Why a Weak Rupee Doesn’t Always Help India-Understanding the Exchange Rate and Inflation Paradox
When the Exchange Rate Changed Its Job
For decades, economists viewed the exchange rate as one of the most powerful tools for improving a country’s export competitiveness.
The logic appeared straightforward.
If a country’s currency weakened, its exports became cheaper for foreign buyers while imported goods became more expensive for domestic consumers. Rising exports and falling imports gradually reduced the trade deficit, helping restore external balance.
For much of the twentieth century, this mechanism shaped how economists understood international trade.

External Balance ImprovesIt was elegant.
It was intuitive.
And for many economies, it largely worked.
Yet over the past two decades, something unusual has begun to happen.
Countries have increasingly discovered that a weaker currency no longer guarantees stronger export competitiveness.
In several economies—including India—the expected gains from currency depreciation have become progressively smaller, even when the domestic currency continues to weaken.
This raises an important question.
Has the exchange rate itself changed its role in the modern economy?
The Economic Survey increasingly suggests that the answer is yes.
Its recent institutional thinking reflects a broader shift in how India’s external sector is understood. Earlier policy discussions focused primarily on exchange rates, trade deficits, and resilience against external shocks. More recent Surveys increasingly frame external competitiveness as the outcome of deeper structural factors such as manufacturing capability, participation in global value chains, productivity, technological sophistication, and economic complexity. In this framework, the exchange rate remains important, but it is no longer viewed as the primary determinant of long-term competitiveness.
This represents a fundamental change in perspective.
The traditional question was:
How can the exchange rate improve exports?
The emerging question is:
What kind of economy is capable of sustaining a competitive exchange rate?
That reversal lies at the heart of India’s modern external-sector strategy.
The Classical Adjustment Mechanism
To understand why this shift matters, we must first understand the economic model that dominated international trade for decades.
Classical trade theory assumed that imports and exports largely moved in opposite directions.
When a currency depreciated, imported goods became more expensive. Consumers reduced their demand for foreign products and shifted toward domestically produced alternatives.
At the same time, exporters benefited because their products became cheaper in international markets.
As exports increased and imports declined, the trade deficit gradually narrowed.
The exchange rate therefore acted as a self-correcting mechanism for the external sector.
The underlying assumption was simple.
Imports were primarily viewed as consumption, while exports were viewed as production.
The two were connected only through prices.
As long as imports became more expensive and exports became cheaper, the economy would gradually restore external balance.
For much of the twentieth century, this was a reasonable description of how many economies functioned.
Today’s production systems, however, are fundamentally different.
The Structural Change Nobody Talks About
The modern global economy no longer separates imports and exports into two independent activities.
Instead, they have become deeply intertwined.
A smartphone assembled in India contains imported semiconductor chips, display panels, sensors, batteries, and specialised machinery.
Pharmaceutical exports depend on imported Active Pharmaceutical Ingredients (APIs).
Automobile exports rely on imported electronic systems, specialised steel, and precision components.
In each of these industries, imports are not competing with domestic production.
They are part of domestic production.
This is one of the most important structural transformations in international trade.
The Economic Survey highlights that India’s participation in Global Value Chains increasingly depends on the smooth import of intermediate goods. In several manufacturing sectors, imported components are not substitutes for exports but essential inputs into them. In fact, evidence cited by the Survey shows that, in complex manufacturing sectors such as automobiles and pharmaceuticals, a 1% increase in imported intermediate goods is associated with more than a 1% increase in finished exports, demonstrating that import facilitation has become a prerequisite for export competitiveness.
This changes the economics of exchange rates completely.
When the rupee depreciates today, imports certainly become more expensive.
But those higher import costs no longer affect only consumers.
They also increase the cost of producing India’s own exports.
The exchange rate has therefore acquired a second and increasingly important role.
It is no longer merely an instrument for influencing trade flows.
It has become a channel through which inflation enters the production system itself.
That is where the modern exchange-rate paradox begins. The question is no longer whether a weaker rupee makes exports cheaper. The real question is whether those exports can remain competitive after the higher cost of imported production inputs has worked its way through the entire economy.
That journey—from currency depreciation to domestic inflation—is the inflationary feedback loop that now defines the exchange-rate debate.
The Inflationary Feedback Loop
The classical adjustment mechanism assumed that a weaker currency worked primarily through prices in international markets.
Modern manufacturing works through costs inside domestic factories.
