal balance-sheet item—making firm-to-firm financial linkages a critical channel for macroeconomic risk transmission in emerging markets.
Summary
Research published in the Journal of Financial Economics by Hardie, Saffy, and Simonovska (2026) identifies a previously underappreciated transmission mechanism through which US dollar strength affects emerging-market economies. The study demonstrates that currency risk travels through corporate supply chains and trade relationships, reaching firms that maintain no direct foreign-currency liabilities and do not participate in international trade.
The mechanism operates through trade credit extended by large upstream firms to domestic customers. These suppliers often access dollar funding at favorable rates in global capital markets, then finance their domestic buyers through accounts receivable. This structural arrangement effectively transforms non-financial corporations into financial intermediaries, channeling dollar-denominated funding risks into local supply chains. The result is indirect currency exposure for downstream firms that would otherwise appear insulated from exchange-rate shocks based on their balance sheets alone.
The paper's central contribution reframes how market participants should assess currency risk concentration. Rather than viewing dollar risk as a function solely of a firm's own debt structure or export exposure, the research reveals that risk allocation depends on three interconnected factors: the balance-sheet strength of financing counterparties, contractual flexibility within supplier-customer arrangements, and the overall architecture of financial relationships throughout the supply chain. This finding has material implications for emerging-market credit analysis, as it suggests that traditional metrics focused on a single firm's liability composition may significantly underestimate true currency risk exposure.
Trade credit itself emerges as a substantive financing mechanism in the research, challenging the perception of accounts receivable as a marginal accounting line item. Its prominence as a source of corporate finance means that understanding firm-to-firm financial linkages is essential for grasping how macroeconomic shocks—particularly exchange-rate movements—propagate through developing economies and corporate sectors.
