Exchange Rate Determination and India's Managed Float
The Indian rupee operates under a managed float (or "dirty float") system, where the Reserve Bank of India (RBI) intervenes in the foreign exchange market to prevent excessive volatility, while the exchange rate is broadly determined by market forces of supply and demand. India moved from a fixed exchange rate to a market-determined system in 1993 as part of liberalisation reforms.
- RBI intervenes through buying/selling of dollars in the spot and forward markets
- Current Account Deficit (CAD) is the primary structural driver of rupee weakness — India imports more than it exports, creating dollar demand
- Foreign Portfolio Investment (FPI) flows are a secondary driver — when FPIs sell Indian equities, they convert rupees to dollars, weakening the currency
- India's foreign exchange reserves act as a buffer; as of early 2026, reserves stood above $600 billion
Connection to this news: The US blockade announcement triggered FPI outflows from Indian equities, simultaneously increasing dollar demand (as investors converted proceeds) and reducing supply, creating a double-pressure on the rupee.
India's Energy Import Dependence and Currency Vulnerability
India imports approximately 85–87% of its crude oil requirements, making it the world's third-largest oil consumer and importer. Rising global crude prices directly widen India's import bill, increasing demand for foreign exchange (predominantly US dollars) and pressuring the current account.
- Every $10 per barrel increase in crude prices widens India's CAD by approximately 0.4–0.5% of GDP
- India's oil import bill constitutes roughly 25–30% of total merchandise imports
- The rupee and crude oil prices have a historically inverse relationship — as Brent rises, INR typically weakens
- India has diversified crude sources to 41 countries as of 2026, reducing but not eliminating Hormuz vulnerability
Connection to this news: The Hormuz blockade threat pushed crude prices higher, directly raising India's oil import bill expectations and reinforcing bearish sentiment on the rupee.
Foreign Portfolio Investment (FPI) Dynamics
Foreign Portfolio Investors (FPIs) hold a significant share of Indian equity markets and government securities. FPI flows are highly sensitive to global risk appetite, geopolitical shocks, and differential interest rate expectations between India and advanced economies.
- FPI outflows create selling pressure on both equities and the rupee simultaneously
- SEBI regulates FPI registration; the RBI monitors aggregate FPI limits in government bonds
- Geopolitical events — especially those affecting oil prices and global growth — trigger risk-off behaviour, causing FPI exits from emerging markets including India
- India's inclusion in global bond indices (JP Morgan GBI-EM, Bloomberg EM index) since 2024–25 has deepened FPI participation in debt markets
Connection to this news: West Asia uncertainty caused FPIs to exit Indian equities, amplifying both the stock market fall and the rupee's depreciation in a feedback loop.
