The Reserve Bank of India (RBI) stepped into the currency market this week, orchestrating a dramatic turnaround for the Indian rupee. On Wednesday, the domestic currency recorded its most significant single-day gain against the US dollar in seven months, effectively halting a precipitous decline that had alarmed markets.
The Intervention and Its Immediate Impact
This forceful move involved the central bank selling a substantial amount of US dollars, thereby increasing their supply relative to the rupee. This action boosted the rupee's relative price. The intervention followed a period of intense pressure on the currency. By the day's close, the rupee had appreciated by 0.7%, moving from an exchange rate of 91.05 to 90.09 against the dollar. Intraday, the gain was even more pronounced, exceeding 1%.
The RBI's action was a direct response to a worrying trend. Prior to Wednesday's move, the rupee had depreciated by over 6% in the past year, a pace that was almost two to three times its historical average rate of decline against the greenback. The speed of the fall accelerated notably from mid-November, with the currency losing 3% of its value since November 15. At one point, it slid from 90 to 91 against the dollar in just ten days, a move the RBI likely viewed as excessively volatile.
Policy Stance and the Debate on Depreciation
While the intervention stabilised the market, it reignited a debate on the optimal approach for the rupee. RBI Governor Sanjay Malhotra, during the monetary policy review on December 5, outlined the bank's philosophy. He stated that the RBI allows markets to determine the rupee's value and does not target specific levels or bands. The objective, he clarified, is solely to curb "abnormal or excessive volatility."
However, some analysts argue that the current macroeconomic environment presents a unique opportunity. With domestic inflation running below the RBI's comfort zone and global crude oil prices remaining subdued, the risks associated with a weaker rupee are mitigated. A depreciation typically makes imports costlier, fueling inflation, but these conditions suggest that effect would be minimal now. Therefore, this could be an opportune moment for the RBI to allow the currency to depreciate organically, reflecting broader economic fundamentals.
The Long-Term Path for the Rupee
Ultimately, central bank interventions are tools for managing volatility, not for setting a long-term direction. In a globally integrated economy like India's, the rupee's true equilibrium will be determined by fundamental factors. These include the country's export and import dynamics, the flow of foreign capital, and overall economic health. While the RBI's recent action provided crucial short-term stability, the rupee's sustainable value must be grounded in these real economic metrics, not sustained by periodic dollar sales.
The episode underscores the delicate balance the RBI must maintain: preventing destabilising panic in the forex market while allowing the currency to adjust to external realities. The rapid 10-day fall from 90 to 91 likely crossed into the territory of "excessive volatility" the Governor mentioned, warranting the response. The coming weeks will reveal whether this intervention marks a temporary pause or a reversal in the rupee's recent trajectory.
