How Rupee Depreciation Affects Nifty Earnings Differently for IT Exporters vs Domestic Facing Companies

Last Reviewed and Updated: 17 Aug 2026

On June 18, 2026, a hawkish surprise from the US Federal Reserve pushed the dollar higher and pressured the rupee, and Infosys, TCS and HCL Technologies all fell that day. On paper, a weaker rupee is supposed to be good news for exactly these companies. It is, for their earnings. It was not, that day, for their stock prices, because the same event that weakened the rupee was simultaneously making global investors nervous about the exact kind of company IT services firms are.

A single currency move can help a company's numbers and hurt its stock price in the same week, sometimes the same session, and understanding why requires separating two different questions that get treated as one far too often.

That is only the first layer of complexity. A finished goods exporter earning in dollars but importing half its raw materials, a pharmaceutical company selling generics to the United States while sourcing active ingredients from China, and an airline paying for jet fuel and aircraft leases in dollars while collecting fares in rupees, all read the same headline currency number and experience something entirely different from it. Rupee depreciation is not one story for Nifty earnings. It is several running in parallel, sometimes in the same company at once.

The starting mechanism is simple arithmetic before anything else complicates it. A company that bills a client in dollars, and reports its results in rupees, converts every dollar it earns into more rupees when the exchange rate moves from, say, Rs 90 to Rs 96 per dollar.

Nothing about the underlying business, the client relationship, the volume of work, or the price charged in dollar terms needs to change at all for reported rupee revenue and profit to rise. This is precisely why Indian IT services and export oriented pharmaceutical companies, whose revenue is overwhelmingly dollar, euro or sterling denominated, are the sectors most directly and mechanically rewarded by a weakening rupee, and why it shows up first and most cleanly in their numbers rather than anywhere else in the market.

For Indian IT services specifically, this sensitivity has been measured closely enough to state with real precision. Every 1% depreciation in the rupee against the dollar translates to roughly 40 to 50 basis points of improvement in rupee reported earnings per share for large cap IT companies, without any change in the underlying business.

The rupee moved from around Rs 89.86 at the start of 2026 to Rs 96.26 by late May, a depreciation of roughly 7.1% over less than five months, adding an estimated 3% to 4% to FY27 rupee EPS for large cap IT purely from the currency move, layered on top of whatever organic revenue growth the business itself delivers.

Indian IT companies typically earn 80% to 85% of revenue in dollars, euros and sterling combined, with Infosys, TCS, Wipro, HCL Technologies and Tech Mahindra all drawing more than 75% of revenue from dollar denominated contracts, which is why this sensitivity is concentrated so heavily in this one sector.

Date	Rupee per USD	Approximate Move
Start of 2026	Rs 89.86	Baseline
Late May 2026	Rs 96.26	Depreciation of roughly 7.1% year to date, adding an estimated 3% to 4% to FY27 large cap IT rupee EPS

Here is the genuinely counterintuitive part. On June 17 and 18, 2026, the US Federal Reserve held its policy rate steady but delivered a hawkish surprise, with roughly half its policymakers signalling a possible rate hike later in the year, and two year US Treasury yields jumped as the market repriced toward a rate hike narrative rather than a rate cut one. The dollar strengthened and the rupee weakened as a direct result, precisely the kind of move that mechanically helps IT earnings.

Yet Infosys, TCS and HCL Technologies all fell that same day, because a hawkish Fed raises the discount rate applied to a growth oriented sector's future earnings and raises concern about the very technology budgets of the US corporate clients IT services companies depend on. The earnings channel and the stock price channel were pulling in opposite directions at the same time, driven by the same underlying event, and only one of the two showed up in the day's headline stock move.

On June 18, 2026, a weaker rupee was still doing exactly what it always does to IT earnings. It was the reason behind the weaker rupee, a hawkish Fed, that was doing something else entirely to IT stock prices, on the very same day.

Companies dependent on imported inputs face the mirror image of the IT sector's benefit. Oil marketing companies import crude in dollars, so a weaker rupee directly raises the rupee cost of every barrel, squeezing margins unless retail fuel prices are allowed to rise in step. Airlines face a similar bind from two directions at once, paying for jet fuel and, often, aircraft leases in dollars while collecting the large majority of fares in rupees.