That difference changes everything.
When imports consisted largely of finished consumer goods, depreciation mainly influenced household purchasing decisions. Imported products became more expensive, encouraging consumers to shift toward domestic alternatives, while exporters benefited from lower prices in foreign markets.
Modern manufacturing increasingly depends on imported intermediate goods. As a result, exchange-rate movements now affect production costs before they influence export prices.
In other words, imports are no longer merely competing with domestic production.
They have become one of its essential building blocks.
The Economic Survey identifies this as a structural feature of modern manufacturing. Participation in Global Value Chains depends heavily on imported intermediate goods, and in sectors such as automobiles and pharmaceuticals, a 1% increase in imported intermediate goods is associated with more than a 1% increase in finished exports. Rather than being substitutes, imports and exports increasingly complement one another.
This transforms the role of exchange rates.
A weaker rupee no longer affects only the prices of imported consumer goods.
It directly affects the cost of producing India’s exports.
The Inflationary Feedback Loop
This creates an Inflationary Feedback Loop.
Instead of acting purely as an export stimulus, currency depreciation begins by increasing production costs across the economy.
The transmission mechanism is remarkably straightforward.

Export Competitiveness WeakensUnlike the classical adjustment mechanism, where depreciation immediately improved competitiveness, the modern adjustment begins with cost inflation.
Every imported barrel of crude oil becomes more expensive.
The mechanism became particularly visible during the recent oil shock, when crude oil prices rose by nearly 53%. Since crude oil enters transportation, logistics, fertilisers, petrochemicals and manufacturing, the increase rapidly spread through production costs across the economy before eventually feeding into consumer prices.
Every imported semiconductor costs more.
Industrial machinery, fertilisers, electronic components, speciality chemicals, and transportation inputs all become costlier in rupee terms.
Manufacturers therefore face higher production costs even before they sell a single product.
The exchange rate shock enters the factory long before it reaches the export market.
This explains why exchange-rate depreciation increasingly behaves like an inflation shock rather than a simple export incentive.
The Corporate Markup Trap
Whether higher production costs remain confined to businesses or spread throughout the economy depends on one crucial question.
Who absorbs the shock?
In theory, firms could accept lower profit margins until exchange-rate conditions improve.
In reality, that is rarely how modern businesses operate.
Many firms follow markup pricing.
Instead of fixing prices independently of costs, they determine selling prices by adding a profit margin over their variable production costs.
When imported inputs become more expensive, selling prices also rise.
The burden of currency depreciation is therefore transferred from producers to consumers.
Evidence from the CMIE Prowess database suggests that this behavior is one of the central reasons why nominal depreciation increasingly generates inflation instead of export competitiveness. Evidence from the CMIE Prowess database shows that Indian non-financial firms maintained a markup ratio of 1.58 in 2023, indicating that higher input costs are frequently passed on rather than absorbed. As a result, depreciation raises domestic prices, causing the real exchange rate to appreciate and offsetting much of the competitive advantage expected from a weaker rupee.
This is the Corporate Markup Trap.
The exchange rate attempts to reduce export prices.
Corporate pricing decisions simultaneously push domestic prices upward.
The two forces begin working against each other.
The result is an economy where nominal depreciation and domestic inflation increasingly move together.
In effect, firms protect profit margins while consumers absorb the exchange-rate shock. The very depreciation intended to improve export competitiveness begins to generate inflation that gradually neutralises its own advantage.
The Technology Trap
Paradoxically, this challenge becomes larger as India’s manufacturing ambitions become more sophisticated.
Traditional manufacturing often depended on relatively simple domestic inputs.
Advanced manufacturing is different.
Electric vehicles require battery cells, power electronics, and specialised minerals.
Semiconductor assembly depends on imported fabrication equipment and high-precision components.
Modern pharmaceutical production relies on globally sourced intermediate chemicals.
Precision engineering requires imported machine tools and specialised alloys.
The more India moves toward technologically sophisticated manufacturing, the greater the share of imported intermediate goods embedded within production.
The evidence suggests that this creates a Technology Trap. As India climbs the technological ladder, manufacturing becomes increasingly dependent on imported high-value components. Consequently, exchange-rate depreciation affects a larger proportion of production costs, making advanced manufacturing more vulnerable to imported inflation than traditional industries.
Ironically, the very transformation needed to build a globally competitive manufacturing sector also increases the economy’s sensitivity to exchange-rate shocks.
