Carry trade profitability in emerging markets depends on a mix of macroeconomic differentials, market structure, and behavioral forces. Empirical research by Markus Brunnermeier of Princeton University, Stefan Nagel of the University of Chicago Booth School of Business, and Lasse Heje Pedersen of New York University Stern shows that carry trades earn returns from persistent interest rate differentials but remain exposed to abrupt losses when adverse shocks trigger currency repricing. Hyun Song Shin of Princeton University and the Bank for International Settlements emphasizes that global funding conditions and dollar liquidity also shape these outcomes.
Core economic drivers
The primary determinant is the interest rate differential between the funding currency and the target emerging-market currency: higher differentials create the basic profit motive. Exchange rate expectations and realized exchange rate volatility determine whether those interest gains are wiped out. Short-term funding costs and the ease of borrowing in global markets matter, because carry trades are typically financed with short maturities; when funding tightens, positions are closed quickly and exchange rates move sharply. Central bank credibility and monetary policy frameworks influence both the differential and volatility, while the depth of local bond and FX markets affects transaction costs and execution risk.
Risks, consequences, and local nuances
Political instability, weaker institutions, and limits on capital mobility raise country risk and can convert steady carry returns into losses through sudden stops or devaluations. Commodity dependence links currency performance to environmental and territorial factors: droughts, floods, or global commodity price swings can rapidly alter terms of trade and currency value for exporters. Cultural and social consequences are tangible—currency crashes often drive inflation, erode real wages, and increase poverty in vulnerable communities. Liquidity constraints and domestic banking sector strength determine how much markets can absorb unwinding positions without systemic spillovers.
Policy responses influence profitability and broader effects. Capital controls, foreign reserve buffers, and macroprudential measures change incentives and can dampen short-term flows. Research highlights by Brunnermeier, Nagel, and Pedersen indicate that carry returns compensate investors for rare but severe crash risk, while analysis by Hyun Song Shin links global liquidity cycles to the frequency of those crashes. For practitioners and policymakers in emerging markets, understanding leverage and funding liquidity, alongside domestic institutional strength and environmental exposures, is essential to assessing whether carry trades will be profitable or destabilizing.
