Causes, Impact and the Role of RBI
Why This Topic Matters?
Open any newspaper in 2024–25 and you will find headlines like “Rupee hits a new low” or “RBI intervenes to stabilise the rupee.” For a UPSC aspirant, this is not just news — it is GS Paper 3 (Economy), Essay material, and a favourite Prelims topic all rolled into one. This guide breaks the concept into bite-sized pieces, each illustrated with a real-world example or a relatable analogy.
| Analogy Think of the rupee as a school cricket team and the dollar as the international team it plays against. When our players keep losing wickets (oil bills, FII exits, weak exports), the scoreboard (exchange rate) tilts in the dollar’s favour. RBI is the coach — it cannot bat for the team, but it can change strategy, rotate bowlers (reserves), and call timeouts (interventions). |
1. What Is Rupee Depreciation?
Rupee depreciation simply means the Indian rupee is buying fewer dollars than before. If yesterday you needed ₹80 to buy 1 USD and today you need ₹90, the rupee has weakened (depreciated) and the dollar has strengthened (appreciated).
| Example In January 2008, 1 USD ≈ ₹39. In 2013 (taper tantrum) it crossed ₹68. By 2022 it touched ₹83, and in early 2025 it briefly went past ₹87. Over 17 years, the rupee has more than halved against the dollar — a textbook long-term depreciation. |
| Analogy Imagine you are buying mangoes at a wedding-season market. Last week one box cost ₹100. This week the same box costs ₹120 because mangoes are scarce. The mango did not become “better” — your money simply lost purchasing power for that mango. Replace “mango” with “dollar” and you understand depreciation. |
2. Causes of Rupee Depreciation
The rupee’s fall is rarely due to a single villain. Several forces act together. Let’s unpack each one.
Rising Crude Oil Prices
India imports roughly 85% of its crude oil needs. Oil is priced in dollars globally. When crude prices climb, our oil import bill swells, which means oil companies need more dollars — pushing up demand for the dollar and weakening the rupee.
| Example During the Russia–Ukraine war in 2022, Brent crude shot past USD 120/barrel. India’s monthly oil import bill jumped from about USD 10 billion to nearly USD 20 billion. The rupee slid from ₹76 to ₹83 in the same period. |
| Analogy If your household depends on cylinder gas and the cylinder price doubles, your monthly budget gets squeezed. India is that household — and crude oil is the cylinder. |
A Strengthening US Dollar
When the US Federal Reserve raises interest rates or when the global economy looks shaky, investors worldwide rush to park their money in US assets (bonds, dollars) because they are seen as safe. This is called a “safe-haven flow.” As the dollar becomes globally stronger, the rupee — like most emerging-market currencies — looks weaker by comparison.
| Example In 2022, the US Fed raised rates seven times. The Dollar Index (DXY) rose to a 20-year high of 114. During the same period, almost every Asian currency — yen, won, rupee, baht — fell sharply. |
| Analogy If the strongest student in class suddenly starts scoring even higher, everyone else’s relative rank falls — not because they did worse, but because the topper raised the bar. |
Foreign Portfolio (FPI/FII) Outflows
Foreign Institutional Investors bring dollars into India to buy our stocks and bonds. When they sell and exit, they take those dollars back home. Heavy outflows reduce dollar supply in India — and the rupee weakens.
| Example In FY 2021–22, FIIs pulled out a net of about USD 14 billion from Indian equities — the largest annual outflow on record at that time. The rupee crossed ₹80 for the first time soon after. |
| Analogy A wedding hall (Indian markets) is full of guests who came with gift packets (dollars). If many guests suddenly walk out with their packets, the host has fewer resources to spend — that is exactly what FII outflows do to our forex pool. |
Global Risk-Off Sentiment
“Risk-off” is jargon for “investors are scared.” Wars, banking crises, pandemics, election uncertainty — all trigger a flight from emerging markets to safer assets like US treasuries, gold, and the Swiss franc.
| Example During COVID-19’s first wave in March 2020, the rupee fell from ₹71 to ₹76 within three weeks even though India’s fundamentals had not changed overnight. It was pure global panic. |
| Analogy In a thunderstorm, everyone runs from the open ground to the strongest building. The dollar is that strongest building during global storms. |
Interest Rate Differentials
Money moves to where it earns more, after adjusting for risk. If US interest rates rise faster than Indian rates, the gap (“differential”) narrows. Investors find dollar deposits more attractive and shift money out of India.
| Example In 2022–23, the US Fed rate climbed from 0.25% to 5.5%. India’s repo rate rose from 4% to only 6.5%. The narrowed gap reduced the rupee’s relative appeal. |
| Analogy Two banks across the road from each other. If one suddenly offers 8% interest on FDs while the other still offers 6%, customers will queue up at the first. That “queue” is the dollar inflow into the US. |
Trade Deficit and Current Account Deficit (CAD)
A trade deficit means India imports more goods than it exports. The current account deficit is broader — it includes trade plus services, remittances, and income flows. A persistent CAD means India is a net buyer of dollars, which structurally pressures the rupee.
| Example India’s CAD widened to 4.4% of GDP in Q2 FY 2022–23, the highest in nearly a decade, mainly because of expensive oil and electronics imports. The rupee predictably weakened. |
| Analogy A family that spends more than it earns every month must keep borrowing or selling assets. The country does the same with dollars — and the “price” of those dollars (the exchange rate) keeps rising. |
| UPSC Tip Memory trick — the acronym “COFIRT”: Crude oil, Outflows (FII), Fed/dollar strength, Interest-rate gap, Risk-off, Trade deficit. Six causes, one word. |
3. Impact of Rupee Depreciation on the Indian Economy
Depreciation is not all bad news. It is a double-edged sword — it cuts the import side but helps the export side. UPSC essays often expect you to argue both directions.
