The Reserve Bank of India (RBI) is reportedly busy conducting sell-buy swaps for the US Dollar-Indian Rupee (USD/INR) pair. According to market sources, the central bank is targeting maturities in September and possibly October. In a sell-buy swap, the RBI sells dollars now to take rupees out of the system and agrees to buy those dollars back later. This acts as a temporary way to reduce the amount of extra money floating in the economy.

This move comes because Indian banks are currently flooded with rupee liquidity (excess cash held by banks). A major reason for this surplus is the huge amount of money coming in from Non-Resident Indians (NRIs). Lenders have raised nearly $128 billion through these overseas deposits. When banks bring these dollars to India, they swap them for rupees, which has pushed the total liquidity surplus to an estimated ₹14 trillion to ₹15 trillion.

Traders and treasury officials noted that the RBI turned to these swaps after other tools did not work as well as expected. Earlier this week, a 30-day Variable Rate Reverse Repo (VRRR) — a tool where the RBI borrows money from banks to suck out liquidity — saw a very weak response from lenders. By using FX (Foreign Exchange) swaps instead, the RBI can manage the cash overhang more effectively for a few weeks at a time.

Bankers estimate that the RBI has already conducted swaps worth about $700 million across the September and October dates. This action has a direct impact on the 'forward premium' (the extra cost to buy currency at a future date). Because the RBI is selling dollars now and buying them back later, the demand for future dollars has gone up. This caused the September forward premium to rise to 10.75 paise, with rates moving higher for other time periods as well.

For bank officers in India, this shows the RBI is getting creative to handle the massive pile of cash in the system. Beyond just managing liquidity, these swaps help the RBI trim its 'FX forward book' (a record of future currency promises). At the end of July, the RBI had net forward dollar liabilities of about $137 billion. By doing these transactions, they can balance their books while keeping the rupee stable.

Market experts like Gaura Sen Gupta from IDFC FIRST Bank suggest that the RBI might need to drain about ₹7 trillion using a mix of VRRR and these swap operations. For customers, this means the RBI is working hard to keep inflation in check by ensuring there isn't too much easy money in the system. Moving forward, bankers should watch if the RBI continues these swaps into November or if they return to aggressive VRRR auctions to manage the record-high liquidity levels.
