How RBI Defends the Indian Rupee

Why in News?

The Indian Rupee (INR) faced severe depreciation, nearing a historic low of 97 against the US Dollar in May 2026. The RBI deployed a multi-pronged intervention strategy including:

• Daily dollar sales of approximately USD 1 billion in the spot market
• Announcement of a USD 5 billion USD/INR buy-sell swap auction

RBI's Currency Intervention Tools

1. Spot Market Dollar Sales

• First line of defense for the RBI
• Directly sells US Dollars from Foreign Exchange Reserves into the spot market
• Injects immediate dollar supply to match excess demand from importers
• Arrests the rupee's free fall

2. Sterilized Interventions

When RBI sells dollars (draining rupees from the system), it conducts "Sterilized Interventions":

• Open Market Operations (OMOs): Purchasing government bonds to pump rupees back
• Market Stabilisation Scheme (MSS) Bonds: During capital inflows, RBI issues short-dated securities to mop up surplus rupees and prevent inflation

3. Forex Swap Auctions

Used to manage currency and domestic liquidity simultaneously without permanently altering forex reserves:

May 2026: RBI announced USD 5 billion buy-sell swap auction as rupee neared 95 against USD due to US-Iran conflict.

4. Contractionary Monetary Policy

Repo Rate Hikes

• Monetary Policy Committee (MPC) hikes benchmark Repo Rate
• Improves yield differential with US Federal Reserve
• Makes Indian debt attractive to foreign investors
• Encourages capital inflows and supports rupee

Liquidity Adjustment Facility (LAF) Squeeze

• Tightens the LAF corridor, restricting banks' borrowing windows
• Pushes up overnight call money rate
• Makes speculative rupee shorting prohibitively expensive
• Forces speculators to abandon positions

5. Pre-Market & NDF Interventions

Breaking the Speculative Loop

• Heavy dollar sales through state-run banks before onshore market opens
• Forces rupee to open stronger
• Breaks psychological negative feedback loop for traders

Curbing Offshore Market (NDF)

• Speculators often short rupee in offshore Non-Deliverable Forward (NDF) markets (London, Singapore)
• RBI restricts domestic banks' net open forex positions
• Occasionally intervenes directly in NDF market

6. Special Dollar Window for OMCs

• Oil Marketing Companies (OMCs) are largest USD buyers in India
• Daily dollar purchases for crude oil imports create massive demand
• RBI opens dedicated foreign currency credit line for OMCs
• OMCs buy dollars from RBI/SBI at fixed swap rate instead of open market
• Used effectively during 2013 currency crisis

7. Capital Flow Management Measures (CFMs)

Easing Norms

• Temporarily relaxes External Commercial Borrowings (ECB) rules
• Eases caps on Foreign Portfolio Investors (FPIs) in Indian government bonds

Promoting Masala Bonds

• Rupee-denominated bonds issued in overseas markets
• Foreign investor bears currency depreciation risk, not Indian borrower
• Brings foreign capital without creating dollar repayment pressure

Capping Speculative Exposure

• In 2026: Capped banks' Net Open Position (NOP) at USD 100 million per day
• Forced banks to unwind excess dollar holdings
• Increased dollar supply and reduced speculative pressure

8. Mobilizing NRI Capital (Crisis Tools)
