Reserve Currency

The world's default money

A reserve currency is the money that central banks around the world choose to stockpile as foreign-exchange reserves, and that traders default to when settling cross-border deals. The US dollar is the undisputed leader: it accounts for roughly 57-58% of global FX reserves, a majority of export invoicing, and the lion's share of foreign-exchange transactions. Behind it sit the euro, the Japanese yen and the British pound.

Reserve status is a privilege economists call an "exorbitant privilege." Because the world wants dollars, the US borrows cheaply and trades in its own currency without exchange-rate risk. Everyone else, including India, must first earn or buy dollars to pay for imports like crude oil.

Why India holds a war chest

The RBI keeps a vast reserve buffer — reported above $680 billion in 2026 — largely in dollar assets, supplemented by gold and other currencies. These reserves are India's shock absorber. When the rupee slid toward the ₹95 area against the dollar amid FPI outflows and oil pressure, the RBI drew on this stockpile to intervene and even capped banks' dollar positions to steady the currency.

This is the everyday cost of *not* issuing a reserve currency: India must hold expensive insurance in someone else's money to defend its own.

The slow push for the rupee

India has been nudging toward internationalising the rupee — settling some trade in rupees, signing local-currency arrangements, and reducing dependence on the dollar for both invoicing and sanctions resilience. The dollar's global share has drifted modestly lower over the years, with the slack spread across several currencies rather than captured by any single rival.

But the rupee remains far from reserve status. Its 2026 volatility and the RBI's frequent interventions underline a structural problem: global counterparties want a currency that is stable, fully convertible and deeply traded, and the rupee is not yet all three. For an Indian investor, the takeaway is sobering — until that changes, dollar moves will keep transmitting straight into import bills, inflation and the value of every overseas fund in your portfolio. The world still runs on dollars, and India must plan around that fact.
