The rupee and the dollar: Depreciation, reserves and what moves the rate
Depreciation headlines change every month. The framework behind them does not. Three parts make up that framework.
What moves the rupee. Trade, capital flows and global dollar strength.
How the RBI responds. Intervention that curbs volatility, never targeting a level.
How reserves act. A buffer that absorbs shocks, tracked for solvency and liquidity.
The regime: a managed float
India does not fix the rupee and does not leave it fully free. Under the managed float, the rate is market-determined, but the RBI intervenes to curb excess volatility. It explicitly does not target a level. Intervention works through the spot market.
| Action | Effect |
|---|---|
| RBI buys dollars | Adds rupees; prevents sharp appreciation |
| RBI sells dollars | Absorbs rupees; supports the rupee |

The three forces that move the rupee
Trade. The trade deficit is the starting point. Oil dominates India's import bill, and a wider deficit raises dollar demand.
Capital flows. FPI inflows into equity and debt, plus FDI, supply the dollars that finance the deficit.
Global dollar strength. When the US Federal Reserve holds rates high, the dollar index rises and most emerging-market currencies, including the rupee, weaken against it.
Reserves as the buffer
The RBI publishes reserve data weekly. Reserves have four components.
Foreign currency assets. The largest component, held in major currencies.
Gold. A hedge that diversifies the reserve stock.
Special Drawing Rights. The IMF's reserve asset, allocated to members.
Reserve tranche position. India's readily available quota-based claim at the IMF.
The official framework judges adequacy on two lenses. Solvency compares external debt to GDP. Liquidity compares reserves to short-term debt. A weaker rupee also has a mechanical effect. It raises the rupee value of foreign-currency debt, which is why the currency-debt mix is tracked so closely.
Prelims traps
| Statement | True or False |
|---|---|
| "India follows a fixed exchange rate" | False. Managed float |
| "RBI intervention targets a specific rupee level" | False. It curbs volatility only |
| "SDRs are a component of forex reserves" | True |
| "Rupee depreciation makes imports cheaper" | False. It makes imports costlier |
