Every Friday, the Reserve Bank of India announces a number that makes headlines: India’s foreign exchange reserves, hovering above 600 billion dollars – the world’s fourth or fifth largest stockpile. It is often described as the country’s financial fortress, the buffer that saved India during past crises. But what exactly sits in this vault? Dollars in a vault? Gold bars? And how does the RBI use this mountain of money when the rupee comes under attack? Here is how forex reserves actually work.

What the reserves contain

Forex reserves are external assets readily available to the central bank, and they come in four components. The bulk – roughly 85 per cent – is foreign currency assets: deposits and securities denominated in dollars, euros, yen and pounds, mostly US Treasury bonds and deposits with other central banks. Gold is the second component, around 8 to 10 per cent, held as bars in vaults in Mumbai and abroad; the RBI has been steadily adding gold in recent years as a diversification away from dollar dependence. Then come Special Drawing Rights (SDRs) – the IMF’s reserve asset allocated to member countries – and the reserve tranche position with the IMF, India’s readily available drawing rights. The total is reported in dollars, so valuation changes in gold prices and euro-dollar moves shift the headline number even when nothing is bought or sold.

How reserves are built – and depleted

Reserves grow when dollars flow into India faster than they flow out: foreign investment inflows, a strong export season, or NRI deposits. The RBI often buys these dollars in the market to prevent excessive rupee appreciation, adding to reserves – this “leaning against the wind” is how the stockpile accumulated over two decades. Reserves shrink in the reverse situation: when the RBI sells dollars to support a falling rupee, or when valuation losses hit. The RBI’s stated policy is not to target any exchange rate level but to curb excessive volatility – which in practice means buying dollars when inflows surge and selling when outflows panic. Every dollar sold defending the rupee is a dollar subtracted from the reserves, which is why sustained intervention shows up as falling reserve numbers.

Why reserves matter: the three jobs

• Crisis buffer: reserves let India pay for imports and service debt even if foreign capital flees – the lesson of 1991, when reserves covered barely three weeks of imports.
• Currency stabilisation: the RBI’s dollar sales smooth sharp rupee falls, preventing panic-driven overshooting that would spike inflation.
• Confidence signal: large reserves reassure foreign investors and rating agencies that India can meet its external obligations – the import cover ratio (reserves divided by monthly imports, currently around 11 months) is the classic adequacy metric.

Economists also track reserves against short-term external debt – the Guidotti-Greenspan rule says reserves should cover all debt maturing within a year, a test India passes comfortably. These metrics are why 600 billion dollars is described as comfortable: it covers multiple stress scenarios at once.

The costs and limits of the fortress

Holding reserves is not free. The RBI earns low yields on safe foreign assets – US Treasuries at 4 per cent – while the dollars it absorbed were issued against rupees that could otherwise have funded domestic investment; economists call this the sterilisation cost. There is also concentration risk: heavy dollar holdings mean American monetary policy moves India’s reserve valuations. And reserves have limits as a defence – no stockpile can hold the rupee at an unsustainable level forever, as the RBI itself acknowledges; intervention buys time and smooths volatility, it does not repeal economics. The fortress is real, but it is a shock absorber, not a wall.

FAQs

Does the RBI’s gold belong to the government?

The gold is on the RBI’s balance sheet as part of reserves. The central bank manages it independently, though large movements are coordinated with the government’s broader economic stance.

Why did reserves fall sharply in 2022?

A combination of RBI dollar sales to defend the rupee during the oil shock and valuation losses as the dollar strengthened against the euro and gold prices moved – not a single cause.

Can reserves be used to fund government spending?

No. Reserves are the RBI’s assets backing external stability, not a fiscal piggy bank. Transfers to the government happen only through the RBI’s surplus (dividend) mechanism, not from reserves themselves.
