RBI Net Forex Buys Reach Record $43.26 Billion in August as Swaps Offset Inflow Impact

The Reserve Bank of India (RBI) recorded its highest-ever monthly net dollar purchase of $43.264 billion in the spot foreign exchange market in August, according to official data released in the central bank's monthly bulletin. The record buying was more than double the net purchase of $18.652 billion in July, driven primarily by dollars mobilized under concessional swap facilities.

During the month, gross dollar purchases by the central bank climbed to $74.472 billion, while spot dollar sales stood at $31.208 billion across onshore and offshore over-the-counter segments.

Inflows From Concessional Windows

The steep uptick in spot purchases coincided with the culmination of the RBI's special foreign exchange swap facilities for Non-Resident Indian (NRI) deposits and overseas commercial borrowings.

Key drivers behind the record intervention include:

• FCNR(B) Inflow Absorption: Commercial banks channeled foreign currency raised under the concessional Foreign Currency Non-Resident (Bank) deposit window directly to the central bank.
• Window Closure: The central bank brought forward the closure of the concessional mobilization window to August 31 after banks garnered substantial sums, prompting lenders to surrender accumulated dollar liquidity.
• Cumulative Purchases: Between end-March and end-August, the RBI’s cumulative net dollar purchases stood at $47.430 billion (equivalent to ₹4,56,981 crore), reversing the aggressive net selling witnessed across FY26.

Balancing via the Forward Market

Had the RBI simply absorbed $43.264 billion in the spot market without counter-measures, it would have injected massive rupee liquidity into the banking system, potentially stoking inflation and dragging short-term money market rates below the policy repo corridor.

To prevent domestic liquidity distortions, the RBI simultaneously conducted large-scale sell/buy swaps in the foreign exchange market. In these transactions, the central bank bought dollars in the spot market and simultaneously contracted to sell them back at a future date.

As a consequence of this strategy, the RBI's outstanding net short position in the forward dollar book surged by $63.29 billion in a single month, reaching an unprecedented $200.06 billion at the end of August, up from $136.77 billion recorded at the end of July.

Implications for Rupee and Indian Markets

The heavy intervention reflects the central bank’s two-way operations to moderate exchange rate volatility amid fluctuating crude oil prices, a resilient US dollar, and shifting foreign portfolio flows.

While absorbing inflows helped build external buffers and anchored foreign exchange reserves, the RBI deployed spot sales whenever the rupee faced depreciation pressure from elevated crude import bills.

For participants in Indian financial markets, the central bank’s forward book management signals that domestic liquidity conditions will remain closely calibrated. By effectively sterilizing the massive influx of foreign capital through forward contracts, the RBI has insulated bond yields from sudden structural swings while ensuring the rupee remains competitive and relatively stable against peers.
