How INR Depreciation Affects Indian Company Valuation

The rupee has weakened substantially against the dollar through 2025 and into 2026, breaching the 90 mark for the first time in its history and trading in a genuinely wide range through the year, driven by a persistent trade deficit, sustained foreign portfolio outflows, and broader global dollar strength. For any company earning or owing money in dollars, this kind of sustained currency movement flows directly into valuation, not just the quarterly commentary on forex.
Why the Effect Runs in Opposite Directions Across Sectors
A depreciating rupee doesn't affect every Indian business the same way. It splits companies into fairly clear winners and losers based on their currency exposure.
IT services and pharmaceutical exporters benefit directly. These companies earn revenue in dollars but report results in rupees, so a weaker rupee mechanically boosts reported earnings in INR terms, even without any change in the underlying dollar-denominated business. For a DCF valuation of a genuinely dollar-revenue business, this means rupee depreciation can flow straight into apparent earnings growth that has nothing to do with actual operating performance.
Import-dependent and oil-linked businesses face real margin pressure. Companies reliant on imported raw materials, components, or crude oil see input costs rise in rupee terms as the currency weakens, squeezing margins unless they can pass the increase through to customers. A valuation model that doesn't explicitly separate currency-driven cost inflation from genuine operational cost pressure risks misreading a temporary currency effect as a structural margin problem, or vice versa.
Companies with dollar-denominated debt face a direct balance sheet impact. A weaker rupee increases the actual rupee cost of servicing foreign currency borrowings and External Commercial Borrowings, which shows up directly in interest expense and, for companies with significant such exposure, can meaningfully affect free cash flow available to equity holders.
Why This Matters More Than It Might Seem for a DCF
Because rupee depreciation genuinely changes reported revenue, cost, and financing figures without necessarily reflecting any real change in the underlying business, a valuer building a DCF model off historical financials needs to explicitly separate currency-driven effects from genuine operating trends before projecting them forward. A dollar-revenue exporter has grown its revenue historically. If that growth was partly driven by currency the dollar-revenue exporter should not simply extend the rate into the future when the rupee movement is genuinely uncertain. Forecasts for 2026 vary widely depending on assumptions, about US-India trade relations and oil prices.
Implications for Cross-Border Transactions
Rupee depreciation directly affects the economics of foreign investment into India, and Indian outbound investment abroad, in opposite directions. A weaker rupee makes Indian assets cheaper for foreign investors in dollar terms, all else equal, which can support foreign acquisition activity even where the Indian target's own rupee-denominated valuation hasn't changed. The reverse holds for Indian companies acquiring abroad, where a weaker rupee means the same dollar-denominated acquisition costs more in rupee terms.
For FEMA pricing specifically, the valuation itself is typically conducted in rupee terms, but the effective dollar cost or proceeds for a foreign party shift as the exchange rate moves between the valuation date and the actual transaction date.A gap that matters more during a period of pronounced currency volatility than during a stable exchange rate environment.
Practical Implications for a Valuation Prepared Today
Separate currency-driven results from genuine operating performance in the historical financial analysis, particularly for exporters and import-dependent businesses where the distinction is largest.
Model foreign currency debt servicing costs explicitly, rather than assuming a static rupee cost that doesn't reflect ongoing currency risk for companies with meaningful dollar-denominated borrowings.
Treat the rupee's trajectory as a genuine, documented assumption within cash flow projections for dollar-revenue or import-dependent businesses, rather than embedding it silently within a blended growth or margin assumption.
A currency move big as what the rupee is seeing through 2025 and 2026 doesn’t just mess with one quarter’s earnings. It goes deeper. It changes the long-term numbers that people use to value a company. It distorts the operating performance. The actual trend. That gets hidden behind all the currency noise.. It affects every international deal that the valuation is tied to. This isn’t a short-term bump. It’s a shift, in how everything's measured and priced. Getting this separation right is what distinguishes a valuation grounded in real business performance from one that's quietly measuring currency movement instead.