This is one of the defining paradoxes of modern industrialisation.
When the Exchange Rate Starts Working Against Itself
The cumulative effect of these processes is profound.
The purpose of currency depreciation is to make exports more competitive.
Yet depreciation simultaneously increases the cost of producing those exports.
Businesses pass these higher costs into domestic prices.
Inflation rises.
The competitive advantage that depreciation was supposed to create gradually disappears.
The exchange rate, in effect, begins to cancel out its own objective.
The broader implication is that, in India’s current production structure, nominal depreciation is no longer primarily an export tool; it has increasingly become an inflationary transmission mechanism. The key issue today is not whether the rupee weakens, but whether domestic inflation rises quickly enough to neutralise any competitive gain from that depreciation.
But how do economists know that this neutralisation is actually taking place?
The answer lies in the difference between Nominal Effective Exchange Rates (NEER) and Real Effective Exchange Rates (REER)—two indicators that reveal why looking only at the rupee-dollar exchange rate can be deeply misleading.
Looking Beyond the Dollar — Why Economists Focus on the Real Exchange Rate
Every time the rupee weakens against the US dollar, the same conclusion usually follows.
A weaker rupee should make Indian exports cheaper.
At first glance, the argument appears convincing.
If an American buyer could previously purchase ₹80 worth of Indian goods with one dollar and can now purchase ₹96 worth of goods, Indian products should become more attractive in global markets.
But this conclusion assumes something that may not be true.
It assumes that the cost of producing those goods has remained unchanged.
As we have seen, modern manufacturing does not operate that way.
Currency depreciation raises the cost of imported energy, machinery, electronic components, chemicals, and intermediate goods. Businesses pass many of these higher costs into prices. Domestic inflation begins to rise.
The exchange rate has changed.
The cost of production has changed as well.
This is why economists rarely judge competitiveness by looking at the rupee-dollar exchange rate alone.
Instead, they ask a more important question:
After accounting for inflation, has India actually become more competitive?
That question leads us from the Nominal Effective Exchange Rate (NEER) to the Real Effective Exchange Rate (REER).
The Exchange Rate That Headlines Ignore
Most public discussions focus on a single number—the rupee against the US dollar.
That number is important.
But it tells only part of the story.
India trades with more than one country.
Its exporters compete simultaneously in Europe, the Middle East, East Asia, Africa, and North America.
A meaningful measure of competitiveness therefore cannot depend on only one bilateral exchange rate.
Economists instead use the Nominal Effective Exchange Rate (NEER), which measures the rupee against a weighted basket of currencies representing India’s major trading partners.
NEER answers a simple question:
Has the rupee strengthened or weakened in nominal terms?
But exporters are not paid for exchange rates.
They compete on prices.
If production costs inside India rise faster than those in competing countries, Indian goods become relatively more expensive regardless of what the nominal exchange rate is doing.
To capture this reality, economists adjust the nominal exchange rate for differences in inflation.
The resulting measure is called the Real Effective Exchange Rate (REER), which the Economic Survey describes as a proxy for a country’s external competitiveness. While NEER tracks movements in the currency itself, REER incorporates relative price changes between India and its trading partners, making it a far more meaningful indicator of whether Indian exports have actually become more or less competitive.
The distinction is crucial.
- NEER measures the movement of the currency.
- REER measures the movement of competitiveness.
The two often move together.
Increasingly, they do not.
When the Nominal and the Real Begin to Diverge
In the classical adjustment mechanism, depreciation of the nominal exchange rate automatically translated into improved competitiveness.
A weaker currency made exports cheaper.
Domestic inflation remained relatively contained.
As a result, the real exchange rate also depreciated.
The exchange rate achieved exactly what policymakers expected.
Today’s production structure has fundamentally altered that relationship.
Currency depreciation still occurs.
But depreciation also raises the cost of imported production inputs.
Higher production costs feed into domestic inflation.
As inflation accelerates, much of the competitive advantage created by the weaker currency begins to disappear.
The evidence suggests this as the Currency Paradox. Since the mid-2010s, India has increasingly experienced a situation where the Nominal Effective Exchange Rate depreciated while the Real Effective Exchange Rate appreciated or remained elevated. In other words, the rupee weakened in nominal terms, but rising domestic prices neutralised much of the expected improvement in export competitiveness.
This is a profound departure from classical international economics.
The exchange rate still moves in the expected direction.
Competitiveness does not.
