The US Dollar (USD, symbol $) is the world's primary reserve currency, the most widely traded currency in global foreign exchange markets, and the dominant pricing currency for international commodities including crude oil, gold, and agricultural products. The USD is issued by the US Federal Reserve and serves as the benchmark reference currency for most international trade, financial contracts, and central bank reserves globally. In Indian financial markets, the USD is the most significant foreign currency across all dimensions: the USD/INR exchange rate is the most actively monitored macro variable by investors, businesses, and policymakers; USD/INR currency derivatives (futures and options on NSE, BSE) are the most liquid currency contracts in India; and the overwhelming majority of India's international trade, external debt, and FPI investments are denominated in USD. A strong dollar (rising USD/INR) creates a complex mix of effects for India — it makes imports more expensive (particularly crude oil, edible oils, and electronics), increases the rupee cost of USD-denominated debt servicing, reduces FPI inflows as the dollar becomes more attractive, but simultaneously benefits Indian IT exporters and NRI remittances which are valued in stronger dollars. The RBI intervenes in the USD/INR market using its foreign exchange reserves — buying dollars when the rupee strengthens excessively and selling when the rupee depreciates sharply — to manage volatility without targeting a specific exchange rate level under India's managed float regime.
