Rupee Volatility: SBI Research Urges RBI Action in 2026

Introduction: Rupee Faces Mounting Pressure

The Indian rupee is navigating a period of heightened volatility, driven by a confluence of global headwinds and shifting domestic market dynamics. Recent trading sessions have seen the currency breach significant psychological levels, prompting calls for proactive measures from the Reserve Bank of India (RBI). A comprehensive report from SBI Research, released on March 30, 2026, argues that while India's economic fundamentals remain robust, timely and calibrated intervention is necessary to stabilize the currency and prevent excessive depreciation.

Global Factors and Capital Outflows

The primary driver behind the rupee's recent weakness is a challenging global environment. Heightened geopolitical tensions, including the ongoing crisis in West Asia and trade frictions stemming from US tariffs imposed in April 2025, have fueled a risk-off sentiment among global investors. This has led to a structural shift in capital flows. According to SBI Research, the era of abundant foreign portfolio investment (FPI) that supported the rupee before 2014 has diminished significantly. Net portfolio inflows, which averaged $162.8 billion annually between 2007 and 2014, have dropped to an average of $17.7 billion between 2015 and 2025. The year 2025 alone witnessed FPI outflows nearing $19 billion, placing sustained pressure on the currency.

A Different Scenario from 2013

While the current volatility draws parallels to the 2013 taper tantrum, SBI Research emphasizes that the underlying macroeconomic conditions are fundamentally different. In 2013, India was grappling with a high current account deficit and fiscal concerns. Today, the economy is supported by strong domestic-led growth and a formidable external position. India's foreign exchange reserves stand at over $100 billion, providing import cover for more than ten months. Furthermore, short-term external debt remains manageable, at less than 20% of total reserves. This strong foundation gives the RBI significant firepower to intervene without resorting to drastic measures like the Foreign Currency Non-Resident (FCNR-B) deposit schemes used in the past.

SBI Research's Key Recommendations

To address the current challenges, SBI Research has proposed a multi-pronged strategy focused on targeted, non-disruptive interventions. The report argues against using overseas debt instruments due to high hedging costs and unfavorable interest rate differentials. Instead, it advocates for the direct and measured use of India's substantial forex reserves to deter speculative attacks and anchor market expectations.

A Special Window for Oil Marketing Companies

A key recommendation is the creation of a separate foreign exchange window for Oil Marketing Companies (OMCs). OMCs represent a significant and consistent source of dollar demand, requiring approximately $150–$100 million daily. By channeling this structural demand through a special RBI window, the central bank could isolate it from the speculative and sentiment-driven flows in the open market. This would provide a clearer picture of genuine supply-demand dynamics and improve the effectiveness of other policy measures.

Revisiting Bank Open Position Limits

The report also addresses the recent RBI circular capping the Net Open Position (NOP) for banks at $100 million. While intended to rationalize positions, this move may have inadvertently created a divergence between onshore and offshore markets, leading to liquidity pressures. SBI Research suggests that this limit should be applied only to banks' trading books rather than their entire balance sheets. This adjustment would prevent operational challenges, especially as banks facilitate genuine fund withdrawals by foreign investors.

Key Financial and Market Indicators

To provide context to the ongoing currency movements, the following table summarizes critical data points highlighted in the analysis.

Analysis: A Call for Calibrated Action

The core message from SBI Research is not one of alarm but of prudence. The recommendation is for the RBI to act decisively but without triggering market panic. The proposed measures are designed to be surgical, addressing specific pressure points like OMC demand and interbank liquidity rather than implementing broad, restrictive capital controls. The suggestion to consider tools like 'Operation Twist' further indicates a preference for using existing monetary policy instruments to manage the interconnectedness of currency and bond markets. This approach acknowledges that India's strong fundamentals provide the space for a measured response focused on managing volatility rather than defending a specific rupee level.

Medium-Term Outlook for the Rupee

Despite the near-term pressures, the report maintains a constructive medium-term outlook. The analysis suggests that the current depreciating regime is cyclical and likely to last for approximately six more months. Based on historical patterns, SBI Research projects that the rupee could exit this phase and stage a meaningful recovery in the second half of 2026. A potential appreciation of around 6.5% could see the currency move back towards the 87-per-dollar mark, assuming an easing of geopolitical risks and a stabilization of capital flows.

Conclusion

In summary, SBI Research posits that while the Indian rupee faces significant external pressures, the country's strong economic fundamentals provide a solid defense. The report calls for unequivocal and unambiguous support from the RBI through timely, targeted, and well-communicated interventions. By strategically using its forex reserves and implementing specific measures for oil companies and banks, the central bank can effectively manage volatility, anchor market sentiment, and pave the way for a potential recovery in the latter half of the year.