India Parted Company with Many Other Economies
One of the most striking observations is that India’s exchange-rate behaviour has diverged from that observed in many other countries.
Historically, the Reserve Bank of India generally allowed movements in the nominal exchange rate that prevented sustained appreciation of the real exchange rate, thereby preserving export competitiveness.
Beginning in the mid-2010s, however, this relationship changed.
The shift can be understood through a simple comparison.
Earlier, exchange-rate depreciation usually translated into a real improvement in export competitiveness.
Nominal Exchange Rate Depreciated
↓
Domestic Inflation Remained Contained
↓
Real Exchange Rate Also Depreciated
↓
Exports Became More Competitive
Increasingly, however, India’s experience began to look very different.
Nominal Exchange Rate Depreciated
↓
Imported Input Costs Increased
↓
Domestic Inflation Accelerated
↓
Real Exchange Rate Appreciated
↓
Competitiveness Was Neutralised
This divergence is what makes India’s recent exchange-rate experience unusual. The currency continued to weaken in nominal terms, but domestic inflation increasingly offset the competitive gains that depreciation was expected to create.
This observation explains why looking only at the rupee-dollar exchange rate has become increasingly misleading.
A weaker rupee no longer guarantees a more competitive economy.
Domestic inflation may already have erased much of the advantage.
Why the RBI’s Job Has Become More Difficult
This divergence also helps explain why exchange-rate management has become one of the Reserve Bank of India’s most complex policy challenges.
Under the classical model, a weaker currency was broadly viewed as supportive of exports.
Today, depreciation creates two opposing pressures.
On one hand, it can improve export competitiveness through the trade channel.
On the other hand, it raises the domestic cost of imported energy and intermediate goods, transmitting inflation through the economy. The Economic Survey recognises that exchange-rate movements affect the external sector through both a trade channel and a financial channel. In practice, however, imported inflation can gradually offset the competitive advantage created by a weaker currency.
The RBI therefore faces a dilemma.
Allowing the rupee to depreciate too rapidly may fuel imported inflation.
Preventing depreciation through large-scale intervention may delay the adjustment that normally reduces import demand and restores external balance.
This balancing act has become increasingly visible in recent years. During early 2026, the Reserve Bank reportedly spent around US$21 billion of foreign exchange reserves to moderate excessive currency volatility, illustrating how exchange-rate management has become an increasingly active policy challenge.
The RBI’s approach to exchange-rate management has also evolved. Whereas earlier currency management focused more explicitly on avoiding sustained appreciation of the real exchange rate, recent years have seen greater emphasis on managing volatility in the nominal exchange rate while simultaneously pursuing the inflation-targeting framework.
This is no longer simply a question of defending the rupee.
It is a question of balancing price stability, external competitiveness, financial stability, and orderly adjustment at the same time.
The Exchange Rate Is No Longer the Main Story
Perhaps the most important lesson from the Economic Survey is that exchange rates have become a symptom of deeper structural realities rather than their primary cause.
The exchange rate has not become less important.
It has become less powerful.
In the twentieth century, policymakers often used exchange rates to improve competitiveness.
In the twenty-first century, competitiveness increasingly determines the exchange rate itself.
The direction of causality has gradually begun to reverse.
A weaker rupee cannot permanently compensate for low productivity.
Nor can it offset high logistics costs, fragmented supply chains, technological dependence, or inadequate manufacturing capabilities.
Those structural factors ultimately determine whether depreciation translates into stronger exports or merely higher inflation.
This explains why the Government of India’s institutional thinking has gradually shifted away from treating exchange-rate management as the central driver of competitiveness. Instead, recent Surveys increasingly place manufacturing capability, participation in global value chains, technological upgrading, and economic complexity at the centre of India’s external-sector strategy. The exchange rate remains important, but it is increasingly viewed as reflecting the strength of these deeper economic foundations rather than substituting for them.
In other words, the question is today is not:
How can India use the exchange rate to become competitive?
The more fundamental question has become:
How can India build an economy that remains competitive regardless of short-term exchange-rate movements?
That question takes us beyond monetary policy and into the broader challenge of productivity, productive capacity, and long-term currency credibility—the foundation on which a truly strong rupee is ultimately built.
A Strong Currency Is Built in Factories, Not in Foreign Exchange Markets
Recent institutional thinking has shifted away from viewing the exchange rate as the primary driver of competitiveness. Instead, it increasingly treats currency strength as the outcome of deeper structural factors—productive capacity, manufacturing capability, and export sophistication.
