How a Weaker Rupee Impacts Indian Company Valuation

The Indian rupee has weakened significantly against the US dollar through 2025 and into 2026, crossing the ₹90-per-dollar level for the first time. For Indian businesses with significant foreign currency exposure, this is more than a currency-market development. Changes in the INR-USD exchange rate can affect revenue, costs, debt obligations, cash flows, and ultimately business valuation.

For a valuation professional, the key question is not simply whether the rupee has depreciated. It is how much of the company's reported financial performance is being driven by currency movements rather than by the underlying business.

How Does INR Depreciation Affect Business Valuation?

The impact of rupee depreciation depends largely on a company's foreign currency exposure.

Export-oriented companies may benefit because their dollar revenues translate into more rupees. Import-dependent businesses, on the other hand, can face higher costs as imported raw materials, components, and crude oil become more expensive in INR terms.

Companies with foreign currency debt face another source of pressure because a weaker rupee can increase the rupee cost of servicing dollar-denominated borrowings.

As a result, INR depreciation can have a positive or negative impact on company valuation depending on the company's revenue, cost, and financing exposure to foreign currencies.

Impact on Export-Oriented Companies

Indian IT services companies, pharmaceutical exporters, and other businesses earning substantial revenue in foreign currencies can benefit from a weaker rupee.

For example, if a company earns $100 million and the exchange rate moves from ₹80 to ₹90 per dollar, the same dollar revenue translates from ₹8 billion to ₹9 billion. However, this does not necessarily mean the underlying business has grown by 12.5%.

This distinction is important when performing a DCF valuation. Historical revenue growth may partly reflect currency translation rather than higher sales volumes, stronger pricing, or increased demand.

A valuer should therefore separate organic business growth from exchange-rate-driven growth before using historical trends to forecast future revenue.

Impact on Import-Dependent Businesses

The opposite can happen for companies that rely heavily on imported materials, equipment, components, or crude oil. A weaker rupee increases the INR cost of these inputs. If the company cannot pass the additional cost on to customers, profit margins can decline.

From a valuation perspective, it is important to determine whether this margin pressure is temporary or represents a longer-term change in the company's economics. Simply projecting historical margins without considering currency exposure can overstate future cash flows. At the same time, assuming that a temporary currency shock will permanently reduce margins can undervalue the business.

Effect of INR Depreciation on Foreign Currency Debt

Companies with dollar-denominated debt can also see their financial position affected by rupee depreciation. When the rupee weakens, the rupee equivalent of foreign currency borrowings increases. Interest and debt-servicing costs can also become more expensive in INR terms, depending on the company's hedging arrangements. For companies with significant External Commercial Borrowings or other foreign currency liabilities, exchange-rate assumptions should therefore be incorporated into the valuation model.

This is particularly relevant when calculating free cash flow to equity, as higher financing and debt-servicing costs can affect the cash ultimately available to shareholders.

INR Depreciation and Cross-Border Transactions

Currency movements also matter in cross-border acquisitions and investments. A weaker rupee can make Indian assets relatively cheaper in US dollar terms for foreign investors, assuming the underlying INR valuation remains unchanged. Conversely, Indian companies acquiring overseas businesses may have to spend more rupees to fund the same dollar-denominated transaction.

For transactions involving FEMA pricing requirements, the valuation may be determined in INR, but the ultimate economic cost or proceeds for a foreign investor can still change as exchange rates move between the valuation date and transaction date.

What Should Valuers Consider?

When preparing a business valuation during a period of significant INR volatility, valuers should:

• Separate currency-driven growth from genuine operating growth.
• Analyse the company's foreign currency revenue and cost exposure.
• Model the impact of exchange rates on foreign currency debt.
• Clearly document exchange-rate assumptions in DCF projections.
• Consider sensitivity analysis for different INR-USD scenarios.
• Avoid automatically carrying unusual currency-driven historical growth into the forecast period.

Final Takeaway

INR depreciation can materially affect Indian company valuation, but the impact is not the same for every business.

Exporters may see higher INR-reported revenue, while import-dependent companies can face margin pressure and businesses with dollar debt may experience higher financing costs. The important issue for a valuation is to distinguish these currency effects from the company's actual operating performance. A strong valuation model should therefore treat the exchange rate as an explicit assumption rather than allowing currency movements to quietly distort revenue growth, margins, or cash flow forecasts. This becomes especially important when valuing Indian companies during periods of significant INR volatility.
