The Indian rupee weakened to another historic low on December 17, opening at 91.08 against the US dollar, underscoring sustained pressure on the currency despite intermittent central bank intervention. The move marks a continuation of a trend that has now placed the rupee as the worst-performing currency in Asia this year.

After closing the previous session at 91.03, the currency slipped further at the open as demand for dollars remained firm. Market participants attributed the pressure to persistent foreign institutional investor (FII) selling, lingering uncertainty around an India–US trade agreement, and fragile risk sentiment in domestic equities. Shortly after the open, the rupee recovered modestly to around 90.35, a move traders widely interpreted as the result of intervention by the Reserve Bank of India (RBI).

Currency markets have been steadily pricing in a weaker rupee through 2025. The rupee has now depreciated 5.97 percent year-to-date, significantly underperforming regional peers. By comparison, the Indonesian rupiah is down 3.53 percent, the Philippine peso 1.37 percent, the South Korean won 0.56 percent, while the Hong Kong dollar has slipped just 0.13 percent.

This divergence highlights India’s relative vulnerability to global capital flows at a time when domestic equity markets have struggled to keep pace with record highs in other global indices. Foreign investors have remained net sellers, putting pressure on both equity valuations and the currency, reinforcing a negative feedback loop.

What is changing

The key shift is not a single-day move but the normalization of the 91 level for the rupee. What was once considered a psychological threshold has now been breached repeatedly. Traders report that importers continue to hedge aggressively, while exporters remain reluctant to sell dollars at current levels, further skewing demand-supply dynamics.

At the same time, the RBI has stepped up liquidity operations. A recent currency swap reportedly infused around ₹45,000 crore into the system, followed by a planned bond purchase of ₹50,000 crore to ease rupee liquidity conditions. While these measures have helped smooth intraday volatility, they have not reversed the broader depreciation trend.

Why it matters

A weaker rupee has direct and indirect implications for India’s macroeconomic stability. On the positive side, depreciation can support export competitiveness over time. However, the current move is driven more by capital outflows than by trade fundamentals, which limits the upside.

India remains heavily dependent on imports for crude oil, electronics, and capital goods. Sustained rupee weakness raises input costs, feeds into imported inflation, and complicates monetary policy transmission. For policymakers, the challenge is to prevent disorderly currency moves without burning through reserves or tightening domestic liquidity excessively.

From a credibility standpoint, repeated record lows risk anchoring expectations of further depreciation, which can accelerate hedging activity and speculative positioning.

Official views and policy signals

Market commentary suggests that the RBI remains focused on curbing sharp volatility rather than defending any specific level. Liquidity injections via swaps and bond purchases indicate a preference for indirect intervention, allowing the rupee to adjust gradually while preventing panic-driven moves.

Currency strategists note that without visible progress on trade negotiations or a reversal in FII flows, the RBI’s actions are likely to remain defensive rather than directional.

Potential business and market implications

For Indian equity markets, a weak rupee is a double-edged sword. Export-oriented sectors such as IT services and select manufacturing segments may benefit at the margin. However, the broader market impact has so far been negative, as foreign outflows dominate and currency weakness reinforces risk aversion.

Debt markets face a more nuanced impact. While liquidity infusion supports bond prices in the near term, persistent currency depreciation could deter foreign bond investors and increase term premia over time.

Corporates with unhedged foreign currency liabilities face higher balance sheet risk, particularly in sectors reliant on imported raw materials.

Market impact on India

The rupee’s slide has coincided with equity underperformance relative to global peers, highlighting India’s sensitivity to external capital flows. Continued weakness could pressure benchmarks further if foreign selling persists.

Sector impact

Import-intensive sectors such as energy, aviation, and electronics face margin pressure, while export-linked sectors may see limited relief. Banking and financials remain exposed indirectly through corporate credit risk and market volatility.

Bull vs Bear scenario

In a bullish scenario, progress on India–US trade talks and stabilization in global capital flows could help anchor the rupee below 91, reducing volatility. In a bearish case, prolonged foreign selling and external shocks could push the currency gradually toward the 92 level, as already indicated by market participants.

Key risks

The primary risks include prolonged trade uncertainty, sharper global risk-off episodes, and limits to RBI intervention effectiveness. A sustained rise in imported inflation could further complicate policy choices.