Note: the rupee has eased slightly since the late-May 2026 peak of weakness cited above, trading around Rs 95.6 per dollar as of mid-August 2026, though still meaningfully weaker than the Rs 89.86 starting point for the year. The mechanism described throughout this article applies regardless of the exact current rate.

FMCG companies reliant on imported raw materials, certain chemicals, packaging inputs and specialty ingredients among them, see input costs rise directly, and passing that through to price sensitive domestic consumers is neither immediate nor guaranteed. Electronics importers face the same arithmetic in reverse to the export side: India's electronics exports actually grew sharply through this period, but firms in the same broader category that rely on imported components such as specialty resins and hardeners found part of that currency benefit offset by costlier inputs.

Sector	Effect of Rupee Depreciation	Why
IT services	Benefits	Revenue is 80% to 85% dollar, euro and sterling denominated; costs are mostly rupee
Export oriented pharmaceuticals	Benefits	Generic drug exports to the US and Europe earn dollars; much of the cost base is rupee denominated
Oil marketing companies	Hurt	Crude oil is imported and priced in dollars
Aviation	Hurt	Jet fuel and many aircraft leases are dollar denominated; fares are collected mostly in rupees
Import dependent FMCG	Hurt	Raw materials and packaging inputs sourced abroad cost more in rupee terms
Finished goods exporters using imported components	Mixed	Export revenue benefits while imported input costs rise at the same time

A meaningful share of Indian exporters do not sit cleanly on either side of this divide. A company manufacturing finished electronics or specialty chemicals for export earns dollars on the way out but often imports the components or raw materials that go into the product on the way in, meaning a rupee move helps one line of the cost sheet while hurting another simultaneously.

The net effect for these businesses depends on the relative size of imported input costs against export revenue, and on how much pricing flexibility the company actually has with its own customers and suppliers, which varies company by company far more than it does for a pure IT services exporter with minimal imported cost exposure.

The currency benefit to an exporter's margin is not guaranteed to stay in the company's pocket indefinitely. As one analyst covering the software exporters put it, a weaker rupee provides an immediate cushion that instantly expands operating margins and lifts near term earnings, but the arrangement tends to have a clear expiry, since clients under their own budget pressure eventually come back to the table to renegotiate pricing and claw back some of what the exporter gained.

Biocon's chairperson Kiran Mazumdar Shaw made a similar point about pharmaceutical exporters, expressing hope that companies would use the currency benefit to genuinely improve profitability rather than compete it away by underpricing to win market share, a pattern she described as already visible among some Indian pharmaceutical companies. In both sectors, the mechanical benefit is real in the near term, but whether it survives into a durable, multi year margin improvement depends on pricing discipline that is far from guaranteed.

A separate, less visible channel runs through corporate balance sheets rather than income statements. Companies carrying unhedged foreign currency debt see the rupee value of that debt rise when the currency weakens, a translation effect that can show up as a reported loss even without any change in the business's actual operations, and refinancing that debt becomes more expensive in a period of sustained dollar strength.

This risk is concentrated in capital intensive, import heavy sectors, aviation and select infrastructure and manufacturing names among them, compounding the operating cost pressure those sectors already face from imported inputs with a second, balance sheet level currency exposure that a simple revenue and cost analysis would miss entirely.

A software exporter's currency windfall and an airline's currency bill arrive from the exact same headline number. Nobody sends a different rupee to each company.

A few practical conclusions follow from how unevenly a single currency move actually spreads across Nifty earnings:

• Do not assume rupee weakness is automatically good for an IT stock's price simply because it is reliably good for IT earnings. The same move can arrive alongside a global rate environment that pressures the stock through a completely separate channel.

• Check a company's actual cost structure, not just its revenue exposure, before assuming it benefits or suffers from a currency move. An exporter with significant imported inputs is not a clean beneficiary the way a pure services exporter is.

• Treat a currency driven earnings upgrade as a near term tailwind rather than a permanent structural improvement, since clients and competitive pressure have both been known to claw back part of the benefit over subsequent quarters.

• Check a company's foreign currency borrowings, not just its trading revenue and costs, since unhedged debt creates a separate exposure to rupee moves that a simple operating margin analysis will not capture.

• Remember that a large, disorderly currency move creates broader risk off pressure across the whole market, including for the sectors that benefit mechanically, so a beneficiary sector is not automatically insulated from a bad day simply because the currency itself is moving in its favour.
