RBI Forex Cap Explained: Why Banks Are Worried Amid Rupee Pressure

Why in News ?

• The Reserve Bank of India has directed banks to cap their net foreign currency exposure at $100 million per day to contain the sharp depreciation of the rupee.
• The move comes amid : 
  • Rising crude oil prices due to West Asia geopolitical tensions
  • Persistent inflationary pressures
  • Continuous outflows by Foreign Portfolio Investors (FPIs)
• Despite the measure, the rupee weakened further, breaching ₹94–95 per dollar levels, indicating deeper structural pressures.

Background and Context

• The Indian rupee has been under sustained pressure due to a combination of external shocks and domestic vulnerabilities, particularly :
  • Surge in global crude oil prices (India being a major oil importer)
  • Strengthening of the US dollar globally
  • Capital outflows from emerging markets
• The RBI traditionally intervenes by :
  • Selling dollars from its forex reserves
  • Adjusting liquidity and interest rates
• However, in the current scenario, the RBI has shifted from direct intervention → regulatory intervention, indicating concerns about preserving forex reserves.
• India’s forex reserves have declined by over $30 billion to around $698 billion, reflecting heavy intervention to stabilise the currency.

What is RBI’s Forex Cap and How Does it Work ?

• The RBI has imposed a cap on banks’ Net Open Position (NOP) in foreign currencies, limiting their exposure to $100 million per day.
• Earlier Framework :
  • Banks could hold foreign currency exposure up to 25% of their capital base
  • Allowed flexibility in currency trading and arbitrage
• New Framework :
  • Strict quantitative cap on daily exposure
  • Banks required to unwind excess positions by April 10
• Intended Impact :
  • Forces banks to sell dollars → increases dollar supply in the market
  • Reduces speculative positions against the rupee
  • Stabilises exchange rate volatility in the short term

Drivers of Rupee Depreciation

1. FPI (Foreign Portfolio Investor) Outflows

• FPIs have been net sellers throughout the month, leading to sustained capital outflows.
• Key reasons : 
  • Weak global equity sentiment
  • Depreciating rupee reducing returns
  • Risk aversion due to geopolitical instability

2. Rising Crude Oil Prices

• Oil prices remaining above $100 per barrel increase India’s import bill.
• Leads to : 
  • Higher demand for dollars
  • Widening Current Account Deficit (CAD)
• Directly exerts downward pressure on the rupee.

3. External Sector Vulnerability

• Combination of : 
  • High import dependence
  • Declining remittances (possible Gulf impact)
  • Capital outflows
• Creates stress on India’s Balance of Payments (BoP).

Why Banks Are Worried

• Abrupt Implementation Timeline :
  • Banks have limited time to unwind large forex positions, creating operational and financial stress.
• Risk of Mark-to-Market Losses :
  • Forced selling of dollar assets at unfavourable exchange rates may lead to significant losses (estimated $11–15 billion exposure).
• Impact on Treasury Operations :
  • Reduced scope for currency arbitrage between onshore and offshore markets
  • Loss of an important revenue stream
• Market Distortion Risks :
  • Stricter domestic rules may shift trading to offshore markets (e.g., NDF markets)
  • Could increase speculative pressure on the rupee

Institutional and Policy Approach

• The RBI’s move reflects a strategic shift in policy approach:
• From Direct Intervention :
  • Selling dollars from forex reserves
• To Indirect Regulation :
  • Controlling market behaviour through exposure limits
• Objective :
  • Preserve forex reserves (“war chest”)
  • Reduce volatility without excessive reserve depletion

Lessons from Past Currency Crises

• During crises like :
  • Global Financial Crisis (2008)
  • Taper Tantrum (2013)
• Under Raghuram Rajan, RBI used multiple tools :
  • FCNR(B) Scheme :
    • Attracted over $30 billion in foreign currency deposits
  • Dollar Swap Windows :
    • Provided liquidity to oil companies
  • Monetary Tightening :
    • Increased interest rates to control inflation and boost investor confidence
  • Capital Flow Management :
    • Eased FPI and ECB norms
    • Restricted gold imports to reduce outflows

 Key Concepts Related to Forex

1. Foreign Exchange Reserves

• Comprise : 
  • Foreign currency assets
  • Gold reserves
  • SDRs (Special Drawing Rights)
  • Reserve position in IMF
• Used to : 
  • Stabilise currency
  • Manage external shocks

2. Exchange Rate Regime in India

• India follows a managed floating exchange rate system : 
  • Market determines value
  • RBI intervenes to prevent excessive volatility

3. Net Open Position (NOP)

• Refers to : 
  • Difference between a bank’s foreign currency assets and liabilities
• High NOP : 
  • Increases risk exposure
  • Can amplify currency volatility

4. FCNR(B) Accounts

• Foreign Currency Non-Resident (Bank) deposits : 
  • Maintained in foreign currency
  • Protect NRIs from exchange rate risk

5. Balance of Payments (BoP)

• Comprises : 
  • Current Account (trade, services, remittances)
  • Capital Account (FDI, FPI, loans)
• Deficit → pressure on currency

Challenges and Concerns

• Limited Effectiveness :
  • Forex cap alone may not counter strong macroeconomic pressures
• Market Confidence Issues :
  • Frequent regulatory changes may signal instability
• External Dependence :
  • India’s vulnerability to oil prices and global capital flows persists
• Offshore Speculation Risk :
  • Increased activity in offshore markets may weaken policy impact

Significance

• Economic Stability :
  • Helps manage currency volatility and inflation
• External Sector Management :
  • Protects forex reserves during global uncertainty
• Financial System Discipline :
  • Limits excessive risk-taking by banks