The Positive Side
- Exports become more competitive: A weaker rupee makes Indian goods cheaper for foreign buyers. A US importer who paid ₹80 for 1 USD now gets ₹90 worth of Indian goods for the same dollar.
- Boost to IT, pharma, textiles, gems & jewellery: These sectors earn in dollars and report higher rupee revenues.
- Higher remittances in rupee terms: NRIs sending money home see their dollars convert into more rupees.
| Example In FY 2022–23, India’s services exports — led by IT — crossed USD 320 billion, an all-time high. A part of this strong showing came from a weaker rupee boosting rupee-denominated revenues. |
| Analogy Imagine you run a small handicraft shop and tourists are your customers. If the local currency weakens, your products feel like a bargain to tourists — and your sales go up. |
The Negative Side
- Costlier imports: Oil, gold, electronics, edible oil, fertilisers — all become more expensive in rupee terms.
- Imported inflation: Higher import prices feed into domestic prices, raising the CPI basket.
- Higher external debt servicing: Indian companies that borrowed in dollars now need more rupees to repay the same loan.
- Costlier foreign education and travel: Students studying abroad and overseas tourists feel the pinch.
- Pressure on growth: Higher input costs and inflation can force the RBI to tighten rates, slowing investment.
| Example In 2022, India’s edible oil imports (sunflower, palm) became significantly costlier due to both Ukraine-war supply shock and rupee weakness — household food bills rose noticeably. |
| Analogy A weak rupee is like cheap petrol that comes with a leaking tank. Yes, the export side gains, but the import side loses more — and the household feels the loss faster than the gain. |
4. The Role of the Reserve Bank of India
India follows a “managed float” exchange-rate system. That means the rupee is mostly market-determined, but the RBI steps in when volatility becomes excessive. The aim is not to fix the rupee at a target level, but to smooth the ride.
Forex Reserves — The Shock Absorber
India’s foreign exchange reserves crossed USD 700 billion in 2024, among the largest in the world. When the rupee falls too fast, the RBI sells dollars from these reserves, increasing dollar supply and supporting the rupee.
| Analogy Forex reserves are like the country’s water tank on the rooftop. When the supply line (dollar inflows) is weak, you open the tap from the tank to keep the household running. |
Monetary Policy Tools
By raising the repo rate, the RBI makes rupee deposits more attractive and discourages capital outflows. It can also tweak the Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) to manage banking-system liquidity.
Direct Intervention in Forex Markets
The RBI operates in the spot, forward, and NDF (non-deliverable forward) markets — sometimes openly, sometimes through public-sector banks. Its actions can be:
- Selling dollars to defend the rupee when it weakens sharply.
- Buying dollars to prevent the rupee from appreciating too much (which would hurt exporters).
- Swap operations with banks to manage short-term liquidity in dollars.
Macroprudential and Capital-Flow Measures
The RBI can raise interest-rate ceilings on NRI deposits (FCNR-B), ease External Commercial Borrowing (ECB) limits, or allow special swap windows — all aimed at bringing more dollars into India during stress periods.
| Example In 2013, when the rupee crashed during the “taper tantrum,” RBI Governor Raghuram Rajan launched a special FCNR-B swap window that mobilised about USD 34 billion in three months — one of the most successful currency-defence operations in Indian history. |
| Analogy If your boat is rocking violently, you do not try to stop the sea — you adjust the sail. RBI does not target a rupee number; it adjusts the sail so the boat stays steady. |
5. Depreciation vs. Devaluation — Don’t Confuse the Two
| Aspect | Depreciation | Devaluation |
| Exchange-rate system | Floating (market-driven) | Fixed or pegged |
| Who decides | Market forces of demand & supply | Government or central bank |
| Nature | Gradual, ongoing | Sudden, deliberate, official |
| Indian example | Rupee fall from ₹80 to ₹83 in 2022 | 1966 (₹4.76 → ₹7.50) and 1991 (twice in three days) |
| Used in current India? | Yes — this is the regular phenomenon | Rarely; India is now a managed float |
| Analogy Depreciation is like a stone slowly rolling downhill — gravity does the work. Devaluation is like someone deliberately kicking the stone down. Both end up at the bottom, but one is natural, the other is intentional. |
| Example India’s 1991 devaluation: Faced with a balance-of-payments crisis, the RBI devalued the rupee in two steps on July 1 and July 3, 1991, by a total of about 18–19%. This was a conscious policy choice — pure devaluation, not depreciation. |
6. Why Is the Rupee Depreciating Right Now?
Recent pressure on the rupee is the result of a familiar mix of global and domestic factors:
- Strong US dollar, with the Fed keeping rates higher for longer.
- Geopolitical tensions (West Asia, Russia–Ukraine) keeping crude oil volatile.
- FPI outflows from emerging-market equities during global risk-off phases.
- A widening goods-trade deficit, especially with China.
- Election-cycle uncertainty in major economies affecting investor sentiment.
| UPSC Tip In the Mains answer, always close with a balanced note: “A weaker rupee is not automatically bad — what matters is volatility. The RBI’s stated goal is to manage volatility, not the level of the rupee.” |
7. Quick Revision: One-Line Takeaways
- Depreciation = market-driven fall; Devaluation = official decision.
- Six causes — Crude, Outflows, Fed/dollar, Interest gap, Risk-off, Trade deficit (COFIRT).
- Positives: exports, IT, remittances. Negatives: imports, inflation, external debt.
- RBI uses reserves, repo rate, forex intervention, and capital-flow measures.
- India follows a managed float; RBI targets volatility, not a specific exchange rate.
- Forex reserves above USD 700 billion give India a strong cushion in 2024–25.
