Swap Operations
Buy-Sell Swap:

NDF Market Monitoring
Non-Deliverable Forward:

Intervention Timing and Strategy
When Does RBI Intervene?
| Trigger | Likely Action |
|---|---|
| Sharp rupee fall | Sell dollars |
| Sharp rupee rise | Buy dollars |
| High volatility | Two-way intervention |
| Speculative pressure | Aggressive counter |
| Thin market | Support stability |
How Much?
Not Disclosed: RBI doesn’t announce intervention amounts real-time
Inferred From:
- Weekly forex reserve changes
- RBI monthly bulletin data
- Market dealer estimates
Typical Range:
- Routine: $500M - $2B per day
- Heavy: $3B - $5B per day
- Crisis: $10B+ per day
Intervention Style
| Style | Description |
|---|---|
| Sterilized | Offset rupee impact via OMO |
| Non-sterilized | Allow rupee liquidity impact |
| Leaning against wind | Counter market direction |
| Leaning with wind | Support market direction |
Sterilization of Intervention
What is Sterilization?
When RBI buys dollars, it injects rupees into economy. Sterilization absorbs this excess liquidity.
Sterilization Methods
| Method | How It Works |
|---|---|
| OMO sale | Sell government securities |
| MSS bonds | Issue Market Stabilization Scheme bonds |
| CRR hike | Increase Cash Reserve Ratio |
| Reverse repo | Absorb through LAF |
Example
| Step | Action | Effect |
|---|---|---|
| 1 | RBI buys $1B at ₹83 | Injects ₹8,300 crore |
| 2 | RBI sells G-secs worth ₹8,300 crore | Absorbs ₹8,300 crore |
| Net | Reserves up, money supply unchanged | Sterilized |
Sterilization Costs
- Interest paid on MSS bonds
- Difference between dollar return and rupee cost
- “Quasi-fiscal” cost to RBI
Forex Reserves Management
Reserve Composition
| Component | Approximate Share |
|---|---|
| Foreign Currency Assets | 90%+ |

Reserve Adequacy
Import Cover: $$Import\ Cover = \frac{Forex\ Reserves}{Monthly\ Imports}$$
India’s Level: ~10-11 months (comfortable)
Other Metrics:
| Metric | India’s Level |
|---|---|
| Reserves/Short-term debt | >3x |
| Reserves/GDP | ~15-20% |
Exchange Rate vs Monetary Policy
Trilemma (Impossible Trinity)
Cannot Have All Three:
- Fixed exchange rate
- Free capital movement
- Independent monetary policy
India’s Choice:
- Flexible (managed) exchange rate ✓
- Relatively free capital flows ✓
- Independent monetary policy ✓
Interest Rate Impact
Higher India Rates:
- Attract foreign capital
- Rupee appreciation pressure
- RBI may buy dollars
- Sterilize to avoid rupee surge
Lower India Rates:
- Capital outflow pressure
- Rupee depreciation pressure
- RBI may sell dollars
- Support rupee
Capital Flow Management
Types of Capital Flows
| Type | Description | Volatility |
|---|---|---|
| FDI | Direct investment | Low |
| FPI | Portfolio investment | High |
| ECB | External commercial borrowing | Medium |
| NRI deposits | Non-resident deposits | Medium |
Regulations Affecting Flows
| Regulation | Impact |
|---|---|
| FPI limits | Sector-wise caps |
| ECB guidelines | Borrowing costs/tenor |
| NRI interest rates | FCNR/NRE rates |
| LRS limits | Individual outflows |
During Crisis
Measures Taken (2013, 2018, etc.):
| Measure | Purpose |
|---|---|
| NRI deposit rate hike | Attract inflows |
| ECB relaxation | Increase dollar supply |
| FPI limits eased | Encourage investment |
| Gold import restrictions | Reduce dollar demand |

Frequently Asked Questions
Q: Does RBI want a weak or strong rupee? A: RBI doesn’t target a specific level. It aims for orderly market conditions and smooth adjustment to fundamentals. Neither extreme appreciation nor depreciation is desired.
Q: How can I know when RBI is intervening? A: Real-time data isn’t available. Watch for: unusual price stability during volatile periods, reserve changes in weekly data, and dealer commentary.
Q: Why doesn’t RBI stop rupee from falling? A: Defending a specific level would deplete reserves quickly. RBI manages the pace of movement, not the direction that fundamentals warrant.
Q: Do RBI interventions always work? A: Short-term, yes—they smooth volatility. Long-term, the exchange rate adjusts to fundamentals. RBI cannot permanently override market forces.
Q: How does RBI intervention affect me as an investor? A: Reduced volatility provides stability for business planning. However, interventions can’t prevent long-term trends. Plan for currency movements in international investments.
The RBI’s exchange rate management is a delicate balancing act—allowing market forces to determine the rupee’s value while preventing disruptive volatility. Understanding this helps you interpret currency movements and RBI actions better.
