RBI Plans $5 Billion Swap to Stabilise Rupee

The Reserve Bank of India (RBI) announced a $5 billion dollar–rupee buy–sell swap operation scheduled for mid-December, signalling proactive intervention to stabilise the rupee amid heightened global currency volatility. The move comes in the context of a strong US dollar, fluctuating capital flows, and a decline in India’s foreign exchange reserves earlier in 2025, which had reduced the RBI’s immediate buffer against external shocks.

A buy–sell swap involves the RBI purchasing US dollars from the market in the spot segment while simultaneously committing to sell the same amount of dollars at a future date through a forward contract. This mechanism allows the central bank to temporarily augment its foreign exchange reserves without permanently injecting rupee liquidity into the system. As a result, it supports the rupee while maintaining monetary policy transmission and liquidity management objectives.

The RBI has used swap instruments in the past as a flexible tool to manage external sector pressures. Compared to direct dollar sales, swaps help conserve reserves and smooth exchange rate volatility rather than targeting a specific exchange rate level. The current operation reflects the RBI’s stated approach of preventing excessive volatility while allowing market-determined currency movements.

Currency stability has broader macroeconomic implications. A sharply depreciating rupee can raise import costs, especially for crude oil, fertilisers and essential commodities, thereby feeding into domestic inflation. Exchange rate uncertainty can also affect investor sentiment, foreign portfolio inflows and external borrowing costs for Indian firms. By strengthening its reserve position, the RBI enhances its credibility and ability to respond to sudden external shocks such as geopolitical tensions, global financial tightening or abrupt capital outflows.

At the same time, policymakers must balance intervention with long-term fundamentals. Sustained currency stability ultimately depends on strong economic growth, manageable current account deficits and stable capital flows. Excessive intervention may also invite scrutiny or distort market signals.

Why it matters:
The $5 billion swap underscores the RBI’s commitment to maintaining financial and external stability. By bolstering reserves and managing volatility, the move supports inflation control, import affordability and investor confidence, reinforcing India’s macroeconomic resilience in an uncertain global environment.
