Resumen:
This paper shows how global dollar appreciations transmit to emerging market and developing economies (EMDEs) through commodity prices and country risk. Using quarterly data for 22 EMDEs from 1999–2019, I combine the Obstfeld & Zhou (2023) dataset with country-specific commodity price indices and classify countries as commodity exporters or importers via a trade-balance rule. Global dollar appreciation shocks explain up to 16% of the forecast-error variance of commodity terms of trade (CToT) and up to 9% of EMBI spreads. A global dollar appreciation depreciates EMDE currencies, raises EMBI, depresses investment, and lowers GDP, with muted CPI effects. Stratifying by commodity status reveals sharp heterogeneity: exporters suffer larger and more persistent adverse responses, while importers seem stable. To uncover mechanisms, I implement an approach `a la Cloyne–Jord`a–Taylor (2023) to estimate indirect effects. A more favorable CToT response mitigates output and demand contractions, whereas higher commodity import prices and larger EMBI responses amplify adverse outcomes.
