Geopolitical Risks and Currency Volatility: The U.S.-Russia Tensions' Impact on Emerging Markets

The U.S.-Russia geopolitical tensions since 2022 have become a defining force in shaping emerging market currency volatility. As the Russia-Ukraine war persists and sanctions reshape global trade dynamics, the ripple effects on financial markets are profound. Emerging economies, particularly those with exposure to energy and trade flows, face heightened uncertainty, with currencies like the Turkish lira, Indian rupee, and South African rand exhibiting pronounced swings. This analysis examines how geopolitical risks, compounded by U.S. monetary policy and digital currency innovations, are redefining the landscape for investors.

The Dollar's Resilience Amid Shifting Tides

The U.S. dollar remains the cornerstone of global finance, accounting for 58% of official foreign exchange reserves as of 2025, according to the Federal ReserveThe International Role of the U.S. Dollar – 2025 Edition^[1]. Despite challenges such as Trump-era tariffs and the rise of central bank digital currencies (CBDCs), the dollar's dominance in trade invoicing (96% in the Americas, 74% in Asia-Pacific) underscores its entrenched roleThe International Role of the U.S. Dollar – 2025 Edition^[1].

Currency Volatility in Emerging Markets: Case Studies

Turkish Lira (TRY):
The TRY has been a bellwether of geopolitical risk. Between March and September 2025, the TRY/INR exchange rate fell from 2.2722 to 2.1243, a 6.5% declineTurkish Lira (TRY) to Indian Rupee (INR) Historical Exchange Rates^[5]. This volatility stems from Turkey's dual exposure: as a NATO ally, it faces U.S. pressure to align with sanctions, yet its economy relies heavily on Russian energy and trade. The Central Bank of Turkey's 50% interest rate hike in 2024 failed to curb depreciation, as global risk aversion and sanctions-driven capital outflows persistedTurkish Lira to Indian Rupees Exchange Rate History - Wise^[6].

Indian Rupee (INR):
India's currency has faced indirect pressures from U.S.-Russia tensions. By 2025, India accounted for 25% of Russia's oil exports, a shift driven by its refusal to join Western sanctionsThe Impact of Sanctions on Russia’s Economy: A 2025 Perspective^[7]. While this provided cheaper energy, it also exposed the rupee to geopolitical risks. The INR depreciated 4% against the dollar in 2025, partly due to Trump's threats of tariffs on Russian oil importsGeopolitical Tensions 2025: Market Risks and Insights^[8].

Conclusion

The U.S.-Russia tensions have not only amplified currency volatility in emerging markets but also accelerated the reconfiguration of global trade and financial systems. While the dollar's dominance persists, the rise of CBDCs, gold, and regional trade blocs signals a multipolar future. Investors must navigate this landscape with agility, balancing exposure to high-risk emerging markets with hedging strategies that account for geopolitical shocks. As the August 2025 summit demonstrated, even incremental diplomatic progress can trigger market revaluations, underscoring the need for continuous monitoring of geopolitical developments.
