Examine the tools available with the RBI to manage capital account volatility and defend the rupee during periods of global monetary tightening.

When global interest rates rise, capital flows out of emerging markets and the rupee comes under pressure. Since India retains a partially convertible capital account, the RBI holds a graded toolkit — market intervention, swap windows, capital-flow regulation and monetary signalling — rather than a single defence.

Forex market intervention and swap windows

• Direct spot and forward dollar sales from reserves, smoothing volatility without targeting a level.
• Concessional swap facilities that mobilise dollars through banks instead of drawing down reserves. The RBI's swap window for FCNR(B) deposits, ECBs and Overseas Foreign Currency Borrowings, operationalised on 8 June 2026, had drawn USD 40.8 billion by 31 July 2026 [1][2], rising to USD 72.85 billion by 21 August 2026, with FCNR(B) deposits the bulk [3].
• The design echoes the 2013 "taper tantrum" swap window, where banks swapped fresh FCNR(B) deposits of three-year tenor at a concessional 3.5% per annum [4].

Regulating capital flows

• Calibrating the ECB framework — minimum average maturity, end-use and hedging norms; only ECBs of three years and above qualify for the current swap [1].
• Adjusting NRI deposit interest-rate ceilings and reserve requirements to attract stable, longer-tenor inflows [1].

Monetary and liquidity tools

• Policy rate and liquidity operations to preserve the interest-rate differential that anchors debt inflows.
• Macroprudential buffers — a large reserve stock providing import cover and signalling credibility.

Limitations

• Swap-based mobilisation creates future repayment obligations and concentrates redemption risk at maturity.
• Intervention can tighten domestic rupee liquidity, and prolonged defence risks reserve depletion.

Overall, the RBI's response has shifted from reserve-burning defence towards liability-side mobilisation that raises non-debt-creating cushions while preserving reserves. Sustained resilience, however, rests on wider export competitiveness, deeper hedging markets and stable FDI — aligning currency management with the broader goal of durable external-sector stability.
