Rupee Support: RBI Steps In as NDF Contracts Mature

The Reserve Bank of India likely intervened in the foreign exchange market on Wednesday to support the rupee, three traders told Reuters. The trigger was a batch of maturing contracts in the non-deliverable forwards (NDF) market, which created a wave of dollar demand that pushed the rupee toward fresh lows.

The RBI's tool of choice was a sell-buy swap, traders said. The central bank sells dollars in the spot market and simultaneously agrees to buy them back at a future date. That absorbs rupee liquidity while defending the currency level, without draining reserves permanently. The swap structure matters because it signals the RBI is managing the pace of depreciation, not defending a specific line in the sand.

The NDF Maturity Squeeze

The pressure came from the NDF market, where offshore participants had built up short rupee positions. When those contracts matured, the counterparties needed to deliver dollars onshore. That created a concentrated bid for the greenback in the spot market, exactly the kind of mechanical flow that central banks step into.

Traders said the RBI's intervention was visible in the way spot dollar-rupee traded through the session. The pair opened under pressure, then found a bid near the day's high that looked like official buying. The swap premium also moved, a signature of the sell-buy structure.

What the Swap Tells You

The RBI has a history of using swaps rather than outright spot sales when it wants to manage liquidity alongside the exchange rate. An outright spot sale drains rupee liquidity permanently. A sell-buy swap reverses that effect when the forward leg settles. That distinction matters for short-term rates and for the banking system's cash position.