The East Asian Lesson
The Economic Survey repeatedly points toward the experience of East Asian economies.
Countries such as Japan, South Korea, Taiwan and, more recently, China did not build internationally respected currencies through exchange-rate management alone.
They first built globally competitive manufacturing sectors.
Large manufacturing exports generated continuous foreign exchange earnings.
Persistent export surpluses allowed these countries to accumulate foreign assets and foreign exchange reserves over decades.
As their productive capacity expanded, international confidence in their currencies also strengthened.
In other words, currency credibility followed industrial competitiveness—not the other way around.
The East Asian experience can therefore be understood as a cumulative process.

Currency Credibility
Strong currencies were not created first.
They emerged as the outcome of decades of productive capacity building.
This institutional evolution can be understood as the Currency–Productivity Paradox.
This completely changes how we should think about exchange rates.
A strong currency is not simply defended.
It is earned.
That distinction also explains why recent Economic Surveys continue to place manufacturing at the centre of India’s long-term external strategy.
Why Manufacturing Matters More Than Services
At first glance, this conclusion may appear surprising.
After all, India’s services exports have become one of the country’s greatest economic strengths.
Information Technology services, Global Capability Centres (GCCs), financial services, consulting, and other knowledge-intensive sectors generate large foreign exchange earnings every year.
They have played a crucial role in cushioning India’s external sector.
Yet the Economic Survey also offers an important qualification.
While services provide resilience, they rarely generate the same scale of industrial ecosystems, employment linkages, supplier networks, and broad-based productivity improvements that manufacturing exports create.
A globally competitive manufacturing sector supports thousands of firms across machinery, logistics, electronics, chemicals, precision engineering, research, and component manufacturing.
Each successful exporter strengthens dozens of domestic industries simultaneously.
The broader lesson is that services should not be viewed as a complete substitute for manufacturing. Services remain an important balance-of-payments buffer, but broad-based manufacturing exports continue to provide stronger employment linkages, larger production ecosystems, and a more durable foundation for sustained currency credibility.
The distinction is subtle but important.
Services help stabilize the external sector.
Manufacturing transforms it.
The Long Game of Currency Strength
This is why recent Economic Surveys increasingly spend less time discussing exchange-rate levels and more time discussing logistics, industrial policy, research and development, Global Value Chains, infrastructure, regulatory certainty, and technological upgrading.
These may appear to be domestic policy issues.
In reality, they are also currency policies.
Reducing logistics costs lowers export prices.
Correcting inverted duty structures makes manufacturers more competitive.
Improving ease of doing business attracts globally integrated firms.
Higher private-sector R&D produces more sophisticated products.
Participation in Global Value Chains expands export capacity.
Each of these reforms gradually strengthens the economy’s ability to earn foreign exchange through production rather than through temporary financial inflows.
The Government’s evolving institutional philosophy therefore places increasing emphasis on what it describes as the “long game.” The state’s responsibility is to produce governance—efficient regulations, reliable logistics, tax certainty, and institutional stability—while the private sector produces globally competitive goods. Long-term competitiveness is created through this interaction, not through exchange-rate management alone.
The Real Foundation of a Strong Rupee
The exchange-rate paradox therefore leads to a much broader conclusion.
A weak rupee cannot permanently compensate for structural weaknesses in manufacturing.
Nor can a stronger rupee permanently undermine an economy that is highly productive.
Over long periods, currencies tend to reflect the productive strength of the economies that issue them.
Countries that consistently produce sophisticated goods, participate deeply in global value chains, maintain high savings, and generate sustained export earnings gradually build international confidence in their currencies.
Countries that rely primarily on exchange-rate adjustments eventually discover that depreciation cannot substitute for productivity.
This is perhaps the most important institutional lesson running through the recent Economic Surveys.
The debate is no longer about whether the Reserve Bank should defend a particular exchange rate.
The real challenge is whether India can build the productive capabilities that make the exchange rate increasingly less important over time.
That is the deeper meaning of the Currency–Productivity Paradox.
Ultimately, the strongest currency policy is not exchange-rate policy.
It is industrial policy.
Because over long periods, factories create exports, exports create external surpluses, surpluses create foreign assets, and foreign assets create currency credibility.
That is the deeper institutional lesson emerging from the Economic Survey.
Strong currencies are not defended into existence.
They are built.
